Acne-prone skin
Is niacinamide good for acne? What the evidence actually says
Short answer: niacinamide (vitamin B3) is a reasonable, gentle add-on for acne-prone skin, but it isn't a first-line acne treatment. The AAD's 2024 acne guideline gives its strongest recommendations to benzoyl peroxide and topical retinoids [1]. For niacinamide, the evidence is smaller: in one 8-week trial of 76 people with moderate inflammatory acne, a 4% niacinamide gel performed about as well as 1% clindamycin gel [2], and a 2% niacinamide moisturizer reduced facial oil [3]. A 2017 review called the overall evidence limited [4]. Use it alongside a proven active, or on its own if stronger products irritate your skin.
What niacinamide does for acne-prone skin
| Effect | What studies show |
|---|---|
| Calms inflamed spots | 4% niacinamide gel twice daily performed comparably to 1% clindamycin gel on inflamed acne after 8 weeks [2] |
| Less oil and shine | 2% niacinamide lowered sebum output in a Japanese study group and surface oil in a US group [3] |
| Supports the skin barrier | Raised ceramide levels and reduced water loss in dry skin, which helps when acne treatments are drying [5] |
| Fades uneven tone | Reduced the look of hyperpigmentation in clinical testing [6]; see dark spots after acne |
Most studies are small and short, and some (including the barrier and pigmentation studies cited here [5][6]) were run by cosmetics companies. That's why we treat it as a supporting step rather than the main event [4].
How it compares with proven acne actives
| Ingredient | Best for | Evidence | Irritation |
|---|---|---|---|
| Benzoyl peroxide | Red, inflamed spots | Strong (AAD) [1] | Dryness; bleaches fabric |
| Adapalene (retinoid) | Clogged pores and prevention | Strong (AAD) [1] | Dryness and peeling early on |
| Salicylic acid | Blackheads, bumpy texture | Conditional (AAD) [1] | Stinging on sensitive skin |
| Azelaic acid | Mild acne, redness, marks | Conditional (AAD) [1] | Tingling in the first weeks |
| Niacinamide | Mild acne, oil, marks, barrier support | Small trials; limited [2][4] | Usually low; 10% can sting |
If you have more than a few spots, start with one of the stronger actives and add niacinamide for comfort and oil control. If those actives irritate you, niacinamide on its own is a gentler place to start.
How to use niacinamide
- Add one new product at a time and patch test first.
- Apply after cleansing, morning or night, then moisturize. It layers fine with benzoyl peroxide, adapalene, salicylic acid or azelaic acid.
- The acne and oil studies used 2% and 4% [2][3]. Many serums are 10%; higher isn't proven to work better, and if 10% stings, use it every other day or choose a moisturizer or sunscreen that contains it.
- Wear SPF 30+ every morning.
- Give it about 8 weeks, the length of the main acne trial [2], before judging.

A niacinamide label tells you nothing about the rest of the formula. CeraVe PM Facial Moisturizing Lotion, for example, has niacinamide fourth on its ingredient list, but it fails our acne screen because it contains cetearyl alcohol together with ceteareth-20, plus polyglyceryl-3 diisostearate, all on the Face Reality pore-clogging list. That doesn't mean it will break everyone out; our screen is deliberately conservative.
Niacinamide itself isn't on the pore-clogging lists we use (see its entry). To check a whole product, paste its ingredient list into the pore-clogging ingredient checker, or read what “non-comedogenic” really means.
When to see a dermatologist
Niacinamide won't be enough for moderate to severe acne. See a board-certified dermatologist for deep, painful or cyst-like spots, acne that leaves scars or dark marks, or breakouts that haven't improved after 2–3 months of consistent over-the-counter care. A dermatologist can offer prescription options that may work better.
FAQ
Is niacinamide good for acne?
It can help, mainly as a gentle add-on. Small trials show it calms inflamed spots and reduces oil, but the evidence is limited, and benzoyl peroxide and adapalene have stronger support.
Can I use niacinamide with benzoyl peroxide or salicylic acid?
Yes. Niacinamide layers well with benzoyl peroxide, salicylic acid, adapalene and azelaic acid. Add one new product at a time so you can tell what's working.
What percentage of niacinamide is best for acne?
The acne and oil studies used 2% and 4%. Many serums are 10%; higher isn't proven to work better, and it's more likely to sting.
Does niacinamide cause purging?
Purging is usually linked to ingredients that speed up skin-cell turnover, like retinoids and acids. Niacinamide isn't one of them, so if you get new breakouts after starting a product, stop it and check the full ingredient list.
Does niacinamide help acne scars?
It may help fade flat dark marks left after spots heal. It won't fill in pitted or indented scars; a dermatologist can discuss treatments for those.
