Received this product on 4th Jan in good condition. The pump packaging is convenient and hygienic. The serum feels light, non-greasy, and blends easily into the skin. After using it consistently, my skin feels smoother and more balanced. Didn’t cause any breakouts. Overall, a nice addition to my skincare routine.

I’ve been using this Cos-IQ Vitamin B3 10% face serum consistently for a few weeks now, and it’s honestly one of the best budget niacinamide serums I’ve tried! The lightweight, non-greasy texture absorbs easily into my skin without leaving any sticky residue, making it perfect for both morning and night routines. It's fragrance free and easy to apply. Right from the first week, I noticed my complexion looking more even and brighter — dark spots and minor acne marks seemed to fade gradually with regular use. Many other reviewers also mention visible glow and softer skin texture after using this serum. What I really like is how it controls oil and minimizes the look of pores without irritating sensitive areas — it feels gentle yet effective. The added peptides and hyaluronic acid help keep my skin hydrated and smooth, so my face looks healthy and refreshed. At this price point CosIQ provides a good quantity of the product.

I have always preffered to use a strong niacinamide serum as i have a very oily acne prone skin and this product is so good. It makes the redness go away in no time and takes away oiliness and acne in a few weeks. You can also use it for anti ageing purposes as it comes with multi peptides. The consistency is very watery and light weight. Definitely give this a try if you're struggling with acne and do pair it with a ceramide moisturizer.

I had high hopes for this product but it's just average. It does what it's supposed to and the quality isn't bad at all! It has no scent which is perfect. It's super soothing on my skin and I have combination skin. But it is super sticky after drying, which i hate. Also the pump packaging sucks for a serum. The quality of the packaging is okayish. It's cheap so I'm okay with it

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.

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.
