Знаем, че автобронзант е по-добре от яростно пържене на слънце или от солариума, но това не го прави по дефиниция безопасно.

A last caution from The Skin Cancer Foundation: Don’t be misled when products sound like self-tanning lotions — “Tanning amplifiers,” “tan accelerators,” “tanning promoters,” “tanning enhancers,” and worst of all, “tanning pills.” Many of the products interact with the sun to create the tan, so they actually end up accentuating the damage done to the skin. The pills — which are commercially banned in the U.S. — are the worst. They contain the carotenoid chemical canthaxanthin (the same pigment found in carrots), and have been associated with hepatitis and urticaria, a condition that involves relentless itching and skin eruptions.

“Read the ingredients on the label of all these products carefully,” says Dr. Levy. “Unless their active ingredient is DHA, they’re not bona fide sunless tanners, and they could very well be harmful for your skin.”
