Wash your make-up brushes once every 2 or 3 weeks to make them last longer and eliminate any icky, germy residue caused by cosmetics residue. Use a little bit of shampoo or brush cleaner (bareMinerals has a good one) under warm, running water and very important: lay flat to dry (on a double layer of paper towel) while giving them back their shape.
