Some Lip Gloss May Promote Cancer

There's No Proof Yet But Beware Gloss With No SPF

Spring is here, legs have been reacquainted with the razor and women are buying lots of shimmery lip gloss on impulse.

But have you heard the buzz that cheap, fun, non-SPF gloss can possibly increase your skin cancer risk?

Here's the theory: Some dermatologists have said that the translucent sheen helps ultraviolet rays penetrate the already fragile skin of the lips -- thereby increasing your risk. These dermatologists may be on to something, according to some of the top experts in the field.

Dr. Jessica Fewkes, a face and neck skin cancer specialist at Harvard, draws a cautious analogy between wearing non-SPF (sun protection factor) lip gloss in the sun and using baby oil to promote tanning. "You might be able to infer that they both enhance UV exposure," she says.

Dr. Kevin Cooper, chairman of the dermatology department at Case Western Reserve in Cleveland, explains that any increased penetration of ultraviolet rays would be due to "enhanced optical passage" of the dangerous rays. But the increase, he qualifies, would be small.

Here's the catch: There are no large, targeted studies proving or disproving this theory, which makes Fewkes, Cooper and the American Cancer Society reluctant to draw fixed conclusions.

Dr. Len Lichtenfeld, the society's deputy chief medical officer, says that it seems "like just a theory."

"It's OK," he adds, " to have theories about how diseases are caused or influenced, but we have to see evidence. There should be an effort made to do large, population-based studies."
