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

This serum has helped my acne so much ! It’s clear and doesn’t have a scent. The packaging is efficient and the dropper works very well. This serum didn’t irritate my sensitive skin which is really great ! This serum has helped me prevent so many breakouts and leaves my skin glowy and plump. Amazing for acne prone skin ! This product isn’t super expensive but it works great! The consistency is non sticky but not super thin. The residue on your fingers can be applied on your neck or chest. It doesn’t dry my skin and still gets rid of acne! I would recommend this for teens or people that struggle with acne. This serum is so worth it !

I used to have really nice skin, but ever since I started the ketovore diet 2 years ago, my face has become somewhat porous and ruddy. I don’t have acne, but I have been hating my skin texture and tone. A little research suggested that it was due to the increased fats my diet, which are causing my sebaceous glands to secrete more sebum. It suggested that I use niacinamide powder (Vitamin B3) mixed with zinc PCA in a 10% to 1% ratio by weight in distilled water to pat on my face, stating that it would calm my skin down and help with the appearance of large pores and uneven tone. Fortunately, I was able to skip breaking out the scales and doing science in my kitchen, since I found this inexpensive serum online. It is close enough in formulation to what was suggested in my research. The serum is light, non-greasy, and it glides smoothly over my skin. The size of the tiny bottle was a little disappointing, but the product is quite inexpensive and I found that a little goes a long way. The serum doesn’t take long to dry and it doesn’t feel sticky afterwards. I have used it for about a week now. It is working. My pores aren’t perfect yet, but they do look noticeably smaller. My skin seems to have calmed down a bit. It isn't quite as ruddy. I don’t find this serum particularly moisturizing, however. It seems to make my skin feel tight. Nevertheless, I’m pleased with the results.

This has easily become one of my favorite skincare products. I’ve been using it morning and night, and I’ve noticed a real improvement in my skin. My complexion looks brighter, my skin feels much smoother, and the overall texture has improved significantly. I also love that it’s lightweight, absorbs quickly, and layers well with the rest of my skincare routine without feeling sticky. I haven’t experienced any irritation, and a little goes a long way, so the bottle lasts quite a while. After consistent use, my skin looks healthier and more even-toned, and I’m genuinely impressed with the results. It’s now a staple in my daily routine, and I would absolutely recommend it to anyone looking to improve their skin’s texture and overall appearance. I will definitely keep repurchasing it.

I’ve been using The Ordinary Niacinamide 10% + Zinc 1% consistently, and it has made a noticeable difference in my skin. It helps control excess oil, reduces the appearance of blemishes, and leaves my skin looking smoother and more even. The serum is lightweight, absorbs quickly, and layers well with the rest of my skincare routine. A little goes a long way, making the bottle last a while. Definitely a great value for the price, and I’d recommend it to anyone dealing with oily or acne-prone skin.

If you want a face that’s free of blemishes and acne, hydrated, and glowing, buy this and use it every single night without fail—you’ll love it forever. I use it on my underarms too, and my 14-year-old daughter uses it constantly; it really helps with her acne. It’s truly fantastic, and the price is even more amazing... It’s not worth spending money on those super expensive creams when this one does the same thing and so much more.

I bought this as a cheaper alternative to Byomas clarifying serum. It works enough. It keeps my complexion relatively clear but doesn’t completely get rid of the blemishes or texture whereas the byoma does. The current effectiveness could have something to do with hormonal and environmental factors as well. It is a slight bit drying on my skin, I recommend only using it twice a day while your skin is still adjusting, if it starts drying out then use it once a day. The product first smells a bit weird but it doesn’t leave the smell on your skin. I’m still unsure if I will continue to repurchase this product, but after a week I am overall satisfied.

At 52, post-menopausal, with mature dry skin, I’ve tried products from every price range, from basic drugstore to luxury skincare. One thing I’ve learned is that expensive packaging and a high price tag do not automatically mean better results. This serum is one of the best examples of that. There’s a reason this product has so much attention and competition. It’s simple, affordable, and genuinely useful in a lot of routines. Niacinamide is one of the most versatile skincare ingredients out there. It’s known for helping improve the look of enlarged pores, uneven tone, dullness, excess oil, and overall skin texture while also supporting the moisture barrier. This formula pairs 10% niacinamide with zinc PCA, which is commonly used to help with visible shine and congestion. The brand markets it for brightness, smoother texture, and barrier support. This is not a miracle product. It’s a consistent-use product. You’re not going to wake up with brand new skin after one night. What you can expect with regular use is skin that looks more balanced, smoother, clearer, and healthier over time. For mature skin, niacinamide can be especially helpful because it addresses multiple concerns at once. It can help with dullness, roughness, uneven tone, and barrier support—all issues that often become more noticeable with age. The texture is lightweight and water-based, making it easy to layer into a routine. It absorbs fairly quickly, though I find best results come from using a modest amount. If too much is applied, some people notice pilling or a foamy feel, which is common feedback with this product. In terms of moisturizing, I view this as a treatment serum rather than a hydrator. It is not enough on its own for dry skin like mine, so I always follow with a moisturizer. Used that way, it fits nicely into both morning and evening routines. Another plus is fragrance. It stays focused on ingredients rather than unnecessary scent, which I appreciate in treatment products. Who is this best for? Anyone dealing with uneven texture, visible pores, dullness, blemish-prone skin, oilier skin, or anyone wanting a smart low-cost serum that can benefit many skin types. Who may not love it? Very dry or sensitive skin types may want to start slowly or choose a lower-strength niacinamide first. If you prefer rich creamy serums, this will feel more functional than luxurious. What stands out most is the value. This is the kind of product that reminds you skincare does not need to be expensive to be effective. Straightforward ingredients, fair price, and the kind of steady results that build with consistency.

I love this serum so much. I have scaring on my chest from getting shingles 5 times in my life time...I know im only 40 so that's strange but I have a lot of discoloration and using this has made a definite improvement in my coloration and uneven tones. I use it every day and it feels so smooth going on, absorbes easily, doesn't pill up. Bottle is a goid size, a little bit goes a long way. Definitely helps with hydration and I do notice a glow to my face after using for a while. I've been using it for 3 months and everyone comments on my skin. Definitely recommend because you certainly can not beat this price!

Good product

Ottimo siero viso. Avendo la pelle a tendenza acneica mi aiuta a idratare la pelle visto che uso altri prodotti prescritti dal dermatologo per la mia skin care. Ha un ottimo rapporto qualità/prezzo, visto che basta veramente una goccia per fare tutto il viso, quindi il prodotto è capace di durare un mese tranquillamente. Anzi se si preleva troppo prodotto, dopo si fa fatica ad asciugarlo e la pelle rimane un po' "unta".
