The Ordinary Niacinamide 10% + Zinc 1% has been a fixture in skincare routines since it first launched, and heading into 2026 it’s still one of the most recommended serums for anyone dealing with oil, congestion, or the occasional breakout. At around $6-$8 for a 1 fl oz bottle, it’s cheap enough to try without much risk, but the ingredient concentration is potent enough that it’s not a throwaway product.
We spent six weeks testing it against a rotation of other niacinamide serums to see whether the hype holds up in 2026, and where it falls short. Below is our full breakdown of the formula, the application experience, and how it stacks up against newer competitors.

Design & Build
The formula itself is simple: niacinamide at 10%, zinc PCA at 1%, in a water-based vehicle with no fragrance or oil. The bottle is a straightforward glass dropper, which is functional but not spill-proof if you’re traveling. At 1 fl oz (30 ml), a single bottle lasts most people 2-3 months with twice-daily use of 3-4 drops per application. The texture is slightly tacky on application, drying down within about 90 seconds to a semi-matte finish. It layers fine under sunscreen and makeup, though we noticed some pilling when paired with silicone-heavy primers.
Performance
After 6 weeks of consistent morning and evening use, visible pore size on the T-zone dropped noticeably, and oil production by midday was down enough that we skipped blotting sheets most days. Niacinamide’s effect on hyperpigmentation showed up around week 4, with post-inflammatory marks fading maybe 15-20% faster than our control side using only a basic moisturizer. That said, the 10% concentration is high enough to cause tingling or flushing for some users, especially those layering it with actives like vitamin C or exfoliating acids. We had one tester with sensitive skin experience mild redness during week one that resolved once she cut back to once-daily use.
Pros & Cons
- Genuinely effective at reducing oil and minimizing the look of pores within 3-4 weeks
- Fragrance-free, alcohol-free formula suitable for most skin types including acne-prone
- Extremely affordable per ounce compared to prestige niacinamide serums
- Fast-absorbing and compatible with most other skincare steps
- Widely available, including multi-packs and bundles for regular users
- 10% concentration can cause tingling, flushing, or purging in sensitive or reactive skin
- Dropper bottle isn’t ideal for travel and can be messy with frequent use
- No added humectants beyond zinc, so very dry skin may need a heavier moisturizer layered on top
- Can pill under certain silicone-based sunscreens or primers
- Results plateau after about 8 weeks; it won’t address deeper texture or scarring on its own
Alternatives to Consider
If you want the same formula without repurchasing every couple of months, the Pack of 2 version saves on shipping frequency and works out to a lower cost per bottle. For those who want a gentler daily option with added hydration, the INFINITY ZONE Niacinamide 10% + Zinc 1% Face Serum blends in hyaluronic acid and vitamin B5, which softens the drying sensation some users report with the original. If breakouts are your main concern rather than dullness or oil alone, The Ordinary Oil Control Duo pairs the niacinamide serum with a sulfur-based spot treatment, which is a more targeted combination for active blemishes.
Frequently Asked Questions
Can I use this every day?
Yes, most people tolerate twice-daily use well. If you notice tingling or redness, drop to once daily for the first two weeks before building up.
Does it help with acne scarring?
It helps fade post-inflammatory redness and dark marks over time, generally 4-6 weeks, but it won’t address textured or indented scarring. For that, you’d need something like microneedling or a retinoid alongside it.
Can I layer it with vitamin C or retinol?
Niacinamide and vitamin C can be used together, though older formulations sometimes caused flushing when combined at high concentrations. With retinol, apply on alternating nights or one in the morning and one at night to avoid over-irritating the skin barrier.
Is the Pack of 2 or the Dull Skin Duo a better value?
The Pack of 2 makes sense if niacinamide alone is working for you and you just want to avoid reordering. The Dull Skin Duo, which pairs it with the Caffeine Solution 5% + EGCG, is better if dullness and under-eye puffiness are bigger concerns than oil control.
Verdict
The Ordinary Niacinamide 10% + Zinc 1% still earns its reputation in 2026. It’s not the gentlest or most luxurious serum on the market, but for the price, it delivers real, measurable improvement in oil control, pore appearance, and post-breakout marks within about a month of consistent use. Sensitive-skin users should patch test first or consider the INFINITY ZONE version for a softer entry point, but for most combination or oily skin types, this remains one of the best value actives you can add to a routine.
