Nonapeptide-1 is a synthetic biomimetic peptide designed to regulate melanin synthesis in skin cells. It functions as a melanocyte-stimulating hormone (MSH) antagonist, helping to reduce hyperpigmentation and even skin tone. This peptide has gained attention in cosmetic dermatology for its skin brightening properties and ability to address photoaging concerns.
Typically applied topically in cosmetic formulations at concentrations ranging from 0.5% to 2%. Often incorporated into serums, creams, or nanoparticle delivery systems for enhanced penetration. Application is generally twice daily to affected areas for pigmentation concerns, with visible results expected after 4-8 weeks of consistent use.
Nonapeptide-1 acts as a competitive antagonist of melanocyte-stimulating hormone (MSH) at melanocortin receptors, particularly MC1R. By blocking MSH binding, it inhibits the activation of tyrosinase and other melanogenic enzymes, thereby reducing melanin production in melanocytes. This mechanism helps prevent and reverse hyperpigmentation, age spots, and uneven skin tone associated with UV exposure and aging.
