A potent 23% vitamin C serum that delivers intense brightening and antioxidant protection, visibly reducing dark spots and dullness.
The Vitamin C 23 serum 20ml
The Vitamin C 23 serum 20ml
Best suited to skin already used to vitamin C, since this is COSRX's higher strength option at 23% pure ascorbic acid. Start every other day and build up as tolerated. Follow with moisturizer and SPF since fresh vitamin C can make skin more sun sensitive.

Description
The Vitamin C 23 Serum is a high strength brightening treatment built around 23% pure ascorbic acid, along with a stabilized vitamin C derivative, niacinamide, and vitamin E, aimed at dullness, uneven tone, and early signs of photoaging. The anhydrous, water free base helps the vitamin C stay stable and potent for longer than water based formulas.
The texture is dense and slightly tacky at first but absorbs fully, leaving skin looking brighter and prepped for moisturizer. Because of the strength, it is best suited to skin already used to vitamin C.
Apply a small amount to cleansed skin in the morning after toner, then follow with moisturizer and SPF. Start every other day and build up as tolerated.
