COSRX The Vitamin C 23 Serum (20g/0.7oz)

Reveal brighter, smoother, and more even-toned skin with COSRX The Vitamin C 23 Serum, a highly concentrated formula featuring 23% pure L-ascorbic acid to target dullness, uneven texture, and visible signs of aging. This potent antioxidant fades acne scars, reduces the appearance of dark spots and wrinkles, and boosts radiance for a revitalized complexion.
Formulated with hyaluronic acid, tocotrienol (Super Vitamin E), and allantoin, the serum hydrates, soothes, and supports collagen production while minimizing potential irritation—making it suitable even for sensitive skin. Its unique two-layer structure helps slow oxidation and provides a smooth, moisturized finish.
Hypoallergenic, lightweight, and highly effective, this serum delivers powerful brightening results while keeping skin soft, balanced, and glowing. (Note: A natural yellow tint is normal and does not indicate oxidation.)
