Whatever is causing this people. The lips will never heal unless they can obtain the moisture from within our body. It must be something to do with sebaceous glands which allow this to happen. Fordyce's Spots are extremely common on here. These are misplaced / blocked sebaceous glands. Find something to unblock the pores and we'll have found something to help sort this out.
I've read some absolutely hilarious things on here after returning to read a week or two ago. Someone was pecked on the head by a bird in their childhood and this caused EC!?!
Some people on here have let this condition drive them insane.
Find some topical creams which help, peel when required after the lips have been soaked well and get out and live life. I wasted 18 months of my life worrying about this condition before I realised people hardly notice it if I manage it correctly.
