Zinc oxide is an active ingredient often found in physical sunscreens. ... It is also unique among sunscreen ingredients in that it effectively blocks all parts of the UV spectrum, including both ultraviolet A (UVA) and B (UVB) radiation. Zinc oxide is also very gentle on the skin and is less likely to cause irritation.
