You see these last few posts are why I'm leaving, why put so much energy into doubting people?
I have literally watched my lips layers of skin rebuild from zero skin to now several layers. This is not a wound. I sometimes get a bleed in my lips and it will heal pretty much overnight. This is rebuilding several layers of skin and in my case it worked from the centre outward. So the centre of the top lip built itself up first and this is the thickest part of the lip so takes the longest and then I witnessed it slowly rebuilding outwards until not eventually it has reached the corner of my lips and it is all covered and rebuilt again. It's not just happened overnight and it would take along time of picking, Chapstick, smoking, drinking etc to get my lips back down to the state they were in before.
I've read loads of this forum now and it seems it goes in cycles. Someone will come up with a miracle theory such as lemons, diet, steam, cream blah blah and then for the next few months this will be spoken about with great authority that this is the cure. Then the person will mention that it doesn't really seem to have helped or has caused another side effect and it will be dismissed.
There is no cure you have to let the lips rebuild themselves and they do that from the inside out and until they are completely rebuilt they will continue to shed the outer layer because there are not enough inside layers for it to stay on.
