Eyeliner: Just like other eye products, you want to be extra careful with eyeliner. And make sure to sharpen your eyeliner (if it’s a pencil) before each use, says Cromwell. This will help to literally scrape off some of the germs.

Mascara: Want to avoid an eye infection? Replace your mascara often, since it’s a “breeding ground for bacteria,” says Cromwell. Another reason to toss your mascara every couple of months? It will start to dry up anyway, and spider leg lashes are not a good look.
