My lips are almost cured by using epaderm. I have to use it twice or thrice a day but my lips doesn't crust. There is a little buildup which i rub off after brushing my teeth in the morning. I don't know if there is a cure but epaderm helps me manage my ec and go about my day without thinking about my lips. 5 years I struggled and i have been using epaderm for 6 months for managing my lips. I have tried a lot of things which you can red in my previous posts but nothing helped.

Try it for a month or two and see if it helps. Since I peel off the buildup everyday, there is no crusting but after I started using epaderm, the buildup is very minimal and some days there is no buildup at all. It might not be a cure but it is close to it. My lips look normal. It is similar to daniel millers cure. He also has to apply lip balm to maintain his lips.
