Find Out if Your Makeup or Skincare is Still Safe to Use

No more guessing, sniff-testing, or risky swatches. Glou's Beauty Product Toss or Keep Checker and Product Freshness Calculator help you check how long they last after opening, and whether they're still good—all in seconds.

We've all done it—reached for that serum or lipstick that's been sitting in a drawer for... who knows how long. But when it comes to beauty, freshness matters. Expired formulas lose potency and can grown bacteria that irritate your skin or eyes.

That's where our Expiration Calculator and freshness Shelf-Smart Checker come in. Whether you're decluttering, rehoming, or just making sure your stash is safe, Glou helps you make smarter, cleaner, and more conscious beauty choices.
