What does cured mean then? I dont need to put anything on my lips. All i need to do is drink a few glasses of water a day, and take a shower. Im just not being careful not to get them wet like i did for so many years. Im also not licking or biting. My lips had lost all moisture from lip licking and never getting them wet. The only cure was restoring the moisture content does this make sense or no. Moisture=water , constant moisture method=lots of water. Petroleum has no water its a oil get it?
