The Ordinary Niacinamide 10% + Zinc 1%, Smoothing Serum for Blemish-Prone Skin

The Ordinary Niacinamide 10% + Zinc 1% is an excellent serum. It absorbs quickly, doesn’t feel sticky, and noticeably smooths the skin. I’ve seen improvements in texture and oil control, and my skin looks healthier overall. Definitely a 100/100 product — highly recommended and worth every penny.

I have oily, combination skin with enlarged pores and I’ve been dealing with breakouts since my teenage years. I also have PCOS, which makes my skin even more oily, so I’ve tried many acne products over the years. From my experience, zinc and niacinamide really work, and this serum helps me keep my skin under control. I use it about 3–4 times a week, usually at night, after cleansing and toning. It’s one of the final steps in my routine. The texture is on the thicker side and can feel slightly sticky or pill a bit, so I prefer using it at night — that doesn’t bother me at all. What matters is the result. My skin looks noticeably better with this serum than without it. Breakouts dry out faster, heal quicker, and overall I get fewer small pimples. I don’t use it daily because my skin already experiences enough stress from dry indoor air and cold weather, so I apply a nourishing cream on top to keep my skin balanced. The serum is clear, has no noticeable scent, and I really like the dropper — it’s easy to control the amount and apply it evenly. Overall, I’m very happy with this product. It’s been a reliable part of my skincare routine.

Quality is great, and leaves your skin texture smooth and clean. With is effective and works well! This brand has yet to disappoint! Great value for your money as it works.

It worked for me really fast and I love that it cleared up any dark spots that I had and made it better, it doesn't smell or anything and it makes my face so soft smooth and hydrated I definitely will buy it again, worth the money.

The price is the best from this product is a good band for niacinamide I’ve used for a long time, skin looks bright good for sensitive skin too, no reactions.

Desperate for a solution for my oily skin (53 years) and sebaceous hyperplasia ( enlarged bumpy pores) I came across this serum looking for solutions, I tried everything even with the dermatologist treatment and nothing, I started using this and OH WOW, the difference in my skin texture, my pores, oil control and my sebaceous hyperplasia almost gone, ( this appears when is excessive sebum production) I can’t be more happy with my results. No fragrance is a plus, really easy to apply and is one of the best products I came across for my face.

Recently after a gut bacterium imbalance, my Sebum production went higher than normal and pores became visibly large and clogged skin, leading to onset of pimples on face. I was advised to use Niacinamide based serum, I started applying just after delivery of the product and on first day I faced redness and uneasiness on face. Therefore, I skipped a day and thereafter have been applying regularly before going to bed. It also stings for a few minutes application, a sensation like burning or heat. I didn’t get any new redness or uneasiness. It doesn’t feel heavy or sticky and lasts whole night. My skin has improved within a couple of days, pores are visibly smaller and didn’t get new pimples. Those having eczema or other pre-existing conditions may first consult dermatologist or go with a diluted version instead of directly opting for 10% concentration.

I’ve been using The Ordinary Niacinamide 10% + Zinc 1% consistently, and it has made a noticeable difference in my skin. If you struggle with oiliness, breakouts, or enlarged pores, this serum is definitely worth trying. The texture is lightweight and water-based, absorbs quickly, and layers well with other skincare products. It doesn’t feel greasy or heavy, which I really appreciate. After a few weeks of use, my skin looks more balanced, less shiny, and overall smoother. I’ve also noticed that it helps calm breakouts and reduce redness over time. While it’s a high concentration of niacinamide, it hasn’t irritated my skin when applied correctly (a few drops, once daily at first). Another big plus is the price. The quality you get for this cost is impressive compared to much more expensive serums that offer similar benefits.
