These scars are approximately 9 years old. It was something I did in high school and no longer do. They're white, fairly flat and don't seem to be going away anytime soon. I tried one treatment of fraxel laser, I know we're supposed to get around 5 treatments, but it's expensive and I don't want to do it if it doesn't work. The scar still looks the same as the others. Is there another treatment that might be better for them? Or would a tattoo be more effective?
