Do you think there is that much of a difference between letting the crusts come off while using water in the shower and using water while brushing teeth? It don't put my face into the stream of the shower head. It's pretty gentle. No force.
Here are some pictures of before and after shower and after the "final peeling" :-P It might not be 90% as I've stated before, but most of it anyway. The stuff on the bottom of the bottom lip is basically the skin from the peeled part, but the skin is hanging down.
