Evidence

Modest

How it works

This peptide is used in cosmetics with the aim of reducing the signal that drives melanin, the pigment that darkens skin, so the skin tone looks more even. Most of the supporting evidence is from laboratory and manufacturer studies.

What the evidence shows

There are studies, often from manufacturers, suggesting modest brightening effects on the look of skin. Independent, high quality trials are limited, so claims should be kept modest.

What it does not settle

• Independent high quality evidence is limited.
• Effects are usually modest and build slowly.
• Results depend on the product and how it is used.

Side effects

Common

• Usually well tolerated, though some people get mild irritation or redness. A patch test is sensible.

Report any suspected side effect through the MHRA Yellow Card scheme.

UK legal status and access

As a topical cosmetic ingredient with no medicinal claims, Melanostatin DM is legal and widely sold in skincare. Any version sold with medicinal claims would fall under medicines rules.
