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!

I have oily combination skin and regularly get breakouts from new products. This was recommended to me to cut down on the oil and reduce breakouts and it worked almost IMMEDIATELY! I now only moisturize at night. I put this on after freshly washing my face in the morning, wait a bit, and then put on my tinted SPF or foundation with SPF. Breakouts are rare now and the shine is significantly reduced. I'm happy with how it has helped my skin texture, too. AMAZING price for such a great product!

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.

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!!!!

I wanted to wait before writing a review so I could really see how this product performs over time — and I’m honestly blown away. The Ordinary Niacinamide + Zinc Smoothing Serum noticeably improves my skin texture and reduces acne almost overnight. When I use it consistently, my skin stays clear and smooth. When I stopped, I immediately started breaking out again. I used it last night and by morning my acne was basically gone. That’s how fast and effective it is for me. It absorbs well, layers nicely, and actually does what it claims. This is truly a miracle product and I’m keeping it in my skincare arsenal forever. If you struggle with texture or breakouts, this one is absolutely worth trying.

Very good for oily acne prone skin

very good

I’ve been using this serum from The Ordinary for a while now, and honestly, I’m impressed. Within a short time I started noticing a visible difference — my skin looks clearer, smoother, and much more balanced. The best part is that it’s lightweight, absorbs quickly, and doesn’t leave any greasy feeling. It worked so well for me that I recently ordered two more bottles. For the price, the results are amazing. If you're looking for something simple, effective, and affordable, this serum is definitely worth trying. Highly recommended

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.
