The Ordinary Niacinamide 10% + Zinc 1% is a water-based serum that targets dullness, uneven skin texture, enlarged pores, and excess oil. With 10% niacinamide and 1% Zinc PCA, it brightens skin, refines texture, and supports a healthy moisture barrier. Apply a few drops to the entire face morning and evening before heavier creams for a visibly smoother, more radiant complexion.
