Just thought I'd fill you in on my findings using the soap method.
Basicaly I'm not cured BUT my lips are in the best shape they have ever been. I'm on a 3 day peeling cycle and all of those 3 days my lips look great. Also no little white line appears. I apply the soap 2 times a day (when I wake up and when I go to sleep). Also when I do exfoliate it is much easier to do so.
