Your Makeup Bag Is Lying: 9 Products You Need to Toss Now

Published: May 14, 2026 Last Updated 24 seconds ago by FPN

Your makeup bag has a secret. Tucked between that trusty red lipstick and the highlighter you bought on a whim, some products have quietly turned against you. They look the same. They smell mostly the same. But somewhere along the way, they stopped being beauty tools and started becoming breeding grounds for bacteria.

Here is the truth that no one tells you: makeup does not last forever. Unlike fine wine, it does not get better with age. Every time you dip a brush into a cream blush or pump a wand into a tube of mascara, you are introducing bacteria, oil, and dead skin cells into the product.

Over time, those contaminants multiply. The preservatives that once kept them at bay lose their effectiveness. And what was once a harmless beauty product becomes a potential hazard for your skin and eyes.

According to cosmetic chemist Ron Robinson, once makeup passes its expiration date, “active ingredients and preservatives start to become less effective.” That means your products won’t work as well, and you are putting yourself at risk for irritation or infection. Dermatologist Shilpi Khetarpal, MD, of the Cleveland Clinic warns that expired makeup can cause unexpected breakouts, infections, and allergic reactions.

The good news is that cleaning out your makeup bag is simple once you know what to look for. Here are the ten products you need to toss right now, along with exactly how to tell when they have turned against you.

If you only remember one number from this article, make it this one: mascara expires after three months. Some experts say you can push it to six, but everyone agrees that mascara is the most dangerous product in your bag.

Here is why. The wand goes from the tube to your lashes and back again, every single day. It picks up bacteria from your eyes and deposits them directly into the liquid formula, where they thrive.

Cosmetic chemist Jim Hammer explains that mascara has “one of the shortest PAOs due to its high potential to get directly into the eyes and cause serious infection”. Lingering bacteria can cause redness, itchiness, conjunctivitis, and styes.

Mascara that has expired will often develop a distinct gasoline-like smell, according to makeup artist Pati Dubroff. It may also become dry, flaky, or clumpy. If you experience any eye irritation, toss your mascara immediately and replace it with a fresh tube.

Liquid foundation and concealer are water-based, and bacteria love water. Once opened, these products typically last six to twelve months. Powder versions last up to 2 years because they contain less moisture.

How to tell they have gone bad: Look for separation. “Separation can be seen as an oil layer forming on top, color not distributed correctly throughout the product, or a water layer forming on the bottom,” says cosmetic chemist Krupa Koestline. Separation reduces the effectiveness of the preservative system, thereby increasing the product’s susceptibility to contamination.

Other signs include changes in color (such as foundation turning orange, a classic sign of oxidation), an off smell, or changes in texture. If your concealer is meant to cover blemishes but is now making them worse, throw it away.

Cream products have a shorter shelf life than their powder counterparts because their moist environment is ideal for bacterial growth. Cream blush should be replaced after one year, while powder blush can last up to two years. Cream eyeshadow is even more delicate, with some experts recommending replacement after just 6 months.

How to tell they have gone bad: Texture changes are the biggest red flag. If a cream formula has become so hard that it will not budge from the compact, it is time to buy a new one.

You may also notice a white, chalky layer forming on top of cream products, which is a sign of bacterial growth. For powder blushes, a dull gray film on the surface indicates that oils from your face have transferred onto the product, causing it to degrade.

Like mascara, liquid eyeliner comes into close contact with your eyes and should be replaced frequently.

Most experts recommend replacing liquid eyeliner every three months, though some say you can push it to six. Pencil eyeliners last longer, up to one to two years, because you can sharpen away the contaminated outer layer.

How to tell they have gone bad: Liquid eyeliner that has expired may become thick, clumpy, or difficult to apply. It may also develop an unpleasant smell.

For pencil liners, a white film on the tip that cannot be sharpened off is a clear sign that the product has expired. If you have had an eye infection, throw away all your eye makeup immediately to avoid reinfecting yourself.

Powder eyeshadow is one of the longer-lasting products in your bag, but it does eventually expire. Because eyeshadows are applied near a mucous membrane, there is a higher risk of transferring bacteria to the product and then back to the eyes. Most experts recommend replacing powder eyeshadow every one to two years.

How to tell it has gone bad: Powders can become dried out and cracked over time. Exposure to heat and moisture can cause microbes to grow, and exposure to light can cause colors to change.

If your once-vibrant purple shadow now looks faded and gray, it is time to let it go. Brightly hued cosmetics change color faster than neutrals, so they may need to be replaced sooner.

Lip products have a longer shelf life than many other cosmetics because they typically do not contain water, which makes it harder for bacteria to grow.

However, because they are repeatedly exposed to the mouth area, experts recommend replacing lipstick and lip gloss after one year.

How to tell they have gone bad: Lipsticks and glosses contain oily ingredients that start to smell like stale cooking oil over time. A lipstick that has gone bad will feel hard and will not spread pigment smoothly on your lips.

An expired lip gloss will feel streaky and globby. If you have recently been sick, throw away any lip products you used during that time to avoid reinfection.

Powder products, both pressed and loose, are the longest-lasting items in your makeup bag. They can typically be kept for up to two years. However, some powders contain small amounts of water from botanical extracts, so there is still a risk of bacterial growth if they are stored improperly.

How to tell it has gone bad: If your powder has developed a hard, crusty layer on top that resists your brush, it has likely absorbed oils from your face and should be replaced.

Changes in color or smell are also signs that it is time to toss it. Storing powder products in a cool, dry place away from your bathroom can help them last longer, as heat and humidity accelerate breakdown.

Makeup that contains sunscreen has a shorter shelf life than regular makeup. Once opened, the SPF ingredients start to degrade, and after six months, they are significantly less effective at protecting your skin from UV damage.

If sun protection is important to you, it is better to use a separate sunscreen under your makeup rather than relying on SPF-infused cosmetics.

How to tell it has gone bad: In addition to the usual signs of expiration like changes in smell, texture, or color, you should assume that any SPF makeup older than six months is no longer providing adequate sun protection, even if it looks fine.

Your tools need attention too. Makeup brushes can last for years if they are cleaned properly, but when the bristles start to fray or fall out, it is time for a new set.

Disposable makeup sponges should be replaced after two uses. Even high-quality sponges like the Beauty blender should be replaced every three to six months because they are “little bacteria pits” if left sitting around.

How to tell they need replacing: If your brush sheds bristles every time you use it, if the ferrule (the metal part) becomes loose, or if the bristles feel rough and scratchy instead of soft, it is time for a new brush.

For sponges, any visible deterioration, persistent staining, or unpleasant odor means it is time to toss it.

The Universal Signs of Expired Makeup

Beyond specific timelines, there are universal signs that any product has gone bad. First, trust your nose. If a product smells like chemicals, sour, rancid, or just different from how it smelled when you bought it, throw it away.

Second, check the texture. Clumping powders, separating liquids, and gritty creams are all signs that a product has degraded. Third, look at the color. Makeup oxidizes over time, meaning oxygen causes it to change color.

If your foundation looks orange or your blush looks faded, it has expired. Finally, pay attention to how your skin reacts. If you are having unexpected breakouts, irritation, or allergic reactions, your makeup may be the culprit.

How to Prevent This Problem

Once you have purged your expired products, you can take steps to make your remaining makeup last longer. Always wash your hands before applying makeup.

Clean your brushes and sponges regularly with gentle shampoo or brush cleanser. Do not store makeup in your bathroom, where heat and humidity accelerate bacterial growth. A cool, dry place like your bedroom is much better. And always close jars and caps immediately after use to limit exposure to air and contaminants.

Your makeup bag should make you feel beautiful, not give you a stye. If you cannot remember the last time you bought a new mascara, it is definitely time for a new mascara. Set a reminder on your phone to do a makeup clean out every six months.

When in doubt, throw it out. Your skin and your eyes will thank you. And the best part? Throwing out old makeup makes room for new makeup. That is a silver lining we can all get behind.
