Oil slicks.

A handy-dandy packet to keep in your purse! Just swipe over your face when you're feeling mid-day greasies. Soaks up excess oil and leaves you with a matte finish.

:: Clean and Clear Oil Absorbing Sheets ::

Good things:
Doesn't use powder, like some sheets, which feels cakey.
Doesn't take off makeup.
Even guys can use them, and are usually tickled at the sight of their own oil.
Doesn't strip or dry out skin.
Cheap! ($5 or less at Target, etc.)

Bad things:
Packaging could be better, but for the price you can't expect much.
