For almost two year my bottom lip peels on a daily basis up to the right side where it forms a nasty sore. I have asked several doctors about this and have been given every cream from antibiotic, steroid, fungal, lip balms, Vaseline, vitamin E to you name it. Nothing works. I've mentioned it to my dentist and all he says is keep it moist. Strange how it doesn't effect my top lip at all. Any ideas out there?
