Melanotan 1- Summary
- Palmitoyl Dipeptide-6 is a synthetic dipeptide (lysine-threonine) with a palmitoyl fatty acid tail, designed to penetrate the skin barrier and stimulate the extracellular matrix components essential for skin firmness. It activates fibronectin and type IV collagen synthesis, improving skin density and firmness particularly in mature or sagging skin.
- 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.
