How It Works of Melanotan 1 peptide
Melanotan 1 peptide mimics a natural hormone that tells your skin to make more melanin. It's 10 times stronger than the natural version, so it works faster and lasts longer (about 3–4 hours in the body).

Melanotan 1 peptide binds to the melanocortin-1 receptor (MC1R) with 10x higher affinity than natural α-MSH, activating the cAMP/PKA signaling pathway.
This leads to:
- Increased tyrosinase activity (key enzyme in melanin synthesis).
- Enhanced production of eumelanin (dark pigment) and pheomelanin (light pigment).
- Reduced UV-induced apoptosis in melanocytes.
Its structural modifications (Nle⁴ and D-Phe⁷) improve metabolic stability, extending its half-life to 3–4 hours (vs. <1 hour for α-MSH).
Key Applications of Melanotan 1 peptide
Skin Tanning & Photoprotection
Stimulates melanogenesis, leading to a natural-looking tan while reducing UV-induced DNA damage.
Light Sensitivity Disorders
A pharmaceutical product indicated for erythropoietic protoporphyria (EPP) – a rare genetic disorder causing severe phototoxicity – has been granted marketing authorization by the European Medicines Agency (EMA). This information is supplied for scientific reference and research use only.
