Evidence by claim
- Evens toneStrong evidence
- Niacinamide
Multiple randomized human trials have measured niacinamide’s impact on skin pigmentation and the appearance of dark patches.

While these studies observed changes in skin texture, most were funded by the industry, which can influence how results are reported. Consequently, the evidence supporting these findings is considered moderate.
