I’ve been using this niacinamide serum for a while and I can see a difference. My skin looks more balanced, pores appear smaller, and overall tone is more even. The texture is light and absorbs quickly without stickiness. Works well in my routine.
This is honestly one of the best serums I’ve ever used. The formula is very well made — it absorbs quickly, doesn’t feel sticky, and layers perfectly with the rest of my skincare routine. After using it, my skin looks brighter, smoother, and has a beautiful healthy shine. The glow is noticeable without making my face oily. Even though it contains 15% niacinamide, I experienced no irritation at all — no redness, burning, or breakouts. Because of the high concentration, I personally use it 2–3 times a week, and that works perfectly for my skin. With this frequency, I get great results while keeping my skin comfortable and balanced.
I love this serum! it works great on any skin, my skin type is normal to dry, sensitive , and has some pimples. My age is 42. This serum helps with some inflammation and redness immediately, skin becomes much cleaner and healthy looking just in a few days if using this serum! will by again!!
Great product to use Visible changes in my open pores . Non scented. High quality ingredient. Size is adequate u can use for like 3 months as I use it thrice a week . Package is handy . Skin is much better after using this . Highly recommended
Clean package. 30 ml is the decent size. I have combination oily skin. This is my first time using niacinamide. Since my skin isn't sensitive, I directly chose the 15% concentration. I can obviously feel that it controls oil production, which is the biggest benefit to me. I'm very happy.
I placed my order quickly and efficiently. I’m a loyal customer of this site and I’m now waiting for my package. However, it would be nice if iHerb also offered some product samples.
Thave read many reviews & had heard a lot about this brand. All the reviews are positive & the products seems to be really good & effective. Its not expensive & worth trying.
I’ve only used this a few times, but I can already tell it helps brighten my skin and even out my tone. The texture is lightweight and absorbs quickly without feeling sticky. It has no noticeable scent, which I really like since it doesn’t interfere with other products I use. I’m looking forward to seeing more long-term results with regular use. It feels gentle and effective, perfect for adding to a daily skincare routine.
I’m an experienced niacinamide user, and my skin usually tolerates it well, so I decided to try this 15% serum — quite a high concentration. After over a month of daily use, I can’t say I’ve noticed much change in pigmentation or pore size. The glow is definitely there, though. Recently, I started combining it with their 345 Relief Cream, and that was a real game changer! Honestly, I’m not sure this serum is even necessary — the cream alone seems to do a fantastic job. The serum itself is watery and lightweight, very economical to use — I still have about two-thirds of the bottle left. I’ll keep using it, but for such a high niacinamide percentage, the formula doesn’t seem particularly effective. One big plus, though, is the packaging: a thick glass bottle that looks like a little perfume — very elegant on the shelf.
I don’t think I’ve seen improvement or benefit from using just one bottle, great side is there is no irritation and no scent too. I like packaging is minimal and nice design.
