I have some self harm scars that are about 5 years old. They're paper white and slightly risen. In some lights they're barely visible, but in bright or natural lighting you can see them very clearly because they're risen, so makeup doesn't help.
I really need to fade them because I'm seriously considering working as a flight attendant in the future and these scars are bang in the middle of arm so they would not be hidden by the uniform.
Is it even possible to fade such old scars? They are completely healed and purely scar tissue. Obviously laser or anything like that is out of the question because I'm only 17, I need something cheap.
