Hello i am new to this forum. Ive had crusty lips for almost 20 years. I tried lots of things on them like Vaseline coconut oil castor oil emu oil chapstick etc. Nothing worked they always built up a crust after a couple days and would stay on indefinitly till i bite it off. My ec was caused by ocd lip licking. It would sap the water out of my lips. I beat my ocd lip licking habit and now just sip water throughout the day and when i wake up from mouth breathing all night i nibble a little bit but that is the only time i nibble. The trick for me was keeping them hydrated with water so they didnt dry out.
