Cosmetics, diet, and the future.

Cosmetics and diet are two new areas of antiaging interest for the dermatologist. Novel delivery systems in the form of nanoparticles may allow the penetration of cosmetic actives into the skin creating new opportunities for active agent efficacy, but possibly also creating safety issues. The best method of introducing active agents into the body is through the oral route. New understandings of diet and how it affects aging are also becoming important in dermatology.
