Peptides
There are numerous examples in physiology of peptide regulatory elements that play integral roles in basic homeostatic mechanisms such as injury-repair responses and other stimulus-response actions. Among these are well-known neuropeptides (e.g., bradykinins, endorphins); metabolism and fat storage regulators (e.g., neuropeptide Y, leptin, insulin); tanning and skin pigmentation-related peptides (e.g., α-MSH, ACTH, Agouti), and peptides involved in wound healing (e.g., FGF).
This large group of innovative cosmeceutical ingredients triumphed in the world of skincare products during the last two decades. Peptides are chains of amino acids that are attached in a specific order. Amino acids are naturally occurring in the body and are vital to everyday living processes. Peptides can be made up of 2 or more amino acids that can stimulate different responses within the body. As a result, peptides serve as tiny messengers that can be sent to kick the skin into gear and make it look better.
Peptides are leading a beauty revolution due to their excellent multi-functional properties; formularies are scrambling to access the latest advances in cosmetic peptide technology. In addition, their "Botox-like" performance, activation of collagen and elastin production, and skin-lightening effect make them very efficient against coarse wrinkles and hyperpigmentation of the skin.
