The COSRX Vitamin C 23 Serum is a highly concentrated formula designed to revitalize and brighten your complexion. Enriched with 23% pure Vitamin C (L-Ascorbic Acid), it stands as a potent antioxidant that shields the skin from environmental stress and free radicals. Simultaneously, it works to even out and illuminate the skin tone. The serum's composition is enhanced with Hyaluronic Acid, Tocotrienol, and Allantoin, which together soothe the skin, boost collagen production, and hydrate. Its lightweight nature makes it suitable for all skin types, including sensitive skin. For optimal results, start with once or twice weekly applications, gradually increasing to daily use. Always pair with broad-spectrum sunscreen during the day when using Vitamin C products to protect from increased sun sensitivity.

Gently shake the bottle 1-2 times during the serum phase after cleansing. Apply a few drops to the skin. Gently massage the serum into the skin, moving from the inside of the face outwards.
