Description
Pep®-Radiance (Nonapeptide-1) is an advanced skin-brightening peptide used in cosmetic formulations aimed at reducing the appearance of dark spots, improving overall skin tone, and enhancing radiance. It is popular in serums, creams, and leave-on treatments due to its high efficacy and gentle nature.
Liquid Nonapeptide-1 is a pre-dissolved brightening peptide solution with special high concentration 2500ppm, It functions as a melanin-inhibiting peptide, blocking α-MSH from binding to the melanocyte receptors (MC1-R), therefore slowing melanin production.
It is gentle, non-irritating, suitable for all skin types for long-term use, and works well in leave-on formulations.
MECHANISM OF ACTION (How It Works)
Nonapeptide-1 targets the melanocortin-1 receptor (MC1-R) on melanocytes.
It prevents α-MSH from attaching, which:
✔ reduces melanin synthesis
✔ slows down dark spot formation
✔ helps the skin maintain an even tone
Unlike strong actives, it brightens without bleaching or irritation.
