What is Hexapeptide-9 Powder?
Hexapeptide‑9 Powder (CAS 122039‑38‑5, ≥98% HPLC) is a premium anti‑aging cosmetic peptide that strongly promotes collagen synthesis, improves skin elasticity, and reduces fine lines and sagging. With high water solubility and excellent stability, it is widely used in high‑end serums, firming creams, and repair skincare formulas. Our high‑purity lyophilized grade ensures consistent performance and easy formulation - trusted by global skincare brands for professional anti‑aging solutions.
High purity ≥98% (HPLC verified)
Excellent water solubility for easy formulation
Strong collagen‑boosting & firming effect
Stable lyophilized peptide grade
Ideal for anti‑aging, firming, and wrinkle‑care products
Hexapeptide-9 Powder Mechanism of Action
Core Mechanism of Action
Promotes Collagen & Elastin Synthesis: Stimulates dermal fibroblasts to produce collagen (types I, III) and elastin, enhancing skin's structural support and reducing fine lines/wrinkles.
Repairs Skin Barrier: Boosts synthesis of filaggrin and ceramides, strengthening the stratum corneum's moisture-locking ability and improving dry, sensitive skin.
Inhibits Matrix Metalloproteinases (MMPs): Reduces MMP activity to prevent collagen degradation caused by aging and environmental stress (e.g., UV rays), slowing skin sagging.
Main Efficacy
Anti-aging & Firming: Tightens facial contours, fades static wrinkles (e.g., nasolabial folds) and dynamic fine lines, making skin more elastic.
Barrier Repair: Relieves dryness, roughness, and redness, suitable for damaged or sensitive skin.
Improves Skin Texture: Enhances skin's smoothness and luster by regulating cellular metabolism and promoting healthy skin cell turnover.
Hexapeptide-9 Powder Application
Application Field: Primarily used in anti-aging, firming, and barrier-repair skin care products.
Common Product Types: Serums/essences (recommended concentration: 0.001%–0.005%), day/night creams (0.0005%–0.003%), eye creams (0.0005%–0.002%), and repair masks (0.002%–0.004%).
Formulation Compatibility: Works well with hyaluronic acid, niacinamide, other peptides (e.g., Acetyl Hexapeptide-8), and plant extracts (e.g., centella asiatica); avoid mixing with high-concentration alcohol (>20%) or oxidants.
