What the science says
Niacinamide has some evidence for fading dark spots, with all four studies that tested it directly finding it helped 1. For acne, most studies found it helped, often about as well as clindamycin applied to the skin, though this has some evidence behind it 2. For signs of aging, the two direct studies found better firmness and fewer wrinkles, a finding with some evidence behind it 3. The single study on the skin barrier found less water loss, but that finding is not proven yet, so the evidence is thin 4.
