- Some studies found 4% niacinamide cleared acne about as well as clindamycin

On Reddit: Vitamin C and niacinamide together brighten uneven skin tone on the face while feeling hydrating and fragrant. 14 mentions
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
