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

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.

I have bought this serum multiple times because it truly works wonders for my skin! The Ordinary Niacinamide 10% + Zinc 1% has significantly improved my skin's texture, reduced redness, and helped control excess oil and breakouts. It feels lightweight, absorbs quickly, and doesn't leave any sticky residue. For such an affordable price, the quality and results are unbeatable. I will definitely keep repurchasing it!

This is a very good quality product for how cheap it is , very suprised . It comes in a glass bottle with a dropper that works fine , it’s really liquidy so it comes out the dropper pretty fast , it’s also sticky a gooey which for me personally don’t have a problem with that but I know for some people it is. When I apply it on my skin it’s cooling and it’s a bit hard to blend in since it’s like liquidy & gooey but eventually it does , and doesn’t feel heavy on the skin and gives a glow . So since I have very sensitive dry rosacea and eczema skin I only put about a pea size amount on my both cheeks, nose , chin , and forehead I don’t put a lot but it does a big difference in my skin . I notice my cheeks were a lot less red and I believe it’s because of the zinc. I tried a lot of nicamide products they always irritate my skin immediately but this never did . Not only did it calm my rosacea a bit it also smooth my skin a lot , I’m not acne prone or break out a lot but I notice my skin is more smooth , sometimes your skin just needs to be exfoliated gently and this works . Also my skin is glowy so that’s amazing . My pores do look smaller as well . Overall a great product and recommend.

I have very acne prone skin and oily skin. To be honest in the beggining it did sting but after a while the stinging went away after 2 weeks. I applied twice a day morning and night!! My skin did look overall more healthier and gave me a nice glow which i like and my skin started clearing up after a month! I use it with my tretinion but currently im only using it in the morning so my skin isn't irritated later on. I would say this is something im going to be investing more into i already went through 5 bottles!! But keep this in mind, you don't need this. lots of hydrating or skin repair serums and creams already have niacinamide! Dont want everyone to spend there money on a product that contains something that they already have( more common than you think)●0●!!🗣🤍. So other than that it really is there for more additional help more than anything. But if u feel like u can benefit from it go right ahead 🫶

i’ve been using this for almost a year now and i can say, this stuff has been my holy grail as someone with bangs and a t-zone that produces enough oil to deep fry a whole chicken every hour or so. it’s not even something i’ve had to apply regularly to see results, it literally worked on the first try and works every time i have applied it since then. i’m sure there are other benefits you can get out of this if you allow it time to build up just like you would most other skincare products, but for me, if i decide on tuesday I don’t want an oily forehead, i can apply some in the morning and i won’t have an oily forehead on tuesday. it delays the greasy sheen I get by like 8-12 hours (as mentioned above, i’d be ready for a dabbing tissue within 1-2 hours after the last one). idk what magic is in this stuff but it works. it does make my skin oddly shiny but I just apply it under my bangs so it doesn’t bother me. I think it’s because it tightens up the skin, closes the pores. i prolly need to wear it on my cheeks too, hm. but man idk how i ever managed without it. ‘tis a new staple in my bathroom. like, if the apocalypse ever comes i’ll be sure my first purchase is a few dozen bottles of this stuff. the world may be ending but at least my bangs won’t be greasy. niacinamide be preserving this stylish fringe since november 2025 and will be for the rest of time. don’t sleep on it. get u some now

The oil glands in my t-zone still think I"m 13 but this serum does help in making it less oily. Most effective thing I've tried and the price is great. I also love, love, love the glass container!

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’ve been using this for a few weeks and I really like it so far. My skin feels smoother, looks more even, and I’ve noticed less oil throughout the day. A little goes a long way, although using too much can make it feel sticky. No strong smell either, which I like. Definitely worth the price and I’ll be purchasing it again!

تحفة لاحظت توحد والغمقان راح بجد يستاهل

Creo que si es original, es buen producto y me ha ayudado a manejar mis imperfecciones/problemas de acné. Es cierto que tiene mal olor, pero investigue y eso es lo que se espera con este producto, ya que no buscan que huela bien, solo quieren que funcione para lo que es y evitar alguna reacción alérgica por productos que lo hagan "atractivo". Su consistencia, también corresponde al producto original, según mi investigación, al principio puede que parezca que tiene grumos, pero una ves que lo aplicas ya no tiene esa consistencia grumosa. Y el envase, de igual manera, puede que se sienta barato, pero según es lo que ellos buscan, un producto de buena calidad envasado en un envase -vaya la redundancia- económico pero suficiente para mantener el producto bien almacenado, todo esto para mantener un precio asequible.

Tres satisfait

Better than minimalist I've been using The Ordinary Niacinamide 10% + Zinc 1% for several weeks, and it's become a staple in my skincare routine. The lightweight, water-based formula absorbs quickly without feeling sticky and layers well under moisturizer and sunscreen. It has noticeably helped reduce excess oil, improved overall skin texture, and gradually faded post-acne marks with consistent use. Pros: - Lightweight, non-greasy formula - Helps control excess oil and shine - Gradually reduces the appearance of acne marks and uneven skin tone - Improves skin texture with regular use - Fragrance-free and suitable for most skin types - A little goes a long way, making the bottle last - Excellent value for the quality Cons: - Results take a few weeks of consistent use. - May cause mild irritation if used with too many active ingredients at once. - Can pill if too much product is applied or layered improperly. - Not a replacement for a dedicated moisturizer. Verdict: If you're looking for an affordable serum to help manage oily skin, reduce the appearance of blemishes, and improve overall skin texture, The Ordinary Niacinamide 10% + Zinc 1% is a great choice. Be patient and use it consistently, along with a good moisturizer and sunscreen during the day, for the best results.
