What the science says
Niacinamide has some evidence for helping acne, with most studies finding it worked about as well as clindamycin when applied to the skin 1. All four studies that tested it directly found it faded dark spots and patches, a finding that has some evidence behind it 2. Two studies on aging found it improved firmness and reduced wrinkles, and that evidence is some evidence too 3. For the skin barrier, the evidence is not proven yet, since only one study has tested it and found less water loss 4.
