I've gone through more niacinamide serums than I want to admit, mostly chasing the same promise: less redness, fewer breakouts, and pores that don't look like craters by 3pm. Most of them did nothing noticeable in the first two weeks. This one was different, and it's cheap enough that I'm comfortable saying so without it sounding like a paid line.
Genuinely calming within the first week, no pilling under sunscreen, and priced low enough to try without overthinking it. Loses points only for a slightly tacky finish if you layer too much.
If your skin gets patchy-red through the day, or you deal with visible pores and occasional breakouts without full-blown acne, this sits in a good middle ground. It's not aggressive enough to irritate sensitive skin, but it's concentrated enough that you'll actually see something change — usually within 10 to 14 days of using it morning and night.
Two drops, morning and night, after cleansing and before moisturizer. I didn't change anything else in my routine for three weeks so I could actually tell if it was working — no new cleanser, no new sunscreen, nothing else added. That's the only way a review like this means anything.
If you're dealing with active cystic acne, this alone won't be enough — you'll want something with salicylic acid or a dermatologist-guided routine alongside it. And if your skin is already very dry, pair it with a heavier moisturizer, since niacinamide on its own can feel a little thin in colder months.
