Help with scar?

I have a 4 inch scar running along my jaw bone line. Until reading your question I had not thought about it months. People i meet don't seem to notice it (until weeks later maybe) despite it being blindingly obvious. I used to be aware of it and turn it away from people, but as I found it didn't repulse them, I began to forget it was there. My honest advice is to live with it... it's far from important in the grand scale of things. Not meant in a nasty way, good luck in whatever you choose.
