I have white scars that were self inflicted about 6 years ago. I know that they are rather old, and I shouldn't have high expectations about treating them. I am mostly looking to not have them appear as self inflicted, because they are in straight consecutive lines on my forearm and thigh. They are not very raised or extremely white, just very obvious as to how they were done. What is a good treatment option for me? I've tried creams and oils, and I'm ready to move on to the next step.
