Tetrahexyldecyl Ascorbate is a very stable, oil-soluble Vitamin C ester which has anti-oxidant activity, inhibiting lipid peroxidation. Topical use can mitigate the damaging effects of UV exposure. Studies have shown it to stimulate collagen production as well as clarifying and brightening the skin by inhibiting melanogenesis (the production of pigment) thereby promoting a more even skin tone. Unlike ascorbic acid, it will not exfoliate or irritate skin.

INCI: Tetrahexyldecyl Ascorbate
