K-beauty's secret weapon: why korean vitamin c is a game changer

Forget the chalky formulas and limited brightening power of Western vitamin C serums. A revolution is brewing in skincare, and it’s coming straight from Seoul.

Decoding the difference: korean vs. western vitamin c

While you’re stocking your cabinet with K-Beauty toners and sheet masks, you might be considering swapping your traditional brightening agent for a Korean vitamin C serum. But what you need to know first is that vitamin C serums as we know them stateside look a bit different in Seoul. “Vitamin C is a popular ingredient in Korea, but I’d say it’s less of the star of the show there compared to Western brands,” Michelle Lee, former EIC of Allure and CMO at K-Beauty World, tells Vogue. “Brightening in K-Beauty is a category, not a single hero ingredient.”

Instead of focusing on a single, potent dose of ascorbic acid, Korean formulas embrace a layered approach. They expertly blend ingredients like niacinamide, tranexamic acid, kojic acid, and rice extract – creating a synergistic effect that delivers noticeable results. Board-certified general and cosmetic dermatologist Jenny Liu agrees, adding that vitamin C can assist in “achieving the bright, even-toned complexion that underpins the ‘glass skin’ aesthetic.”
