I self harmed pretty severely some years ago, and still have scars from it. The scars are all very old, the newest ones well over a year. They have turned the colour of my skin but are "protruding" in a way, it's very obvious what it is. I won't be able to serve in the military with these scars.
You can use bio oil or cocoa butter. I used to self harm and used bio oil on my arm too it works quite well.
I hope you have permanently stopped that harmful habit and possibly looked into the reasons you did that. If you are not completely cured of that aberrant behavior, you will not have a successful military career--to put it mildly. As for the scars, there is a new product on the market called Bio Oil available at most drug stores. You might want to try that.
well its going to take a while for them to go away. But keep adding healing ointment to them. Don't scratch them or pick at them bc it makes it worse. if you have any hydrogen peroxide that may help too.
