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.
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.
