You know it really depends on the brand of the makeup. Not all mineral makeups are created equal. I have tried many brands. I would sleep in the bare minerals brand, as seen on tv. It is so light and so natural. But many of the newer store brands still seem to effect my skin like any other makeup. I'd just pay really close attention to the way the makeup actually settles durning the day. The bare minerals never changes on me no matter how long I have it on. If I apply it at 6am it is still as nice and light at 8pm, but others like the loreal become heavy and settle quite a bit on my face, so I wouldn't dream of sleeping in it.
