A must try!
I was skeptical, especially after seeing the viscosity of this serum. It seems pretty thick, and I thought it would be too sticky. But lo and behold, it was NOT too sticky, and it absorbed quickly. As far as the effectiveness, I'd give it high marks. It immediately brightened my skin, and made it feel suuuuper soft. It worked well under primer and foundation, as well as on bare skin. I used it on my face and the backs of my hands. Skin texture improved on the first few uses. Definitely worth a try. It's effective and very affordable. I absolutely love this stuff.

less oily skin
I wanna tell you my experience about Niacinamide, which is a skincare ingredient that become more and more famous in recent years. After I used products that contain Niacinamide for a few months, I have noticed some significant improvements in my skin's appearance and texture. One of the big benefits of Niacinamide is that it helps regulate the production of sebum, which is the oil that our skin naturally produce. This is very helpful for me, because I have combination skin that tend to get oily in my T-zone. Since using Niacinamide, I have noticed that my skin is less oily overall, and I have fewer breakouts. Another benefit of Niacinamide is that it can help reduce inflammation and redness in the skin. I have some mild redness on my cheeks, and I have noticed that it has decrease since I started using Niacinamide products. I have been really impressed with the results that I have seen from using Niacinamide in my skincare routine

$12.95 for two ounce, same results, at a fraction of cost!
I was thinking of buying the Paulas choice but at $44.00 for their 0.67oz bottle I decided to look on Amazon for alternatives as I was shopping for several items and my Paulas cart was racking up at over $200 and I was not even done shopping. I was so happy to find this 10% Niacinamide+1% zinc serum with vitamin B3 for only $12.95 on Amazon AND 2 ounce to boot. I absolutely love it and am hooked on Cos De BAHA products now that I have purchased several of their line. I am pleased with the results and highly recommend these lower priced alternatives to the higher brand name items because they gave me the results I was seeking for a fraction of the cost. I’m hooked on Cos de BAHA products now and in love with their much lower prices compared to name brand items. Same results at a fraction of cost. I was able to purchase all the items I needed for less than $100 on Amazon and most products were from CosDeBAHA and even larger sizes. So happy with my purchases.

it is not the same as before
The item came pretty fast but the quality is kind of different. a year back I purchased the same but smaller version and still have bottle with some liquid left. So comparing the old and new bottle content was easy. The new one was tacky and the next day after using it my face go pinkish which normally doesn't happen. I hoped to received the same product and enjoyed it.

On My Second Bottle
I'm on my second bottle, the larger 2 ounce size. I've used it consistently for the better part of a year and my dark spots have faded. They're not gone by any means but they're noticeably lighter. This isn't a glowy, moisturizing serum but my skin isn't as dry and my pores appear more manageable. I use this in conjunction with other serums but do use it religiously twice a day over my face and neck. I'll continue to use it. Same ingredients as Glossier's version but with a lower price tag and more product.

A must-have!
I’ve been using this for about a year and I will never stop using it. My skin is smoother, softer, clearer, moisturized. I notice if I feel a pimple coming on, I put this on it at night and it’s significantly smaller in the morning. Great value! Highly recommend.

いろいろとナイアシンアミドの美容液を使ってみましたが、同じメーカーの20パーセントの物よりこちらが、私には一番合っていると思いました。 つけた時は少しべたつく気もしますが、毛穴や肌が綺麗になります。 アラ還女性です。
