How Long Might a Melanotan 2 Tan Last?

A fixed fade calendar is an attractive promise but cannot be established for every person. Skin tone, UV exposure, product composition and how the change is measured all affect any observation.

What “lasting” would need to measure

A credible study would define the exact product, baseline skin colour, measured change, follow-up dates and UV exposure. Anecdotal estimates such as a set number of weeks are not a reliable prediction for another person.

Ongoing UV changes the question

Sun or sunbed exposure can change skin colour and carries its own risks. A darker appearance does not provide meaningful permission to stay in the sun longer. NHS sun-safety advice applies regardless of a tan.

Avoid using colour as a safety signal

Cancer Research UK warns that marketed Melanotan products have not been tested for safety, quality or effectiveness. Our separate timeline-claims article explains why different photographs and personal stories cannot establish a universal duration.
