I'm curious about if it'll help. I might be able to convince my derm to also do it on me (or I'll find someone that is able to do it on the lips).
Maybe I'm not doing the leave them alone treatment correctly, or we have different conditions, but my crusts usually fall off completely (or I help them off once they are completely separated; sometimes just parts of my lower lip, and sometimes most of it when it's just mostly one crust that has build up). Your crusts seem to merge with the skin thats building up underneath? Doesn't it get thicker and thicker when they never fall off? Do you trim the edges?
