A melanocyte-stimulating hormone analog; studied for its relationship with skin pigmentation via melanocortin receptors.
Last reviewed: August 16, 2026 · How we verify this
The ground it plays on
In aesthetics the route of administration decides almost everything. A peptide that works in a fibroblast culture may not cross intact skin, and then the formulation matters more than the active ingredient. That is why two products listing the same ingredient can give completely different results.
What it is studied for
Pigmentation, skin tone.
There is a distinction that almost always gets lost. A compound being studied for something is not the same as achieving it. And even where it works in a dish or in a mouse, that says little about whether it works in a person or whether the benefit is worth the risk. The section below therefore carries more weight than everything above it.
What the human evidence says
Afamelanotide is an approved drug with randomized trials showing longer pain-free light exposure and better quality of life in erythropoietic protoporphyria.
The limitation that matters most
Its only approved indication is erythropoietic protoporphyria, in the form of an implant placed by a physician at accredited centers. Using it as a tanning agent is off-label, requires dermatological monitoring of moles and has been associated with a drop in vitamin D.
Regulatory status
Approved by the EMA (2014) and the FDA (2019) as Scenesse, solely for erythropoietic protoporphyria.
Status can change and varies by country. Always verify the rules in force where you live before drawing conclusions.
Cautions and context
Variable individual responses; monitoring moles and skin changes is advisable. Long-term evidence and safety are limited.
With a history of skin lesions or melanoma, dermatological assessment is essential.
What this page cannot give you
A reference page can take you this far. You know what Melanotan I is and where its research stands, which already puts you ahead of most readers. Four questions remain that no encyclopedia can answer for you, because the answers depend on your own situation:
- What would you measure beforehand, so that later you could tell whether anything actually changed?
- What would you watch along the way, and how consistently?
- What would you ask a professional, and in how much detail, so you do not walk out with a textbook answer?
- What would make you stop?
That is what the course is for
PeptiXtreme is ${CIF.LECCIONES} lessons that hand out no numbers. Each one ends with your starting point, what to watch along the way, the specific questions you take to a professional and the signals that mean stop. It includes per-module exams, a diploma with a verifiable folio, a record to track how you progress, and a human advisor you can actually write to.

Frequently asked questions
What is Melanotan I?
A melanocyte-stimulating hormone analog; studied for its relationship with skin pigmentation via melanocortin receptors. It is studied within the area of aesthetic.
Is there human evidence for Melanotan I?

Is it approved by any health agency?
Approved by the EMA (2014) and the FDA (2019) as Scenesse, solely for erythropoietic protoporphyria.
What is the dose of Melanotan I?
We do not publish dosages. This is not an oversight. No single figure works for everyone: the regimen depends on a person's medical history, on whatever medication they already take, and on the goal they are chasing, which is something a professional weighs with the case in front of them. What you can build is the ability to walk into that appointment knowing what to ask.
Where can I learn to evaluate this properly?
