COSRX The Vitamin C 13 Serum 20ml
COSRX The Vitamin C 13 Serum is a concentrated Korean facial serum formulated with 13% pure vitamin C to support a brighter, smoother and more radiant-looking complexion. Designed for skincare routines focused on dullness and uneven-looking skin tone, its lightweight formula combines antioxidant care with hydrating and skin-conditioning ingredients.
The formula features 13% ascorbic acid alongside 3-O-ethyl ascorbic acid, creating a dual vitamin C approach that helps improve visible brightness and overall luminosity. Niacinamide and glutathione complement the brightening profile, while tocopherol provides additional antioxidant support.
Panthenol, sodium hyaluronate and squalane help maintain hydration and comfort, balancing the concentrated vitamin C formula with ingredients that support smoother and more supple-looking skin. The serum absorbs quickly and layers easily beneath moisturizer and sunscreen.
Ideal for customers searching for COSRX vitamin C serum, Korean brightening serum, 13% vitamin C serum, antioxidant skincare or K-Beauty products for dull and uneven-looking skin, COSRX The Vitamin C 13 Serum delivers focused daily care in a compact, highly concentrated formula.
For daytime use, follow with a broad-spectrum sunscreen as the final step of the skincare routine.
