I have been using the Cos-IQ 10% Niacinamide Serum for a few weeks now, and the results are honestly impressive. I’ve struggled with an oily T-zone and stubborn acne marks for a long time, and this serum has made a visible difference. What I loved: • Oil Control: It significantly reduces the greasiness on my face throughout the day. My skin stays matte without feeling stripped or dry. • Effective Formula: The combination of 10% Niacinamide with Peptides and Hyaluronic Acid is genius. It doesn’t just target spots; it actually makes my skin feel plumper and more hydrated. • Texture: It has a lightweight, gel-like consistency that absorbs almost instantly. It doesn't feel sticky at all, which makes it perfect for layering under moisturizer or sunscreen. • Clean Ingredients: I love that it’s fragrance-free and avoids "nasties" like silicones, parabens, and sulfates. My sensitive skin didn't react or break out at all.

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.

Lightweight niacinamide serum that absorbs fast and feels non-sticky. Helps control oil, calm acne, and gradually fade dark spots while improving overall skin texture—great for daily use, especially for oily or acne-prone skin.

Nothing happens but to use for makeup purpose is ok

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.

Cosiq Vitamin B3 Face Serum feels lightweight and absorbs quickly without stickiness. With regular use, it helps control oil, smoothen skin texture, and give a healthy glow. My skin looked calmer and more balanced over time. It didn’t break me out, which I loved. A good everyday niacinamide serum, especially for beginners and budget-friendly routines.

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

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.
