We've kind of talked about these a little on the bazillion Sephora threads.
I usually prefer the Clean & Clear ones as they work good, don't mess up my makeup and they're inexpensive (around $3.50 or so for 50 sheets).
Well, I tried a different kind yesterday that I liked, so I figured I'd tell ya'll about them. I got them at Sally Beauty and they're by Palladio. They're rice paper sheets and were $2.99 for 40 sheets.
I have the oily T-zone from hell and it's even worse in the summer, so I need something that will help soak up that nasty excess oil (an extra dusting of Mineral Veil just doesn't cut it sometimes). These seemed to do the job pretty well. You can blot with either side of the paper (the matte side has ride powder in it). And it doesn't mess up your makeup, which is a huge plus for me.
Just wanted to throw out another option for those of you who might be interested and would like another inexpensive option.
