COSRX The Vitamin C 23 Serum is a powerful serum featuring a 23% concentration of pure L-ascorbic acid, also known as vitamin C. This antioxidant not only shields against environmental stress and free radicals but also improves skin tone, making it an excellent choice for anyone seeking the best serum for uneven skin texture.

Combined with hyaluronic acid, tocotrienol, and allantoin, this serum soothes, boosts collagen production, and deeply hydrates the skin. Its lightweight formula is suitable for all skin types, including sensitive skin, and provides the benefits of a vitamin C serum with hyaluronic acid and retinol.

NOTE: Please note the serum has a natural yellow tint and does not mean it has oxidized.
