Sunscreen Could Be Giving You Skin Cancer How to guard

"The FDA is investigating whether this compound may accelerate skin damage and elevate skin cancer risk when applied to skin exposed to sunlight. FDA data suggest that vitamin A may be photocarcinogenic, meaning that in the presence of the sun's ultraviolet rays, the compound and skin undergo complex biochemical changes resulting in cancer [...] In FDA's one-year study, tumors and lesions developed up to 21 percent sooner in lab animals coated in a vitamin A-laced cream (at a concentration of 0.5%) than animals treated with a vitamin-free cream. Both groups were exposed to the equivalent of just nine minutes of maximum intensity sunlight each day. [...] The evidence against vitamin A is far from conclusive, but as long as it is suspect, EWG recommends that consumers choose vitamin A-free sunscreens."
