Research Overview
Argireline
Acetyl hexapeptide-3 has both in vitro and small human-cosmetic studies supporting a reduction in wrinkle depth or wrinkle appearance. Its best-supported role is as a topical cosmetic peptide rather than a systemic drug.
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.
