I have a question about medical tattooing. 10 years ago I had some mental issues, this sadly resulted in self harm. While I asked Allah swt to forgive me, I am still hunted by my self harm scarring. I know that Allah swt is the Most Merciful and that He will forgive someone if they ask for forgiveness, sadly I cannot say the same about people. I feel that my scars close a lot of doors for me in life so i have looked into how I can make my scars less obvious. I also considered surgery, but that surgery costs a lot of money and it would need a skin transplantation from my leg (which would result in more scarring). I found out about medical tattooing, this is a procedure that fills in your scars with a similar skin tone as your own to make them less visible. My question is, is it permissible for me to get one for my self harm scars to make them less obvious?
