I'm currently doing 2 hour sessions every week. Hey, if I have to spend 3-4 days growing the crop, I want to get as much harvesting done as I can stand. (And I really want the beard gone. Dysphoria trigger!) The treatment mode is thermolysis. I've had almost no scabbing.
My electrologist does something with a round electrode rubbed over the skin at the end of the treatment, and applying some sort of lotion that seems to help. On the way home, I'm icing down the skin repeatedly during the hour drive, using a balloon filled with water, tied off, and frozen. (The electrologist provided these, and I have a freezer bag with more to last me the drive home.)
I generally shave within 15 minutes of getting home, less if the cats don't need attention. I leave the area clean, and ice repeatedly till bedtime. I do use Cetaphil lotion on the area the next day, and always use sunblock.
