Cosmetic Grade L-Proline(CAS 147-85-3)
Cosmetic-grade L-Proline is a high-purity cyclic structured amino acid refined by advanced biological fermentation and purification technology, serving as one of the most core precursor substances for human skin collagen and elastin synthesis. Different from linear amino acids, its unique pyrrolidine cyclic structure endows it with superior molecular stability and skin affinity, which can directly participate in the proliferation and repair of skin fibroblasts, effectively promote collagen and elastic fiber regeneration, fundamentally improve skin relaxation, sagging, fine lines and dry wrinkles caused by collagen loss.
L-Proline owns excellent natural water-locking and moisturizing activity, which can bind skin water molecules to form a dense water-retaining protective layer, relieve long-term dryness, rough texture and tight peeling of dry skin, and maintain long-lasting skin plumpness and moisture.
Meanwhile, it has mild antioxidant and anti-aging effects, which can scavenge skin free radicals, reduce oxidative damage, delay skin tissue aging, and improve dull and tired skin tone. With ultra-mild neutral skin-friendly properties, zero irritation and low sensitization, it will not cause burden or irritation to fragile skin.
It can be perfectly compounded with various anti-aging peptides, moisturizing factors and repair ingredients to synergistically enhance the firming and anti-wrinkle efficacy of finished products. It is an indispensable core functional raw material for high-end anti-aging, firming and moisturizing skin care products.
Key Benefits
• Core Collagen Precursor, Anti-Wrinkle & Firming: Unique cyclic structure efficiently promotes collagen and elastin synthesis, fades dry fine lines and texture wrinkles, tightens loose skin, and restores skin firmness.
• Superior Water-Locking, Long-Lasting Moisturizing: Stably bind skin water molecules, form a breathable moisturizing film, relieve dry tightness and rough peeling, and maintain 24-hour plump and moist skin.
• Promote Skin Tissue Repair: Activate skin fibroblast activity, accelerate damaged skin tissue repair, improve fragile skin texture, and enhance skin self-repair ability.
• Mild Anti-Oxidation, Delay Skin Aging: Scavenge excess skin free radicals, reduce oxidative aging damage, improve dull and yellowish skin tone, and keep skin youthful and translucent.
• Ultra-Mild & Low-Sensitivity Safety: Natural cyclic amino acid, neutral skin-friendly pH, zero irritation, safe for sensitive skin, dry skin and long-term daily skin care.
• High Formula Compatibility & Stability: Excellent formula tolerance, not easy to deteriorate or inactivate, freely compoundable with peptides, vitamins and plant extracts to synergistically amplify skin care efficacy.
Applications
• Anti-Wrinkle & Firming Anti-Aging Series: Core functional raw materials for anti-aging essence, firming lotion, anti-wrinkle cream and lifting mask, targeting fine lines, sagging and loose skin texture.
• Dry Skin Deep Moisturizing Products: Applied in high moisturizing toner, long-lasting hydrating cream and dry skin care formulas to improve persistent dryness, rough peeling and tight skin.
