Unlike Vitamin C (ascorbic acid), Vitamin C Ester is made of L-ascorbic acid joined with a fatty acid creating an ester bond.
Vitamin C Ester (10%) stimulates collagen production plus it is fat-soluble, making it stable, non-acidic, completely nonirritating to the skin and offers maximum protection against free radicals at the precise spot that they do the most damage outside of the cell.
