Advanced The Vitamin C23
COSRX Advanced The Vitamin C 23 Serum is a high-potency, dermatologist-tested treatment designed to fade acne scars, brighten the complexion, and target early signs of aging. Formulated with a massive 23% Pure Vitamin C (Ascorbic Acid), it works as a powerful antioxidant to neutralize free radicals and boost collagen production. This serum features a unique double-layered structure—a water-based serum beneath a thin oil layer—which helps stabilize the pure Vitamin C and prevent rapid oxidation. Enriched with Super Vitamin E (Tocotrienol) and Hyaluronic Acid, it balances high-strength brightening with essential moisture and soothing care.
Key Points:
-
Professional-grade Brightening: 23% Pure Vitamin C effectively targets stubborn hyperpigmentation and dullness.
-
Triple Antioxidant Care: Combines Vitamin C, Super Vitamin E, and Glutathione for maximum skin protection.
-
