I'm using livia one. The propylene glycol diet didn't seem to work, my peeling lessened but still was there. I also have eczema which might be a cause of my own exfoliative cheilitis. I think they're somehow correlated. I'm now going on an Elimination Diet because I stopped seeing anymore progress with the previous treatment. I clip my lips daily, is that bad? I just dont like seeing my lips all crusty and clip off anything thats's hanging off.
