Review: Best product ever tried for Face Serum - 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
Review: Just a normal serum! - 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.

### ⭐⭐⭐⭐⭐ Review
*by A***A on 3 January 2026*

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.
