clofazimine is the drug that cured a previous man with cheilitis. you may want to reconsider the vermillionectomy since I don't see how it could make your condition worse. you could try a laser vermillionectomy to just a small area and see how it responds. I have had an inflamed salivary gland and it secretes a thick clear substance that turns the mucosa white when wet then the skin drys and turns yellow. anyways goodluck.
