Niacinamide (Vitamin B3)
A form of vitamin B3 that earns its near-ubiquity: at 2–5% it strengthens the barrier, tempers oil, calms redness, and fades post-acne marks, while playing well with almost every other active. It is one of the few ingredients with both broad clinical evidence and a very low irritation ceiling.
