| Aliases | Melanostatine-5, MC1R antagonist peptide, Skin-brightening nonapeptide, Depigmenting peptide |
| Category | Skin & Hair |
| Formula | C₄₅H₆₅N₁₃O₁₂ |
| Molecular weight | 980.1 Da |
| Half-life | topical (negligible systemic absorption) |
| Mechanism (summary) | Nonapeptide-1 is a synthetic depigmenting peptide used primarily in cosmetics and skin-brightening research. It is framed as a melanogenesis-modulating peptide rather than a repair peptide or nootropic, and works upstream by antagonizing the α-MSH / MC1R axis. |
| Dosing notes | There is no standardized systemic human dose. Nonapeptide-1 is used topically in cosmetic formulations; concentrations vary by product. |
| Storage |
No universal product-specific storage standard was identified. Finished cosmetic formulations should follow label instructions. For raw peptide material: dry, light-protected cold storage, usually around -20°C for lyophilized material. |
