What the science says
Niacinamide has some evidence for fading dark spots, and all four studies that tested it directly found the patches looked lighter 1. For acne, niacinamide has some evidence of helping, and it often worked about as well as clindamycin on the skin, though some studies were uncertain 2. Its anti-aging support also has some evidence, with studies linking it to firmer skin and fewer wrinkles 3. For the skin barrier, the evidence is thin: one study found less water loss, but the benefit is not proven yet 4.
