Cosmetic Grade Calcium L-Threonate(CAS 70753-61-4)
Cosmetic-grade Calcium L-Threonate is a high-purity natural sugar acid calcium salt functional raw material refined by advanced biological synthesis and purification technology. It has unique dual skin care mechanisms of antioxidant brightening and collagen repair, and is a new generation of mild and efficient anti-aging brightening ingredient popular in high-end skin care.
Different from traditional brightening raw materials, Calcium L-Threonate can efficiently scavenge skin free radicals, inhibit lipid peroxidation, reduce oxidative yellowing and dull and tired complexion, and continuously brighten skin tone from the source. It can effectively promote the proliferation of skin fibroblasts and collagen synthesis, repair aging and loose skin texture, smooth dry fine lines and dynamic wrinkles, and significantly improve skin elasticity and firmness.
In addition, it can regulate skin keratin metabolism, assist in repairing damaged stratum corneum, enhance skin barrier defense ability, reduce external environmental irritation damage, and improve fragile and dull skin quality. With neutral mild pH value, ultra-low irritation and excellent skin-friendliness, it will not cause sensitivity, redness and dry peeling.
It has high temperature resistance and stable physical and chemical properties, will not deteriorate or inactivate in conventional cosmetic production processes, and can be perfectly compounded with VC derivatives, nicotinamide, peptides and moisturizing factors to synergistically amplify brightening, anti-oxidation and anti-aging effects. It is an indispensable core raw material for high-end whitening, brightening and anti-aging skin care products.
