What the science says
Niacinamide has some evidence for fading dark spots: all four studies that tested it directly found it helped, and it beat a plain moisturizer without it 1. For acne, most studies found it helped, and it often worked about as well as clindamycin applied to the skin, though this also has some evidence 2. Its anti-aging support has some evidence too, with both direct studies showing firmer skin and fewer wrinkles, but only two studies tested this 3. Skin barrier benefits are not proven yet, since just one study tested it directly and found less water loss 4.
