Question: Do collagen supplements really help for aging or wrinkled skin?
Answer: Adults lose about 1% of the collagen in their skin each year, which contributes to thinning and wrinkling in aging skin. This loss of collagen may be more evident at an earlier age in women, who have less collagen than men. Many collagen supplements, such as, NeoCell Derma Matrix Collagen Skin Complex, Life Extension Hair, Skin and Nails Rejuvenation Formula and Lindberg Skin Rejuvenator are promoted to improve the skin and some contain branded collagen ingredients such as VERISOL and BioCell Collagen which have been tested in studies. But can taking collagen supplements, in the form of capsules, tablets, or powders, actually increase the collagen in skin, or improve the skin's appearance? The evidence suggests that some products may have modest effects, but the evidence for other products is weak, as explained in the full answer >>
