How do you get rid of leg scars caused by picking at scabs?

When I was younger I would just love to pick at my scabs. Now I barley get scabs and I think it’s disgusting. I really regret doing that to my self because now my legs are covered with scars. When I wear shorts I feel really self conscience. If you stand in the distance you cant really see them but if you come close you will be able to. I want to have pretty legs by the Summer time. Is that possible? I don’t mind buying anything. Please help me!
