While the Food, Drug, and Cosmetic Act does not recognise the term "cosmeceutical", the cosmetic industry has begun to use this word to refer to cosmetic products that have drug-like benefits.

While drugs are subject to an intensive review and approval process by FDA, cosmetics are not approved by FDA prior to sale. If a product has drug properties, it must be approved as a drug.

Cosmetics
" Articles intended to be applied to the human body for cleansing, beautifying, promoting attractiveness or alternating the appearance without affecting the body structure or function." Many cosmetics alter their advertising to meet these guidelines, such as antiwrinkle creams, since they would otherwise be considered a drug. For example, "to reduce the appearance of fine lines", whereas a drug such as Retin-A actually does reduce fine lines, and thus is actually affecting the structure of the skin--not just changing its appearance.
