Hello! I have this one scar from an awful self harm accident. It’s from October/November 2013 and is about a millimeter deep and and inch long and is on the calf of my right leg but has since healed somewhat and now looks alright but still is extremely noticeable. Any way to heal it or treat it or (last resort) hide it? Summer is coming soon and I’m so scared. I have since stopped harming myself by the way.
