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.
Gamma-MSH
Gamma-MSH has been investigated as part of the broader melanocortin network that regulates pigmentation. Evidence suggests it can contribute to melanocyte signaling, though its cosmetic use remains experimental.
