It's probably time to replace your toothbrush (and mascara and lip gloss and razor blades).

Raise your hand if you've had a tube of (definitely expired) mascara knocking around in your makeup bag for over a year now. Or how about a lipstick you've been swiping on for a decade? Unless you routinely set aside time to clean out your cosmetics stash, it's all too easy to keep makeup, toiletries, grooming tools, and medications long after their expiration dates. We're all guilty of it—but it's time to make a change.

Not only are all of those past-their-prime grooming products taking up valuable space in your medicine cabinet or makeup bag; using old tools and makeup could actually result in dangerous skin and eye irritations. In fact, a recent UK study found that 90 percent of beauty products—particularly sponge makeup blenders—are riddled with potentially "deadly superbugs," including E.coli and Staphylococci. Exposure to these unwelcome bacteria (which thrive in damp environments—aka makeup sponges and lipstick tubes) can lead to things like skin infection and blood poisoning, at worst. And when you think about what these things are touching—going from your fingers, to your face/mouth/eyes/pimples, and back to the product again—it's easy to see why it's dangerous to keep them for so long.

All this is to say, you need to know exactly what to throw out, and when. To be fair, it's hard to tell what a product's expiration date is, because it's not quite as clear as it is for food products, which are typically stamped with a "sell by" or "best by" date. To make matters more confusing, some products simply don't suggest any expiration date. So to figure out what can stay and what needs go, here's a comprehensive breakdown of every toiletry and makeup expiration date. You'll never use germ-ridden makeup sponges, brow wands, eye cream, or sunscreen ever again. (Promise?)
