The Ordinary Niacinamide 10% + Zinc 1% is one of the best-selling serums on earth, largely because it costs about $6–8 and promises to tackle oiliness, congestion, and the look of enlarged pores. That combination of price and popularity invites suspicion — can a serum this cheap do anything real? Here is a clear-eyed review of what it does and does not deliver.
What the two ingredients do
Niacinamide (vitamin B3) at 10% is the workhorse: it is well researched for supporting the skin barrier, calming redness, balancing the look of oil, and interrupting pigment transfer over time. Zinc PCA at 1% is an oil-regulating and soothing addition often chosen for skin that runs shiny or congested. Note that 10% is a fairly high niacinamide level — effective for many, but the point at which a minority start to feel irritation.
Texture and the pilling issue
It is a lightweight, slightly viscous serum. Used correctly — a few drops on clean skin, patted in and given time — it absorbs fine. Its reputation for pilling usually comes from applying too much or layering it under heavy silicones too quickly. Less product and a short wait solves most complaints.
Who it suits
Oily, combination, and congestion-prone skin are the core audience. If shine control, a smoother-looking surface, and gradually more even tone are your goals, this is aimed squarely at you. Dry and sensitive skin can use it but should start slowly; the high niacinamide level occasionally causes flushing in reactive users. It is fragrance-free and vegan.
How to use it
Apply once or twice daily to clean skin before heavier creams. Start once a day to gauge tolerance. It layers under sunscreen in the morning and moisturiser at night. Give any oil-balancing or tone benefit several weeks — this is a slow, cumulative ingredient, not an instant fix.

Honest limits
At this price the value is outstanding, but keep expectations grounded. Pores cannot be physically shrunk; the serum makes them look less prominent by managing oil and improving surface smoothness. It is also not an acne medication — it supports clearer-looking skin but will not replace targeted treatment for persistent breakouts. Used sensibly, though, it is a genuinely useful staple.
Getting the application right
This serum’s mixed reviews often come down to how it is used. The formula is slightly viscous, so a little goes a long way: two or three drops for the whole face, patted in and given a minute before the next step. Layering it immediately under thick, silicone-rich products or applying too much is what triggers the notorious pilling. Applied thinly on clean skin, it behaves. If you have very dry skin, follow promptly with a ceramide moisturiser, since niacinamide is best supported by a well-hydrated barrier.
What to realistically expect week by week
Give it time. In the first two weeks you may simply notice skin feels balanced and less shiny by afternoon. Around weeks four to eight, congestion-prone skin often looks smoother and pores appear less prominent as oil steadies. Tone evening from the niacinamide is the slowest change, unfolding over a couple of months. None of this is dramatic, but for the price it is a meaningful, low-risk upgrade to an oily-skin routine — provided you are consistent rather than expecting overnight transformation.
FAQ
Can I use it with vitamin C?
Yes. Older worries about niacinamide “cancelling” vitamin C are largely overstated for modern formulas. If your skin is sensitive, simply use vitamin C in the morning and this serum at night to keep each step comfortable.
Why did it make my skin pill or feel sticky?
Usually too much product or layering too fast. Use two or three drops, pat gently, wait a minute before your next step, and avoid piling it under heavy occlusives immediately.
Bottom line
The Ordinary Niacinamide 10% + Zinc 1% absolutely works for what it is: an inexpensive, well-formulated serum that helps balance oil and improve the look of pores and tone over time. It is not a pore-eraser or an acne cure, and reactive skin should ease in, but as a low-cost daily staple for oily and combination skin, it remains one of the best-value serums available.
