3. Powder puffs / Compact applicators.
How often: Varies. Every week in the summer (or during periods of heavy use), and every other week in the winter (or when you’re not using it as much).
Method: Many people tell you to put puffs in a lingerie bag and toss it in the laundry; don’t do this. Instead, wash it the same way you would a sponge: with baby shampoo or makeup cleanser, lather (be gentle so that you don’t damage the fluffy hairs), rinse well. Allow to dry thoroughly on a clean towel—you don’t want any dampness coming into contact with your powder products!
Extra credit: If your puff has lost some fluff post-washing, a blowdryer on a low, warm (not hot) setting will help separate the fibers and poof it up again.
