What the science says
Niacinamide has some evidence for fading dark spots, as all four direct studies found it improved facial spots better than a moisturizer without it 1. Tranexamic acid has some evidence for fading melasma, with most studies reporting that dark patches became less dark and less widespread 2. For acne, niacinamide has some evidence of helping, often working about as well as clindamycin, though some results were uncertain 3. Niacinamide has some evidence for anti-aging benefits, including firmer skin and fewer wrinkles 4.
