Have you gone to an allergist? I have been dealing with peeling chapped lips for years. Just a few weeks ago, I finally decided to go to an allergist. Turns out I'm suffering from an oral allergy syndrome, where most of the vegetables and fruit I was eating was causing allergic reactions that manifested in my lips. It was a rather difficult transition at first because I found out I was allergic to simple things like potatoes and corn and on top of that I had the cross reactions to many vegetables and fruits. I was a vegetarian, so obviously my diet had to change dramatically. I'm not allergic to meat and dairy. Urgh. But making the change has helped my lips dramatically. They still peel sometimes when I'm not careful about what I eat, but they are doing so much better. Try going to an allergist at least to see if you are allergic to some common, mundane things.
