sooo... After dinner(eating carefully) I had to brush my teeth, which I thought I did pretty good too. I noticed my top lipped had cracked more and turned more white. I decided to exfoliate the dead skin with the lemon juice. Just the top, the bottom remains the same for now. For anyone thinking of trying this, i hope you got a high threshold of pain. I do. It did bleed, it did burn. Like little needles going into your lip. It left the skin very raw. I got most the skin back off my top lip. Is this really going to heal it?
