Brighten, smooth, and revitalize your skin with the COSRX The Vitamin C 23 Serum, a powerful antioxidant treatment formulated with 23% pure Vitamin C (L-Ascorbic Acid) to visibly fade dark spots, even out skin tone, and boost collagen production. This high-potency serum is ideal for those targeting pigmentation, acne scars, dullness, and early signs of ageing.
The formula also includes Super Vitamin E (Tocotrienol), Hyaluronic Acid, and Allantoin to hydrate, soothe, and protect the skin barrier, making it suitable for daily use while minimizing irritation. Despite its high concentration of Vitamin C, this serum absorbs quickly and leaves skin feeling smooth, radiant, and refreshed — not sticky or greasy.
For optimal results, pair with daily SPF and store in a cool, dark place to preserve ingredient potency.
