Decapeptide-12- Summary
- 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.
- Decapeptide-12 is a synthetic 10-amino acid peptide developed for skin brightening and depigmentation. It selectively inhibits tyrosinase activity and downstream melanogenesis pathways, reducing hyperpigmentation, dark spots, and uneven skin tone without the irritation associated with hydroquinone.
- Half-Life
