This Neutrogena Stubborn Blackheads Daily Acne Facial Serum works great & works amazingly fast! I noticed a difference within 3 days of using it. My pores are less clogged & visibly look better. I’ve had less breakouts & the texture of my skin has gotten a lot smoother. I use it daily, to prevent more blackheads. Like that it has effective ingredients for acne prone skin. It doesn’t have a fragrance so it’s great for sensitive skin too. Packaging is great too- so easy to apply! Highly recommend!
