Cos-IQ 20% Niacinamide Face Serum For Clear Glowing Skin, Bright Skin, Reduces Dullness, Hydrates & Repairs Skin with Vit B3 & Hyaluronic Acid for Targets Acne Marks | For Women & Men | 30ml

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.

Lightweight niacinamide serum that absorbs fast and feels non-sticky. Helps control oil, calm acne, and gradually fade dark spots while improving overall skin texture—great for daily use, especially for oily or acne-prone skin.
