Jury Still Out On Whether Vitamin-Packed Skincare Products Treat Photoaging

March 1, 2010: 06:06 PM EST
Do vitamins really reduce the signs of sun-damaged skin? In a word, yes, but not necessarily when delivered in skincare products. According to a new U.S. study that examined the scientific literature, vitamins A, C, E and B3 prevent or reverse photoaging, the damage to skin caused by the ultraviolet radiation from the sun. But there is no solid evidence that these vitamins have any benefit when delivered in oral or topical skincare products. In skincare cosmeceuticals, vitamin C may actually dissolve when applied to the skin, one researcher noted. And no data support claims that vitamin C in skincare products improves skin wrinkling, discoloration and texture. “Consumers should understand … that skin care products with vitamins may not provide clinically meaningful improvement,” the researchers said.
