Niacinamide is a form of vitamin B3 and one of the most versatile ingredients in skincare. It shows up in countless Korean serums, toners and creams because it works well for almost every skin type.
Why it is so popular
Niacinamide helps skin look brighter and more even-toned, minimizes the look of pores, and helps balance oil. It also supports the skin's moisture barrier, so it plays nicely with sensitive skin.
Where you will find it
Look for niacinamide in brightening serums and ampoules, toners, essences, moisturizers and some sunscreens.
Good to know
Niacinamide layers well with hyaluronic acid, centella and ceramides. Results build over time, so give it several weeks of consistent use. Patch-test any new product first.
