Niacinamide is a form of vitamin B3 and is one of the most versatile ingredients found in modern skincare products.
Topical niacinamide can support the skin barrier and may help improve the appearance of uneven skin tone, enlarged-looking pores, excess oiliness, and redness.
It can be particularly useful for people looking for one ingredient that addresses several common skincare concerns.
However, stronger does not always mean better. High-concentration niacinamide products may cause irritation in some people, while lower concentrations can still provide useful skincare benefits.
A good skincare routine is not about choosing the highest percentage available. It is about finding a well-formulated product that your skin can tolerate consistently.
