Melanotan 1- Summary
- Tripeptide-29 is a pro-collagen cosmetic peptide composed of proline, hydroxyproline, and glycine — the core repeating unit of collagen. Applied topically, it signals dermal fibroblasts that collagen degradation has occurred, triggering compensatory new collagen synthesis.
- Melanotan 1 (Afamelanotide) is a synthetic analog of α-MSH that selectively stimulates melanogenesis (tanning) through MC1R activation. It provides UV-independent skin pigmentation and is FDA/EMA-approved under the name SCENESSE for erythropoietic protoporphyria (EPP) and vitiligo.
