Cosmetic Grade D-Serine(CAS 312-84-5)
Cosmetic-grade D-Serine is a high-purity chiral amino acid refined by advanced biological synthesis and purification technology, which is a targeted anti-glycation functional raw material exclusive to high-end skin care. Different from conventional L-series amino acids, D-Serine has unique stereoscopic molecular activity, which can precisely inhibit the skin glycation reaction, block the production of AGEs glycation toxins, and fundamentally improve skin yellowing, dullness and relaxation caused by glycosylation aging.
It has super hydrophilic moisturizing performance, can lock basal skin moisture for a long time, relieve dryness and tightness, and maintain skin long-lasting hydration and elasticity. Meanwhile, D-Serine participates in the synthesis of skin ceramides and intercellular lipids, effectively repairing damaged skin barriers, improving skin fragility and sensitivity, and enhancing skin self-tolerance.
With ultra-mild skin-friendly properties, stable acid-base activity, no irritation and no burden on sensitive skin, it can be perfectly compounded with anti-oxidation, anti-aging and brightening ingredients to achieve multi-dimensional skin care effects of anti-glycation, moisturizing and repair. It is a core high-quality raw material for improving sugar-aged skin and daily barrier maintenance.
Key Benefits
• Targeted Anti-Glycation & Anti-Sugar Aging: Precisely inhibit skin glycation reaction, block AGEs generation and deposition, improve skin yellowish, dull and turbid complexion caused by sugar aging, and restore clear skin tone.
• Deep Hydration & Long-Lasting Moisturizing: Super hydrophilic molecular structure, quickly replenish skin basal moisture, form a water-locking protective film, relieve dry tightness and peeling, and keep skin hydrated all day long.
• Repair Barrier & Stabilize Sensitive Skin: Promote the synthesis of skin ceramide and intercellular lipids, repair damaged barrier, reduce redness and sensitivity, and enhance skin defense capability.
• Delay Collagen Aging & Firm Skin: Protect collagen from glycation damage, prevent collagen brittle aging and breakage, improve facial sagging and fine lines, and maintain skin firmness and elasticity.
• Ultra-Mild & Zero Irritation: High-purity refined amino acid ingredient, skin-friendly pH value, low sensitization and zero irritation, safe for long-term use in sensitive skin and mild formulas.
• Stable Formula & Strong Synergy: Excellent formula stability, not easy to oxidize and inactivate, highly compatible with antioxidants and brightening ingredients, multi-dimensional synergistic anti-aging and skin beautifying effects.
Applications
• Anti-Glycation Brightening Skin Care Series: Core functional raw materials for anti-sugar essence, yellowing removal lotion and brightening cream, specially improving sugar-aged dull and yellow skin.
• Skin Barrier Repair Products: Applied in sensitive skin soothing lotion, barrier repair cream and postoperative mild maintenance products to repair damaged skin and stabilize skin health.
• Anti-Aging Firming Functional Formulas: Added in anti-aging firming essence, wrinkle smoothing cream and anti-relaxation skin care products to delay glycation aging and improve skin elasticity.
• High Moisturizing Daily Skin Care: Suitable for high-efficiency moisturizing milk, facial mask and dry skin care products to relieve dryness and lock water for a long time.
• High-End Mild Cosmetics: Used in high-end comprehensive anti-aging compound formulas, perfect for sugar-oxygen aging improvement and daily skin delicate maintenance.
