If one ingredient earns its place in almost everyone's routine, it's niacinamide. This form of vitamin B3 is the quiet multitasker of Korean skincare — loved for helping skin look more even, refined and comfortable, and for playing nicely with just about everything else on your shelf. It suits most skin types, oily and sensitive included. Every niacinamide formula in the EE-MO line-up, in one place.
