What the science says
Niacinamide has some evidence for fading dark spots, as all four studies that tested it directly found it helped 1. For acne, it has some evidence, with most studies finding it helped and often working about as well as clindamycin applied to the skin 2. Studies on signs of aging also show some evidence, with skin looking firmer and fewer wrinkles in the two studies that tested it 3. For the skin barrier, the evidence is not proven yet, since just one study tested it and found less water loss through the skin 4.
