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.
Endothelin-1
Endothelin-1 is one of the best-studied non-melanocortin regulators of pigmentation in human skin. It is strongly associated with UV-induced tanning responses and pigment disorder biology.
