Serum C20’s stabilized vitamin C corrects all the drawbacks of synthetic vitamin C while optimizing its action. Made in France, this stabilized vitamin C is obtained from active vitamin C and isopalmitic acid (a fatty acid not derived from palm trees). Both of these substances are of biotechnological origin, in which non-GMO corn sugars undergo fermentation. As a result, absorption is optimized (epidermis + dermis), which gives it more extensive antioxidant action and allows it to increase collagen synthesis by a factor of 8.
