I'm 20 years old. I have several very deep chicken pox scars on my forehead. I got chicken pox when I was 2 years old. After 2 laser treatments 4 years ago and injections 2 years ago, it is still very noticeable. In January 2017, I got injection too. The results were better, but I am still not satisfied. Can excision gives better results? The two big scars in the middle of my forehead are the one I hate the most.
