Cosmetic Grade L-Valine(CAS 72-18-4)
Cosmetic-grade L-Valine is a high-purity essential branched-chain amino acid refined by advanced biological fermentation technology, which is an indispensable nutritional active substance for human skin growth and metabolism.
With a unique branched-chain molecular structure, it has superior skin affinity and permeability, which can efficiently penetrate the basal layer of the skin, supplement skin nutrients, activate cell vitality, and relieve skin dullness and fatigue caused by external environmental stress such as ultraviolet rays and dryness.
L-Valine can effectively scavenge free radicals in the skin, reduce oxidative damage, delay skin aging, and improve fine lines and dry lines. It participates in the synthesis of skin keratin and collagen related substances, helps strengthen the skin barrier structure, improves skin firmness and elasticity, and reduces sagging problems.
The product is mild and skin-friendly, with stable acid-base properties, no irritation to sensitive skin, no burden on the formula, and excellent compatibility with various amino acid raw materials, moisturizers and anti-aging ingredients. It is a high-quality core functional raw material for anti-oxidation, anti-wrinkle, firming and repairing skin care products.
