Great for controlling oil and reducing pores!
This serum works wonders! It absorbs quickly, keeps my skin balanced, and has really helped control excess oil and minimize the look of my pores. My skin feels smoother and clearer after using it consistently.

Good product
It absorbed into my skin well, didn’t leave my skin irritated and had no scent to it. High percentage of Niacinamide, which is good for aging skin.

My favorite serum
I love this serum, I have been using it for a month and I can see the difference on my skin, more bright and the dark spots are disappearing. The texture is very light for my oily skin.

Effective and Gentle on Skin
This niacinamide serum is amazing! It’s lightweight, absorbs quickly, and has noticeably reduced the appearance of my pores while keeping my skin smooth and balanced.I also appreciate that it’s gentle, no irritation or dryness, even with daily use. A definite keeper in my skincare routine!

Product for oily skin that doesn’t make it shiny
I’m a dark-skinned woman and Oh my god this is the best. I have oily skin and for years every time I tried a new product it would just make my skin oilier after a couple hours of it on my face. This doesn’t get oily after time. I only use a hypoallergenic face soap and this serum. And my acne has cleared up. Of course I have good habits like changing my sheets and pillowcases at least once a week, keeping my hair clean and keeping my hands out of my face. Pairing those habits with this little serum while exfoliating once a week has cleared up my skin, minimized blackheads and evened out my skin tone. It’s the only thing that works for me.

Love, Love, Love!!!
It works so great for my skin! It cleared my face from red pop-ups and make it feel nice and tight. I bought a few more to stock.

Quality Issue
I feel like there are quality issues with this product on Amazon. I’ve ordered the niacinamide serum a few times and a couple of times, the serums varied in consistency and scent. One time, the serum had a yellow/ brown color with an oil like consistency, and smelled heavily of perfume (normally clear and no scent). Another time, it was more watery and made me break out, when the other times I’ve ordered the product, it worked great for my skin (except for the oil-like one). Not sure what’s causing the product control issue but will likely buy from the Corsx website going forward.

good quality niacinimide
This niacinimide face serum is one of my favorites for acheiving that flawless look. I inherited my mothers large pores that, quite unfortunately, have only gotten worse with time. I did try other brands of niacinimide before this one and have settled on this being top quality. I can now happily say that, based on my pores, youd never know I was related to my own mom 😉
