Ingredient overview

What is Zinc Oxide?

Zinc oxide is an inorganic ultraviolet filter used in mineral sunscreens. Properly formulated zinc oxide can contribute broad-spectrum protection across UVB and UVA wavelengths, with performance influenced by particle size, coating, dispersion and the complete sunscreen system.

Modern micronized and nanoscale zinc oxide can reduce the visible white cast associated with older mineral sunscreens, but sunscreen efficacy cannot be predicted from the ingredient alone. The labeled SPF and UVA protection of the finished tested product matter far more than simply seeing zinc oxide on the INCI list.

How to use it

Use zinc-oxide sunscreen as the final morning skincare step and apply enough product to meet the labeled protection. Reapply according to exposure, sweating and product directions.

Pairing guidance

Routine compatibility

Zinc oxide can be formulated with titanium dioxide and approved organic UV filters. Compatibility and photostability are properties of the finished sunscreen system.

Formula context matters

Good to know

Do not judge sunscreen strength from zinc oxide percentage or presence alone. Rely on the tested SPF/UVA rating and proper application of the finished product.
