ABSTRACT:  Peptide cosmeceuticals are one of the new, popular options to treat aging skin. There are three main categories of cosmeceutical peptides: signal peptides, neurotransmitter-affecting peptides and carrier peptides. Although their benefits currently may not be as rigorously tested as most FDA-regulated drugs, the evidence to support their use is growing. This article attempts to review the various current popular cosmeceutical peptides, the published studies on their theoretical effects, and their practical use in dermatology.
