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.

• Smooths and Firms: Adenosine and Vitamin C work together to improve skin elasticity and reduce fine lines.

• Soothing Hydration: Infused with Panthenol, Allantoin, and Squalane to minimize the tingling or irritation often associated with high-strength actives.

• Clinical Results: Proven to improve skin radiance by over 30% and reduce the appearance of pores within 4 weeks of use.
