Touching your face with your hands can be a huge culprit too. Just think of all the things your hands come in contact with! By touching your face needlessly, you are inviting pore clogging bacteria to wreak havoc on your skin.
So make sure to wipe down your cell phone, (I like to use those handy little wipes made to clean computer monitors), change your pillow case often, (if you have a bad case of acne, use ea. side of your pillow once and then change), make sure to avoid touching your face (this includes picking/popping!), and wash your make up brushes often (click here for a how-to).
