What the science says
Niacinamide has some evidence of helping fade dark spots and patches, and it did better than a moisturizer without it, with skin also looking lighter as spots faded 1. For acne, niacinamide has some evidence of helping, and it often worked about as well as clindamycin, though some research found the results uncertain 2. Most of the acne studies pointed the same way, so the picture is encouraging but not conclusive 2.
