I have/had very similar problems to you. My skin doesn't like topicals anymore. It responded very, very well to BP initially and I was clear for a few months. After that I started getting flesh coloured bumps all over my cheeks that would not go away no matter what topicals I used. I used everything, prescription and non prescription. Even peels didn't help all that much. It seemed as though every now and again something would get rid of a bump or two very temporarily, but it would be back by the next day. These bumps were soft and weren't really full of anything. I also started getting the occasional painful red pimple that would inflame a good inch of my skin around it.
I've been on accutane for two weeks now. It's my last resort, so fingers crossed. Some of the smaller surface fleshy bumps seem to have been reduced. I don't think it's sebaceous hyperplasia - the derm at the hospital said it didn't look that way and I'm kind of young anyway -- 22. Maybe you could look into getting the same thing done?
