Sunscreen: How it saves your skin
Sunscreen: How it saves your skin Sunscreens successfully prevent ultra-violet
energy from reaching the skin. Ultra-violet radiation can damage
DNA, cause wrinkling or photo-aging, and increase the risk of skin
cancer. Lotions vary in their degree of protection, called SPF, but
are designed to fight against UVA rays and the more harmful UVB
rays which show up in the form of sunburns and have many long-term,
damaging effects. 10 JUNE 1999
