Zinc Oxide - 10% (Non-Nano)

ZIN

9/10

Concern level

High concern

Zinc oxide is an inorganic mineral UV filter and skin protectant used in sunscreens and barrier creams. In non-nano form, it sits on the skin surface and reflects/scatters UV radiation while also providing mild soothing and protective effects. At 10% it is a mid-range sunscreen level rather than a maximum-strength mineral filter.
