I love the CP Serum. I would say that I noticed results in about 3-5 days. I put on my jojoba oil at night, wait about 10 minutes, then put on the CP Serum. It has faded all my old marks. My skin is smoother and I don't think I have been getting new acne as much. In fact, I know I haven't. I do use the exfol serum in the morning, same routine with the jojoba oil. I would recommend it to any one. Good luck.
