Cosmetic Grade L-Tyrosine(CAS 60-18-4)
Cosmetic-grade L-Tyrosine is a high-purity aromatic amino acid refined by advanced biological fermentation and purification technology, which is an indispensable functional raw material for skin color regulation and antioxidant maintenance.
As an important precursor of melanin synthesis in human skin, it can intelligently regulate melanin metabolic activity, avoid abnormal melanin overproduction caused by UV irradiation and oxidative stimulation, improve uneven skin tone, yellowish dullness and facial turbidity, and enhance skin natural translucency.
Different from ordinary brightening ingredients, L-Tyrosine owns excellent endogenous antioxidant capacity, which can effectively scavenge excess free radicals in the skin, block oxidative aging chain reaction, reduce skin oxidative damage, and delay the generation of fine lines and dull aging problems.
Meanwhile, it can promote the renewal and metabolism of skin keratinocytes, accelerate the discharge of aging waste keratin, refine rough skin texture, and make skin smooth and delicate. With ultra-mild natural amino acid attributes, skin-friendly pH value, zero irritation and low sensitization, it will not cause burden to the skin.
It can be perfectly compounded with VC derivatives, glutathione and other brightening and antioxidant ingredients to form a synergistic brightening system, significantly improving the comprehensive skin beautifying effect of finished products. It is a high-quality core raw material for natural brightening, anti-oxidation and anti-aging high-end skin care products.
Key Benefits
