Research Overview
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.
Beta-MSH
Beta-MSH is one of the endogenous melanocortin peptides studied for its ability to influence melanin synthesis. Most evidence is mechanistic, focusing on receptor signaling and melanocyte biology rather than cosmetic use.
