These Korean Vitamin C Serums Deliver Instant Glow Anytime, Anywhere

FAQ

What is the difference between Korean vitamin C serum and Western vitamin C serum?

Korean vitamin C serums, unlike some Western formulas, emphasize the long game over instant gratification. Instead of relying heavily on high doses of pure L-ascorbic acid, which can be irritating, Korean versions often use stabilizing derivatives layered with barrier-supporting ingredients, which can be combined with soothing ingredients such as cica to increase tolerance and keep the skin balanced, says Dr. Hsu. You’ll also notice a lighter, more fluid texture that’s designed to be easily inserted into multi-step routines. That said, our experts emphasize that formulation is more important than ingredients, with L-ascorbic acid still being the most important. I studied well It’s a form of vitamin C, so it’s always worth checking the ingredient list.

Are Korean vitamin C serums generally suitable for sensitive skin?

Korean vitamin C serums are often better suited for sensitive skin types, but that’s not always the case. In general, Korean skin care is often formulated with hypoallergenic and barrier-supporting ingredients, which can be especially helpful for those with sensitive skin if they have concerns such as dullness or a more even skin tone. But that doesn’t mean all formulas are safe. “Some Korean vitamin C products contain essential oils and fragrances, so check the ingredients list instead of assuming that K-beauty means gentle,” says Dr. Hsu.

Does Korean vitamin C serum oxidize quickly?

Many Korean vitamin C serums are slow to oxidize. “But it has less to do with being Korean and more to do with the type of vitamin C used,” Dr. Kim says. Formulations that rely on stabilizing derivatives such as ethyl ascorbic acid or ascorbyl glucoside are naturally more resistant to oxidation than pure L-ascorbic acid, no matter where they are manufactured. “However, regardless of the form in which it is used, it is important to store it properly, away from light, air and heat,” adds Dr. Xu.
