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

I’ve been using this serum consistently and I’ve noticed my skin looks smoother and more balanced. It helps control excess oil, reduces the appearance of pores, and leaves my skin feeling soft without being greasy. It absorbs quickly and works well with the rest of my skincare routine. Great value for the price!

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 !

The lightweight, water-based formula is one of the things that makes this serum easy to work into a skincare routine. With 10% niacinamide and 1% Zinc PCA, it focuses on several everyday skin concerns without turning the routine into a complicated process. I also appreciate that the product information is clear about what the serum can and cannot do. It specifically explains that it isn’t an acne treatment, while noting that it can be used alongside acne treatments. The directions are straightforward as well, with just a few drops recommended in the morning and evening. The focus on hydration, radiance, smoother-looking skin, and supporting the skin barrier makes this feel like a practical addition for someone looking to improve the overall appearance of their skin rather than expecting an overnight transformation. I also liked that the clinical information gives a clearer idea of the timeframe for the reported results, including barrier hydration and smoother-looking skin. A simple formula, clear directions, and an easy-to-understand purpose make this a convenient serum to add to a regular skincare routine.

I’m really happy with The Ordinary Niacinamide 10% + Zinc 1%. I started using it as part of my skincare routine, and I’ve noticed a big improvement in the appearance of my skin. My complexion looks smoother, more balanced, and healthier. The serum is lightweight, absorbs well, and doesn’t leave my skin feeling heavy or greasy. I like that it’s simple and easy to use, and the results have been great for me. I’m very satisfied with this product and would definitely buy it again.

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 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.

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.

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.

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".
