Niacinamide is a form of vitamin B3 used widely in skincare as a general-purpose conditioning ingredient. It supports the skin barrier — the outer layer responsible for holding moisture in and keeping irritants out — and is commonly used for the appearance of uneven tone, visible pores and dullness. It is notably well tolerated, which is why it appears so often in products aimed at sensitive skin.
