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.

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.
