Hi, I had also been suffered from exfoliative cheilitis, now its been almost 15 years passed that i could not get rid of from this disease. I have spent a lot of money for the cure but with no outcomes. I am also experiencing that when i uses Lip balm over my Lips then Lips are getting blackish colour and a thin film of black material is accomulated over there as well as my Lips are growing thicker and deshaping my face badly. I am really very upset and disappointed to hear that there is no proper cure for this disease. Please help me out from this trouble by giving me useful tips . I will be very thankful to you. Please note that i have no any fillings of any type in my mouth. Regards Yours Truly
