COSRX The Vitamin C 23 Serum (20g / 0.70 oz.)

Reveal a brighter, more youthful complexion with the highly concentrated COSRX The Vitamin C 23 Serum. Formulated with an impressive 23% Pure Vitamin C (L-Ascorbic Acid), this potent dark spot corrector works effectively to fade hyperpigmentation, brighten dull skin tone, and improve overall skin texture. Infused with Super Vitamin E and Hyaluronic Acid, this antioxidant-rich serum protects your skin from environmental damage while delivering deep hydration and a visible, healthy glow.

Key Features

• High-Concentration Pure Vitamin C (23%): Targets stubborn dark spots, acne scars, and uneven skin tone for a dramatically brighter and clearer appearance.
• Powerful Antioxidant Synergy: Enriched with Super Vitamin E (Tocotrienol) which works up to 50 times more effectively than Tocopherol to boost the skin's defense against aging.
• Intensive Brightening & Firming: Not only brightens but also stimulates collagen synthesis to help improve skin elasticity and reduce the look of fine lines.
• Allantoin Soothing Effect: Formulated with Allantoin to soothe and protect the skin from potential irritation commonly associated with high-potency Vitamin C.
• Freshness Guaranteed: Features a specialized oil-layer top to prevent oxidation and maintain the potency of the pure Vitamin C until the very last drop.

How to Use

After cleansing, during the serum phase, shake the bottle lightly 1-2 times from side to side. Apply a few drops to the skin and gently massage with your fingertips in circular motions until absorbed. Important: If using in the morning, always follow with a broad-spectrum sunscreen (SPF 30 or higher) to protect your skin from UV-induced sensitivity.

*Note: A slight tingling sensation is normal due to the high concentration of pure Vitamin C. For first-time users, we recommend a patch test.
