What it is

Niacinamide is a form of vitamin B3 with one of the broadest evidence bases in modern skincare: it supports barrier function via ceramide synthesis, modulates sebum, reduces the look of pores, and helps even out tone over weeks of use. Typical effective concentrations range from 2% to 10%; tolerability is high across skin types.
