Cos-IQ 20% Niacinamide Face Serum For Clear Glowing Skin, Bright Skin, Reduces Dullness, Hydrates & Repairs Skin with Vit B3 & Hyaluronic Acid for Targets Acne Marks | For Women & Men | 30ml

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

This Vitamin B3 face serum has a lightweight and non-sticky texture. It spreads easily and absorbs well into the skin. With regular use, skin feels smoother and looks more balanced. Nice quality product for daily skincare use

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.

I’ve been using this 10% niacinamide serum daily and I really like the results. It’s lightweight, non-sticky, and absorbs quickly into the skin. With regular use, my skin feels brighter, smoother, and more hydrated — and I’ve noticed my pores look a bit smaller too. Great affordable serum for everyday use.” �

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.

Nothing happens but to use for makeup purpose is ok

Honestly this is a good-quality niacinamide serum at a reasonable price. It’s gentle, effective and works well for daily use—especially for oily, acne-prone and combination skin. I’ll definitely continue using it ❤️…. I’ll definitely recommend this🥳

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.
