Beauty chocolates and yogurts and drinks … oh my! Welcome to the magical world of nutricosmetics, a place where supplements and foods make your hair shiny, nails strong, and skin clear. Beauty isn’t only skin deep, claim the proponents of nutricosmetics—defined as foods, beverages, and supplements containing ingredients that support skin and body structure. The industry exploded in Japan in the 1940s and in Europe more than two decades ago (both still hold most of the market share) but is relatively new to the United States, where the science is young, the claims are bold, and many consumers are skeptical, research shows. Should you believe in the power of beauty-from-within? Yes—and no. Don’t expect immediate results. And do heed this advice for finding the most legitimate beauty-enhancing nutricosmetics.
