Zinc oxide as gentle mineral sun protection

Physical UV protection

Reflects UV-A and UV-B – works the moment you put it on, no waiting for it to soak in.

Easy on sensitive skin

Classically well tolerated – the standard for babies, allergy-prone and sensitive skin.

Reef-friendly

Doesn't burden coral reefs or marine life – unlike chemical filters.

Zinc oxide is, for me, the only sun protection I'll put on kids without a second thought.

Mineral, non-nano, blocks the moment you put it on – with no hormonal load. It's in every one of our solid sunscreens with SPF50 and in the travel sizes too. Safe protection, no compromises.

The active in detail

Mineral UV filter without nanoparticles

Zinc oxide is a mineral UV filter that physically reflects UV-A and UV-B radiation. Unlike chemical filters, it doesn't penetrate the skin. We make a point of using non-nano quality (particles >100 nm) – which makes the filter especially gentle on skin and friendly to coral.

Science & care

How does zinc oxide work on the skin?

Three mechanisms that make zinc oxide the classic mineral sun protection.

01

Physical UV protection

Reflects UV-A and UV-B the moment you put it on – no soak-in time, no hormonal load.

02

Anti-inflammatory

Zinc oxide also has a soothing effect on irritated and inflamed skin – no surprise it's also in wound creams.

03

Stays on the skin

Unlike chemical filters, it doesn't get into the body – no hormonal concerns and suitable for pregnant women.

Terms

Glossary

Zinc oxide (Zinc Oxide)
Mineral UV filter that reflects UV rays.
Non-nano
Particles over 100 nm – cannot penetrate the skin, regarded as reef-friendly.
Mineral UV filter
Unlike chemical filters, it stays on the skin's surface.
UVA / UVB
Two ranges of UV radiation – zinc oxide protects against both (broad spectrum).
Reef-friendly
Reef-friendly – doesn't harm coral, required in many holiday regions.
Sun protection factor (SPF)
The factor by which the skin's own protection time is extended. SPF 50 = protected 50× longer.
