Light scars go away in about a week or two. I know when my cutting was pretty light, I used things like a needle, and it is more like a scrape. So yes, just wait out the rest of the time and they will be gone forever!
If you have any bad, dark, or permanet scars there are things at stores that minimize scarring, make it lighter and less noticeable.
I DO NOT GO ON HERE ANYMORE. I HAVE LEFT THIS PLACE FOR GOOD AND DON'T INTEND ON COMING BACK. PLEASE DON'T FRIEND REQUEST ME, PRIVATE MESSAGE ME, OR ANYTHING BECAUSE I WILL NEVER SEE IT AND YOU'LL NEVER GET A RESPONSE. THANK YOU.
