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. These studies observed changes in how pigment is transferred to skin cells. While this evidence is strong, most trials involved small groups of participants, which limits how broadly these findings can be applied to all skin types.
- Minimizes poresModerate evidence
- Niacinamide
Randomized human trials involving 50 participants measured changes in sebum production and pore appearance after applying 2% niacinamide. 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.
