What the science says
Niacinamide has some evidence behind fading dark spots, as all four studies that tested it directly saw patches improve and skin look lighter 1. Acne research has some evidence too: most studies found benefit, often matching clindamycin applied to the skin, though some results were uncertain 2. Anti-aging findings also have some evidence, with studies reporting firmer, more elastic skin and fewer wrinkles 3. The skin barrier finding is not proven yet, resting on a single study that showed less water loss 4.
