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

Affordable and effective! I’ve relied on this product for years (I'm talking 5+), and it lasts about a month with twice-daily use. While it does cause a bit of redness around my nose and face, it delivers that coveted glass skin look and actively helps reduce acne, scarring, and even out overall skin tone. I start my day by applying it right after washing my face, then seal it with CeraVe moisturizer that leaves my skin soft and smooth. A word of caution: avoid applying it daily around the delicate eye area, as it can cause some peeling. Want to prevent this? Just layer a hydrating toner (I’m From Rice Toner is fabulous) before applying your serum and moisturizer. This hydration sandwich creates a barrier that works wonders, helping eliminate peeling around your eyes. I only do this at night. The redness from the serum can be covered with makeup if you'd like, but if you’re a no-makeup girl, I recommend using it only at night for the best results.

I've been using The Ordinary Niacinamide 10% + Zinc 1% for a while now, and it has honestly become a must-have for my daily routine. What I love most is how it keeps my skin's oil in check-I've noticed my forehead is less shiny, giving me more of a healthy glow rather than an oily mess. It's been incredible for smoothing out my skin texture and making my pores look a lot more refined. Since I started applying it twice a day, my skin feels so much more radiant and hydrated. Another huge benefit is how it helps with the occasional breakout; if I feel a pimple coming on, I use this as a spot treatment at night, and it usually starts shrinking much faster than if I did nothing at all. Plus, at around $6.00, it is easily the most affordable and effective way I've found to keep my complexion looking clear and consistent.

This is an awesome product for my daughter's teen acne prone skin. The combination of niacinamide and zinc helped control infections and tames redness/recent scares. We tried other brands but none worked like this with the zinc combo. Also, my daughter doesn't have much patience so she likes that the serum is easy to apply and absorbs quickly. It doesn't discolor bed sheets like other acne products. We have bought this multiple times already. Last but not least, the price is pretty amazing!

Okay I haven’t found a product as good as this. This product has been nothing but good to me. I suffer with very oily skin that is prone to breakout. I wake up in the morning and use this and do my skincare at night and use this. My dark circles have brightened, my skins oily is basically gone, it doesn’t irritate my skin and I have such sensitive skin. My face doesn’t feel like it’s “squeaky clean” like it usually does, this has helped my skin dryness too. Other products I’ve used just stripped away the natural oils in my skin. This doesn’t! This is so effective and yes, to my girlies (or guys) with oily skin, BUY THIS! It has helped me so much on my skincare journey and I guarantee it will also help you!!!! ALSO, a recommendation, when you apply ur cleanser and you vitamin C, let all of that sit for at least 10-15 minutes before using the serum. If you don’t the serum will be all soapy when you go to put it on, ALSO RECOMMEND getting a Jade roller for your face which will help the application process go much smoother! I hope this helps!!!!

The Ordinary’s Niacinamide 10% + Zinc 1% is a popular skincare serum that targets blemishes, uneven texture, excess oil, and enlarged pores. Niacinamide (vitamin B3) helps regulate sebum production, improve clarity, and refine the look of skin texture, while zinc supports a calmer, balanced complexion. This formula has a lightweight, water-based texture that absorbs quickly without feeling sticky or heavy. It layers well under moisturizers and sunscreen, making it easy to include in both morning and evening routines. Many users notice reduced shine and smoother skin appearance after consistent use over several weeks. It’s especially suited for oily or combination skin, though those with dryness can also benefit if they pair it with a good moisturizer. Because it’s a concentrated active, it’s best introduced gradually—especially if you’re new to niacinamide—to avoid potential sensitivity. Pros: ✔ Helps control oil and minimize the appearance of pores ✔ Lightweight, fast-absorbing formula ✔ Works well under other skincare products ✔ Great value for a high concentration serum Cons: ✖ Results take a few weeks to build ✖ May be slightly irritating for very sensitive skin ✖ Not a direct acne treatment (best combined with other actives) Overall: A versatile and effective everyday serum that supports smoother texture and more balanced skin, especially for oilier complexions.

I’ve been using this consistently and it has helped balance my skin and reduce excess oil. The texture is lightweight, absorbs quickly, and layers well with moisturizer and sunscreen. I’ve noticed my pores look less visible and my skin feels smoother overall. No irritation and easy to add into any routine. Great affordable option.

I purchased this product a couple of days ago and applied the serum that same night. By morning, my skin looked smooth, light, and non-greasy. The serum also controlled shine throughout the day, especially in my T-zone (amazing!!). Additionally, I noticed a visible reduction in pore size around my chin, nose, and cheeks. It really feels good waking up in the morning seeing much improvement on your skin. The serum pairs well with the Beauty of Joseon Green Plum toner I use beforehand, and works well w my moisturizer and sunscreen too.

2週間ほど夜のみ使用していますが、毛穴が引き締まった気がします。 濃度が高いため他の美容液との併用を避けています。（夜はこちら、朝はビタミンC） 混合肌なので、指に2滴取ってTゾーンを中心に馴染ませていますが、粘度が高くて少量でもかなり伸びが良いので数あるナイアシンアミド美容液の中でもコスパ最強だと思います。 使用初日は指に余ったものを頬に伸ばしたら部分的に少しピリつきを感じましたが、2日目からは大丈夫でした。乾燥する感じもありません。 ただ皆さんがレビューしているように、擦るとモロモロめっちゃ出ます。あまり擦らないように薄く伸ばす程度に塗れば問題なし。 クリーム・オイルインタイプの油分が入ったミスト化粧水が好きでよく使うのですが、ナイアシンアミドは親水性なのでミスト化粧水を使う時は洗顔後すぐにこちらを塗っています。 まだ2週間なのでざらつき改善やトーンアップ効果は感じていませんが、コスパも良いので続けてみる価値はあるかなと思います。

Very good for oily acne prone skin

Best

I love this product as it gets rid of redness on the skin and smoothens the skin Great value for money and easy application

Llevo 2 meses usando el producto y mi rostro se ve y siente mucho mejor. Tengo piel de mixta a grasa, por lo que se me resecaba mucho en la frente, costados de la nariz y barbilla. También tenía muchas marcas de acné. Usando esta niacinamida el problema de resequedad mejoró y desapareció; mi piel se ve tersa e iluminada. Las marcas de acné las fue desvaneciendo en unas 3 a 4 semanas de uso. Yo seguí las instrucciones al pie de la letra, y mis rutina de piel de la mañana y noche ya solo tienen 3 productos (este y un suero hidratante en la noche, y protector solar en la mañana) A mí me funcionó usar 4 gotas en el rostro y 4 en el cuello, poniendo primero 2 y luego las otras 2, dejando absorber entre aplicaciones. También me enfoqué en las marcas de acné El bote dura exactamente un mes aplicando de esta forma. No tiene olor ni deja alguna textura o sensación grasosa.
