Vogue’s Favorite Korean Vitamin C Serums

To start, there are three main forms of vitamin C: L-ascorbic acid, tetrahexyldecyl ascorbate, and 3-O-Ethyl-L-ascorbic acid. All have varying levels of stability and solubility. But regardless, vitamin C has three main benefits, says Dr. David Kim, a board-certified cosmetic dermatologist based in. New York City “For starters, it’s a great antioxidant and keeps the skin cells really healthy. It also has brightening properties, alongside UV protection, so it’s great to use during the summertime.”

Dr. Brezavscek previously told Vogue as well that “vitamin C is a powerful antioxidant that plays several important roles in skin health,” including helping protect the skin from environmental stressors like UV rays and pollution; supporting collagen production, and helping even out skin tone by fading dark spots and hyperpigmentation. “It’s one of the most well-studied and effective ingredients we have for brightening and protecting the skin,” Dr. Brezavscek added. To add the ingredient to your regimen, take stock of the best Korean vitamin C serums—a look at some Vogue editor and dermatologist favorites below.
