Niacinamide (vitamin B3) is a multi-benefit skincare ingredient known for supporting the skin barrier, balancing oil production, and improving the appearance of uneven tone.
It’s often described as a “workhorse” ingredient because it fits easily into most skincare routines and pairs well with many actives.
