EltaMD 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 agin 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.
