Still doing some research. Found many articles from my university library. Here's one that I came across. Still haven't read through it, but I got so excited I wanted to share with you right away. Thought you all could read with me and see what you think. Maybe you could research "tacrolimus." Here's the citation:
"Exfoliative cheilitis successfully treated with topical tacrolimus"
Authors: M. Connolly, C. Kennedy
Published in: British Journal of Dermatology
Found other academic paper & journals about EC, but looks like causes & cures are so elusive. Some patients managed by taking antidepressants. There seems to be some psychiatric factors involved--obsessiveness mainly. For now, it looks like treatment for EC seems to just be "management" of it.
