Copper Tripeptide (Copper Tripeptide-1) – GHK-Cu

INCI – Copper Tripeptide-1 CAS Number: 299157-54-3 Appearence – Bluish to bluish purple clear solution Usage Percentage: 1 to 5% Solubility: Water Soluble pH: 5.5 to 7 Purity (HPCL): ≥99% Liquid copper tripeptide, widely known as copper tripeptide-1 or GHK-Cu, is extensively used in cosmetics for its scientifically recognized effects on skin regeneration, anti-aging, and repair. PeptiCure™ 5000 (Copper Tripeptide-1 / Solution 5000ppm) boosts collagen and elastin production for firmer, wrinkle-free skin. It soothes inflammation, accelerates skin repair, and minimizes scarring, making it ideal for post-acne care. In hair care, it supports follicle health and stimulates growth for a stronger scalp. A powerful ingredient for advanced skin and hair rejuvenation formulas. 1-5% Key applications and benefits in cosmetic products include: Anti-aging and firming: Stimulates collagen and elastin synthesis, reducing fine lines and wrinkles while improving skin firmness and elasticity. Skin regeneration and repair: Promotes faster recovery from micro-damages, helps heal scars, soothed irritated or compromised skin, and accelerates tissue repair. Brightening and evening skin tone: Fades hyperpigmentation, dark spots, and acne scars, resulting in a more uniform complexion. Antioxidant and anti-inflammatory action: Provides protection against oxidative stress and environmental damage, while calming inflammation and redness. Enhanced skin barrier: Strengthens the skin’s protective barrier, improving moisture retention and resilience. Application versatility: Used in water-based serums, creams, essences, facial mists, and other advanced formulations. Cosmetic formulation and use: Usually added at concentrations of 1–2% in skin care products, incorporated during the cool-down phase of formulation (<40°C) to preserve activity. Works well when combined with hydrosols, aloe vera, or soothing actives, but should not be mixed directly with strong acids (AHA/BHA), retinol, or high concentrations of vitamin C to avoid reduced efficacy. Typically applied after cleansing, both morning and night, followed by moisturizer or sunscreen as needed for optimal results. Mechanistic insights: Penetrates skin effectively, delivering copper ions through the peptide carrier, which boosts cellular repair and renewal cycles. Modulates collagen, elastin, and glycosaminoglycan production, essential for youthful-looking skin. Acts as a signal and carrier peptide, stimulating skin’s own healing and maintenance pathways. In summary, liquid copper tripeptide is prized as a multifunctional active ingredient focused on anti-aging, skin repair, and visible rejuvenation, and is incorporated into advanced cosmetic formulations for wide-ranging benefits and excellent safety
