I have some scars from.... Regretful actions in my past. How would I go about making my skin pure again?
Depends on how long you've had the scars for. Since you say they're from your past, I'm not sure what you can do to get rid of them. For new scars that just formed, Vitamin E oil and/or Aloe Vera really help. You can try using those on old scars, too. I've heard wonder stories, especially for Aloe Vera.
It depends on the thickness and depth of the cut. If it's very thin and deep then you will find it difficult to get rid of. If it's thicker and shallow then it will fade after a few months. Either way, bio oil will help as people above have said and it will be less noticeable after time. If you're rich and/or bothered enough there's always plastic surgery but it's not really recommendable for such a small thing unless it's really psychologically bothering you, and it has the potential to leave scars of its own of course. Just learn to live with your past and feel comfortable in your body (*hug*)
I had 6 stitches above my eye from bashing my head of a rock, hiking, and I found Emu oil helped. Yes, Emu oil, from the bird. Not Emo oil. That will make your hair turn black, and other things!
