NiacinaMax Serum With 10% Niacinamide (Vitamin B3), Tea Tree Oil, Calendula Extract, Allantoin And Vit. B5 & E - Enhanced Dermal Penetration - Shrinks Pores & Reduces Blemishes On Skin - 60 ml

Been using this for about 4 years now and can honestly say it’s made a huge difference. My pores got smaller, face got a lovely glow, and so smooth. I love it. This and the retinol one and the face pads are my go to!

Leave your skin very smooth, highly recommended it

I like that this brightens my skin, helps to maintain youthfulness, isn't heavy, in fact it is very light, and is non greasy. Easy to use, and lasts a long time. A little goes a long way.

Works quickly and reduces pore size.

When I bought this, I decided to try it because I wanted a niacinimide serum, but the one's I had tried before didn't make me think that they were really doing anything. A few years ago I used Olay Luminous and did see a brightening effect but then it seemed like the formula changed and it wasn't as strong anymore and just didn't make me look any better. Then I came across The Ordinary 10% and thought maybe I'd found the holy grail so I bought it plus abut 5 other serums that they make. I felt like all the hype over that brand wasn't really justified because I didn't see any benefits from their peptide serum, niacinimide serum, caffeine under eye serum, or retinol. And I knew I should be seeing benefits. So I decided that a lot of companies are stating 5% 10% of this or that ingredient but it just isn't. and also sadly a lot of once good brands are now making their serums (it feels like anyways) at half the concentration as when they first came out with them? After clogging my pores with 10 or 15 different brands of serums that I found on Amazon I came to be an ingredient detective and won't buy a serum anymore if the top ingredients are pore clogging. None of the ones I tried gave me any benefits anyways aside from one collagen copper cream which I really liked and was going to stick with til I began getting clogged pores from it. The other brand that I almost stuck with was Advanced Clinicals serums because there was a slight brightening from the C serum and I also used the collagen and hydroxy acid ones. But sadly again, their main carrier ingredient in those is isopropyl myristate. And it takes weeks for pores to clog so I used them for a couple months before I discovered they were now doing the opposite and wrecking my skin. I bought a niacinimide serum about 3 weeks ago and got no result and then dug out the old bottle of The Ordinary 10% and still couldn't match the brightening effect of the early version of Luminous before it changed formulas. I felt defeated because here I am reading articles about what niacinimide can do for skin, yet in the real world I'm not seeing any benefits whenever I have tried it. But I know it works, if used in 4% and above concentrations. So these companies must be using 1 or 2%? All of this brings me to this serum. I bought it because I like the ingredients looking like they won't clog pores and I like the strength of both formulas they offer. 5 and 10 percent. I decided to go right for the 10. On first application I liked the feel of it. A watery gel that sinks in and doesn't interfere with putting sunscreen or makeup over it. And no tackiness. No oiliness on application or later on. I also felt a slight tingle the first time I applied it. Not painful but more like a feeling of oxygen on my skin. I can't explain it. Almost like hydrogen peroxide applied in the ear but not as strong as that. Over the first few days I also noticed that I would get that feeling again at different times during the night if I apply it at night. Probably because I'm not putting sunscreen or anything over it to dilute it at night. I've been using it one or two times a day. The good news is that after 4 days I noticed I look healthier. My skin looks more toned and my under eyes look better. I", on day 6 now and for the past couple days I keep thinking that my skin looks brighter. Like i did with the early Luminous. But this is working better than that did, for an overall change in my skins appearance. I've been using a bit all over my body too when I get out of the shower, so I can see the brightening is everywhere and so it can't be makeup or etc. I'm also using this serum alone and no other moisturizers or treatments of any kind. So I know it is this product that's doing this. And for that reason I ordered the peptide collagen serum and the under eye serum to add to my face care routine and to see if I get any additional benefits from using those aside from what this serum is going to continue to do. I expect it to show even more benefit over time as it's only been a few days and I"m impressed with what it's beginning to do already. So as you can tell from my review, I'm very happy with the serum and QRX for making it. I feel like they're honest in their percentages and ingredients and it is showing in the results of what theyr're serum is doing, rather than what the others I"ve tried have claimed to do, but haven't. (Aside from those that did have some results but caused blocked pores in the pores which isn't a good trade off for me.)

Texture is good, smell is also good but it is not working on my acne.skin is not getting results what the serum claimed, using since last 3 weeks.

Tomei um sust quando a embalagem da Amazon chegou. O vidro nao veio em uma CAIXA ou um envólucro. Veio com plástico bolha, o que garantiu a sua integridade. A marca não se preocupa com a estética externa, mas sim com a qualidade do produto. E acreditem, ele é incrivel. Realmente, p quem tem (como eu) pele sensível, esse SÉRUM é excelente. Acalma a irritação, mantém a pele hidratada e visivelmente, a aparência de pele saudável vem com o uso contínuo. Tenho usado todos os dias, e desde então, minha pele nunca mais ficou irritada. Parabéns ao Laboratório.

Prodotto eccellente. Purtroppo non sembra che il fornitore statunitense abbia molto interesse a vendere tutta la sua gamma fuori dagli USA. Peccato!

Cada piel es distinta y hasta ahora he comprado distintas marcas de niacinamida que cuestan menos de 20€ (Revolution, The Ordinary, Le Cabinet…) y algunas se nota bastante su efecto pero, la de QRxLabs, en mi piel (mixta y reactiva) no ha hecho nada de nada (bueno, por lo menos no me ha provocado ninguna reacción alérgica en la piel lo cual es de agradecer). No repetiré
