Research Overview
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.
Tetracosactide
Tetracosactide is the synthetic ACTH(1-24) fragment and is commonly used to probe melanocortin receptor signaling. Its melanogenic relevance comes from the same N-terminal motif that drives ACTH-related pigmentation effects.
