What is niacinamide?

poresoil-controluneven-tonebarrier
Short answerNiacinamide is vitamin B3 used in serums and moisturizers to support the skin barrier, even tone, and the look of pores.

Who it is for

Niacinamide is a reasonable first active if you want something gentler than a strong acid or retinoid. People concerned with oiliness, the look of pores, or blotchy tone often start here.

How to add it to a routine

  1. Cleanse.
  2. Apply a niacinamide serum to damp skin.
  3. Moisturize.
  4. Use a broad-spectrum sunscreen in the morning.

You can use it with hyaluronic acid, peptides, retinoids, and most vitamin C formulas. If a high-strength product stings, drop to a lower percentage or use it every other night.

What it is not

It is not a chemical peel, not a treatment for diagnosed skin disease, and not a substitute for medical care. Ingredient pages in this knowledge base explain the research-backed uses in cosmetic products.
