have yourself check out by a dermatologist, cheilitis is a like a fungus but i dont know if ur constantly licking your lips ( the corners )or cosmetics can do something to it as well, sun etc...try vitamin e on them and see where it goes but if it continues have it checked out, you may need something stronger , i sometimes exfoliate my lips with something very soft to remove all the dead skin and i use baby oil then apply the E.see if it works for you.
