Acetyl Hexapeptide-1

Acetyl Hexapeptide-1, commercially known as Melitane, is a synthetic melanocortin receptor agonist peptide widely used in cosmetic formulations for its ability to stimulate melanin production. By binding to MC1R receptors on melanocytes, it triggers the natural tanning cascade without requiring UV radiation exposure.

This peptide provides a safer alternative to traditional tanning methods, offering consistent, natural-looking pigmentation results. With high purity (>98%) and excellent solubility in water-based formulations, Acetyl Hexapeptide-1 is compatible with a wide range of cosmetic delivery systems including serums, creams, and lotions.

Clinical studies demonstrate that Melitane produces measurable increases in melanin content within 7-14 days of topical application, with results comparable to moderate sun exposure but without the associated DNA damage risks. It is a valuable ingredient for sunless tanning products, photoprotection formulations, and pigmentation-related cosmetic applications.
