When to Toss Your Makeup: A Complete Expiration Guide
By Viktoria @vioda.makeup · · Updated April 11, 2026
That mascara you've had since last summer? It's time. Here's a no-nonsense guide to when every product in your bag should be replaced.
How long makeup really lasts, signs products have gone bad, and practical tips to extend the life of your collection without risking your skin.
Why Expiration Dates Matter More Than You Think
Makeup doesn't last forever. Every product has a PAO (period after opening) symbol on its packaging: that little jar icon with a number like 6M or 12M. That number tells you how many months the product is safe to use after you first open it. Most of us ignore it completely, and then wonder why our mascara is clumping or our foundation smells off.
Expired makeup isn't just less effective. It can harbor bacteria that cause breakouts, eye infections, and irritation. The preservatives that keep products safe break down over time, especially once air, moisture, and your fingers have been introduced. If you've ever gotten a stye or a mysterious rash, your old makeup could be the culprit.
Product-by-Product Shelf Life
Mascara has the shortest life: three to six months, no exceptions. It's a wet formula that you pump air into every time you use it, creating a breeding ground for bacteria near your eyes. Liquid and cream foundations last six to twelve months. Powder foundations, blushes, and eyeshadows can last up to two years because dry formulas are less hospitable to bacteria.
Lipstick lasts about twelve to eighteen months. Liquid lipsticks are closer to twelve months. Lip gloss is six to twelve months because the applicator touches your lips and goes back into the tube. Pencil liners (lip and eye) last about two years since you sharpen off the exposed surface. Cream and gel liners are more like six to nine months. Setting sprays and primers generally last twelve months.
Signs Your Makeup Has Gone Bad
Trust your senses. If a product smells different from when you bought it, especially if it smells sour, metallic, or like crayons, toss it. Changes in texture are another red flag: foundation that has separated and won't re-mix, lipstick that feels grainy, or mascara that has dried out and become flaky.
Visual changes matter too. If your cream blush has developed a hard film on the surface, if your powder has white spots, or if your liquid products have changed color, they're done. Some people try to revive dried-out products with setting spray or oil, and while this might temporarily restore the texture, it doesn't restore the preservatives. Once a product has turned, resurrecting it just means applying bacteria to your face with better slip.
How to Extend Product Life
Store makeup in a cool, dry place away from direct sunlight. Bathrooms are the worst spot because humidity and temperature swings accelerate breakdown. A bedroom drawer or a dedicated makeup organizer in a closet is ideal. Keep lids tightly closed and never leave products uncapped between uses.
Wash your brushes and sponges regularly. Dirty tools transfer bacteria back into your products, shortening their lifespan significantly. Use a spatula or clean finger to scoop cream products out of pots rather than dipping directly. If a product comes with a pump or an applicator that doesn't require direct contact, even better. And resist the urge to add water or any other liquid to a drying product. Once the formula is compromised, it's time to replace it.
Special Cases: Natural and Clean Beauty
Products marketed as natural, clean, or preservative-free often have shorter shelf lives than conventional makeup. Fewer preservatives means the formula is more vulnerable to microbial growth once opened. If you use clean beauty products, pay extra attention to the PAO date and consider writing the open date on the product with a marker.
Organic and plant-based ingredients can also oxidize faster, changing the color and performance of the product. This doesn't mean clean beauty is worse. It just means you need to be more disciplined about replacement timelines. If you don't use a product frequently enough to finish it within its PAO window, buy the smallest size available.
A Practical Replacement Schedule
Here's a simple system: every three months, check your mascara and replace it. Every six months, audit your liquid products like foundations, cream blushes, concealers, and liquid liners. Once a year, go through your full collection and toss anything that's been open for over twelve months, especially lip products and anything that touches your eyes.
Write the month you opened a product on a small piece of tape and stick it on the bottom. This takes two seconds and removes all guesswork. If you're the type to hoard makeup, be honest with yourself about what you actually use. A drawer full of expired products isn't a collection. It's a skin problem waiting to happen. Keep what you love and use, and let go of the rest.
