Water is water. If you keep rubbing a wound and washing water over it, it will not heal. I developed a strange bleeding wound on my right little finger and for some reason it took months to heal. I could see the superficial layer of skin was so damaged the finger print dissapeared to the point where I thought it was permenant skin damage. I think the damage originally must have been caused from allowing sanitary silicone to sit on the skin for to long. Any tiny bit of rubbing or friction against the little finger would cause the skin to peel and bleed. Eventually it did heal over. I believe this is what the skin in the mouth and lips requires to heal itself. There is no magic method or cure. Daniel Miller took over 6 months of leaving them alone. He's done it and so can we.
