Research Overview
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.
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.
