COSRX Advanced The Vitamin C 23 Serum

Cosrx Advanced The Vitamin C 23 Serum is a high-strength brightening serum designed to improve the look of uneven tone, dullness, and early signs of aging. Formulated with 23% pure vitamin C (ascorbic acid), it helps support a clearer, more radiant-looking complexion while refining skin texture over time. The formula combines vitamin C with super vitamin E and glutathione, ingredients commonly used to enhance skin luminosity and antioxidant care. Panthenol, allantoin, and hyaluronic acid help maintain moisture levels and provide skin comfort, making the serum suitable for regular use despite its high concentration. With a smooth, fast-absorbing texture, this serum is ideal for those already familiar with vitamin C products and seeking focused tone and texture care. It leaves the skin looking brighter, more supple, and well-hydrated with consistent use
