New user, what method is effective?

Hey everyone
Long time lurker here, my lips have looked like this since November 2015, i have always been a chronic lip bitter so i am guessing that is the reason i have this. My question would be is there any methods that have been proven effective? I have tried probiotics, lip balms, hydrocortisone, leaving them alone and i always end up peeling them because they turn yellow and start to be bothersome. Is there any hope for this?
