COSRX – The Vitamin C 23 Serum

Description

This high-potency serum contains a clinical-grade concentration of 23% Pure Vitamin C (L-Ascorbic Acid). It is designed to aggressively target hyperpigmentation and brighten the complexion while providing powerful antioxidant protection. To maximize the effectiveness of the Vitamin C, the formula includes Tocotrienol (Super Vitamin E), which has a higher antioxidant capacity than standard Vitamin E, and Glutathione. Because pure Vitamin C is notoriously unstable, this serum is formulated in an oil-and-water “bi-phase” structure to prevent rapid oxidation. It also contains Allantoin and Squalane to soothe and moisturize, helping to mitigate the tingling sensation common with high-strength acids.
