What the science says
Niacinamide has some evidence for fading dark spots and patches, as all four direct tests found it helped 1. Studies on acne also show some evidence of benefit, often working about as well as clindamycin when applied to skin 2. Signs of aging have some evidence behind them, with studies reporting firmer skin and fewer wrinkles 3. The skin barrier finding is thin, since only one study tested it directly, so the evidence is not proven yet 4.
