Incomprehensible skin

God, my skin makes no sense to me. It seems to have become rather clear lately, despite the fact that I haven't been diligent with my acne wash recently. It could be that stuff just isn't good for me, but it seems like my skin gets better or worse randomly, regardless of the treatment or lack thereof it is recieving. I kind of want to just go to a dermetologist and say "What does my skin need to get clear?" and then actually know what the problem is the and the right way to deal with it. The trouble is that the insurance I'm on is kind of in flux lately, and I don't really have the extra cash to cover a visit on my own. Still, it might be worth looking into to see if I can actually do it.
