Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York, previously told mbg that vitamin C serums are typically used to brighten the skin, even out skin tone and fight stress. oxidative. As a topically applied antioxidant, he notes that vitamin C “protects the skin against free radicals, blocks the production of abnormal pigmentation, and acts as a cofactor for the production of new collagen.”

The only problem? When exposed to air, heat, or light, ascorbic acid (the most effective form of topical vitamin C) may become less effective in providing vitamin C benefits for the skin. However, research shows that combining vitamin C with other antioxidants can help stabilize vitamin C and improve its bioeffectiveness in topical products.

A 2017 review article by The Journal of Clinical and Aesthetic Dermatology found that combining vitamin C with the plant-based antioxidant ferulic acid helps stabilize vitamin C molecules. Additionally, ferulic acid helps reduce the pH of ascorbic acid below 3 .5, which is found to be an effective method of improving the permeability of vitamin C (i.e. its absorption capacity) when applied to the skin.
