PP New York, NY SN 9780071490627 LK dermatology.mhmedical.com/content.aspx?aid=1172447520 RD 2024/04/23 AB According to the United States Food and Drug Administration (FDA), a personal care product can be classified as a drug, a cosmetic, or both. Moisturizers with skin protection factor (SPF) and antidandruff shampoos are examples of dermatologic products classified as both a drug and a cosmetic. The term “cosmeceutical” was introduced approximately 25 years ago by Albert Kligman, MD, at a meeting of the Society of Cosmetic Chemists because he felt that a new category of regulation should exist.1 Although this topic has been debated for decades, the category “cosmeceuticals” has still not been codified or officially recognized. In other words, it has no legal meaning. The term, however, is increasingly a part of the mainstream vernacular and frequently used to describe products that are known to have a biologic action but are regulated as cosmetics (e.g., products containing retinol). Although it is well known that retinol stimulates retinoic acid receptors resulting in biologic activity, retinol is a popular ingredient contained in numerous cosmetics. Companies often list retinol as an inactive ingredient on product labels to avoid regulatory action by the FDA.
