20% Niacinamide Face Serum with Vit B3 & Hyaluronic Acid 30ml - Clear Glowing Skin, Bright Skin, Reduces Dullness, Hydrates & Repairs, Reduces Acne Marks, Pore Shrinker Formula

I purchased this for my wife, as she really love this brand CosIQ from India and she says this is the best Face Serum ever

It does improve pores, but doesn`t lighten dark spots as it claims. You can buy a better product for the same price. Not worth the hype.

I’ve been using the COSIQ Vitamin B3 20% Face Serum for a few weeks and I’m really impressed with the results. The texture is lightweight, absorbs quickly, and doesn’t feel sticky on the skin. I’ve noticed my pores look smaller and my skin feels smoother overall. It also helped calm some redness and reduced oiliness without making my skin dry. A great option if you’re dealing with acne marks, uneven skin tone, or enlarged pores. Definitely worth trying!

The Cos‑IQ 20% Niacinamide Face Serum is a good serum for oily and acne-prone skin. It feels lightweight and absorbs quickly without making the skin sticky. After regular use, skin feels smoother and more hydrated, and it may help reduce acne marks and dullness gradually. Overall, it is a good skincare product for daily use if you want brighter and clearer skin.

Using this seum from last one month ... mstt lightweight serum h non sticky .... meri skin k according bht Acha work kr rha h ye 😍

Very disappointing delivery experience. The COS-IQ 20% Niacinamide serum arrived late and the packaging was damaged. The product box looked tampered with, which raised concerns about quality and authenticity. Expected much better service.

I’ve been using this COSIQ Vitamin B3–20% Face Serum for a couple of weeks now, and I’m honestly loving it. I was a little nervous about the 20% niacinamide at first, but it didn’t irritate my skin at all (which is a big win for me). My skin feels smoother, my pores look smaller, and the dark spots I had from old breakouts are already starting to fade. It also helps control oil, so I’m way less shiny by the end of the day. It’s got peptides and hyaluronic acid too, so it keeps my skin feeling plump and hydrated.it even helped calm down a few pimples. What I like: • Super smooth texture • Clears up skin and fades dark spots • Doesn’t dry me out or cause breakouts • Just overall makes my skin look healthier If you’re thinking about trying it, go for it! Just maybe do a patch test if you’ve got really sensitive skin. I’m definitely going to keep this in my routine.
