Melanotan is a self-administered injectable tan that works by stimulating the production of melanin. There are two different types of Melanotan:Â
- Melanotan 1 is a peptide that emulates the action and effects of the hormone that produces melanin. It has fewer side effects than Melanotan 2, but it’s harder to find and is more expensive.
- Melanotan 2 (sometimes “Melanton II” or “M-II”) also emulates the effects of the hormone that produces melanin. It isn’t the same chemical composition as Melanotan 1 but, rather, a shorter version of the same peptide called afamelanotide. Melanotan 2 side effects include dizziness, acne and other skin problems, and nausea. This injectable can also be used for erectile dysfunction, so side effects may include unintended arousal.
The manufacturer says Melanotan can make your skin darker without the risks associated with tanning beds and sun exposure. The company also claims that the tanning created by the injections can protect against skin cancer.
