Review: Cosiq serum - 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.
Review: Great niacinamide serum - 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
