I have scars that aren't raised from sh and they are long but not very deep, I've had them for years. If it bothers you a lot you can get surgery that removes scars. I'm looking to get scar removal on my stretch marks but not my sh scars because my scars are a reminder of what I've came through and I shouldn't be embarrassed that I struggled at certain points in my life. Each to there own. But they could be there for life sadly. Try bio-oil first or go to a chemist and see what he suggests.
