What is niacinamide?
Niacinamide is a water-soluble form of vitamin B3. Your skin uses it to make energy and to build ceramides, the fats that hold your skin barrier together. Applied topically, it supports that barrier, helps regulate oil and interrupts the way pigment reaches the surface.
Most products use 2–5%, which is where the research supports results with a low risk of irritation. Higher percentages are not always better.
Benefits of niacinamide for skin
Smaller-looking pores
By helping balance oil and keeping skin hydrated, niacinamide makes pores look tighter and more refined.
Less shine
Oily skin tends to look more matte and balanced with regular use.
More even tone
Niacinamide helps fade the look of dark spots and post-blemish marks, especially when paired with tranexamic acid or vitamin C.
Calmer, stronger skin
It supports the skin barrier, so skin looks less red and feels more resilient.
How to use niacinamide
- Cleanser
- Water-based serums such as hyaluronic acid
- Niacinamide serum
- Moisturizer
- SPF 30+ in the morning
Niacinamide can be used twice a day. It also works well rinse-off, in cleansers, if you want an easy way to start.
Tip: If your serum pills, give each layer 30–60 seconds to absorb before applying the next.
