I have systemic candida and have had it for around 20 or more years. My lips have been chronically and painfully chapped for eons. Nothing I put on them helps. They are so dry, there are scabs on the right now, from picking the dried skin off of them (if I don't pick the dried skin off, it gets much worse). I 've always wondered if mine was caused by candida or one of the other autoimmune issues I have.
