What the science says
For dark spots, niacinamide has some evidence, since all four studies that tested it directly found it helped fade them 1. Acne has some evidence behind it, with most studies finding niacinamide helped, though some results were uncertain 2. Anti-aging has some evidence too, as both direct studies found firmer, more elastic skin 3. For the skin barrier, the one study found less water loss, but the evidence is thin and not proven yet 4.
