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. Product Details Brand: COSRX Product Type: High-Potency Vitamin C Serum Weight: 20g (0.70 oz.)
