When we slather up with sun tan lotion, most of us bypass our lips. We coat our arms, our legs, our foreheads and noses with a suitable SPF -- but putting lotion on the lips is a non starter. And few people use a separate protective lip balm. In fact, a recent study out of Baylor University Medical Center at Dallas found that fewer than 25 percent of Americans protect their lips from the sun.
That's a big problem, because our lips are among the most vulnerable places on our bodies -- exceptionally prone to cancers and aging damage. According to dermatologist Christine Brown, "When skin cancer occurs on the lower lip, it has the potential to be much more aggressive and metastasize to surrounding lymph nodes."
