What are the benefits of niacinamide?

Niacinamide (vitamin B3) is a versatile ingredient that reduces enlarged pores, controls sebum production, fades hyperpigmentation, strengthens the skin barrier by boosting ceramide synthesis, reduces redness and blotchiness, and has mild anti-aging properties. It is one of the most well-tolerated active ingredients across all skin types. Studies support its efficacy at concentrations as low as 2% and up to 10%.
