When I was at school I got in with the wrong crowd of friends and started self harming. I was only doing it because I thought everyone was doing it when they weren't. i am now left with scars on my forearm. I have had them for 3 years and they are white line scars which are slightly but not significantly raised. I really want to get rid of them now and was thinking about lasers? Has anyone had laser treatment for white self harm scars? I am told CO2 laser are good?
