“Contains niacinamide and zinc.”
Niacinamide and zinc are both listed as the serum's actives — the pairing itself is disclosed and consistent with the product's clarifying positioning.

Glossier Super Pure is the pick for people who bounce off basic niacinamide serums because of how they feel. It pairs niacinamide with zinc for redness and blemish support in an unusually elegant, fast-absorbing gel-serum that layers invisibly under makeup. The strength is a moderate, calming level rather than a maximal one — on-brief for tolerability and exactly what the evidence supports — and the base is fragrance-free and pared-back. The catches are practical. Glossier leans direct-to-consumer and Sephora, so its Amazon listing is third-party-fulfilled and stock and price can wobble; it also costs several times more per ml than the value leaders for a comparable actives payload, and it doesn't publish its exact percentages. If elegant feel matters more than squeezing maximum value, it's worth it; if you just want the actives cheaply, the top four beat it.

Read the complete Looksmaxxing guide →Glossier positions the niacinamide at a moderate, calming level rather than a maximal one — squarely in the evidence-supported sweet spot (Bissett 2005 at 5%). It scores well on strategy but a notch below the disclosed-10% picks because the exact percentage isn't published, so it can't be scored precisely.
Niacinamide + zinc on a fragrance-free, pared-back gel base is barrier-respecting and adds sebum support. It sits below the leaders because there's no hyaluronic acid or antioxidant headline, and the actives payload is comparable to serums that cost a fraction as much.
A calming, moderate strength plus a light, fast-absorbing gel makes it one of the gentlest-feeling, most comfortable serums here — genuinely pleasant to layer and wear under makeup, and on-brief for sensitive users who hate heavy actives.
At roughly $28 for 30 ml (~$0.93/ml) it costs several times more per ml than the value leaders for a comparable actives payload — you're paying for texture and brand, which is the lowest value score among the top picks.
The gel texture and invisible layering are the best-in-class finish here, but transparency is weaker — exact percentages aren't disclosed — and stock is unreliable, which pulls the extras score back down.
“Contains niacinamide and zinc.”
Niacinamide and zinc are both listed as the serum's actives — the pairing itself is disclosed and consistent with the product's clarifying positioning.
“A specific high-strength dose of niacinamide.”
Glossier does not publish the exact niacinamide or zinc percentages for Super Pure, describing it only as a moderate, calming level. Without a disclosed number the precise concentration cannot be verified — which is a transparency gap relative to the picks that state exact percentages.
“Calms redness and reduces the look of blemishes.”
Niacinamide's barrier-calming action and zinc's sebum support make the redness/blemish direction plausible (Bissett 2005 reduced red blotchiness; Draelos 2006 cut sebum). But these are appearance-based manufacturer claims for the finished product, not measured outcomes for this serum.
“Lightweight, fragrance-free gel that absorbs quickly.”
The fragrance-free, fast-absorbing gel texture is the product's standout and is consistent with hands-on reports and the disclosed formula — genuinely the most elegant finish among the picks here.
Super Pure's reason to exist is feel: a fresh gel-serum that absorbs instantly and layers invisibly under makeup. If you've abandoned basic niacinamide serums because they felt tacky or heavy, this is the one that fixes that. The actives are sensible; the sensorial experience is the differentiator.
Glossier pitches the niacinamide at a calming, moderate level, which is exactly what the evidence supports (Bissett 2005 worked at 5%). That's the right call for tolerability. The catch is it doesn't publish the exact number, so you're trusting the positioning rather than reading a percentage.
Glossier leans direct-to-consumer and Sephora, so its Amazon listing is third-party-fulfilled — meaning stock and price can be volatile and fulfillment less predictable than a first-party listing. If reliable resupply matters to you, that's a genuine strike against it.
At roughly $0.93/ml it costs several times more than the value leaders for a comparable niacinamide + zinc payload. Under the quality-over-price rule that premium only makes sense if the texture is what you're buying — it does not buy extra efficacy, and the guide is explicit that it shouldn't outrank a better-value serum on feel alone.
For someone who wants a calming, pleasant, low-drama introduction to actives, the light gel and moderate strength make this an easy on-ramp. It's less about maximum results and more about a formula you'll actually enjoy using daily.
Super Pure is the pick for people who bounce off basic niacinamide serums because of how they feel. The niacinamide-plus-zinc combination is sensible and the moderate strength is exactly what the evidence supports, but the reason to choose it is the texture — a fresh gel-serum that absorbs instantly and layers invisibly. The catches are practical: Glossier leans direct-to-consumer, so the Amazon listing is third-party-fulfilled and stock can wobble, it doesn't disclose exact percentages, and you pay a real premium per ml for a comparable actives payload. If elegant feel matters more than squeezing maximum value, it's worth it. If you just want the actives cheaply and reliably, the top four beat it — which is why it ranks where it does.
