who should not buy it ✿
If your skin is dry or sensitive, the high concentration can feel tacky or trigger flushing. This is not a hydrator, so do not buy it expecting to skip your moisturiser.

I am suspicious of any skincare product that costs less than a sandwich. So I read the reviews carefully, and the verdict is simple: at $12 this does exactly what it says, and nothing it does not.
What niacinamide is actually for
Niacinamide is a form of vitamin B3 that reviewers reach for to help manage oil, the look of enlarged pores, and general blemish-prone skin. Dermatologists note it is one of the better-tolerated actives, which is part of why this bottle has gathered more than 18,500 reviews without the price ever climbing.
The 10 percent concentration here is on the strong side. Owners with oily and combination skin are the happiest, reporting a calmer, less shiny complexion over a few weeks. It is a treatment, not a moisturiser, and the reviewers who understood that going in are the ones who rate it well.
What owners report across the reviews
what owners praise ✿
- + Twelve dollars for a serum that lasts months, so the cost per use is negligible
- + Owners with oily and combination skin report less shine and calmer breakouts
- + A well-tolerated active that dermatologists consider low-risk for most skin
- + One clear job, no vague promises about doing everything
what owners complain about ✿
- − The 10 percent strength can feel sticky or pill under other products
- − Reviewers with dry or sensitive skin report flushing or irritation
- − It treats, it does not hydrate, so you still need a moisturiser
- − The dropper packaging feels cheap and can be fiddly
The recurring complaint is texture and the odd reaction, usually from people with drier or more reactive skin who found 10 percent too strong. That is a fit problem, not a quality problem. Layered correctly on the right skin type, the results owners describe are consistent for the price.
The verdict
If you have oily or blemish-prone skin and you want a targeted active without spending $60, this is close to an automatic recommendation. At $12 the downside is tiny and the upside, for the right skin, is real.
Skip it if your skin runs dry or sensitive, where a gentler, lower concentration will serve you better. Buy it knowing it is a specialist tool, not an all-rounder, and you will likely be glad you did.
The bottom line
A cheap, single-purpose serum that does one thing well for oily and blemish-prone skin, as long as you know what that one thing is.
