20% Niacinamide Face Serum for Clear, Glowing Skin, 30ml

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!

I’ve tried a lot of niacinamide serums over the years, and this one is easily one of the best. The texture is lightweight, absorbs quickly, and doesn’t feel sticky or heavy at all — perfect for layering under moisturizer or makeup. After about 2 weeks of daily use, I noticed my skin looked smoother, brighter, and more even. My pores appear smaller, redness has gone down, and my skin just looks healthier overall. I also love that it’s hydrating without making my skin oily. No irritation, no breakouts (and my skin is sensitive), just consistent results. A little goes a long way, and for the price, this is an absolute steal. I’ve already added it to my daily routine and will definitely be repurchasing. Highly recommend if you’re looking to improve texture, tone, and clarity

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 used the COSIQ Vitamin B3 (20% Niacinamide) serum and I really like it. The texture is light and it absorbs quickly into the skin. It does not feel sticky or heavy.My skin feels smoother and more hydrated after using it.It works well in both morning and night routine. It contains Niacinamide , peptide and hyaluronic acid which improves your skin and makes your skin healthy.

This Vitamin B3 (Niacinamide) serum is a solid daily skincare product. The texture is smooth, non-sticky, and layers well under moisturizer and sunscreen. I noticed better oil control and a more refined skin texture within a couple of weeks. It helped calm small breakouts and made my skin look healthier overall. No strong fragrance, which I really appreciate. A good affordable option for anyone dealing with pores, uneven tone, or mild acne.

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

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 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.
