Anyone who’s dealt with this year’s particularly brutal cold and flu season likely wants nothing more to do with the stuff. So naturally, there’s a frantic disinfecting of surfaces and washing of bed sheets that follows any bout of illness—big or small. One place that you might not think to scrub down? Your makeup bag.
But it turns out, you should. Those red-tinted balms and waterproof mascaras that made you feel half-human could now be harboring sickly germs that could bring on round number two of illness.
“Cold and flu germs can live on products and surfaces for up to several hours, but other factors such as room temperature, amount of germs, and humidity play a role in the survival,” advises Morgan Statt, health and safety investigator for ConsumerSafety.org. In her opinion, you’re better off safe than sorry, though the question of whether or not to ditch a product depends on where and when it made contact with your skin.
Additionally, Statt and cosmetic chemist Ginger King add that water-based products contain preservatives that are meant to temper mold and bacteria growth. Statt cautions, however, that these protective ingredients only last a year or two, so they’ll be rendered useless in products that have been sitting in your makeup bag for the better part of a decade.
