Why It’s Awesome: Nothing is worse for your skin health than a dirty make-up sponge. These sponges from CoverGirl are great because they are so inexpensive, you won’t feel bad about tossing one. Bacteria can build up on your sponge instantly, which can lead to adult acne and other skin issues. So, keep a fresh one around and change yours regularly.
