What is it?
COSRX Advanced The Vitamin C 23 Serum is a high-potency facial serum formulated with 23% pure vitamin C (ascorbic acid) to visibly brighten the complexion and improve overall skin appearance. Its innovative dual-layer formula combines a water-based serum with a protective oil layer to help maintain the stability and effectiveness of the vitamin C.

What it does
This serum helps brighten uneven skin tone, reduce the appearance of post-acne marks, and improve the visible signs of ageing. The high concentration of pure vitamin C provides antioxidant protection against environmental stressors while supporting firmer, healthier-looking skin. Super Vitamin E (tocotrienol) and hyaluronic acid help replenish moisture, soothe the skin, and minimise dryness, leaving the complexion looking smoother, more radiant, and revitalised.

How to use
After cleansing and toning, shake the bottle gently to mix the two layers before use. Apply a few drops evenly over the face, avoiding the eye area, and gently pat the serum into the skin until fully absorbed. Follow with a moisturiser, and apply sunscreen during the day. If you are new to high-strength vitamin C, begin by using the serum two to three times a week before gradually increasing the frequency as your skin builds tolerance.

Who's it for?
This serum is suitable for most skin types, particularly those concerned with dullness, uneven skin tone, post-acne marks, and the early signs of ageing. It is best suited for users who are comfortable incorporating a high-strength vitamin C treatment into their skincare routine.
