EltaMD broad-spectrum sunscreens provide safe, broad-spectrum ultraviolet (UV) protection. A broad-spectrum sunscreen helps prevent sunburn and if used as directed with other sun protection measures, decreases the risk of skin cancer and early skin aging caused by the sun. Ultraviolet, or UV rays, are part of the invisible energy that comes from the sun. UVA (aging) rays account for 95% of our sun exposure. They cause skin aging and contribute to skin cancer. UVA rays penetrate deeply into the skin layers, damaging collagen and cells which leads to wrinkling, hyperpigmentation and loss of elasticity. UVB (burning) rays mostly affect the outer layer of the skin. They cause sunburns and tanning that increase the risk of skin cancer and other disorders. The risk for skin cancer doubles in people who have had five or more sunburns. Skin Cancer Foundation (Nov. 2010)
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.
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.
