Review on 💧 Niacinamide + Zinc PCA Serum for Face - Pore Reducer, Skin Tone Treatment, Acne Prone Solution, Elasticity Restorer | 1 Fl Oz by Karen Lewis

Despite daily use, I didn't notice any significant improvement in fine lines or hyperpigmentation. Don't use it at night unless you want the pillow to stick to your face. I use it with my sunscreen during the day. Gives you a slightly wet look. A little more will make you look like you're smearing mayonnaise on yourself. If I saw any noticeable improvement I would buy again, but since I haven't I will return to any product I find on the shelf at Marshall's.
