10% Niacinamide + Zinc Treatment Serum, 1 oz (30 ml)

Good for combo skin. I use this a few times a week and it has a nice smoothing effect. There is no scent and quality is great.

I’m a big fan of niacinamide serums because I’ve seen noticeable benefits for my skin when using them regularly. This one also contains zinc, which I think is a great addition, especially for balancing the skin. I haven’t started using this bottle yet because I’m still finishing a niacinamide serum from another brand, but I’m really looking forward to trying it. Once I start using it consistently, I’ll update my review with my results.

so far so good. I don't necessarily notice any changes, but it's not irritating to my skin and niacinamide is widely recommended, so I am giving it a shot!

I’m really enjoying the Cosmedica Skincare 10% Niacinamide + Zinc Serum. The texture is lightweight and absorbs quickly, so it layers well with the rest of my skincare routine without feeling sticky. Niacinamide is great for balancing oil, improving skin texture, and minimizing the appearance of pores, and I’ve noticed my skin looks smoother and more even after regular use. The addition of zinc helps calm the skin, which is perfect if you have occasional breakouts or irritation. The ingredients feel high quality, and the serum is gentle enough for daily use. The glass bottle and dropper packaging also make it easy to control how much product you use, and a little goes a long way, so it’s good value for the price. Overall, this is a great niacinamide serum for improving skin clarity and balance. I would definitely recommend it for anyone looking to refine pores and support healthy skin, and I would purchase again. Pros: ✔ Lightweight, fast-absorbing texture ✔ Helps balance oil and refine pores ✔ Zinc helps calm the skin ✔ High-quality ingredients ✔ Good value and easy packaging

Very good serum for balancing oily and combination skin. The texture is lightweight, absorbs quickly, and layers well with other products. After a few weeks, I noticed reduced redness and fewer breakouts. Pores appear less visible and overall skin tone looks more even.

I’ve been using this product for a while now and overall, I’m quite satisfied with it. The build quality is solid, the design is user-friendly, and it performs as expected.

The product arrived quickly and was well packaged. The quality is noticeable from the first use, and I can really feel the difference. The price is reasonable compared to the benefits it provides. I will definitely repurchase and recommend it to anyone looking for a reliable product.

Thank you very much for this product, it suited me, I like the packaging, comfortable and stylish, I will order more of these products, and recommend them to all my friends and relatives! good!!

I've added this niacinamide & zinc serum to my facial skincare routine, using it in the morning only (because I use Tretinoin at night), and while I can't know for sure exactly what impact it's having on my skin in the longer-term, it's definitely making my skin feel soft, smooth, and 'plumped'. I use it on cleansed skin, before applying moisturizer and sunscreen. It has a very faint, pleasant fragrance, applies evenly and absorbs well, without any greasiness or residue. It feels quite soothing, in fact, and my moisturizer applies nicely on top once the serum has absorbed (which happens instantly, basically). A couple of drops goes a long way, and because I'm only using it once per day, this bottle should last me a good while.
