Cosrx The Vitamin C 13 Serum
Gentle brightening serum for everyday glow
Cosrx The Vitamin C 13 Serum is a lightweight, water-based formula designed to support clearer, brighter, and more balanced-looking skin.
Formulated with 13% pure vitamin C (ascorbic acid), this serum targets visible dark spots, uneven skin tone, and early signs of aging, while remaining gentle enough for daily use—even on sensitive skin.
The formula combines antioxidants such as vitamin C and tocotrienol (a potent form of vitamin E) to help protect the skin from external stressors. Additional ingredients like niacinamide and licorice root extract work to refine and brighten the complexion, while allantoin, panthenol, and hyaluronic acid support moisture retention and calm visible redness.
With a mildly acidic pH level between 3.0 and 4.5, the serum balances efficacy and skin comfort. It absorbs quickly without leaving a sticky residue, making it an easy addition to any morning or evening skincare routine.
This serum is well-suited for those looking to maintain a healthy-looking glow, smooth texture, and visibly even skin tone with a formula that prioritizes minimal irritation.
Looking for a stronger concentration? Cosrx The Vitamin C 23 Serum is also available for those who prefer a more intensive brightening care.
Size: 0.67 fl. oz / 20 ml
