Zinc oxide is one of 17 active ingredients approved by the FDA for use in sunscreens. When you apply zinc oxide sunscreen the particles sit on the outermost layer of your skin, the stratum corneum, where they scatter and absorb ultraviolet radiation, protecting your living skin below. Zinc oxide is unique among sunscreen ingredients in that it is truly a broad spectrum blocker, protecting you from UVA, UVB and UVC.
