You are still young and your metabolism is relatively fast. When you have acne, it will disappear after a while. Your skin has the ability to repair itself, and acne marks will slowly disappear. I suggest you not use anything. Let me tell you a diet therapy. From now on, no meat, no big oil, all vegetarian and light. It will help your acne. Stick to it for a month and it will work, my child.
You are too young to use acne cosmetics. Not so good.
