for how long you have EC.
it is burden on chest or mind.

I think I found the solution but I don't want to say it's the "cure" yet since I'm still in the process of recovering. But what I've been doing is dipping my mouth in Dead Sea Salt mixed with water to kill all the bacterial in my lips as well as to stop inflammation. To cure a wound you must make sure it's not infected. I've been doing it for 2 weeks and my lips went from extremely raw where it would stick to each other at night to slowly gaining more layers to my lips and they don't stick to each other at night. They also don't look red and inflamed. Maybe if your desperate for a solution just try this, I a.tually believe this is he cure. Get a cup of water and mixed it with 1 tea spoon of Dead Sea Salt and soak your lips in it for ~10-15 mins. After it's done get a cup of clean drinking water to clean the salt out. Do this Once or more a day. Your first time will peel all the Dead skin out and your lips will be at its rawest but you need to create a clean area to heal. Keep doing this and you will recover I believe so.

maybe ask your dermatologist about trying tacrolimus ointment

Sorry but if you really do have exfoliative cheilitis i dont know if thats a mental problem. I see people treat their lips like shit - licking all day, injections, mouth breathing - and they dont have exfoliative cheilitis.

blaming exfoliative cheilitis on "mental problems" is an easy & convenient answer for a very complicated, rare, mysterious condition but if you think that your cheilitis is due to a mental problem you could try seeing a psychologist for ways to not manipulate your lips if you do that or you can try medications which could relax you or you could try wearing bandaids, tape,
gloves on your hands if your hands are the problem.

i think everyone with exfoliative cheilitis is hopeless bud, im sorry to say. its a horrible situation.

I have been "maintaining" my lips for years now so it has not kept me from doing things anymore. When I get nervous or anxious my body will respond by sweating and/or making my mouth dry. which in turn make me focus on my lips.Especially if I left my lips alone for 3-4 days. I dont think the cause is mental. An attributing factor might be. I think it's a difficult area to heal.
I wondered many times how I would be able to keep/get a girlfriend with this condition. As with any condition, your partner should be compassionate or accepting. I have had girlfriends with this & I am now married.
