Niacinamide (a form of vitamin B3) is a well-regarded skincare ingredient used topically for a range of concerns including uneven tone, enlarged pores, and skin barrier support. It is valued for being effective yet gentle and well tolerated.
Niacinamide has a solid evidence base among skincare actives, with research supporting benefits for skin barrier function, reducing the appearance of pores and uneven pigmentation, and general tolerability. It is one of the better-evidenced everyday skincare ingredients.
Very well tolerated by most skin types, including sensitive skin. Occasional mild irritation, usually at higher concentrations.
Rarely needed for a topical ingredient this gentle. If you have a diagnosed skin condition and are building a routine, a dermatologist can help prioritise ingredients.
Inexpensive to moderate, widely available in serums and moisturisers.
