Cos-IQ 20% Niacinamide Face Serum with Vit B3 & Hyaluronic Acid 30ml - Clear Glowing Skin, Bright Skin, Reduces Dullness, Hydrates & Repairs Skin, 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.

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.

Excellent quality with no skin irritation. Improves texture of the skin. Excellent value for money. Pleasant scent.

Awesome product.

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

It's very effective and works great
