I have tried the shea butter, seven balm, lysine lip ointment, and the emu oil. The shea butter, the seven balm, and the emu oil all worked magnificently even when outdoors. The emu oil works not only rats but humans lol. Just remember to get the pure emu oil by itself from australia. Also I used to get cold sores, and the lysine lip ointment made them disapear really fast. By the way, I have noticed peeling lips, can cause other problems in the mouth. For instance, dry mouth, and cold sores. I think those symptoms may reflect on the cause and what you need to do to reverse those effects. Healing starts at the vermilion border!
