Mineral sunscreens are made with titanium dioxide and zinc oxide, usually in the form of nanoparticles. The FDA in 2021 proposed that both titanium dioxide and zinc oxide be classified as GRASE. Evidence suggests that few, if any, zinc or titanium particles penetrate the skin to reach living tissues.

Inorganic UV filters like titanium dioxide and zinc oxide – which are broadly considered safe – reflect and scatter UV radiation away from the skin.
Titanium dioxide (TiO2) is used in a variety of personal care products, including sunscreens, pressed powders, and loose powders, as a UV filter or whitening agent. In lotions and creams (dermal exposure), it is not a risk for adverse health effects.
