My hubby has the same problem. He scars badly and easily. he also had a bad acne problem when he was younger that I suspect wasn't just an acne problem. It seems that some skin types just really have a bad time with leaving marks, either pigment or white lines after injury. Does anyone in your family get keloids? Maybe your docotr can talk to you about how to handle inflamations when they get started, but at any rate, see if you can talk to someone who is a specialist in skin problems.
