Research Overview
ACTH
ACTH activates melanocortin receptors on melanocytes and can increase pigment synthesis. It is widely used as a reference peptide in studies of tanning, adrenal biology, and hyperpigmentation.
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.
