Removal of Self Inflicted Scars

Hi i have approx 10 year old self injury scars. Just would like an opinion on whether anything can be done eg fraxel laser to help the appearance of these. I am very scared of making them worse, and not sure whether to accept and move on rather than risk making them worse. I have scars on my arm and both legs also, I guess though it is only my arm which causes a problem. Would really appreciate any help as very down on myself for having made the mistake early on in my life..
