Chronic lip skin peeling in every 4 days

I have been suffering from a condition in which lip skin become hard and peel off in every 4 day interval . I have been suffering from this condition for around 4 years . Doctor call it as Exfoliative cheilitis. I feel like i have exhausted with treatment. Doctors in past suggested lots of topical steroid & non steroid immune suppression creams . But none of them work . medicines: Cinort, Himalaya lip balm, Tacroz 0.03%, Tacroz 0.1 %, Vasaline, T bact, Desowen, Kenacort 0.1%, Vaseline ,Elovera, Emolene , Candid -b, Psorolin, Betagel, Pacroma, Nfm e lip balm. When lip skin peel off which exposes raw skin underneath it. Now i feel like my body tries to build back protective skin layer again to protect that wound . But that protective layer becomes hard & it breaks (or peels off) within 3-4 days  i feel like this disturbs the healing . is there any cream that can act just like a artificial skin so that it can prevent from excess skin production on lips and heal lips . please help me
