COSRX Advanced The Vitamin C 23 Serum

23% pure ascorbic acid in the updated Advanced formula.

Two-phase texture with vitamin E, hyaluronic acid, panthenol and niacinamide.

Designed for focused care of uneven-looking tone, dullness and skin texture.

Do not shake before the first opening. Attach the supplied dropper, then gently shake the bottle left and right. After cleansing, apply an appropriate amount and smooth from the centre of the face outward. Follow with the rest of your skincare; use sunscreen when applying in daytime.

Avoid using in the same application as COSRX Blue Peptide serum or cream. If using these products, separate them into morning and evening routines.

Use promptly after purchase. Store upright in a refrigerator at 3–10°C before and after opening, away from heat and direct sunlight. Use within two months after opening.

The manufacturer notes that gas, a sound when opening, intended headspace and the natural odour of fragrance-free raw ingredients may occur.
