Cover your mouth

We're talking about a lip balm with UV protection, not ruby red lipstick. Your lips (along with your eye area and upper chest) have some of the thinnest skin on your body, so they need extra shielding.
A survey by a member of the American Society for Dermatologic Surgery found that only 47 percent of respondents used lip protection containing UV blockers. That's bad news, because "when skin cancer originates from the lips, it's especially aggressive and has a higher risk of spreading," says Erin Welch, M.D., assistant professor of dermatology at the University of Texas Southwestern Medical Center.
Guard your smackers by stocking up on balms with sunscreen, like Softlips Lip Protectant/Sunscreen with SPF 20 ($4 for two tubes, drugstore.com).
