Why It Scores 9.0 — And The Label Line Behind Each Number
Effective concentration (matched to evidence)
30% of score10% niacinamide sits right at the top of the studied ~5-10% sweet spot (Bissett 2005 got results at 5%), so it earns near-full marks — effective for tone, oil and pores without chasing a needless higher number. Loses a fraction only because 10% is a touch strong for the most reactive skin.
Barrier-supporting formula
25% of score1% zinc PCA adds real sebum/blemish support, and the base is fragrance-free and oil-free — a barrier-respecting formula. Held back from top marks by the absence of hyaluronic acid, ceramides or other cushioning soothers beyond the zinc.
Tolerability + real-world response
20% of scoreGenerally well tolerated and fragrance-free, layering cleanly with other actives including vitamin C. Small deductions for the 10% strength being slightly much for very sensitive skin and the water-based texture's pilling tendency.
Value (cost per ml / per course)

Marketing Claims Vs. Reality
Contains 10% niacinamide and 1% zinc PCA.
The 10% niacinamide + 1% zinc PCA composition is stated on the label and matches the product's documented formula — the exact actives and percentages are disclosed, which is the transparency the category is scored on.
High-strength vitamin and mineral blemish formula.
The brand's 'high-strength' framing overstates it: 10% is a moderate, sensible strength, not a high one. The clinical work (Bissett 2005 at 5%, Draelos 2006 at 2%) shows moderate concentrations are what deliver results, so '10%' is effective but not 'high-strength' in any meaningful clinical sense.
Reduces the appearance of blemishes and balances visible sebum activity.
Niacinamide and zinc have real oil-support evidence — Draelos 2006 showed 2% topical niacinamide cut facial sebum excretion — so the sebum-balancing direction is supported. But the specific blemish-reduction claim is a manufacturer marketing statement for this finished product, not a result from a trial on this serum.
Fragrance-free and oil-free.
The fragrance-free, oil-free, water-based description is consistent with the disclosed formula and the brand's published INCI — a barrier-respecting base, which is exactly what a niacinamide serum should be.
What Our Test Actually Found
The correct default — 10% is the right strength, not the biggest number
The whole guide argues against buying niacinamide on the percentage, and this pick is the proof: 10% sits at the top of the clinically sensible range (Bissett 2005 got real tone, redness and line improvements at just 5%), so it works on oil, tone and pores without the irritation risk that 12-15% serums invite. It's the strength most people should actually use.
The zinc is the quiet differentiator
1% zinc PCA is a genuine sebum/blemish-support bonus that most single-ingredient niacinamide serums skip. For oily or blemish-prone skin, that pairing is why The Ordinary edges out otherwise-similar picks like the Inkey List (#3), which swaps zinc for hyaluronic acid instead.
Unbeatable value — the price everything else is measured against
At roughly $0.23/ml this is the cheapest genuinely-good niacinamide serum on the shelf. Under the guide's quality-over-price rule it doesn't win on price alone — it wins because it's well-formulated AND cheap, which is a rare combination. It's the reference product every rival is implicitly trying to beat.
Watch the pilling — apply to damp skin
The one real texture quirk: the water-based solution can pill or 'roll' if you layer it over silicone-heavy primers or moisturizers. The fix is simple — apply to slightly damp skin, let it fully absorb before the next layer. Do that and the finish is clean under sunscreen or makeup.
Sensitive skin should start slow
Ten percent is well tolerated for most, but it's a touch strong for the most reactive skin. If you sting or flush, start every other day and build up — the barrier-supporting benefit of niacinamide is undercut if you push a strength your skin is fighting.

Ten percent niacinamide at the sensible strength, 1% zinc PCA for oil and blemishes, fragrance-free and oil-free, at roughly $7 for 30 ml — the cheapest genuinely-good niacinamide serum on the shelf and the product every rival is implicitly trying to beat. Apply to slightly damp skin to avoid pilling and start once daily. Most people never need to spend more.
The Ordinary Niacinamide 10% + Zinc 1% is the value benchmark the entire niacinamide category is measured against. It puts 10% niacinamide — the top of the clinically sensible ~5-10% range — alongside 1% zinc PCA for sebum and blemish support, in a fragrance-free, oil-free, water-based serum that costs about the price of a coffee. Ten percent is the right strength: high enough to work on tone, oil and the look of pores, not so high it courts the irritation that 12-15% serums invite. The 1% zinc is a genuine bonus most single-ingredient serums skip, and the fragrance-free base is exactly what niacinamide's barrier-supporting job wants. The one real quirk is texture — the water-based solution can pill if layered over silicone-heavy products, so it goes on slightly damp skin. For most buyers this is the whole decision.
The value benchmark — the right first niacinamide serum for almost everyone.
If you want one niacinamide serum and don't want to overthink it, this is the answer and has been for years. Ten percent is the right strength — high enough to work on oil, tone and pores, not so high it courts irritation — and the 1% zinc PCA is a real bonus for blemish-prone skin that most rivals skip. It's fragrance-free, it costs about the price of a coffee, and it's the product every other serum on this page is implicitly trying to beat. Apply it to slightly damp skin to avoid pilling, start once daily, and build from there. The only buyers who should look elsewhere are the very reactive (start slower or choose a gentler booster like Paula's Choice #2) and those who specifically want a luxe, antioxidant-loaded formula. For everyone else, it's the value benchmark for a reason — and ignore anyone who tells you it can't share a routine with vitamin C.

Quick Answers
Is 10% niacinamide strong enough, or should I get a higher percentage?
Ten percent is plenty — and going higher is not better. The clinical research that made niacinamide famous used modest strengths (Bissett 2005 at 5%, Draelos 2006 at 2%), so 10% sits at the top of the sensible range. Climbing to 12% or 15% buys no proven extra benefit and raises the chance of stinging or flushing. This 10% + zinc formula is the right strength for almost everyone.
Why does it pill or roll off my skin?
That's the water-based texture reacting with what's underneath it, usually a silicone-heavy primer or moisturizer. Apply it to slightly damp skin, use a small amount, and let it fully absorb before your next layer. Done that way it sits cleanly under sunscreen and makeup.
Can I use it with vitamin C?
Yes. The old 'never mix niacinamide with vitamin C' warning comes from decades-old raw-ingredient and heat conditions, not finished modern serums. In real formulas they're perfectly fine layered together — one of the picks on this page (Paula's Choice #2) literally puts both in one bottle.
Morning or night?
Either, or both. Niacinamide is one of the best-tolerated actives there is and works AM or PM. Start once daily to let your skin adjust, then move to twice daily if you like. Always follow with sunscreen in the morning.

In a 12-week double-blind, split-face study, 5% topical niacinamide applied twice daily significantly reduced fine lines, hyperpigmented spots, red blotchiness and sallowness versus vehicle — the anchor evidence that a moderate concentration works, which is why this 10% serum's sensible strength is rewarded over higher-number rivals.
