ok many things have helped my lips-calcium, fatty acids, potassium and alkalizing, what seems to be working the best thus far is iron. I was feeling tired and went to the dr. my hemoglobin was normal but I asked to get my ferritin tested (ferritin tests storage iron). Turns out my storage iron was very low, four weeks after iron supplementation (Floradix liquid) my lips are not peeling anymore. Something that iron has done that the other supplements didnt do was make my skin and lips stronger and more plump. Please get your ferritin tested, its a cheap test to get.
I have seen Peeling lips listed as a symptom of iron deficiency on the web.
