What the science says
Niacinamide has some evidence for fading dark spots, with studies finding it helped patches fade better than a moisturizer without it 1. For acne, niacinamide has some evidence of helping, and it often worked about as well as clindamycin when applied to the skin 2. Its anti-aging benefits have some evidence behind them, with studies reporting firmer skin and fewer wrinkles 3. For the skin barrier, the evidence is not proven yet, since only one study tested it directly and it found less water loss through the skin 4.
