If dullness, uneven tone, visible pores or a shiny T-zone are on your mind, niacinamide is the multitasker your routine will thank you for. This clever form of vitamin B3 is loved for brightening the look of dark spots, evening out skin tone, refining the appearance of pores and helping balance excess oil, all while supporting a healthier-looking moisture barrier. K-beauty formulas pair it beautifully with hydrating, soothing and brightening ingredients for a clearer finish without irritation. Our edit brings together the best niacinamide essences, toners, serums, ampoules and creams.
