• 1. Melatonin (Melatonine) CAS 73-31-4 is a multifunctional whitening and anti-aging beauty ingredient with 99% HPLC high purity. As a premium custom cosmetic raw material, it is widely used in high-end whitening, brightening and spot-fading skincare formulations, with customizable specifications and packaging services available.

     Beyond its well-known circadian regulation function, Melatonin delivers remarkable skincare benefits. For whitening and spot fading, it inhibits tyrosinase activity to reduce melanin synthesis and deposition, effectively lightening dark spots, sun spots and melasma, evening out skin tone and brightening dull complexion. As a potent endogenous antioxidant with superior free radical scavenging ability compared to vitamin C and E, it protects skin from UV and environmental oxidative damage, delays photoaging, promotes skin barrier repair and enhances skin's natural defense. It also works synergistically during nighttime skincare to support skin self-repair during sleep, making it a popular active ingredient in night repair and whitening products.

     Cosmetic grade quality with mild low-irritation formula, perfectly compatible with whitening serums, spot-fading creams, night repair essences and antioxidant formulations, and can be combined with niacinamide, tranexamic acid and vitamin C derivatives for enhanced whitening effects. We are direct manufacturer with sufficient stock from gram samples to kilogram bulk orders, supporting custom packaging, concentration and private labeling to meet diverse customer needs. Every batch passes full-range quality inspection with complete COA, HPLC and MS test reports, fully compliant with international cosmetic raw material export standards.
