Introduction

With many years of experience testing blemish-control serums to find the best face serum for dry skin, I know how hard it is to find a product that stops oil without completely drying out your face. I bought this little bottle of The Ordinary Niacinamide 10% + Zinc 1% because it is arguably the most famous cheap skincare product on the internet right now. I have personally tested and researched this wildly popular serum to see if its high-strength blend actually minimizes pores and controls shine during a long day. My goal here is to give you a completely honest, no-nonsense look at my experience so you can make a confident purchase decision.

Pros & Cons

Who Should Buy This

This serum is a fantastic fit for anyone with oily, combination, or acne-prone skin who desperately wants to stop looking shiny by noon. If your pores look huge and constantly clogged, the addition of Zinc PCA in this formula acts like a vacuum for excess sebum. It works perfectly for shoppers on a tight budget who want an aggressive, targeted treatment for texture issues without paying Sephora prices.

However, if you have very dry, sensitive, or highly reactive skin, you should proceed with caution. A 10% concentration of niacinamide is actually quite high; many dermatologists recommend starting with 2% or 5%. If you slap this strong formula onto a compromised skin barrier, it will likely sting and cause a temporary breakout (purging). You should also avoid it if you hate serums that feel a bit sticky before they dry down.

Technical Specifications

Our Testing Experience

First Impressions

The packaging is exactly what you expect from The Ordinary—a clinical, frosted glass bottle with a simple dropper. When I pulled the pipette out, the liquid was a bit cloudy and slightly thicker than water, almost like a very thin gel. It has absolutely no added fragrance, though there is a very faint, chemical smell from the raw ingredients. I patted three drops onto my face. It felt cooling at first, but within ten seconds, my skin felt noticeably tacky and tight as it dried.

Daily Use

I kept this right by my bathroom sink and started using it just in the mornings to control my daily oil production. I quickly realized that less is more with this product. If I used four or five drops, it would inevitably pill up into little white balls when I tried to apply my sunscreen over it. Once I scaled back to just two drops applied to slightly damp skin, the pilling completely stopped. It really needs a good moisturizer layered on top to get rid of that tacky finish.

Key Features in Action

The oil-controlling power of the 1% Zinc PCA is the real star here. Usually, my T-zone is an oil slick by 2:00 PM, but using this kept my forehead almost completely matte until I got home from work. The 10% niacinamide also did exactly what it promised regarding texture. Any small, red bumps from old breakouts seemed to flatten out and fade much faster than they normally do.

Long-Term Performance

After testing this consistently for four weeks, the pores on my nose look visibly smaller and much cleaner. I rarely deal with those annoying mid-day shine emergencies anymore. While it didn’t cure my hormonal acne overnight, the overall smoothness and clarity of my skin have drastically improved. I plan to keep buying this simply because it is the cheapest, most effective oil control I have ever used.

How It Compares

Side-by-Side Comparison

In my opinion, this The Ordinary serum stands out because it offers an aggressive, highly effective treatment for oily skin at a price that literally anyone can afford. Paula’s Choice is arguably a better, more elegant formulation for fading dark spots, but it costs over a hundred dollars. Good Molecules offers a very similar 10% niacinamide serum that is much less sticky, but it lacks the Zinc PCA that makes The Ordinary so good at stopping oil. The Ordinary gives you raw, clinical pore control for five bucks.
