Does melanotan permanently change the color of your skin?

No, it lasts for two to three months and is only available through injection. It is very similar to getting a real tan, without the damage of sun exposure because the drug increases your body's ability to create melatin, the pigment for darker skin. However, be careful because it is not approved by the FDA and has not yet been fully tested on humans. The effects of taking this drug years from now are unknown. So, use at your own risk.
