Research Overview
Beta-MSH
Beta-MSH is one of the endogenous melanocortin peptides studied for its ability to influence melanin synthesis. Most evidence is mechanistic, focusing on receptor signaling and melanocyte biology rather than cosmetic use.
Leuphasyl
Pentapeptide-18 has published cosmetic and formulation literature supporting its use in anti-aging skincare. Evidence is strongest for topical cosmetic smoothing rather than deep structural remodeling.
