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.

It,s a very useful serum...you must buy this Helps minimize enlarged pores and refine texture (especially with niacinamide). � ✅ Many users saw reduced acne marks and slightly brighter skin. � ✅ Lightweight, often non-sticky and quick to absorb. � ✅ Works well in routine with sunscreen/moisturizer. �

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

Awesome product.

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.

It's very effective and works great
