●Ascorbyl Tetraisopalmitate is one of the VC derivatives family, Its two long palmitic acid structures are esterified with the VC hydroxyl group, which makes it is more stable than the general VC.
●Most of the VC derivatives are water-soluble, while ZLEY@VCIP is an oil-soluble ingredient that can penetrate sebum and enter the epidermis and dermis, which can be quickly absorbed by the skin and then converted into an active VC to play its role. That is, Its oil solubility allows it to penetrate deeper than other popular vitamin C derivatives. The transdermal absorption ability is over 10 times of water-soluble vitamin C, and the VC conversion rate reaches up to 84%;
●ZLEY@VCIP has better effect on antioxidant and inhibition of melanin than other water-soluble VC;
●Ascorbyl Tetraisopalmitate is gentler than the water-soluble VC, good tolerance, does not stain the cuticle, applied by day and night, suitable for sensitive skin.
