Enlarged pores, a shiny T-zone and recurring impurities? The COSRX The Niacinamide 15 Serum is COSRX's strongest answer to them. With 15 % niacinamide and zinc PCA, it regulates excess sebum, visibly refines the appearance of pores and soothes redness – according to the manufacturer, with up to 50 % less sebum production after four weeks. Acetyl glucosamine enhances the brightening effect and fades acne marks, while allantoin and trehalose soothe the skin and supply it with moisture. The light texture absorbs quickly, with no sticky feeling at all – fragrance-free, oil-free and silicone-free.
