Research Overview
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.
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.
