Niacinamide is a form of vitamin B3 and one of the most versatile ingredients in skincare. It is water-soluble, gentle for most skin types and plays well with other ingredients.
What it helps with
the look of enlarged pores and shine in the T-zone;
uneven-looking tone and post-blemish marks;
a comfortable, resilient-feeling skin barrier.
Which percentage?
2–5% is a comfortable everyday range; most people do not need more. Higher percentages are not automatically better and can feel tingly on sensitive skin.
How to use it
Morning, evening or both, after toner and before moisturizer. It sits well under sunscreen and makeup.
Good partners
Hyaluronic acid for hydration, ceramides for comfort, zinc PCA for oily skin. The old advice about not mixing niacinamide with vitamin C comes from older, less stable formulas; modern formulas can be layered, but if you notice flushing, use them at different times of day.
