About
What it is.
Niacinamide 10% + Zinc 1% is a water-based facial serum from The Ordinary, part of the brand's core actives lineup built around single-concentration formulations rather than blended proprietary complexes. Niacinamide (vitamin B3) is paired with zinc PCA, an ingredient combination commonly used to address oil production and the appearance of blemishes.
It fits a no-frills skincare routine: apply and go, no layering rituals or specialized tools required. The formula suits people managing breakouts or uneven texture who want an ingredient-led option rather than a heavily marketed treatment product, and who are working from The Ordinary's broader system of targeted, single-purpose serums.
The verdict
The Ordinary Niacinamide 10% + Zinc 1% ranks as the top niacinamide serum by AI panels and earns 4.7/5 stars from over 231,000 buyers who praise its affordability and acne-fighting efficacy, though some users report irritation or find the texture too thin for their needs.

Frequently asked
What buyers want to know.
Does this serum really work for acne?
Buyers rate its effectiveness for acne and breakouts at 4.6 out of 5, and over 231,000 owners report visible results. The combination of niacinamide and zinc is designed to address oil production and the appearance of blemishes.
What's the main downside?
Some buyers experience irritation or sensitivity (rated 4.3/5), and others find the texture too thin for their skin type. It's a water-based serum, so it won't work as an occlusive or heavy moisturizer.
Is it worth the price?
Buyers consistently rate value for money at 4.7 out of 5. The combination of low cost and proven acne efficacy makes it a strong price-to-performance choice, with no cheaper competitor matching its track record across this many reviews.
Who should buy this?
It fits people managing breakouts or uneven texture who want a straightforward, ingredient-led serum without marketing hype. It also suits buyers who want effective acne control on a tight budget and those who prefer simple routines with no layering rituals.
How easy is it to use?
Buyers rate texture and absorption at 4.5 out of 5, meaning it applies easily and dries down without fuss. It fits a no-setup routine—apply and go—and works as a standalone serum in any basic skincare step.
Is this a complete skincare solution?
No. It's a single-purpose serum focused on acne and oil control, part of The Ordinary's system of targeted serums rather than a multi-benefit treatment. You'll need a cleanser, moisturizer, and sunscreen to round out your routine.
