Eh..i am not sure of any overnight treatments...skin doesn't really work like that, but i know toothpaste dries them out which controls the oil the produce for a certain amount of time and diminishes them accordingly, but it could leave after blemishes.

One thing i would really suggest though is the oil cleansing method which is what I use. It works like a charm for me, but the trick is not using too much oil and wiping it off completely afterwards. Essentially what itdoes is the sticky viscosity of the oil catches whatever dirt particles are in the pores when you steam your face and the pores open up, then you wipe it all off with a clean towel, rincing it off after every wipe and go about your day. My only concern with this method would be that idk if there will be a purging stage for you, because there was not any for me, but I have read that others have had it. Google it a bit and see of it is right for you. Typing in oil cleansing method and forums will give you more personal experiences from people.

I've read so many overnight treatments for pimple on the BG page....

here are a few ideas..
