The number of skin care products containing vitamins has more than tripled since 1991. Vitamin A and its precursor, beta-carotene, are the primary prescription agent currently used for anti-aging purposes. Vitamins C and E, when applied topically, are thought to improve moisturization, reduce fine lines and wrinkles, and protect from the sun. Vitamin B5 (panthenol) increases the water content of the hair shaft, thereby increasing manageability. Now skin scientists have begun adding niacinamide, a derivative of niacin, which has proven beneficial in treatment of acne and skin cancer, to topical gels.
