I have very thick skin, so I've been told exfoliation is necessary since the thick, sticky cells become plugged and then sprout a pimple, usually the deep cyst-like type. I started using a microdermabrasion device from neutrogena to get down to a "less sticky, clumpy" layer. It's only $30 and i use it sometimes twice a day...generally i use it until my skin becomes irritated and back off for 24 hours. I'd suggest you try the same with BP...let your skin tell you when it's had too much, then begin again when it recovers.
