L-α-Glycerophosphocholine, Cosmetic Grade GPC, Skin Cell Repair, Deep Hydration, Anti-aging, Skin Brightening, Moisturizing Skincare Raw Material
L-α-Glycerophosphocholine(CAS 28319-77-9)
Cosmetic Grade L-α-Glycerophosphocholine is a high-purity natural cell phospholipid active ingredient, which exists in human skin tissues naturally. As a core precursor of skin phospholipid synthesis, it participates in the construction of skin cell membrane structure and cell metabolism cycle, different from traditional superficial moisturizing and anti-aging ingredients.
GPC can efficiently penetrate the skin epidermal layer, supplement the missing glycerophosphocholine in aging skin, promote the synthesis of lecithin and phospholipids, repair damaged and incomplete cell membranes, enhance cell activity and stability, and fundamentally improve skin dryness, sagging and dullness caused by cell aging.
It has excellent deep moisturizing performance, which can lock skin moisture for a long time, relieve dry tightness and fine dry lines. Meanwhile, it can scavenge skin free radicals, inhibit oxidative damage of cells, delay skin aging process, improve rough and dull skin texture, and restore skin delicate and translucent luster.
With pure natural skin-friendly properties, non-irritating and non-sensitizing, wide pH adaptation range and excellent formula compatibility, it does not affect the color, fragrance and viscosity of finished products. It is an indispensable core raw material for high-end cell-level repair, moisturizing and anti-aging skincare products.
Key Benefits
•Cell-level Repair, Fundamental Anti-aging: Natural skin homologous phospholipid component, repair damaged cell membranes, activate skin cell metabolism, delay cell aging, and solve aging problems from the source, more thorough than traditional skincare ingredients.
•Deep Long-lasting Hydration, Improve Dry Skin: Different from superficial water replenishment, it builds intracellular water-locking system, long-term moisturizing, relieves dry tightness, dry lines and peeling, and keeps skin moist and tender all day.
•Promote Phospholipid Synthesis, Firm Skin Texture: Supplement skin core lipid nutrients, accelerate phospholipid regeneration, enhance skin tissue density and elasticity, improve sagging and loose skin, and refine skin texture.
•Anti-oxidation & Brighten Dull Complexion: Scavenge skin free radicals, resist cellular oxidative aging, improve tired dull and yellowish skin, uniform skin tone, and restore skin translucent luster.
•Natural Homologous & Ultra-mild Safety: Human skin endogenous active ingredient, high skin affinity, non-irritating, non-sensitizing, no burden on skin, suitable for sensitive skin and fragile delicate skin maintenance.
•High Formula Stability & Easy Mass Production: Fully water-soluble, stable in full pH range, compatible with all mainstream skincare active ingredients, no discoloration and no inactivation, low dosage and high efficiency, convenient for industrial production.
Applications
• High-end Moisturizing & Repair Essence: Core active ingredient of deep moisturizing essence and cell repair stock solution, realize intracellular water locking and cell damage repair, and improve dry and aging skin fundamentally.
