What the science says
Niacinamide has some evidence for fading dark spots, with all four direct tests finding it helped 1. Aging signs show some evidence too: both direct studies reported firmer, more elastic skin and fewer wrinkles 2. Acne results carry some evidence: most studies found niacinamide helped, and it often matched clindamycin applied to skin 3. Skin barrier benefits are not proven yet, as only one direct study found lower water loss through the skin 4.
