I accidently removed the crust on the left side of the lower lip last night. The skin underneath was red but not raw. Today I did more trimming. A couple of hours later I could do some more. I only trimmed the skin that had gone completely white and was hanging loose. For the moment the skin on my lower lip seem to be build up in thin layers if you compare them a couple of weeks ago. We'll see if they stay that way. Be well you all!
