Description

COSRX The Vitamin C 23 Serum is a high-strength brightening serum formulated with 23% pure vitamin C, Super Vitamin E, and glutathione. It helps improve the appearance of dullness, uneven skin tone, dark spots, post-breakout marks, and early signs of aging while leaving skin looking more radiant and refreshed.

How to Use

After cleansing and toning, apply 2–3 drops to the entire face and gently pat until absorbed. Follow with moisturizer and SPF during the day. Because of its high vitamin C concentration, avoid using it in the same routine as retinol, copper peptides, or other high-concentration actives.

Benefits
