How Long Does a Tube of Mascara Last Unopened?

Mascara is an important part of a makeup bag. But it’s also a product that has an expiration date, much like any other beauty item. Expired mascara can cause eye infections and even grow a stye along your lashes, which is very unpleasant. So, throwing your mascara out when it reaches its end of life is best.

The question that many people ask is How Long Does a Tube of Mascara Last Unopened. Several different factors go into the answer to this question. Generally speaking, unopened mascara can last between two and three years. This depends on how well you store it and the ingredients in the product.

It is also important to remember that not all products will last as long as others, which is true of makeup. Expired mascara is unsafe to use and can cause eye infections. This is why throwing away any mascara that has been open longer than three months is always a good idea.

Things to keep in mind

If you want to know how long your mascara will last, it’s a good idea to check its expiration date on the package. This will help you determine when to throw it out and replace it with a new one.

Using an expired mascara can lead to an eye infection, which is not only painful but could be dangerous. This is especially true for those who wear contact lenses and those with a compromised immune system.

Another reason you should never use an expired mascara is that it can irritate your eyes, leading to irritation and redness. Bacteria can grow on the wand of an old, used mascara.

How To Store Mascara?

When storing mascara, ensure it’s kept in a dry place to maintain its effectiveness. Prevent drying by storing it away from moisture. Refrigerating mascara, especially if infrequently used, preserves its quality and extends its shelf life.

Avoid exposing mascara to air, as this accelerates drying and heightens the risk of bacterial growth, hastening product breakdown. Additionally, always wash your hands before handling eye products to prevent bacterial contamination.


The lifespan of an unopened mascara tube can vary, typically 2-3 years. It is important to consider the expiration date on the mascara tube, as this is a reliable indicator of its shelf life. To extend the lifespan of unopened mascara, storing it in a cool, dry place away from heat, light, and air is crucial. Proper storage can help prevent the mascara from deteriorating, ensuring it remains in good condition when used.

Using a clean mascara wand will not extend the lifespan of unopened mascara, but it is an important step in maintaining good eye health and preventing the growth of bacteria. Overall, it is important to be mindful of the shelf life of mascara, both unopened and in use, to ensure its quality and safety.
