What form of vitamin C is used in the Vitamin C Superserum?Updated a year ago

The Protocol Vitamin C Superserum contains L-ascorbic acid, which is the purest, most potent, and most bioavailable form of vitamin C - the same one found in nature. This is also the form that will show the greatest visible benefits to your complexion, from softening fine lines to visibly fading discoloration. The serum also includes some derivative forms of vitamin C, like magnesium ascorbyl phosphate (MAP)  and tetrahexyldecyl ascorbate, since your skin has some capacity to store them for later conversion into the real deal.
