Cosrx The vitamin C 23 serum 20ml

The COSRX The Vitamin C 23 Serum is a high-strength yet lightweight serum formulated with 23% pure vitamin C (ascorbic acid) to target dullness, hyperpigmentation, and uneven skin tone. It also contains tocotrienol (a potent form of vitamin E) and hyaluronic acid to provide antioxidant protection and hydration. The formula absorbs quickly, though it may cause slight tingling, especially for sensitive skin. With consistent use, it helps brighten the complexion, fade dark spots, and improve skin texture. However, due to its high concentration, it’s best introduced gradually into a skincare routine and stored properly to prevent oxidation.
