Sun Day School: Skin Cancer Protection Tips

Double Up on Certain Spots

A shot glass's worth of sunscreen is enough to cover your whole body, but derms say you might want to add a second coat to your nose, lips, hands, and ears and the tops of your feet -- areas that tend to burn. "You won't be doubling the protection, but you may actually get the SPF listed on the bottle with two coats," says Ava Shamban, MD, a dermatologist in Beverly Hills. (Studies have shown that of those people who use sunblock, most apply only half the recommended amount.)
