COSRX The Vitamin C 23 Serum

COSRX The Vitamin C 23 Serum is a powerful glow serum that boosts brightness and smooths dull areas with a concentrated dose of pure vitamin C. Its silky, quick-absorbing texture leaves the skin fresh, hydrated, and naturally luminous. Enhanced with hyaluronic acid and nourishing antioxidants, it brings clarity and radiance to your daily routine. Paired with the COSRX The Retinol 0.5 Oil from Meandskin, it creates a perfectly balanced day-to-night ritual — brightening by day, refining by night — for a soft, vibrant complexion that feels full of life.

After cleansing, lightly shake the bottle once or twice.
Apply a few drops evenly to your face, avoiding the eye area.
Gently pat with fingertips to help absorption.
Begin using 2–3 times per week, then increase as your skin adjusts.
Always follow with sunscreen during the day for best results.
