How can I avoid germs in my makeup bags?

Anytime you use makeup, be it mascara, lipstick, or a compact, the germs on your hands can contaminate it. Make it a practice to periodically wash the outside of cosmetics cases and makeup bags. And throw out makeup that is old, especially anything that is applied to the eyes, which is sure to be a bacteria bonanza. Definitely resist using testers in the store or sharing makeup with friends.
