Cosmetic Grade L-Lysine,Essential Amino Acid(CAS 56-87-1)
Cosmetic-grade L-Lysine is a high-purity essential amino acid refined by advanced biological fermentation and purification technology, which is an indispensable nutritional raw material for human skin tissue growth and repair. As a basic structural unit of skin collagen and elastin, it can directly participate in skin cell metabolism and fibrous tissue synthesis, effectively replenish skin nutrient deficiency, and fundamentally improve skin aging problems such as sagging, dullness and loss of elasticity.
Different from ordinary moisturizing ingredients, L-Lysine has unique barrier repair activity, which can repair damaged stratum corneum gaps, reorganize skin lipid structure, enhance skin defense ability, and greatly improve dry, peeling, redness and sensitivity of fragile skin. It owns mild anti-inflammatory and soothing effects, which can relieve skin discomfort caused by external irritation, sun exposure and dry environment, stabilize skin microecology, and reduce repeated sensitivity.
In addition, L-Lysine can assist antioxidant ingredients to scavenge free radicals, inhibit oxidative aging, delay the generation of fine lines and dry lines, and keep skin plump and firm. With ultra-mild natural amino acid attributes, low sensitization and excellent formula coordination, it can be perfectly compounded with moisturizing, repairing and anti-aging ingredients. It is a core functional raw material for barrier repair, moisturizing and anti-aging maintenance in high-end skin care.
Key Benefits
• Essential Nutrition, Boost Collagen Regeneration: As a necessary amino acid for skin growth, it promotes collagen and elastin synthesis, improves skin sagging and loose texture, and enhances skin firmness and elasticity.
• Powerful Barrier Repair & Lock Moisture: Repair damaged stratum corneum, fill skin texture gaps, rebuild skin protective barrier, reduce water loss, and improve long-term dry and rough skin.
• Mild Anti-Inflammatory & Soothe Sensitivity: Relieve skin redness, dry itching and discomfort caused by external stimulation and sun damage, stabilize fragile skin, and reduce repeated sensitivity.
• Anti-Oxidation & Delay Skin Aging: Assist in scavenging skin oxidative free radicals, block aging chain reaction, fade fine dry lines, and improve dull and tired skin tone.
• Ultra-Mild & Low-Sensitivity Safety: Natural biological amino acid ingredient, pure and mild, zero irritation to skin, suitable for dry skin, sensitive skin and fragile skin long-term maintenance.
• Strong Formula Compatibility & Synergistic Effect: Perfectly compatible with moisturizing factors, panthenol, peptides and other repairing ingredients, significantly improve the comprehensive repair and anti-aging efficacy of finished products.
