Niacinamide

Also known as Nicotinamide, Vitamin B3

A versatile form of vitamin B3 used to support the skin barrier and improve the look of uneven tone, texture, and redness.

Vitamin / barrier-supporting active

What it is

Niacinamide, also called nicotinamide, is the amide form of vitamin B3. In topical skincare it participates in cellular processes connected with energy, barrier function, and the production of skin lipids.

Common uses and benefits

Well-formulated niacinamide products are used to support moisture retention and improve the appearance of uneven tone, fine lines, rough texture, visible pores, and blotchy redness over time. Results depend on the concentration, delivery system, supporting ingredients, and consistent use.

Who may like it

It is often chosen by people with dry, oily, combination, blemish-prone, or uneven-looking skin. Lower-strength formulas may be easier for very sensitive skin to introduce.

Common formats

  • Niacinamide
  • Nicotinamide

Pairing and use notes

Niacinamide generally pairs well with hyaluronic acid, ceramides, peptides, retinoids, and vitamin C. It can be used morning or evening according to the product directions. If a high-strength formula feels irritating, use it less often or choose a lower concentration.

Good to know

Some formulas—especially higher-strength products—can cause temporary stinging, redness, or dryness. Patch-test if you are sensitive and avoid adding several new active products at the same time.
