This year, new concerns have arisen about a form of vitamin A called retinyl palmitate, found in 41 percent of sunscreens. 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. 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.
