Upon afamelanotide binding with the MC 1 R on the surface of melanocytes in the epidermal layer of the skin, it begins a series of actions and reactions that result in melanocytes favoring the production of eumelanin (photoprotective black/brown pigment) over pheomelanin (red/yellow pigment)
Two Distinct Melanocortin-Targeting Peptides Both PT-141 and Melanotan 2 operate within the melanocortin receptor system, yet these peptides possess distinct structural features and functional profiles that make them fundamentally different research tools
