COSRX The Niacinamide 15 Serum 20ml
The serum contains 15% niacinamide, a high concentration that ensures the active ingredient works as well it can for skin types that are prone to blemishes. Zinc PCA is added to the multi-benefit formula to reduce the visibility of extra oil and sebum and promote a more matted yet glowing finish. Allantoin keeps the skin hydrated, and acetylglucosamine helps to gently exfoliate the face to reveal a renewed complexion.
