Much of the research supporting nutricosmetics is still industry-sponsored, according to Robert Blair, PhD, coeditor of Nutritional Cosmetics: Beauty from Within (William Andrew, 2009). But that doesn’t necessarily make it illegitimate. “All cosmetic manufacturers are required to substantiate the safety of and the claims they make about their products,” says Farah Ahmed, vice president and associate general counsel for the Personal Care Products Council. “Many companies will have peer-reviewed, published data publicly available and supplement it with their own data. The industry is working on increasing the level of transparency.” Ingredients such as collagen, lycopene, and omega-3s show promise for long-term beauty support.
