Melanotan & Melanotan 2: Origins & Evolution

The names Melanotan I and Melanotan II arise from research on synthetic analogues of alpha-melanocyte-stimulating hormone. Early research, later medical authorisation of a specific medicine, and today’s retail tanning claims are different chapters.

Early melanocortin research

A 1991 human study examined pigmentation after a synthetic alpha-MSH analogue in a small group of participants. It was a defined research compound and setting, not a test of current online vials or nasal kits. A 1996 pilot study examined a cyclic peptide called Melanotan-II. A pilot study cannot establish broad safety or equivalence among retail products.

Distinct compounds and authorisation

Melanotan I and II are related, not identical names. The EMA’s Scenesse record concerns a particular afamelanotide implant for erythropoietic protoporphyria. Its medical authorisation does not approve Melanotan II cosmetic tanning items or authenticate a product bearing “Melanotan I” in an online listing.

What the history cannot prove

Increasing pigmentation does not establish UV protection. The chronology above cannot establish that a particular Melanotan II product is more stable or potent. Cancer Research UK cautions that Melanotan tanning products have not been shown safe and effective and that a tan does not replace sun protection. See its guidance.
