What Is Niacinamide?

Niacinamide is a form of vitamin B3. It is one of the most widely used skincare ingredients because it helps improve the look of enlarged pores, uneven tone and dullness, helps balance oiliness and supports a comfortable-feeling skin barrier.

Who It Suits

Almost every skin type. Oily and combination skin like it for pores and shine, dull or uneven skin for tone, and many sensitive skins tolerate it well at lower strengths.

Choosing a Niacinamide Serum Strength

  • 2–5%: a gentle everyday level, common in moisturizers and toners
  • 5–10%: typical for serums focused on tone and pores
  • Above 10%: higher-strength serums; introduce them slowly

Where to Use It in Your Routine

Niacinamide works in any step: a cleanser, toner pads, a serum or a moisturizer. One or two niacinamide products is plenty. Use it morning or evening and finish with sunscreen in the day.

Good Pairings

Tranexamic acid and vitamin C for tone, zinc or BHA for oily skin, and ceramides or panthenol for dry skin.

Frequently Asked Questions

Can I use niacinamide with vitamin C?

Yes. The two are often used in the same routine, and some serums combine them.

Can niacinamide cause irritation?

Most people tolerate it well. High strengths can feel tingly on sensitive skin, so start lower if that happens.

How long before I notice a difference?

Most people use it daily for several weeks before judging changes in tone or pores.
