Best Price Cosmetic Peptide Skin Whitening Decapeptide-12 Powder CAS 137665-91-9
Product Introduction
Its core whitening mechanism relies on competitive combination with the copper active site of tyrosinase, the key enzyme triggering melanin synthesis. It efficiently suppresses pigment generation without damaging healthy melanocytes, avoiding common adverse reactions like ochronosis and permanent hypopigmentation caused by hydroquinone.
Features
Chemically stable across regular cosmetic pH ranges, it mixes well with niacinamide, tranexamic acid and retinol to realize synergistic brightening effects. Mild and non-irritating, it suits sensitive skin and dark skin tones for long-term daily use, requiring sealed storage at 2–8 ℃ away from direct sunlight to retain activity.
1. High-efficiency tyrosinase inhibition：Competitive binding with tyrosinase to block melanin synthesis.
2. Dual-function, brightening+anti-photoaging: Eliminate free radicals and repair UV-induced skin damage.
3. Excellent formulation compatibility: Compatible with toner, serum, cream. Synergize well with niacinamide, tranexamic acid, azelaic acid and Vitamin C. Suitable for day & night skincare formulas.
4. Good chemical stability: Stable against moderate acid, alkali and heating during production, hardly deactivate in finished formulas, easy for large-batch cosmetic manufacturing.
Product Application
The recommended addition proportion in finished cosmetics falls between 0.01% and 0.5%. Formulators regularly incorporate this powder into brightening serums, spot-removal creams, repairing facial masks and under-eye essences to improve sun spots, melasma, post-inflammatory hyperpigmentation and sallow uneven complexion.
Apart from concentrated skincare items, it is also applied in skincare-infused foundations and tinted moisturizers to achieve natural all-day skin tone correction and translucent brightening effects.
