11 toxische Inhaltsstoffe in Sonnencremes, die du 2025 vermeiden solltest

Von Hanna Oltmanns – 15. Januar 2025

Rund um schädliche Inhaltsstoffe in Sonnencremes gibt es große Bedenken und viele Diskussionen – ein Thema, das uns bei Suntribe ständig auf Trab hält!

Sich in der Welt der Sonnencremes zurechtzufinden, kann so kompliziert sein wie das Entschlüsseln einer Geheimsprache.

Hast du dich schon mal gefragt, welche Inhaltsstoffe in Sonnencremes du vermeiden solltest?

Zum Glück haben wir einen einfachen und praktischen Leitfaden erstellt, der dir hilft, schädliche Inhaltsstoffe zu erkennen und eine Sonnencreme auszuwählen, die genauso sicher wie wirksam ist.

Warum solltest du chemische Inhaltsstoffe in Sonnencremes vermeiden?

Die Antwort ist eigentlich ganz einfach:

⇒ 63 % der Inhaltsstoffe in den beliebtesten Sonnencremes Europas gelten als gefährlich für die Gesundheit des Menschen und/oder für die Umwelt.

⇒ Immer mehr wissenschaftliche Studien zeigen, dass herkömmliche Sonnencremes hormonell wirksame Inhaltsstoffe enthalten – sie bringen dein Hormonsystem völlig durcheinander und können sogar Unfruchtbarkeit bei Männern verursachen.

⇒ Es gibt Hinweise darauf, dass bestimmte chemische UV-Filter zu einem geringeren Geburtsgewicht führen können und im Blut und Urin nachweisbar sind.

⇒ Chemische UV-Filter wurden auch in Muttermilch nachgewiesen und mit der Hirschsprung-Krankheit in Verbindung gebracht – einem angeborenen Defekt des Verdauungstrakts.

Welche Inhaltsstoffe in Sonnencremes gelten als schädlich?

Im Jahr 2021 schlug die US-amerikanische Food and Drug Administration (FDA), die für die Sicherheit von Sonnencremes zuständig ist, eine Aktualisierung der Sonnenschutz-Vorschriften vor. Dabei wurde festgestellt, dass nur zwei UV-Filter als sicher und wirksam eingestuft wurden: Zinkoxid und Titandioxid. Diese gelten nach aktuellem Stand der Wissenschaft als die sichersten Optionen.

Die meisten anderen herkömmlichen Inhaltsstoffe in Sonnencremes wurden als nicht allgemein sicher und wirksam eingestuft – teils wegen unzureichender Daten, teils wegen bedenklicher Studienergebnisse.

Welche Inhaltsstoffe in Sonnencremes solltest du während der Schwangerschaft vermeiden?

Die Schwangerschaft ist eine besonders empfindliche Phase – für dich und dein ungeborenes Kind. Als verantwortungsvolle werdende Mutter ist es wichtig, dass du bei der Auswahl deiner Pflegeprodukte, inklusive Sonnencreme, besonders achtsam bist.

Ein chemischer UV-Filter, der in der Schwangerschaft besonders kritisch gesehen wird, ist Oxybenzon – ein gängiger Bestandteil vieler herkömmlicher Sonnencremes. Studien zeigen, dass Oxybenzon schon nach einmaligem Auftragen in den Blutkreislauf gelangen kann. Es gibt Hinweise auf negative Auswirkungen auf Spermienfunktion und seine Anwesenheit in Muttermilch.

Darüber hinaus wurde Oxybenzon mit einem erhöhten Risiko für die Hirschsprung-Krankheit in Verbindung gebracht – einem schweren angeborenen Defekt, bei dem Nervenzellen im Darm fehlen.

Angesichts dieser Risiken wird schwangeren Frauen und allen, die schwanger werden möchten, dringend geraten, Sonnencremes mit Oxybenzon zu meiden. Das schützt nicht nur die Gesundheit des Babys, sondern auch deine eigene.

Auch wenn Oxybenzon als der gefährlichste Inhaltsstoff in Sonnencremes gilt, solltest du während der Schwangerschaft noch auf einige weitere Stoffe verzichten.

Damit du schädliche Inhaltsstoffe in Sonnencremes und Hautpflegeprodukten leichter erkennen kannst, haben wir hier eine Übersicht der besonders bedenklichen Stoffe zusammengestellt.

Die folgende Liste ist nach dem Gefährdungspotenzial sortiert – basierend auf der Einstufung durch die Environmental Working Group (EWG). Diese Inhaltsstoffe überschreiten außerdem die Sicherheitsgrenzwerte der US-amerikanischen Lebensmittel- und Arzneimittelbehörde (FDA).

Schädliche aktive Inhaltsstoffe in Sonnencremes – HOHES RISIKO

Zum Vergleich: Zinkoxid erhält in Cremes eine EWG-Sicherheitsbewertung von 1 (höchstmöglich) und in Sprays/Pudern eine Bewertung von 3. Die Skala reicht von 1 (am sichersten) bis 10 (am bedenklichsten).

Wegen ihrer hohen Toxizität wurden die folgenden hochriskanten chemischen UV-Filter bereits in 7 Ländern und Regionen weltweit verboten:

1. Oxybenzon / Benzophenon-3 (BP-3)

EWG-Sicherheitsbewertung: 8
Hormoneller Schadstoff: wirkt wie Östrogen, wurde im Blutkreislauf nachgewiesen, in Verbindung gebracht mit Unfruchtbarkeit bei Männern.
Hemmt das Wachstum von Korallenlarven und verursacht Korallenbleiche

2. Octinoxat / Octylmethoxycinnamat (OMZ)

Weitere schädliche Inhaltsstoffe in Sonnencremes – Mittleres Risiko

1. Homosalat

EWG-Sicherheitsbewertung: 2–4
Möglicher hormoneller Schadstoff: stört Fortpflanzungshormone
Beeinträchtigt das Wachstum von Meerestieren, z. B. Seeorchideen und Algen
Hergestellt aus Salicylsäure
Kann Geburtsfehler bei Menschen und Fischen verursachen und wird für Schwangere nicht empfohlen.

2. Octisalat / Ethylhexylsalicylat

3. Octocrylen / 2-Ethylhexylester

EWG-Sicherheitsbewertung: 2–3
Hohe Rate an phototoxischen Kontaktallergien: Kann zu Hautreizungen und Ekzemen führen, wenn Octocrylen in Verbindung mit Sonnenlicht auf die Haut trifft.
Erste Hinweise auf Bioakkumulation, z. B. in Gehirn und Leber von Zebrafischen, mit möglichen Auswirkungen auf Organ- und Entwicklungsprozesse.

Weitere schädliche Inhaltsstoffe in Sonnencremes – GERINGES RISIKO

1. Avobenzon

EWG-Sicherheitsbewertung: 1–2
Als Einzelstoff nicht photostabil: Zerfällt bei UV-Lichtkontakt und bildet dabei ökotoxische Nebenprodukte.
Daher wird es häufig mit Stabilisatoren wie Octisalat kombiniert, der weiter oben auf dieser Liste erwähnt wird.

Neben schädlichen aktiven Inhaltsstoffen in Sonnencremes gibt es auch inaktive Inhaltsstoffe, die bisher nicht reguliert sind – obwohl sie ein erhebliches Risiko für die öffentliche Gesundheit darstellen. Hier findest du eine Liste solcher inaktiven Stoffe, auf die du in deinen Produkten unbedingt achten solltest.

2. Parabene

Parabene sind in den meisten Kosmetikprodukten enthalten. Sie dienen hauptsächlich dazu, die Haltbarkeit von Produkten zu verlängern, indem sie das Wachstum von Bakterien verhindern.. Das klingt erst mal gut – aber Parabene werden auch mit Brustkrebs in Verbindung gebracht, da sie die Zellmechanismen in Brustgewebe beeinflussen können. Einige Parabene wurden bereits in bestimmten Ländern verboten. Trotzdem sind Parabene wie Ethylparaben, Methylparaben und andere Stoffe, die auf -paraben enden, weiterhin in Kosmetika zugelassen.

3. Bemotrizinol (auch bekannt als Tinosorb S)

Bemotrizinol wird häufig in Sonnencremes verwendet, da es sowohl UVA- als auch UVB-Strahlen absorbieren kann. Es ist in Europa und Australien zugelassen. In den USA hingegen hat die FDA mehrere Zulassungsanträge für Bemotrizinol abgelehnt, da nicht genügend Daten vorliegen, um seine Sicherheit und Wirksamkeit offiziell zu bestätigen.

4. Retinylpalmitat

Retinylpalmitat ist eine Form von Vitamin A, die möglicherweise zu Hautschäden und Krebs führen kann.. Es gibt Hinweise darauf, dass Retinylpalmitat das Wachstum von Krebszellen beschleunigen kann, wenn es auf der Haut unter Sonnenlicht angewendet wird.Eine Studie des Norwegischen Wissenschaftlichen Komitees für Lebensmittelsicherheit stellte fest, dass übermäßige Mengen an Vitamin A gesundheitliche Probleme wie Leberschäden, Haarausfall und Osteoporose (Knochenschwund) verursachen können.

5. Titandioxid (nano)

Nano-Titandioxid ist in vielen Kosmetikprodukten enthalten, auch in Sonnencremes. Trotzdem wurde es auf Grundlage von Tierversuchen zur Inhalation als möglicherweise gesundheitsschädlich für den Menschen eingestuft.. Es gilt außerdem als möglicherweise krebserregend in Pulverform oder als Spray, wie es z. B. in Sonnencremesprays, Puder mit Lichtschutzfaktor oder Lidschatten vorkommt.

6. Methylisothiazolinon (MI)

Studien deuten darauf hin, dass MI neurotoxisch sein und allergische Reaktionen auslösen kann.. Der häufige Einsatz von MI in Sonnencremes ist bedenklich, da Nutzer*innen so möglicherweise hohen Konzentrationen ausgesetzt sind.

Zum Glück haben viele Länder reagiert und bereits mehrere dieser problematischen Sonnencreme-Inhaltsstoffe verboten. Hawaii und Palau haben die gefährlichsten UV-Filter verbannt, um Korallenriffe zu schützen. Auch mehrere Nationalparks in Mexiko haben risikoreiche Inhaltsstoffe untersagt, um ihre Umwelt zu bewahren. Insgesamt haben bislang sieben Reiseziele weltweit toxische Sonnenschutzfilter verboten.

Die Lösung: Greif lieber zu einer mineralischen Sonnencreme

Im Allgemeinen sind mineralische Sonnencremes deutlich unbedenklicher – für dich und den Planeten. Sie enthalten kein Risiko für die menschliche Gesundheit, wenn sie mit den richtigen Inhaltsstoffen formuliert sind. Zusätzlich bieten sie praktische Vorteile wie z. B. sofortigen Schutz ohne Einwirkzeit.

Was ist der Unterschied zwischen chemischen und mineralischen Sonnencremes?

Mineralische und chemische Sonnencremes wirken auf ganz unterschiedliche Weise. Chemische Sonnencremes basieren auf UV-Filtern wie Oxybenzon oder Avobenzon und dringen in die Haut und sogar den Blutkreislauf ein.

Viele wissen nicht, dass chemische Sonnencremes vor dem Sonnenkontakt aufgetragen werden müssen. Sie brauchen etwa 20–30 Minuten, um zu wirken, da sie erst in die Haut eindringen müssen. Chemische Sonnencremes verändern die Eigenschaften deiner Hautzellen von innen heraus, um dich vor UV-Strahlung zu schützen.

Mineralische Sonnencremes dagegen wirken sofort – sie legen sich wie ein Schutzschild auf deine Haut und reflektieren das Sonnenlicht.

Sie schützen dich ab dem ersten Moment nach dem Auftragen – was besonders praktisch ist, wenn du z. B. mit deinen Kindern am Strand bist und gleich ins Wasser willst.

Außerdem reizen mineralische Sonnencremes die Haut viel weniger, da sie in der Regel mehr natürliche Inhaltsstoffe enthalten. Sie sind daher besonders gut geeignet bei sensibler Haut, Allergien oder für Babys.

Warum solltest du eine mineralische Sonnencreme verwenden?

⇒ Mineralische Sonnencremes schützen dich besser vor UVB- und UVA-Strahlen, da sie eine physische Barriere zwischen dir und der Sonne bilden.

⇒ Mineralische Sonnencremes sind hautfreundlicher, da sie in der Regel mit weniger und natürlicheren Inhaltsstoffen formuliert sind.

⇒ Mineralische Sonnencremes sind auch umweltfreundlicher – vor allem, wenn sie Zinkoxid oder Titandioxid ohne Nanopartikel enthalten. Diese gelten als die aktuell sichersten Optionen für Mensch und Meer.

⇒ Moderne mineralische Sonnencremes lassen dich nicht mehr wie ein Geist aussehen – viele fortschrittliche Formulierungen passen sich deinem Hautton an oder sind sogar durchsichtig beim Auftragen.

Tipps: So findest du eine sichere Sonnencreme

Tipp 1: Überprüfe die Unbedenklicheit deiner Sonnencreme

Manche Plattformen machen es dir viel leichter, eine sichere Sonnencreme zu finden. Du kannst zum Beispiel die Bewertung der EWG (Environmental Working Group) als Orientierung nutzen. Gib einfach den Namen der Marke oder des Produkts ein – dort findest du genaue Informationen zur Sicherheitsbewertung des Produkts und jedes einzelnen Inhaltsstoffes.

Tipp 2: Achte auf alle Inhaltsstoffe, nicht nur auf den UV-Filter

Neben den aktiven Inhaltsstoffen (also den UV-Filtern) solltest du auch auf andere Bestandteile achten.

Wir empfehlen dir, auf Produkte mit einem klaren und verständlichen Etikett zu achten – das bedeutet: keine schwer erkennbaren Namen, keine synthetischen Zusätze.

Natürlich kann ein Inhaltsstoff auch sicher sein, wenn du ihn nicht erkennst – besonders, wenn er unter ihrem INCI-Namen (der internationalen Standardbezeichnung für kosmetische Inhaltsstoffe) gelistet ist.

Zwei hilfreiche Apps, mit denen du schnell und einfach sichere Inhaltsstoffe erkennen kannst: Think Dirty & CodeCheck.

Tipp 3: Verstehe das Etikett deiner Sonnencreme

Die Angaben auf Sonnencremes können ziemlich verwirrend sein – darum ist es gut zu wissen, auf welche Begriffe du achten solltest:

⇒ Breitbandspektrum-Schutz

Breitbandspektrum-Schutz bedeutet, dass Sonnencreme sowohl vor UVA- als auch UVB-Strahlen schützt. Das ist besonders wichtig, denn UVA- und UVB-Strahlen schädigen deine Haut, und der Lichtschutzfaktor (LSF) gibt nur den UVB-Schutz an. UVA-Strahlen dringen sogar noch tiefer in deine Haut ein als UVB-Strahlen und können langfristige Hautschäden verursachen, etwa vorzeitige Hautalterung und Hautkrebs.

⇒ LSF (Lichtschutzfaktor)

Jede Sonnencreme, die du verwendest, sollte selbstverständlich einen LSF enthalten! Laut der FDA solltest du eine Sonnencreme mit mindestens LSF 15 wählen, um ausreichend geschützt zu sein.. Wenn du mehr darüber erfahren willst, wie der LSF funktioniert, schau dir gern unseren Artikel über LSF, UVA & UVB auf unserer Website an.

Gut zu wissen: Der Unterschied im Schutz zwischen LSF 30 und LSF 50 beträgt nur etwa 1 Prozentpunkt!

⇒ Wasserfestigkeit

Achte darauf, eine Sonnencreme mit ausreichender Wasserfestigkeit zu wählen! Das ist besonders wichtig, wenn du schwimmen gehst oder viel schwitzt – die Wasserfestigkeit sorgt dafür, dass deine Sonnencreme dich trotzdem weiterhin schützt. Das Angabe zur Wasserfestigkeit zeigt dir, wie lange die Sonnencreme beim Kontakt mit Wasser oder Schweiß wirkt. Es gibt zwei Angaben: 40 Minuten („wasserfest“) oder 80 Minuten („sehr wasserfest“).. Je nachdem, was du vorhast, solltest du also eine passende Sonnencreme auswählen.

Wir hoffen, dass dir diese Tipps helfen, eine Sonnencreme zu finden, mit der du dich rundum sicher fühlst – für dich und für unseren Planeten. Wenn du dich an diesen Hinweisen orientierst und auf potenziell problematische Inhaltsstoffe achtest, findest du ganz sicher eine sichere Sonnencreme – für dich und die Natur!

Der ultimative Guide für Kindersonnencreme

Von Hanna Oltmanns - März 7, 2025

Wir alle wollen unsere Kinder so gut wie möglich schützen, und wenn es um Sonnenschutz geht, ist Sonnencreme an einem heißen Sommertag ein Muss. Doch bei so vielen Optionen – mineralisch vs. chemisch, LSF 30 vs. LSF 50, wasserfest oder nicht – wie wählst du das richtige Produkt für deine Familie?

Wenn du neu in dem Thema bist, kann es überwältigend sein, sich durch die verschiedenen Formeln, LSF-Stufen und Sicherheitsbedenken zu navigieren.

Wusstest du, dass LSF 50 nur 1 % mehr UVB-Strahlen blockiert als LSF 30? Oder dass manche chemischen UV-Filter mit hormonellen Störungen in Verbindung gebracht werden?

Deshalb haben wir diesen Sonnenschutz-Guide für Kinder erstellt – eine vollständige Ressource, die die am häufigsten gestellten Fragen beantwortet. Wir behandeln alles von der Auswahl der sichersten Sonnencreme und der richtigen Anwendung bis hin zu zusätzlichen Tipps zum Sonnenschutz und Strategien für Schatten. Außerdem erklären wir dir, was du tun kannst, wenn dein Kind doch einmal einen Sonnenbrand bekommt – damit du auf jede Situation bestens vorbereitet bist.

Warum sind mineralische Sonnencremes besser für Kinder als chemische?

Mineralischer Sonnenschutz bietet eine sichere und verlässlichere Option für Kinder, da er sich auf die Haut legt und UV-Strahlen physikalisch blockiert – anstatt sie wie chemische Sonnencremes zu absorbieren. Die wichtigsten Inhaltsstoffe sind in der Regel Zinkoxid und Titandioxid, die sowohl gegen UVA- als auch UVB-Strahlen breitbandigen Schutz bieten und sofort nach dem Auftragen wirken.

Im Gegensatz dazu enthalten chemische Sonnencremes häufig synthetische UV-Filter, die in die Haut eindringen können, Hormone stören und Reizungen verursachen – insbesondere bei empfindlicher und sich entwickelnder Haut. Chemische Sonnencremes brauchen außerdem etwa 20 Minuten, bis sie wirken, weshalb sie vor dem Sonnenkontakt aufgetragen werden müssen.

Da mineralische Sonnencremes sanftere, stabilere Inhaltsstoffe verwenden und im Allgemeinen frei von synthetischen Zusätzen sind, stellen sie eine sicherere und wirksamere Wahl zum Schutz von Kindern vor der Sonne dar.

Welche Inhaltsstoffe sollte ich in Sonnencremes für Kinder vermeiden?

Nicht alle Sonnencremes sind gleich, und einige enthalten Inhaltsstoffe, die mehr schaden als nützen – besonders für Kinder, deren Haut empfindlicher und aufnahmefähiger ist als die von Erwachsenen. Oxybenzon, Octinoxat und Homosalat gehören zu den bedenklichsten chemischen UV-Filtern, da sie mit hormonellen Störungen und Hautreizungen in Verbindung gebracht werden.

Weitere Inhaltsstoffe, die du vermeiden solltest,Parabene, synthetische Duftstoffe und bestimmte Konservierungsstoffe, die allergische Reaktionen und langfristige Gesundheitsrisiken auslösen können.Diese Chemikalien stehen im Verdacht, hormonell wirksam zu sein, die Hautempfindlichkeit zu erhöhen und in einigen Fällen potenziell krebserregend zu sein.

Zusätzlich könnten nanoskalige Partikel aus Zinkoxid oder Titandioxid klein genug sein, um in die Haut einzudringen – daher solltest du sie vermeiden, da es derzeit keine ausreichenden Belege dafür gibt, dass ihre Anwendung unbedenklich ist.

Für eine vollständige Liste der giftigsten Sonnenschutz-Inhaltsstoffe, die du meiden solltest, schau dir unseren ausführlichen Leitfaden an: 11 toxische Sonnencreme-Inhaltsstoffe, die du 2025 vermeiden solltest.

Welcher LSF ist für Kinder am sichersten?

Viele Eltern gehen davon aus, dass ein höherer LSF automatisch besseren Schutz bedeutet. Da die LSF-Skala jedoch nicht linear ist, stimmt das nicht. Der Unterschied zwischen LSF 30 und LSF 50 beträgt nur einen Prozentpunkt – LSF 30 blockiert 97 % aller UVB-Strahlen, während LSF 50 98 % blockiert.

UVB-Strahlen sind verantwortlich für sichtbare Sonnenschäden wie Sonnenbrand, während UVA-Strahlen tiefer in die Haut eindringen und dort langfristige Schäden wie vorzeitige Hautalterung und ein erhöhtes Hautkrebsrisiko verursachen. Da LSF nur den UVB-Schutz misst, ist es wichtig, eine Sonnencreme mit Breitband-Schutz zu wählen, die sowohl gegen UVA- als auch UVB-Strahlen schützt.

“Korrekt aufgetragene Sonnencreme mit LSF 50 blockt 98% der UVB-Strahlen, während eine Sonnencreme mit LSF 30 vor 97% der UVB-Strahlen schützt – der Unterschied beträgt lediglich einen Prozentpunkt.”

Für Kinder können sowohl LSF 30 als auch LSF 50 eine sichere Wahl sein – vorausgesetzt, es handelt sich um eine mineralische Sonnencreme, die Breitband-Schutz bietet und wie empfohlen aufgetragen und erneut aufgetragen wird.

Wenn du tiefer in das Thema LSF, UVA- und UVB-Schutz eintauchen möchtest, findest du hier unseren vollständigen Leitfaden: Der Unterschied zwischen LSF 30 und LSF 50.

Ist Suntribe Sonnencreme sicher für Babys und Kleinkinder?

Ja, das sind sie! Alle Suntribe Sonnencremes werden aus 100 % natürlichen und biologischen Inhaltsstoffen hergestellt, was sie zu einer sicheren Wahl selbst für die empfindlichste Haut macht. Sobald dein Baby älter als 6 Monate ist, gilt Sonnencreme laut ärztlicher Empfehlung in der Regel als unbedenklich. Vor diesem Alter ist es am besten, auf andere Schutzmaßnahmen wie Hüte, lange Kleidung und Schatten zu setzen, um die Kleinen vor der Sonne zu schützen.

Für Kleinkinder und Babys über 6 Monate bieten Suntribe Sonnencremes Breitband-Schutz mit Nicht-Nano-Zinkoxid. Dieser bildet eine schützende Barriere auf der Haut und blockiert sowohl UVB- als auch UVA-Strahlen sofort. Dennoch sollte Sonnencreme immer mit weiteren Sonnenschutzmaßnahmen wie Hüten, Kleidung, Sonnenbrillen und Schatten kombiniert werden – für einen sicheren UV-Schutz.

„Für Kleinkinder und Babys über 6 Monate bieten Suntribe Sonnencremes hervorragenden Schutz vor UVB- und UVA-Strahlen.“

Kann ich meine eigene Sonnencreme bei meinem Kind verwenden oder braucht es eine spezielle Formel?

Nicht alle Sonnencremes sind für Kinder geeignet, da Kinderhaut empfindlicher und aufnahmefähiger ist als die Haut von Erwachsenen. Viele herkömmliche Sonnencremes enthalten Inhaltsstoffe, die Reizungen oder allergische Reaktionen auf der jungen Haut auslösen können.

Eine gute Möglichkeit, zu überprüfen, ob eine Sonnencreme für Kinder geeignet ist, besteht darin, die Inhaltsstoffe mithilfe von Apps wie INCI Beauty oder Yuka zu analysieren, die Produktformulierungen auf potenzielle Risiken hin untersuchen.

⇒ Übrigens werden alle Suntribe Sonnencremes mit 100 % natürlichen und biologischen Inhaltsstoffen hergestellt und sind selbst für die empfindlichste Haut sicher – eine sorgenfreie Wahl für die ganze Familie.

Für eine detaillierte Erklärung, wie beide Apps funktionieren und welche Bewertungen Suntribe Sonnencremes erhalten haben, schau dir unseren Artikel zu diesem Thema an: Die sichere Wahl: So schneiden Suntribe-Produkte bei INCI Beauty & Yuka ab.

Wie viel Sonnencreme sollte ich meinem Kind auftragen?

Um einen angemessenen Schutz zu gewährleisten, trage etwa einen halben Teelöffel Sonnencreme auf das Gesicht und den Hals deines Kindes auf und etwa zwei Esslöffel für den ganzen Körper. Diese Menge entspricht der 2 mg/cm²-Regel, die beim LSF-Test verwendet wird.

Ein guter Trick ist es, zunächst kleine Tupfen Sonnencreme auf die Haut zu geben und diese dann gleichmäßig in kreisenden Bewegungen zu verteilen, um vollständige Abdeckung zu erreichen. Vergiss nicht häufig ausgelassene Stellen wie die Ohren, den Nacken, die Fußrücken und die Hände.

Wie oft sollte ich bei meinem Kind Sonnencreme nachtragen?

Sonnencreme sollte mindestens alle zwei Stunden erneut aufgetragen werden, um einen guten Schutz aufrechtzuerhalten. Wenn dein Kind schwimmt, schwitzt oder sich mit einem Handtuch abtrocknet, sollte sofort nach dem Kontakt mit Wasser nachgecremt werden – auch wenn die Sonnencreme wasserfest ist.

Mineralische Sonnencremes mit Zinkoxid oder Titandioxid ohne Nanopartikel legen sich auf die Haut, anstatt einzuziehen. Eine sichtbare Schicht kann also ein Hinweis darauf sein, wann es Zeit ist nachzucremen. Um eine gleichmäßige Abdeckung sicherzustellen, stelle dir einen Wecker oder mache das Nachcremen zu einem festen Bestandteil der Routine deines Kindes – besonders an langen Tagen im Freien.

Wie kann ich mein Kind sonst noch schützen – außer mit Sonnencreme?

Sonnencreme ist wichtig, aber da keine Sonnencreme zu 100 % wirksam ist, sollte sie nicht die einzige Quelle des UV-Schutzes sein. Der beste Schutz ergibt sich durch eine Kombination aus sonnensicheren Gewohnheiten:

⇒ Schützende Kleidung tragen – leichte, langärmlige Shirts, Hüte und Sonnenbrillen mit UV-Schutz verwenden und Kleidung sowie Badeanzüge mit UPF (Ultraviolett-Schutzfaktor) in Betracht ziehen.

⇒ Schatten suchen – Halte dein Kind während der Hauptsonnenzeiten (10–16 Uhr), wenn die UV-Strahlung am stärksten ist, im Schatten auf – z. B. mit Sonnenschirmen, Bäumen oder Sonnensegeln, wenn ihr draußen Zeit verbringt.

⇒ Zeitlich gut planen – Lege Aktivitäten im Freien möglichst auf die frühen Morgenstunden oder späten Nachmittage, wenn die Sonne weniger intensiv ist.

⇒ Für Flüssigkeitszufuhr sorgen – Sonnenexposition kann zu Dehydration führen, also achte darauf, dass dein Kind über den Tag verteilt ausreichend Wasser trinkt.

Kann Sonnencreme bei Kindern einen Vitamin-D-Mangel verursachen?

Das ist eine häufige Sorge, aber Studien zeigen, dass die Verwendung von Sonnencreme den Vitamin-D-Spiegel bei Kindern und Erwachsenen nicht signifikant beeinflusst. Auch wenn Sonnencreme die Menge an UVB-Strahlen, die die Haut erreichen, reduziert – also jene Strahlen, die für die Vitamin-D-Produktion verantwortlich sind – produziert der Körper bei regelmäßiger Bewegung im Freien dennoch ausreichend Vitamin D.

Studien haben gezeigt, dass auch bei korrekter Anwendung von Sonnencreme genug UVB-Strahlen durch die Haut dringen können, um die Vitamin-D-Synthese zu ermöglichen. Zum Beispiel: Wenn du bei deinem Kind eine Sonnencreme mit LSF 30 aufträgst, blockiert diese 97 % der UVB-Strahlen – 3 % gelangen also noch in die Haut und ermöglichen die Produktion von Vitamin D.

Außerdem kann Vitamin D auch über Lebensmittel wie fetten Fisch, Eier und angereicherte Milchprodukte aufgenommen werden.

Da UV-Schäden sich mit der Zeit summieren, ist ungeschützter Aufenthalt in der Sonne zur Vitamin-D-Bildung keine sichere Methode. Die beste Strategie? Verwende eine Sonnencreme mit Breitband-Schutz, fördere Aktivitäten im Freien und achte auf eine ausgewogene Ernährung, um sicherzustellen, dass dein Kind genug Vitamin D bekommt – ohne das Risiko von Sonnenbrand und langfristigen Hautschäden.

„Selbst beim Auftragen von Sonnencreme mit LSF 30 erreichen etwa 3 % der UVB-Strahlen weiterhin die Haut, sodass der Körper genügend Vitamin D produzieren kann.“

Wenn du weitere Antworten zu diesem Thema suchst, findest du in unserem ausführlichen Artikel mehr Informationen: Beeinflusst LSF die Vitamin-D-Aufnahme?

Was kann ich tun, wenn mein Kind einen Sonnenbrand bekommt?

Wenn dein Kind einen Sonnenbrand hat, solltest du schnell handeln, um die Haut zu beruhigen und weitere Schäden zu vermeiden:

⇒ Die Haut kühlen – Lege ein kühles, feuchtes Tuch auf oder lasse dein Kind ein lauwarmes Bad nehmen, um Hitze und Beschwerden zu lindern. Vermeide Eis, da es den Sonnenbrand verschlimmern kann.

⇒ Für Flüssigkeit sorgen – Sonnenbrand entzieht der Haut Feuchtigkeit, also achte darauf, dass dein Kind ausreichend Wasser trinkt, um den Heilungsprozess zu unterstützen.

⇒ Mit Aloe Vera beruhigen – Trage reines Aloe-Vera-Gel oder eine sanfte, parfümfreie Feuchtigkeitscreme auf, um Reizungen zu lindern. Vermeide Produkte auf Erdölbasis, da sie Wärme einschließen können.

⇒ Haut bedecken und Sonne meiden – Ziehe deinem Kind lockere, atmungsaktive Kleidung an und halte es aus direkter Sonneneinstrahlung fern, bis der Sonnenbrand abgeheilt ist.

⇒ Auf ernste Symptome achten – Wenn dein Kind Blasen, Fieber, Schüttelfrost, Übelkeit oder Schwindel entwickelt, könnte es sich um einen schwereren Sonnenbrand handeln. Konsultiere in diesem Fall unbedingt einen Arzt.

Wie wähle ich die richtige Sonnencreme für mein Kind aus?

Wenn du eine Sonnencreme für dein Kind auswählst, achte darauf, dass sie sicher, wirksam und langanhaltend schützt. Hier sind einige wichtige Faktoren, die du beachten solltest:

✔️ Breitbandspektrum-Schutz – Achte darauf, dass die Sonnencreme sowohl vor UVA- als auch vor UVB-Strahlen schützt, um Sonnenbrand und langfristige Hautschäden zu vermeiden.

✔️ Mineralische UV-Filter – Wähle eine Sonnencreme mit Zinkoxid oder Titandioxid ohne Nanopartikel. Diese legen sich auf die Haut und reflektieren UV-Strahlen, anstatt wie chemische Filter in die Haut einzudringen.

✔️ LSF 30–50 – LSF 30 blockiert 97 % der UVB-Strahlen, LSF 50 blockiert 98 %. Höhere LSF-Werte bieten nur geringfügig mehr Schutz, deshalb ist regelmäßiges Nachcremen wichtiger als ein extrem hoher LSF.

✔️ Wasserfestigkeit – Wenn dein Kind schwimmt oder stark schwitzt, wähle eine wasserfeste Sonnencreme:

⇒ 40 Minuten Wasserfestigkeit für allgemeines Spielen im Freien

⇒ 80 Minuten Wasserfestigkeit für längere Zeit im Wasser

✔️ Hypoallergen & parfümfrei – Vermeide synthetische Duftstoffe, Konservierungsstoffe und chemische UV-Filter, die Hautreizungen verursachen können – besonders bei Kindern mit empfindlicher Haut.

Are high SPF sunscreens just a joke?

Are high SPF sunscreens just a joke?

By Karl Roos - May 1, 2025

The truth about high SPF sunscreens

In the world of sunscreen, how things sound and reality are not always the same thing. SPF 100 might sound like the ultimate sun protection, but in reality, the difference between SPF 50 and SPF 100 is barely noticeable—while the risks and misleading claims are much greater.

Why high SPF sunscreens aren’t more effective

Most people assume that SPF 100 provides double the protection of SPF 50, but that’s not the case at all. SPF ratings measure the percentage of UVB rays blocked, but the increase in protection above SPF 30 is marginal. This is explained by the fact that the scale was firstly made with SPF 30 as the maximum value:

SPF 30 blocks 97% of UVB rays (Which dermatologists agree is enough for all situations of sun protection)
SPF 50 blocks 98%
SPF 100 blocks 99% (at most)

That’s just a 1% difference between SPF 30 and 50 and another 1% between SPF 50 and SPF 100, but the marketing makes it seem like a game-changer. Things are clearly not always as they look.

The hidden problem: UVA rays

SPF ratings only measure UVB protection (the rays responsible for sunburn), not UVA rays, which penetrate deeper into the skin and cause long-term damage, premature aging, and increased skin cancer risk.

Unlike UVB rays, which cause visible burns, UVA rays are more insidious—they penetrate deeper into the skin, contributing to photoaging, wrinkles, and potentially DNA damage that increases cancer risk over time.

This means that a simple SPF rating, be it 30 or 100, actually does not tell you about the UVA protection of that sunscreen.

How Is UVA protection measured?

UVA protection is assessed using different standards, depending on the regulatory framework of a country. The most common method include:

⇒ The UVA-PF Test (Persistent Pigment Darkening – PPD Test): Measures how much UVA radiation is needed to produce prolonged darkening of the skin. A product must provide at least 1/3 of the labeled SPF in UVA protection to qualify as broad-spectrum.

However, studies by the Environmental Working Group (EWG) have shown that many high SPF sunscreens fail to meet adequate UVA protection standards. In some cases, high SPF products only provide a quarter of the UVA protection needed, leaving the skin highly vulnerable.

The false sense of security

High SPF sunscreens encourage risky sun behavior. People tend to apply less sunscreen, reapply less frequently, and stay in the sun longer because they think they’re getting significantly more protection. In reality, they’re increasing their exposure to harmful UVA radiation without realizing it.

The EWG also found that many high SPF products didn’t even deliver the UVB protection stated on their labels—some only provided 42-69% of the promised protection. This issue was significantly more prevalent in high SPF sunscreens (SPF 50+) than low SPF sunscreens. So not only does the high SPF number give a false sense of security, it’s also significantly more likely to not even provide the protection that it does state.

The health risks of high SPF sunscreens

To achieve SPF levels above 50, manufacturers often increase the concentration of chemical UV filters.

This can lead to:

⇒ Skin irritation & allergic reactions

⇒ Hormone disruption from certain chemical filters

⇒ Higher absorption of chemicals into the bloodstream

⇒ Potential endocrine disruption: Some chemical UV filters, such as oxybenzone and octinoxate, have been found to mimic hormones and interfere with the body’s natural hormonal balance, potentially leading to reproductive issues and thyroid dysfunction.

⇒ Increased risk of skin sensitivity: Certain high SPF formulations contain higher concentrations of active ingredients that may trigger skin irritation, allergic reactions, and contact dermatitis, especially in individuals with sensitive skin.

⇒ Chemical accumulation in the body: Research has shown that some sunscreen chemicals can be detected in the bloodstream long after application, raising concerns about their long-term effects on human health.

Why more chemical filters are used in high SPF sunscreens

Manufacturers must use higher concentrations of chemical UV filters to achieve SPF levels above 50. This is because no single ingredient can block enough UVB rays on its own to reach SPF 100, so a combination of multiple filters is necessary. These higher concentrations come with increased risks, including greater chances of skin irritation, allergic reactions, and hormone disruption.

This practice is not necessarily in the best interest of the consumer but is often a marketing strategy. High SPF labels give the illusion of superior protection, convincing consumers that SPF 100 is significantly better than SPF 50. However, as previously mentioned, the difference in UVB protection is minimal, while the risks and misleading claims are far greater. The increased use of chemicals also raises concerns about long-term health impacts and environmental damage.

The environmental impact

Most high SPF sunscreens rely on chemical UV filters that have been linked to coral reef damage and marine toxicity. Several destinations, including Hawaii and Palau, have banned certain sunscreen chemicals due to their harmful effects on marine life.

In fact, the majority of SPF 50+ sunscreens contain ingredients such as oxybenzone, octinoxate, and octocrylene, which have been deemed illegal in places like Hawaii and Palau due to their role in coral bleaching and aquatic toxicity. These chemicals have been found in marine ecosystems, affecting the reproductive health of marine life and contributing to environmental degradation.

Because achieving SPF levels above 50 requires increasing the concentration of these chemical filters, most high SPF sunscreens are not compliant with the environmental regulations in these regions. This suggests that the pursuit of SPF 100 is not only unnecessary but also actively harmful to marine biodiversity.

Unreliable SPF testing

SPF testing isn’t standardized across labs, leading to inconsistent and often misleading results. Studies have found that minor variations in application can result in SPF 100 sunscreens testing anywhere from SPF 37 to SPF 75 in real-world conditions. Further contributing to the uncertain nature of using high SPF products.

What do experts recommend?

Dermatologists and organizations like the FDA and EWG recommend using broad-spectrum sunscreen with SPF between 30 and 50, reapplying every two hours, and using additional protective measures such as hats, sunglasses, and seeking shade.

The case for an SPF 50+ cap

The FDA has long considered SPF values above 50 to be “inherently misleading.” Most countries have already capped SPF at 50+. In 2011, the FDA proposed banning labels higher than SPF 50, but in 2021, they suggested increasing the limit to SPF 60+.

The EWG and other experts argue that capping SPF at 50+ would prevent misleading claims and encourage better sun protection habits.

The bottom line

SPF 100 isn’t the superhero it pretends to be. It provides minimal extra protection, encourages risky sun behavior, contains more potentially harmful chemicals, and misleads consumers into a false sense of security. Instead of chasing high SPF numbers, opt for broad-spectrum SPF 30-50, reapply regularly, and use sun-protective clothing for the best defense against sun damage.

The ultimate guide to choosing a pregnancy-safe sunscreen

By Hanna Oltmanns - April 1, 2025

Being pregnant is an amazing and truly breathtaking experience that many mothers wouldn’t trade for anything in the world. However, it is also a very vulnerable stage, both for mother and baby and during this season, an extra sense of care is required to keep both of them safe. Sun protection is an important part of this – but how do you find a pregnancy-safe sunscreen that truly protects without exposing you to harmful chemicals?

Why should you use sun protection during pregnancy?

During pregnancy, hormonal changes make the skin more sensitive to UV radiation, increasing the risk of hyperpigmentation, premature aging, and skin damage. Hormonal shifts can increase melanin production and excessive sun exposure without protection can increase these pigmentations, making it harder for them to fade after pregnancy. Besides that, a mothers skin becomes a lot more sensitive during that time, increasing the risk of sunburn and lasting skin damage.

What is the problem with chemical sunscreens?

Chemical sunscreens contain synthetic UV-filters like oxybenzone, octinoxate, and avobenzone which absorb UV radiation and convert it into heat to prevent skin damage. While they are effective in protection against sunburn, they have been shown to have a negative effect on human health and put pregnant women and their unborns at risk.

Studies have found that oxybenzone and other chemical UV filters can penetrate the skin and enter the bloodstream where they accumulate over time and be detected in urine, amniotic fluid, and even in breast milk.

These chemicals belong to a group of endocrine-disrupting chemicals, which means they have the potential to mimic or interfere with the body’s natural hormone functions, particularly estrogen and progesterone, which are crucial for a healthy pregnancy.

What are endocrine disruptors and where can they be found?

Endocrine disruptors (EDCs) are chemicals that interfere with the body’s hormonal system, either by mimicking, blocking or altering natural hormone functions. These disruptions can lead to a range of health issues, including reproductive problems, developmental disorders, metabolic imbalances, and increased risk of hormone-related diseases, such as endometriosis.

EDCs can be found in everyday products, including sunscreens, cosmetics, plastic packaging, household cleaning products and even food and water. In personal care products, common endocrine disrupters include parabens, phthalates, and chemical UV filters like oxybenzone and octinoxate.

As these chemicals can be absorbed through the skin, long term exposure can lead to accumulation in the body.

What is Endometriosis and why can it be linked to sunscreen?

Endometriosis is a chronic inflammation condition, where tissue, similar to the uterine lining grows outside the uterus. It affects up to 15% of all women globally and can lead to severe pain, infertility, and hormonal imbalances. Since endometriosis is an estrogen-dependent disease, anything that affects estrone levels has the potential to influence its development or severity, including sunscreens with chemical UV-filters.

Recent studies have raised concerns that endocrine disruptors commonly found in sunscreens and cosmetics, may contribute to a higher risk of endometriosis. Research suggests that women who frequently use beauty products containing EDCs tend to have higher levels of these chemicals in their bodies and are more likely to develop endometriosis. Since chemical sunscreens contain UV-filters like oxybenzone, octinoxate, and avobenzone – known endocrine disruptors – daily sunscreen use could be a significant source of exposure.

What is Hirschsprung's disease and why can it be linked to sunscreens?

Hirschsprung’s disease is a birth defect that affects a baby’s intestines, making it hard for them to pass stool. This happens because certain nerve cells that help the bowel function properly are missing, leading to severe constipation, swelling, and blockages. In most cases, surgery is needed to remove the affected part of the intestine.

Recent studies, including research from Haereticus Environmental Laboratory, suggest that a common chemical in sunscreen called oxybenzone may increase the risk of Hirschsprung’s disease. Scientists have found high levels of oxybenzone in the urine of pregnant women whose babies were later diagnosed with the condition, meaning the chemical can enter the mother’s bloodstream and reach the baby during pregnancy.

“A pregnant woman who follows the instructions for the recommended use of sunscreen products containing 6% oxybenzone (two 1-ounce application of sunscreen) could have concentrations of oxybenzone and fetal blood levels reach as high as 3,800 part per billion in the woman, and 384 parts per billion in the fetus. These concentrations of oxybenzone can potentially cause these toxic cellular changes, and give rise to Hirschsprung’s Disease.”

Joe Dinardo, researcher from Heareticus Laboratory

Because oxybenzone stays in the body for weeks, experts recommend that pregnant women—or even those trying to conceive—avoid chemical sunscreens.

Which ingredients should pregnant women avoid?

“[…] Fetal development is an incredibly sensitive process that can be altered with the introduction of endocrine disrupting chemicals like oxybenzone. […] especially pregnant women and mothers should avoid all products with oxybenzone, and should instead seek out natural, organic skincare that does not rely on chemicals like these.[…]”

Lana Adler, environmental health educator

During pregnancy, women should be cautious about several chemical UV-filters and additional endocrine-disrupting chemicals that are commonly found in skincare and sunscreens.

Chemical UV-Filter to avoid:

Oxybenzone – Linked to hormone disruption and detected in amniotic fluid, breast milk, and fetal blood.
Octinoxate (Ethylhexyl Methoxycinnamate) – Can mimic estrogen and potentially interfere with pregnancy hormones.
Avobenzone – May degrade in sunlight and form harmful byproducts.
Homosalate – Shown to accumulate in the body and disrupt hormone regulation.
Octocrylene – Can break down into benzophenone, a potential carcinogen and endocrine disruptor.

Additional ingredients to avoid:

Retinoids (Retinol, Retinyl Palmitate, Retinoic Acid) – Excessive vitamin A intake has been linked to birth defects.
Parabens (Methylparaben, Propylparaben, Butylparaben, etc.) – Can mimic estrogen and may impact fetal development.
Phthalates – Common in synthetic fragrances, these chemicals can disrupt reproductive hormones.
Formaldehyde & Formaldehyde-Releasing Preservatives – Found in some skincare products and linked to toxicity concerns.
Hydroquinone – A skin-lightening agent that absorbs into the body at high rates.
Toluene – Found in nail polish and associated with nervous system toxicity.

How to choose a pregnancy safe sunscreen

Experts continuously recommend using natural and organic sunscreens during pregnancy that do not rely on chemical UV-filters.

⇒ choose a mineral sunscreen which sits on top of the skin rather than being absorbed into the skin and bloodstream

⇒ choose broad spectrum protection – sunscreens with non-nano zinc oxide provide excellent UVA & UVB protection without breaking down in the sun

⇒ choose a mineral sunscreen with organic ingredients that is gentle on your skin to be less likely to cause irritations

When choosing a sunscreen, be sure to always check the ingredient list at the back of the packaging. We know that chemical names can be overwhelming and half the time many people do not even know what the listed terms are supposed to mean. This is where apps like Yuka and INCI Beauty come in handy.

⇒ Yuka allows you to scan product barcodes and immediately see an ingredient safety rating, helping you to avoid potentially harmful or hormone disrupting components.

⇒ INCI Beauty provides detailed insights into each ingredient and rates them based on their toxicity, allergens, and environmental impact

Are Suntribe sunscreens pregnancy safe?

Yes! Suntribe sunscreens are pregnancy-safe and formulated with 100% natural and organic ingredients that have been proven to be safe for both mother and baby. Instead of using chemical UV-filters, we only use Non-Nano Zinc Oxide as the active UV-filter.

Here is why you can trust our sunscreens during pregnancy:

✔️ Non-Nano Zinc Oxide – According to the latest state of research the safest choice for both humans and the environment

✔️ No chemical UV-filter – Suntribe’s formulas pose no risk of hormone disruption

✔️Gentle, natural ingredients – Made with organic oils, butters, waxes, minerals, and vitamins, containing no synthetic additives or preservatives

✔️ Instant protection – Zinc Oxide as the mineral UV-filter creates a protective barrier on top of the skin from the first moment of application

The bottom line

Staying safe in the sun during pregnancy is just as important for your baby as it is for you. While protecting your skin from UV damage, hyperpigmentation, and premature aging is essential, not all sunscreens are equally safe to use. Many chemical sunscreens contain UV filters like oxybenzone and octinoxate, which have been found in amniotic fluid, breast milk, and fetal blood – raising concerns about their impact on hormone balance and fetal development.

The good news? You don’t have to choose between effective sun protection and safety. Mineral sunscreens with Non-Nano Zinc Oxide offer broad-spectrum UVA & UVB protection, sit on top of the skin instead of being absorbed, and are free from harmful chemicals. When choosing a sunscreen, always check the ingredients list – and if you’re unsure, tools like Yuka and INCI Beauty can help you make informed choices.

At Suntribe, we believe in keeping things simple, safe and natural – so you can enjoy the sun without worrying about hidden chemicals.

Skin Cancer: The most common—and preventable—cancer

By Karl Roos - March 20, 2025

The truth about skin cancer

Skin cancer is the most common cancer in the world—but also one of the most preventable. Despite its prevalence, many people still underestimate the risks associated with excessive sun exposure and the importance of daily sun protection. Understanding what skin cancer is, how it develops, and how to protect yourself can significantly reduce your risk. Let’s dive into this slightly uncomfortable topic and use scientific data to better understand how to enjoy the great outdoors while minimizing the risks.

What is skin cancer ?

Skin cancer occurs when skin cells grow uncontrollably due to DNA damage, primarily caused by exposure to ultraviolet (UV) radiation. This damage triggers mutations that lead to abnormal cell growth, resulting in cancerous tumors. It can affect anyone, regardless of age, gender, or ethnicity, but those with lighter skin tones and frequent sun exposure are at higher risk.

The three main types of skin cancer

There are several types of skin cancer, but the three most common are:

Basal Cell Carcinoma (BCC): This is the most common form and appears as a waxy bump or a persistent sore. It grows slowly and rarely spreads but can cause significant damage if left untreated.
Squamous Cell Carcinoma (SCC): More aggressive than BCC, SCC can develop into larger growths and spread to deeper tissues if not treated promptly.
Melanoma: The deadliest form of skin cancer, melanoma often appears as an irregularly shaped or colored mole and can spread rapidly to other organs if not caught early.

Understanding these different types can help you identify warning signs and seek medical attention if needed.

How is skin cancer connected to sunbrun?

Sunburn is more than just a temporary discomfort; it is a clear sign of skin damage that can have long-term consequences. When exposed to UV radiation—whether from the sun or artificial sources like tanning beds—your skin cells suffer DNA damage. Over time, this accumulated damage increases the risk of developing skin cancer.

Some important facts about sunburn and skin cancer include:

One blistering sunburn during childhood or adolescence doubles the risk of melanoma later in life.
UV damage is cumulative, meaning that every sunburn adds to the overall risk.
A “base tan” does not protect your skin; in fact, any tan is a sign of skin cell injury.

Although the redness of a sunburn fades, the genetic mutations caused by UV exposure remain, making prevention the best approach to reducing risk. It’s important to remember that when it comes to sun exposure – looks are deceiving. Even though tanned skin might appear healthy or attractive, this is not the case. UV exposure is necessary for human health and vitamin D synthesis, but the amount of UV exposure that causes tanning is too much for the skin. So it’s important to remember that this is not a question of exposing or not exposing yourself to the sun – but rather to do it in moderation and with an understanding of the factors that make sun exposure more or less harmful.

As an example, with sunscreen and outside the peak hours of sun exposure, the skin can handle much more time in the sun without getting damaged, as compared to without sunscreen and in peak hours.

Who is most at risk?

While anyone can develop skin cancer, some individuals are at a higher risk due to specific factors. These include:

⇒ Fair or sensitive skin – People with less melanin have lower natural UV protection.

⇒ Frequent sunburns – A history of sunburns increases the likelihood of skin damage.

⇒ Tanning bed use – Artificial UV exposure significantly raises the risk.

⇒ Family history of skin cancer – Genetic predisposition can play a role.

⇒ Excessive sun exposure – Those who spend long hours outdoors without protection are more vulnerable.

Assessing Your Risk

If you’re unsure whether you’re at risk, ask yourself:

Do I have fair or sensitive skin?
Have I had multiple sunburns in my life?
Do I frequently spend time in the sun without protection?
Have I used tanning beds in the past?
Does skin cancer run in my family?

If you answered “yes” to multiple questions, you may need to take extra precautions and schedule regular skin checks.

How to protect your skin

Protecting your skin from harmful UV radiation is essential in preventing skin cancer. The best strategies include:

⇒ Monitoring changes in your skin. Keep an eye out for new moles, spots, or patches that change in size, shape, or color. Sores that don’t heal or growths that appear suddenly should also be checked by a dermatologist.

⇒ Using broad-spectrum sunscreen (SPF 30+). Apply generously and reapply every two hours, especially when swimming or sweating.

⇒ Wearing protective clothing. Hats, sunglasses, and UPF-rated fabrics provide extra protection.

⇒ Seeking shade during peak sun hours (10 AM – 4 PM). Limiting sun exposure during these hours significantly reduces risk.

⇒ Being mindful on cloudy days. UV rays penetrate clouds, meaning you can still get sun damage even when the sun isn’t shining directly.

⇒ Avoiding tanning beds. The high levels of UV radiation from tanning beds increase skin cancer risk dramatically.

By incorporating these habits into your daily routine, you can lower your risk of developing skin cancer while maintaining healthy skin.

Choose the right sunscreen

Not all sunscreens offer the same level of protection. Here are some key points to consider when selecting one:

✔ Mineral sunscreens (with zinc oxide or titanium dioxide) provide broad-spectrum protection and are safer for both your skin and the environment. Mineral sunscreens are also effective from the moment of application, which also makes them more reliable in many real world scenarios.

𝗫 Chemical sunscreens can be effective but may contain ingredients with potential health risks. Chemical sunscreens also require some time after application before they are effective, which in some real world situations is less than ideal.

✔ Water-resistant formulas are ideal for prolonged outdoor activities or any type of sport activity.

What to do if you get a sunburn?

Despite best efforts, sunburns can still happen. If you do get burned, follow these steps for a faster recovery:

Cool your skin with cold compresses or aloe vera gel. After sun gels and balms work great for this as well.
Stay hydrated to support your body’s healing process.
Avoid peeling or popping blisters to prevent infection and scarring.
Moisturize regularly to keep skin hydrated and reduce discomfort.

While these steps can help alleviate symptoms, preventing sunburns in the first place is the most effective way to protect your skin.

The bottom line

Skin cancer is a serious but largely preventable disease. With simple, proactive measures, you can drastically reduce your risk and protect your skin for years to come. Daily sun protection, early detection, and smart habits make all the difference.

There’s no such thing as a safe tan—your skin’s health should always come first. By making sun protection a daily habit, you ensure that your skin remains healthy and resilient for a lifetime.

Does SPF impact Vitamin D intake?

Does SPF impact Vitamin D intake?

Does SPF impact Vitamin D intake?

By Hanna Oltmanns - January 20, 2025

Concerns about sunscreen hindering Vitamin D production are widespread, but what does the science actually say?

Let’s unpack the facts to put your worries at ease.

Why do you need Vitamin D?

Vitamin D is an essential nutrient that plays a crucial role in maintaining a healthy body. It helps regulate calcium and phosphate levels, which are vital for building and maintaining strong bones and teeth. Without adequate Vitamin D, the body struggles to absorb enough calcium, increasing the risk of conditions like osteoporosis and rickets.

But that is not all. Research increasingly suggests that Vitamin D may also support the immune system, reduce inflammation, and play a role in protecting against certain chronic diseases. While science is still evolving, what is clear is that maintaining healthy levels of Vitamin D is essential for overall well-being.

How is Vitamin D produced?

Vitamin D production is triggered when UVB rays from the sun interact with your skin. UVB rays stimulate a compound in the skin, called 7-DHC, to produce Vitamin D3. This process takes place in the outer layers of your skin and is influenced by factors like the intensity of sunlight, the amount of skin exposed, and your skin tone.

SPF is designed to block UVB rays, protecting your skin from sunburn and reducing the risk of damage such as premature aging and skin cancer. But does this protection come at the cost of your body’s ability to produce Vitamin D? It’s a common concern that sunscreen might interfere with Vitamin D production, as UVB rays are essential for triggering this process in the skin. However, is this worry really justified? Let’s take a closer look.

What happens to Vitamin D intake when you wear sunscreen?

The good news is: while SPF does reduce UVB penetration, no sunscreen is 100% effective. Research shows that typical sunscreen use does not significantly impact Vitamin D levels. For example, SPF 50 blocks 98% of UVB rays, leaving 2% of UVB rays that still reach your skin. That might sound little, but it is more than enough for your body to produce sufficient Vitamin D – even if you apply sunscreen exactly as instructed (which, let’s face it, most of us don’t).

Interestingly, your body has a natural limit for how much Vitamin D it can produce from sunlight. After a certain point, further sun exposure won’t increase Vitamin D production, but can lead to harmful effects like DNA damage and sunburn.

How much UVB do you really need?

The reality is, your body does not need much UVB exposure to produce Vitamin D. Even small, incidental amounts of sunlight during your daily activities are usually enough to keep your levels healthy. Studies show that for example in Spain during spring and summer, 10-20 minutes of midday sun exposure on 25% of the body, such as face, arms, and legs, are sufficient to produce adequate Vitamin D.

Generally speaking, the amount of UVB exposure needed daily for Vitamin D production depends on the skin tone, with light skin requiring 5-15 minutes and darker skin needing about 30 minutes to a few hours. Certain factors, such as geographical location, season, time of day, and the skin area exposed also play an important role. While midday sun and larger exposed areas are the most effective for Vitamin D production, even other times of the day and less skin exposure can be more than enough to keep your Vitamin D level steady.

However, your body naturally limits how much Vitamin D it can produce, so spending more time in the sun won’t boost your levels—it will only increase your chances of sunburn and skin damage. So, more sun exposure doesn’t mean more benefits—just more harm.

Why choose sun protection?

Without sun protection, UV rays can cause more harm than good. Excessive UV exposure is directly linked to skin cancer, premature aging and DNA damage. While it is true that UVB helps you to produce Vitamin D, the same rays are also responsible for sunburn and skin cell mutations.

Dermatologists agree: the risk of unprotected sun exposure outweighs any perceived Vitamin D benefits. The good news is that you can get all the Vitamin D you need, without putting your skin at risk.

How to get the Vitamin D you need?

Getting enough Vitamin D is easier than you might think and you do not have to rely on the sun alone.

⇒ SUNLIGHT

Getting a little UVB exposure during your daily activities helps your body naturally produce Vitamin D. In the summer, just a few minutes in the sun on your face, arms, or legs, 2-3 times a week, is usually enough.

Keep in mind that longer sun exposure won’t increase your Vitamin D levels, and even with sunscreen, your body still gets enough UVB rays to produce what it needs.

⇒ FOOD

Certain foods, such as salmon, mackerel, and tuna, are naturally high in Vitamin D, while egg yolks provide a smaller amount.

⇒ SUPPLEMENTS

Taking Vitamin D supplements is a safe and reliable way to keep your levels healthy. Consider asking your doctor for a simple blood test to check your Vitamin D levels, and then discuss the right supplement dosage based on your results.

The bottom line

The idea that sunscreen prevents your body from producing Vitamin D is a myth. Even when applied correctly, SPF protects your skin from harmful UV rays while still letting your body produce the Vitamin D it needs. Pair this with a nutritious diet and supplements if necessary, and you’ll get all the Vitamin D your body requires—without compromising your skin’s health.

So there you have it: keep slapping on the SPF, knowing that you are protecting your skin and staying healthy at the same time.

Make a safe choice - Suntribe scores on INCI Beauty & Yuka

By Hanna Oltmanns - September 17, 2024

Beauty apps like INCI Beauty and Yuka provide a simple and effective way to evaluate the safety and quality of cosmetic products. They guide you through the complex regulations of the beauty industry, helping you make informed decisions when selecting products that are both effective and safe for your health and well-being.

INCI Beauty and Yuka are among the leading apps in Europe for assessing the safety and quality of cosmetic products, though they are not the only ones. Apps such as Think Dirty and EWG Skin Deep are also highly regarded. In this article, however, we will focus exclusively on INCI Beauty and Yuka to provide a more profound understanding of their functionalities and our reasons for collaborating with them.

Why should you care about beauty app ratings?

Making good choices as a consumer in the beauty industry can be overwhelmingly complicated if you do not hold a degree in chemistry. Evaluating ingredient lists, safety standards, the newest research on certain ingredients and a product’s effectiveness can be difficult to navigate if you are not an expert in the field.

This is where INCI Beauty and Yuka come in to simplify your life and help you choose the right products. Both apps enable you to make informed and conscious consumer choices while helping us at Suntribe visualize the safety of our products and the components we use. At Suntribe, we are committed to using 100% natural ingredients, and these independent safety ratings support and verify the effectiveness and non-toxicity of our sunscreens.

How do beauty apps work?

INCI Beauty and Yuka are designed to simplify the process of understanding cosmetic ingredients. By scanning the barcode of a product, both apps provide you with an instant assessment of its safety and effectiveness based on the ingredient list.

On INCI Beauty, each product receives an overall score ranging from 0 to 20. Ingredients are identified using a colour-coded system of flowers, ranging from green to red. Essentially, the more red in the flower, the more problematic the ingredient is considered, and conversely, more green indicates a safer ingredient.

Yuka’s algorithm evaluates cosmetic products with a score out of 100, reflecting the safety and health impacts of the ingredients. Each ingredient is assigned a score ranging from green to red, which is then summarized in an overall score of the product itself.

What do the colours mean?

A product’s rating is being visualized by a colour system. While Yuka rates products out of 100 with a focus on overall health impact and colours ranking from Risk-free to Hazardous, INCI Beauty scores out of 20, emphasizing both a product’s ingredient safety and environmental impact. Here, the colour system reveals penalties of different degrees of intensity assigned to ingredients and used in the calculation of product ratings.

Both apps are constantly evolving, and ingredients may switch from one colour to another as the knowledge and research of different components changes.

For more information on the cosmetic analysis on both apps, check out their websites:

What does a lion have to do with cosmetic safety ratings?

When it comes to cosmetics, understanding the difference between “danger” and “risk” is key. Picture a lion: it’s naturally dangerous, but the risk it poses changes based on the situation. A zookeeper entering the lion’s cage is at much greater risk than a visitor safely watching from behind glass. This idea helps explain how beauty apps rate cosmetic products. INCI Beauty uses coloured flowers to show how “dangerous” an ingredient might be, but the actual risk to you depends on things like how the product is used, the amount of the ingredient, and who’s using it.

Yuka takes this a step further by looking at both the danger and the overall health impact of the ingredients, giving you a fuller picture of the risks. Both apps work to ensure their ratings reflect not just the potential dangers, but the actual risks you might face when using these products.

How are the scores being calculated?

When INCI Beauty and Yuka calculate scores for cosmetic products, they take an in-depth and balanced approach. Instead of just labelling ingredients as “good” or “bad,” these apps use a system that considers the potential risks of each ingredient without being overly harsh. For example, if an ingredient is suspected of being an endocrine disruptor, the product doesn’t automatically get a terrible score. Instead, it’s penalized in a way that reflects the level of concern, not just a blanket judgment.

Both INCI Beauty and Yuka also consider how many potentially risky ingredients are in a product, how much of each ingredient is used, and the “cocktail effect” — the idea that multiple ingredients can have a bigger impact together than alone. When multiple ingredients are combined, they can interact with each other and have a stronger or different impact than when they are used alone. The beauty apps take this into account, recognizing that the combined effect of several ingredients might increase the overall risk.

Plus, factors like whether a product has organic certifications or where certain ingredients are listed can add bonuses or penalties to the final score. This method ensures that the ratings you see are fair and give a realistic picture of the product’s safety.

What scores do Suntribe products have?

On Yuka, Suntribe products have ratings ranging from 68 to 100. Our natural cosmetic products have a safety rating of 100 / 100. When it comes to our sunscreens, this rating ranges from 83 for our Active SPF 50 sunscreen to 93 for our SPF 30 sunscreens.

This change in scores is related to recent updates of the danger level of Zinc Oxide, which we are using as a mineral UV filter. The way Zinc Oxide is classified is why our safety ratings have changed in the past year, yet our products have remained exactly the same.

Since the beginning of 2024, both INCI Beauty and Yuka no longer differentiate between Nano and Non-Nano Zinc Oxide, grouping them as one and therefore labelling all products containing Zinc Oxide as if it was used in its nano form. This can be quite misleading to consumers, as it is important to know that they are not the same.

In our blog article “The Ultimate Guide to Non-Nano Uncoated Zinc Oxide,” we explain the difference between Zinc Oxide in Nano and Non-Nano form in detail and why we at Suntribe use Non-Nano Zinc Oxide only. The main difference is that nanoparticles can be absorbed into the bloodstream and have been traced in human urine. They therefore bear a much greater risk than non-nano particles, which do not penetrate the skin and hold no danger of entering into the body’s systems. Currently, Non-Nano Zinc Oxide has been shown to be the safest option of UV filter to use for human health and marine life.

On INCI Beauty, Suntribe products rate from a minimum of 16.3 all the way up to 20 and our whole range has been labelled with a green badge in the overall rating, the highest possible rating.

Making informed choices when deciding which products you allow on your skin is key to wholesome well-being. Thanks to advanced technology and beauty apps, this is now easier than ever, and should you still be unsure whether a specific product meets your needs and standards, you can always get in touch with the brand and ask.

Should you ever have any questions about our products, their ingredients, safety, and beauty app ratings, you are welcome to reach out anytime! Simply contact us at contact@suntribesunscreen.com.

The Dangers of Synthetic fragrances

By Hanna Oltmanns - April 3, 2023

The Environmental Working Group (EWG) conducted a study and found that, on average, fragrance products contain 14 hidden chemicals that aren’t listed on the label. These chemicals can include substances linked to hormone disruption, allergic reactions, and reproductive toxicity, which raises serious concerns about the safety of the products we use every day. Despite this, the fragrance industry is not required to disclose these hidden ingredients, leaving consumers unaware of what they are truly exposed to.

Scent, however, is more than just a label – it’s a powerful trigger that can evoke deep emotions and transport us to different moments in our lives. A particular fragrance might instantly bring you back to a cherished childhood memory, like the comforting smell of your grandma’s kitchen or a perfume that reminds you of a loved one. This unique ability of scent makes it all the more important to be aware of the ingredients in the fragrances we choose.

What are synthetic fragrances?

Synthetic fragrances are chemically manufactured scents found in a wide range of products, from cosmetics to household cleaners. According to their official definition, they are a blend of chemicals used to create specific scents. These fragrances are everywhere, including personal care products, laundry detergents, candles, and even food.

The risks of synthetic fragrances

Synthetic fragrances can contain over 3,000 different chemicals, many of which are harmful. A study by the Environmental Working Group (EWG) found that synthetic fragrances often contain hidden chemicals, some of which are linked to serious health issues.

1. Allergic reaction

Fragrances are one of the top five allergens globally, causing reactions such as headaches, migraines, and skin irritation. More than 50% of shampoos, conditioners, and styling products list “fragrance” as an ingredient, but it doesn’t improve the product’s performance—it simply adds an artificial scent.

2. Endocrine disruption

Many chemicals in synthetic fragrances, including phthalates and synthetic musks, are known to disrupt the endocrine system. These chemicals can mimic human hormones, leading to abnormal cell reproduction and long-term health risks like cancer, infertility, and other hormone-related issues.

3. Cancer-causing

Of the thousands of chemicals used in synthetic fragrances, at least seven are known to be carcinogenic, with many banned in the EU but still present in products sold in the U.S. One such chemical, benzene derivatives, is linked to leukemia and other cancers.

4. Respiratory and neurological issues

Regular exposure to synthetic fragrances has been linked to asthma, difficulty breathing, and neurological symptoms such as brain fog, dizziness, and headaches. This is particularly concerning for individuals with pre-existing respiratory conditions.

The beauty industry's loophole

One of the biggest concerns with synthetic fragrances in beauty products is the lack of transparency. Manufacturers are allowed to label these chemical blends simply as “fragrance” or “perfume” without disclosing the individual ingredients, thanks to a legal loophole protecting “trade secrets.” This allows companies to hide dozens or even hundreds of harmful chemicals behind a single term.

“A single synthetic fragrance can contain up to 200 different chemicals, all listed under the one word “fragrance”.

How to avoid synthetic fragrances

Here are some tips to protect yourself from the harmful effects of synthetic fragrances:

1. Read ingredient labels carefully

Always check product labels for terms like “fragrance” or “perfume.” These are red flags indicating the presence of undisclosed chemicals. Opt for products that explicitly state they use essential oils or natural plant extracts.

2. Choose trusted brands

Smaller, eco-conscious brands are often more transparent about their ingredients. Look for brands that are committed to using 100% natural ingredients, prioritizing natural or organic fragrances, and being open about all their product components.

3. Switch to essential oils

Opt for products scented with essential oils, which are derived from natural sources like plants and can offer therapeutic benefits.

4. Beware of “unscented” claims

Some “unscented” products may still contain chemicals to mask other odors, so always check the ingredient list.

5. Use ingredient verification apps

Apps like INCI Beauty, Think Dirty and Yuka can help you verify the safety of ingredients in your personal care products. These apps scan product barcodes and provide detailed information about each ingredient.

Essential Oils vs. Synthetic Fragrances

Essential oils, while often a safer alternative, come with their own considerations. They are derived from natural plant sources, such as flowers, leaves, and bark, and are generally free from harmful chemicals. However, producing essential oils is labor-intensive and costly. For example, creating just 1 kg of rose essential oil requires up to 10,000 kg of rose petals. This makes essential oils more expensive, but they offer unique benefits that synthetic fragrances simply can’t replicate.

The Environmental Impact

Synthetic fragrances are often created from petrochemicals, which are derived from fossil fuels. This not only contributes to environmental pollution but also results in products that take much longer to break down in the ecosystem.

Essential oils, on the other hand, are biodegradable and have a much lower environmental footprint and are therefore a more sustainable option.

Suntribe’s Commitment to 100% Natural Ingredients

At Suntribe, we never use synthetic fragrances in our products. Our formulas are entirely natural, and the subtle scents come from organic butters, waxes, or essential oils. For instance, the vanilla scent in our Baby & Kids SPF 30 Sunscreen comes directly from the fruit of the vanilla planifolia orchid—not a synthetic imitation.

Key Takeaways

Synthetic fragrances can contain harmful chemicals linked to allergies, hormone disruption, and even cancer.
Be proactive by reading labels and choosing products that use essential oils or plant-based aromas.
Use apps like INCI Beauty, Think Dirty or Yuka to identify potentially harmful ingredients in your personal care products.
Opt for trusted and smaller brands that prioritize transparency and natural ingredients.

By making more informed choices, you can protect your health and reduce your exposure to toxic chemicals. Remeber, every small change you make in your daily routine can have a significant impact on your long-term well-being.

What Are PFAS and How To Avoid Them

What are PFAS and how to avoid them

By Hanna Oltmanns - June 4, 2024

Sunscreen is essential for sun protection, but did you know that the type of sunscreen you use could impact your health and persist in the environment for many years?

Per- and polyfluoroalkyl substances (PFAS), also known as “forever chemicals,” have been making headlines due to their potential harm to human health and the planet. These man-made chemicals have been in use since the 1940s and are made of carbon and fluorine molecules bonded together. This strong bond makes them resistant to breakdown, allowing PFAS to be found in a wide range of products, including non-stick cookware, water-repellent clothing, and some cosmetics

PFAS have been linked to serious health effects, including cancer, high cholesterol, and birth defects. Unfortunately, these chemicals are found in a wide range of consumer products, including some sunscreens. According to a study conducted by the Nordic Council of Ministers 12,000 people die every year due to PFAS in the European Union alone.

The good news are: in January 2023, Germany, Sweden, Denmark, Norway and the Netherlands submitted a landmark proposal to restrict the use of 10,000 PFAS chemicals under the REACH regulation. The European Chemicals Agency (ECHA) is currently investigating the request.

Why should you avoid exposure to PFAS?

“PFAS have been linked to serious health effects, including cancer, high cholesterol, and birth defects.”

PFAS are almost indestructible, which means they persist in the environment and pose an ongoing problem. They have been used in various products worldwide and are believed to cause various health problems such as impaired fertility, liver damage, cancer, developmental issues, and immune system disruption.

Scientists are concerned that PFAS can build up in peoples’s bodies that are exposed to these chemicals over long periods of time. Since they don’t degrade easily, PFAS can accumulate in the food chain. The main way people are exposed to PFAS is through eating and drinking contaminated food and water.

One of the most concerning aspects of PFAS however is their persistence. They take more than a thousand years to break down and are not easy to get rid of. As a result, they can, potentially cause harmful long-term and dramatic health effects as already mentioned above in both humans and animals. This persistence also means that PFAS chemicals pose an issue that requires our immediate attention.

How to limit your exposure to pfas

There are several simple steps you can take to protect yourself and the environment from PFAS exposure:

1. Choose alternative products

Opt for stainless steel or cast iron cookware instead of non-stick cookware, and avoid products with water- or stain-resistant coatings.

2. Select PFAS-free Sunscreens

Choose sunscreens free of PFAS. Avoid compounds like “PAP” (polyfluoroalkyl phosphate esters) or “PTFE” (polytetrafluoroethylene). Selecting PFAS-free sunscreen benefits your health, the environment, and marine life. When you swim, your sunscreen can wash off and enter the water, potentially harming fish, coral, and other aquatic life. Studies show that PFAS can accumulate in fish and other animals, leading to harmful effects on their health and ecosystems.

3. Use certified PFAS-free products

Look for products certified as PFAS-free by third-party organizations like the Green Science Policy Institute or the Environmental Working Group. These organizations conduct independent testing to ensure products do not contain PFAS or other harmful chemicals.

4. Filter your drinking water

PFAS can enter drinking water through sewage, industrial discharge, firefighting foam, and other sources. If you’re concerned about PFAS in your water, have it tested by a professional laboratory. Use a certified filter designed to remove PFAS.

By taking these simple steps, you can reduce your exposure to PFAS and protect your health and the environment. Remember, small changes can have a big impact. Choose wisely when it comes to the products you use, the cosmetics you put on, and the food you eat. By making conscious choices, we can all contribute to a healthier, more sustainable future.

“PFAS are almost indestructible which means they persist in the environment and pose an ongoing problem.”

Suntribe's commitment to PFAS-free sunscreens

All Suntribe sunscreens are free from harmful chemicals, including PFAS. Our natural sunscreens are formulated with only clean ingredients, using non-nano mineral UV-filters for broad-spectrum protection against UVA and UVB rays. We use organic waxes for natural water resistance and package our sunscreens sustainably, allowing you to protect your skin and the environment simultaneously.

Another way to limit your exposure to PFAS is to choose products that are certified as PFAS-free by third-party organizations, such as the Green Science Policy Institute or the Environmental Working Group. These organizations conduct independent testing on consumer products to ensure that they do not contain PFAS or other harmful chemicals.

“Reef-Safe” Definition and What it Actually Means

Suntribe — Fri, 31 May 2024 09:32:17 +0000

“Reef-Safe” Definition and what it actually means

By Hanna Oltmanns - May 31, 2024

"At Suntribe being transparent about our products, their ingredient lists, their safety, and their certifications is one of the core values of our brand. "

There has been a lot of talk about reef-safe sunscreens. Many brands in the sunscreen industry have used the term “Reef Safe” as a buzzword to sell products and give their sun care a green label to boost their sales. These issues have been made known by the media for the last two years extensively, and it made it very clear that “Reef Safe” is a term that is simply not defined enough.

Yet, it ranks among the top five claims with the highest increase in average monthly search volume, meaning it is a key phrase to discuss in the sunscreen industry.

At Suntribe being transparent about our products, their ingredient lists, their safety, and their certifications is one of the core values of our brand. We believe this is the only way that we can offer effective sunscreen products that you can trust. For this reason, we decided to write a post about how we at Suntribe define “Reef Safe” and what it means when you read it on our sunscreen packaging-

How is “Reef-Safe” generally defined?

Google defines “Reef-Safe” sunscreens as sunscreens that do not contain chemical UV filters such as Oxybenzone and Octinoxate. This definition was birthed when Hawaii started to ban chemical UV filters from their reefs, after research has shown that these two chemical UV filters in particular have caused coral bleaching and have been revealed as endorphin disruptors.

Renowned scientists such as Craig Downs, PhD, found their research results highly alarming and took action by getting their government to ban the use of sunscreens containing these chemicals.

“The number one ingredient that we would see was Oxybenzone. We took water samples and then we measured the amount of Oxybenzone in the water, and we were stunned by how high the concentrations were.”

— Craig Downs, PhD

After Hawaii took action, places like the US Virgin Islands, Bonaire, Palau, and Thailand followed suit in banning toxic sunscreen chemicals to protect their reefs, corals and aquatic life.

However, not including chemical UV filters such as Oxybenzone and Octinoxate in sunscreens is only the tip of the iceberg and far from enough when it comes to producing “Reef-Safe” sunscreens.

Since the sunscreen ban in Hawaii, research has revealed several additional chemical active (such as UV filters) and inactive sunscreen ingredients (for example preservatives) to be toxic to both humans and the environment.

As research evolved, sunscreen brands labelling their products as “Reef Safe” needed to withdraw from the term “Reef Safe” in their marketing communication.

Brands like Bondi Sands, Banana Boat and Edgewell Personal Care, are among companies that have faced lawsuits for reef-related claims as continued research revealed they still used harmful ingredients in their products affecting reefs.

The simple avoidance of Oxybenzone and Octinoxate is clearly not enough to create a “Reef-Safe” product!

What does current research say about the safety of UV-filters for coral reefs?

There has been ongoing research to assess the safety and effectiveness of various chemical UV filters. This includes studying their potential to cause skin irritations, allergic reactions, hormone disruption, or environmental harm.

Research has shown that 63% of ingredients in the most popular sunscreens in Europe are classified as dangerous for human health and/or the environment.

UV filters such as Oxybenzone, Octinoxate and Octocrylene have been confirmed as toxic for corals.

Active ingredients such as Homosalate, Octisalate, and Octocrylene have been linked to impairing the growth of marine wildlife, causing birth defects in humans and fish, and accumulating in the brain and liver of zebrafish.

Craig Downs, PhD, who we already mentioned above, is a renowned scientist and Executive Director at the Haereticus Environmental Laboratory. He and his team have been researching sunscreen ingredients for almost two decades and strongly advocated the chemical sunscreen ban that Hawaii implemented in 2021.

They compiled a list of ingredients that are known pollutants which everybody should be aware of and completely avoid. They call it the HEL list. It started off as scientific literature about the dangers of Oxybenzone and Octocrylene. Now the list includes 13 common sunscreen ingredients based on the latest research. As the science on sunscreen chemicals increases, so does the list.

We at Suntribe formulate all our products based on the latest state of research and in close reference to marine biologists, such as Craig Downs, PhD.

As research is evolving, so do our sunscreens, and as scientific results adjust, so do our products.

“Reef-Safe” is more than a green ingredient list!

When we talk about “Reef-Safe” sunscreen, we need to talk about more than just the ingredient list at the back of the tube. “Reef Safe” means more than only a “green” ingredient list.

A product can only be truly “Reef-Safe” if the packaging, sourcing, and manufacturing are all done with sustainability in mind. Reasons for poor coral health and endangered marine life are multifaceted. Too often, customers are misled with words that are a simplification of concepts that are not simple.

In 2019, Craig Downs told Hawaii Public Radio: “Sunscreen pollution is about one of 100 to 1000 cuts a coral reef can experience, and it’s really location dependent.” Unrelated to sunscreen ingredients, he highlighted excessive pollution and agricultural run-off as two significant threats to Hawaii’s coral reefs.

As we mentioned before, transparency is the way we do business at Suntribe.

“With transparency comes confidence and safety. At Suntribe we know we can trust our products, and we’d like to show you why you can trust our products too.”

— Julia, Suntribe Co-Founder & Head of Product Development

We want to make it easy for everyone to see the steps we take to develop and produce our sunscreens. From choosing our production facilities, to selecting and sourcing our ingredients, and developing our skin care. We consider the impact of our labels, packaging and printed material, of the shipping and logistics behind the scene as well as the transportation of our products to their consumers. We consider the impact of our sunscreens on nature from all aspects.

For us, the term “Reef Safe” is more than a buzzword!

How do we at Suntribe define “Reef-Safe” Sunscreen?

Whilst we understand that nothing is 100% reef safe, and that research is continuously revealing new potential threats to marine life, you can be sure that we formulate our products hand in hand with the latest scientific results.

The Suntribe definition of “Reef-Safe” is much stricter than the definition that other brands apply.

The general definition of the term “Reef-Safe” is a negative one, defining which ingredients a sunscreen should NOT contain to be “Reef-Safe”.

We chose to define our sunscreens by using a positive definition.

We define “Reef-Safe” by only using UV-filters with the highest safety rating for humans and nature.

At Suntribe, we use natural, mineral UV-filters without nanoparticles that have been shown to be the safest option that is currently available for marine life and human health and are recommended by marine scientists such as Craig Downs, PhD.
