This naturally occurring compound provides a physical barrier that sits on the surface of the skin, scattering and reflecting ultraviolet (UV) rays before they can penetrate and damage skin cells. This mineral is classified as a physical or inorganic filter, meaning it creates a shield on top of the epidermis.
