All EltaMD sunscreens are formulated with zinc oxide, a natural, mineral compound. Because zinc maintains its protective ability in the sun, it is more photostable than some chemical ingredients that may degrade. Zinc sunscreen blocks the widest spectrum of UVA and UVB rays, protecting skin against burning and the premature appearance of aging and risk of skin cancer. Zinc is safe for even the most sensitive skin types.
When wearing EltaMD sunscreens, the UVA and UVB rays reflect and scatter away from your skin, providing you protection from sunburn. EltaMD sunscreens help prevent sunburn and, if used as directed with other sun protection measures, decrease the risk of skin cancer and early skin aging caused by the sun.
