Best Niacinamide Serums for Oily Skin of 2026

If two months of a 10% serum hasn't moved your shine, this is the step up we take: 12% niacinamide with 2% zinc PCA, a full point more zinc than the Ordinary's formula and the highest zinc dose stated on this list.

What we appreciate is that the extra strength doesn't arrive with a heavier feel. It's a silky, fragrance-free fluid — the label asks for one or two pea-sized drops for the whole face — and it sinks in fast enough that sunscreen can follow immediately.

It's also a narrower formula than Anua's, with nothing aimed at the marks old breakouts leave behind. That's the trade at 12%: you're buying oil and pore control rather than fading. If marks are the complaint, the money belongs in a different bottle on this list.

Good Molecules sells its niacinamide serum as a two-pack of 30 ml bottles, which says something about how it expects to be used: daily, morning and night, without rationing. That's 60 ml in total, and it works out cheaper per bottle than almost anything else here.

The formula is short and unfragranced, and the pH of 7.1 is the detail we care about most. It sits close to skin's own, so this doesn't fight the acid toner you use on alternate nights and doesn't need a waiting period before the next step. It's light, absorbs quickly, and skips the slippery finish that makes some 10% serums hard to layer.

Our reservation is the format. You're committing to 60 ml of a formula you haven't tried yet, and if it doesn't suit you, that's a lot of bottle to work through. If you already know 10% niacinamide agrees with you, it's simply two bottles of a good thing at a good price.

Oil is rarely the only thing going on with oily skin — there's usually a trail of dark marks from old breakouts too, and that's the job this one takes on. Ten percent niacinamide sits alongside 4% tranexamic acid and 2% arbutin, the most complete mark-fading lineup on this list.

Ceramides and hyaluronic acid keep it comfortable rather than clinical, and it's fragrance-free, which matters on a face that flares at scent. A drop or two covers the whole face, so a bottle lasts longer than the 1.01 ounces suggests.

The trade-off worth knowing before you order is the finish: it dries tacky. Not unbearable, but enough that we keep this one for the evening and put something weightless on in the morning. Used at night, the tack stops mattering and the formula gets to do the job you bought it for.

3.38 fluid ounces doesn't sound exciting until you've priced niacinamide serums by the bottle: this is more than three times the usual 30 ml, and it's the most product for the money on this list. That changes how you use it — you can be generous on your neck and chest without watching the level drop.

The formula pairs niacinamide with tranexamic acid and Madagascar centella asiatica, and the centella is what places it: it's the calming ingredient in the bottle, aimed at skin that is oily and easily annoyed at the same time. There are small capsules suspended in the ampoule that break down as you spread it — pleasant, but not the reason to buy.

Skin1004 doesn't publish a niacinamide percentage, so treat this as the soothing end of the list rather than a strength upgrade. You're buying it for the centella, the volume, and the fact that a reactive face is less likely to argue with it than with a 12% formula.

Not everyone can wear 10% niacinamide, and most people who can't find out the hard way. This is the bottle for them: 5% niacinamide with 1% hyaluronic acid and aloe, at a price that makes the experiment a small one.

It's fragrance-free and made without silicones, sulfates, parabens, essential oils or dyes — a lot of exclusions for a serum this inexpensive. The texture is thin and watery and sinks in without residue, which is the right call for something you'll layer under moisturizer.

We keep this one in mind for a specific situation: skin that's already irritated, whether from retinol, a bad week or over-exfoliating, and still wants niacinamide in the routine. It's also the bottle we suggest to someone who has never used an active, because starting here tells you whether niacinamide agrees with you without costing you a week of sting.

A pH of 5.5 to 6.5 is the detail that places this one in a routine: it sits where skin likes to be, so it doesn't undo the acid toner from ten minutes ago and it doesn't need a wait before the next step.

The oil control is more specific than most. Ten percent niacinamide comes with a dual zinc complex — zinc PCA and zinc glycinate — plus Matmarine, a marine extract aimed at sebum and shine. It's fragrance-free, non-comedogenic, and light rather than syrupy.

On paper this is the most oil-focused serum here: two forms of zinc for sebum and a marine extract for shine. If your complaint is the sheen on your nose by three in the afternoon, that's a more specific answer than a straight 10% formula.

So the decision is clean. If your issue is shine by mid-afternoon and the look of your pores, this does that job for less than almost anything else here, and it layers without drama. It's the oil-control specialist on a list of generalists.

This is the one scented formula on the list, and it isn't subtle — closer to a light perfume than to nothing. That's the first thing to know, because on a face that reacts to fragrance, no concentration of niacinamide makes up for it.

What's in the bottle is generous: 12% niacinamide with zinc PCA, hyaluronic acid and ceramides, in a 2-ounce bottle that's roughly double the standard 30 ml. If you go through serum quickly and use it on your neck as well as your face, that size is the argument.

The texture is the part we like best. It goes on smooth, absorbs without leaving grease, and leaves skin feeling soft rather than tight — a combination that's harder to find at 12% than it should be.

So buy it if you want the most serum for the money and scent doesn't bother you, and skip it if your skin has ever stung at a fragrance. Naturium runs the same 12% concentration without the perfume, in a smaller bottle.
