What the science says
Acne
Some evidence
Niacinamide: 6 studies tested it on its own. See all 17 studies
What the studies found
- Most studies found niacinamide helped acne
- Some studies found 4% niacinamide cleared acne about as well as clindamycin
- One study found 4% niacinamide improved red, sore spots, but IPL worked better
- Some research found no clear difference, and a large review said the effects were uncertain
Hyperpigmentation
Some evidence
Niacinamide: 5 studies tested it on its own. See all 24 studies
What the studies found
- All of these studies found niacinamide helped fade dark spots or patches
- In clinical trials, 5% niacinamide faded dark spots more than a placebo
- It also helped when used with salicylic acid peels, more than peels alone
- Used on its own, it helped, but one study found a niacinamide mix worked better
- One study found the fading effect reversed after stopping niacinamide
