Common cosmeceuticals

In the cosmetic arena, many materials are used commercially and claim to provide skin effects (eg, antiaging effects) when used topically. Considering there are so many such materials and many skin appearance effects are encompassed, this short contribution must, by necessity, be selective in terms of the number of materials discussed and the depth with which any particular material is overviewed. This presentation, therefore, focuses on only 10 types of cosmeceutical agents: five vitamins (A, B3, C, E, panthenol), peptides, hydroxyl acids, sugar amines, ceramides, and metals. In particular, this contribution concentrates on those materials for which there are available clinical data that support a reported skin appearance improvement effect.
