The fact that your lips haven't been building up is a HUGE breakthrough. I can't watch the video right now because I'm at an overnight shift at the hospital. But your clearly seeing fantastic results with your current method so definately keep at it. As far as lip lines etc go those should come in time.
And seriously f*** the people who are hating on you. Your one of the leaders, if not THE leader of the movement towards a collaborative community that will one day beat this god-awful curse. If it weren't for people like you, people would still be getting steroid creams, peeling the shit outta their lips and then complaining how steroids make it worse. Keep at it bro your gettin there!
