How Long Does Mascara Last

If you’re a makeup lover, you’re probably wondering, “How long does mascara last?” The answer varies, of course, depending on the makeup product. Many mascaras can last up to three years after they’ve been opened. That said, you might want to consider buying a new tube of mascara if your old one is showing its age.

Whenever I buy mascara, I always check how long does that mascara last. I want to keep using that mascara forever. But that is not possible. After some time passes, I have to throw it and buy a new one.

It is very difficult to decide whether to throw out mascara or not.

I am sure you are also wondering and facing the same issue. For me and for all my readers, I have done some research about how long does mascara last.

Here is my research.

How Long Does Mascara Last?

In most cases, mascara lasts for a year, depending on your use and how you use it.

After a year, I would suggest that you replace it even if it is not used. If you are using it rarely, it can last you over a year, but you have to store it properly.

Factors Affect a Mascara’s Longevity

The shelf life of mascara depends on its formula and brand. However, some brands can last up to eight months if they are stored properly. However, it’s best to replace it every few months or so to avoid damaging your eyes. Other factors affect the longevity of a mascara. Here is a list of the factors.


Mascara storage is very important. You have to keep it in a cool and dry place away from direct sunlight. Keep it as standing, or lying down in a bag. Also, it is very important to keep changing its position.


It is very important how you apply and use it. With a small thrust, the air is forced into the tube and it may affect its life span.

Mascara should be cleaned frequently. Make sure that your wand is clean and dry after each application. Keeping your wand clean can keep mascara from clumping.

Leaving the Tube Open

Do not leave the tube open. It is one of the common mistakes we all do. It will dry out your mascara.

Another factor that affects the shelf life of mascara is its brush. If the brush becomes wet or contaminated, bacteria can grow and spread. This can cause eye infections. Therefore, you should throw out any mascara that is more than three months old. If this is the case, you should immediately visit an eye care professional.

Does the Shelf Life of a Mascara Matter?

Yes, it matters a lot. But there is a difference between shelf life and expiry date.

Mascara is one of the most popular beauty products available in the market today. The shelf life of mascara depends on the brand, formula, and preservatives used in the manufacturing process. In general, mascaras should be used within a three to the four-month period after purchase. However, some products may expire earlier than this. In such cases, it is best to use them as soon as possible.

Shelf life is not important as compared to the expiry date. If you store your mascara right, you can use it beyond its shelf life mentioned by the manufacturer.

Keeping your mascara properly is crucial to its effectiveness. Makeup that has an expiration date of at least three months is best. Eyeliner and eyeshadows have different expiration dates and should never be used if they’ve gone past that point. You can also check the ingredients label before buying.

As a rule of thumb, you should replace your mascara after three to six months, depending on the brand and formula. In addition to its shelf life, you should also consider its smell and performance. If it begins to smell musty or sour, it’s time to replace it. Also, it’s a good idea to stop pumping if the wand is getting dried out. This might indicate that bacteria have begun to grow.

Yes, the recommended time is 3 months after opening the mascara due to bacteria reaction.

Does the Expiration Date of Mascara Matter?

Yes, it is very important. You should not use the mascara after the date mentioned on the packet or tube.

I would not suggest using it after the expiration date. So always check the expiry date.

What happens if I use Bad Mascara?

Old mascara can make your eyelashes dry and brittle. It can also harbor bacteria. In addition, it can smell bad and look gross. It’s best to replace it every three to six months to protect your eyes.

You should not use bad mascara. Using old mascara can lead to bacterial infections, eye irritation, and clumping.

How to Protect Mascara?

To prolong the life of your mascara, store it in a cool, dry place. Keep it away from direct sunlight and in a dark place. This will extend its shelf life by about three to four months. After that, the product will start to dry up, become powdery, and become thicker. It’s also important to avoid using expired mascara, as it could cause infections, irritation, and red eyes.

If you notice that your mascara has reached its expiration date, you might have to buy another tube to replace it.

What are the Signs of Mascara Having Gone Bad?

One of the signs that your mascara has gone bad is that it has clumped. Mascara should be replaced when it has clumped and becomes too dry. You can purchase a new one at your local drugstore. Look for a symbol on the container of the product that indicates how long the product is good for. Most products will have this symbol.

An expired tube of mascara can cause your eyes to become irritated or infected. Fortunately, it is easy to tell when mascara has gone bad. The expiration date of the container is usually three months. If you find this on your mascara, it’s time to throw it away.

One of the best signs of expired mascara is a chemical odor. If the product starts to smell like alcohol or something bad, throw it out. Another sign is a film on the top. Expired makeup may even have bacterial growth.

Mascara has a short shelf life and should be discarded after two to three months of usage. It should also be discarded if it has an eye infection. Bacteria will live in the mascara and can cause infections. Moreover, if the mascara has clumped or is dry, it’s more likely to cause eye infections.

Is Dried Out Mascara Bad?

No, but Dried mascara is difficult to use.

How Can I Fix Dried Out Mascara?

Fortunately, you can easily fix the dried-out mascara with some warm water.

Take your dry mascara and dip it in warm water.

How Can I Make my Mascara Last Longer?

According to my experience and my research, there is no fixed solution or working guide to make your Mascara last longer.

But proper storage and hygiene can make it last longer.

Mascara is a staple in any makeup bag, and it can instantly transform your eyes. The right formula can add dramatic intensity to your look, or soften it for a natural accent. However, finding the perfect formula is not always easy. You must know how to properly care for your mascara to extend its shelf life and keep it from drying out.

First, be careful not to share makeup. Using another person’s makeup that isn’t your own can spread bacteria. It’s not only dangerous to share makeup, but it can also make your eyes irritated. If your eyes are irritated or sore, never use mascara on them. Bacteria can accumulate in the brush and cause itching and swelling.

Another way to extend the life of your mascara is by mixing it with saline solution or contact solution. Both these liquids have a viscous consistency and can help make your mascara more pliable. Using this method will allow you to apply it more easily. Just make sure to measure the amount you add, as too much contact lens solution can make your mascara runny.

Another way to make your mascara last longer is to apply it gently. Before applying mascara, roll it between your palms to warm the product a bit. This will allow you to apply it more evenly.

Also, avoid pumping the wand back and forth in the tube. Pumping it in and out will trap air and dry out the solution faster. Finally, after applying mascara, be sure to close the tube tightly. After using it, place it in a cool, dark place, and do not forget to keep it out of the light.
