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

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!

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.

Very disappointing delivery experience. The COS-IQ 20% Niacinamide serum arrived late and the packaging was damaged. The product box looked tampered with, which raised concerns about quality and authenticity. Expected much better service.

The COSIQ Vitamin B3 niacinamide serum fits really well into a daily routine. Lightweight texture, absorbs quickly, and doesn’t leave the skin sticky. Been noticing a more balanced and clearer look with regular use. Simple, effective, and easy to layer with other products.

Great product
