COSRX The Vitamin C 13 Serum 20ml

Product Description:

If your skin looks dull, uneven, or marked by dark spots, a well-formulated pure vitamin C serum is a proven way to bring back brightness and glow. This COSRX vitamin C serum pairs a mid-strength 13% pure vitamin C with soothing and hydrating ingredients to help brighten the look of skin and even the appearance of tone, while staying gentle enough for many sensitive-skin users. It has a lightweight, water-based texture that absorbs quickly without stickiness.

What makes this vitamin C serum a lovely entry point into pure vitamin C is its balanced, supportive formula. A 13% concentration of pure vitamin C is joined by a stable vitamin C derivative and niacinamide to help brighten and even the look of tone, glutathione for antioxidant support, and super-vitamin E (tocotrienols) to boost antioxidant support, with hyaluronic acid, panthenol, and allantoin to hydrate and soothe. The result is a fresh, glowy finish from a mid-strength vitamin C that is gentler than a high-percentage formula.

This serum suits most skin types, including sensitive skin, and is an especially nice fit for dull, uneven, or dark-spot-prone skin that wants gentle brightening. Apply a few drops after cleansing, morning or evening, and always follow with sunscreen in the daytime. A couple of honest notes: pure vitamin C can tingle on sensitive skin, so patch test and introduce it slowly, and it is best kept refrigerated and used within a couple of months of opening, since pure vitamin C oxidises over time.
