ACETYL SH-NONAPEPTIDE-5

Description

Acetyl SH-Nonapeptide-5 is a synthetic peptide designed to target melanin production in the skin. This innovative ingredient functions as a tyrosinase inhibitor, effectively reducing the formation of melanin and addressing hyperpigmentation concerns. The acetyl group attached to the peptide enhances its stability and skin penetration capabilities.

The nonapeptide structure consists of nine amino acids carefully sequenced to interact with specific cellular pathways involved in melanogenesis. By interfering with the tyrosinase enzyme, Acetyl SH-Nonapeptide-5 helps to regulate melanin synthesis, potentially leading to a more even skin tone and reduced appearance of dark spots.

Clinical studies have shown promising results in the treatment of melasma and post-inflammatory hyperpigmentation when using formulations containing this peptide. Its efficacy is comparable to some traditional skin-lightening agents, but with a potentially improved safety profile. Acetyl SH-Nonapeptide-5 is typically incorporated into serums, creams, and targeted treatments at concentrations ranging from 0.5% to 2%.

This ingredient is particularly suitable for individuals seeking non-hydroquinone alternatives for managing hyperpigmentation. It can be combined with other brightening agents like vitamin C or niacinamide for enhanced results.
