Niacinamide Serum

Niacinamide is a form of vitamin B3 used widely in leave-on skincare. Serums in this range often combine it with zinc, alpha arbutin or tranexamic acid, and several listings are described for oily skin or for dark spots.

Comparing strengths

Niacinamide serums are usually labelled with a percentage, and higher is not automatically better — lower concentrations are often chosen for sensitive skin. Compare the stated percentage alongside price per millilitre.
