Our take on the Good Molecules Niacinamide Serum

A lightweight facial serum built around 10% niacinamide (vitamin B3), aimed at evening out skin tone, refining texture and making pores look smaller. It is a simple, single-active formula rather than a multi-ingredient treatment, so it suits people who want one targeted step and can layer it with other products. Compared with rivals, the 10% strength sits in the middle of the niacinamide range: stronger than gentle 5% serums, milder than 20% formulas that can irritate. Reviewers rate it highly overall, praising the texture and value, while some report irritation or see little change.
