There Might Be Infectious Bacteria Lurking In Your Makeup Bag, According to a New Study You already know that your makeup products and tools naturally harbor germs. A study proves that using certain products isn’t just kind of gross—it can actually be a serious health hazard. More than 9 in 10 in-use beauty products play host to "deadly superbugs," including E.coli and Staphylococci.

Make a habit of ditching makeup, creams, brushes, and blenders before they've passed their prime.
