I have a couple 2-year-old scars which were the price of my learning-curve; a hairline scar on the right side, and a slight depression on the left where I once took a chunk out. Both have faded to the point where you need to be in the right light & at the right angle to see them, but both are still there. I used to put vitamin E oil on them, and now I use shave oil. Will they ever disappear completely? Is there anything I can do to fade them even more?
