Niacinamide

What the ingredient tells you
Niacinamide is a form of vitamin B3 used in skincare. Research and educational sources describe potential benefits for moisture support and the appearance of uneven tone. Those benefits depend on the finished product; an internal ingredient rating cannot establish zero irritation.
Using the finished product
Follow product directions and avoid adding several new products at once. A higher percentage or more bottles containing niacinamide is not automatically better.
Compatibility and tolerance
Niacinamide may be included in routines with other ingredients, but this does not establish universal compatibility. It can cause side effects in some people; the entire formula and your response matter.
