Ascorbyl Tetraisopalmitate
Product Introduction
Ascorbyl Tetraisopalmitate is a stable, oil-soluble form of vitamin C. Also famous as Tetrahexyldecyl Ascorbate,VC-IP,THDA or THD.It helps support skin’s collagen production and promotes a more even skin tone. As it is a powerful antioxidant, it fights free radicals that damage skin. Ascorbyl Tetraisopalmitate gives you all the benefits of Vitamin C without any drawbacks of L-Ascorbic acid. Ascorbyl Tetraisopalmitate brightens and evens skin tone, fights free radical damage, and supports our skin’s collagen production, while being extremely stable, non-irritating.


Compared with the water-soluble vitamin C that will eventually be excreted from the body, this fat soluble Vitamin C Ascorbyl Tetraisopalmitate offers significant and long-lasting effect, and is much more stable and gentle,non-irritation. It promotes collagen synthesis to prevent skin from aging, improves cell reproduction to slow down the aging process, and reduces skin melanin production.
