The Coolest Way To Make Your Makeup Last Is In The Refrigerator

Not knowing how long you've been using a tube of mascara or cheek stain is just as bad as making one of these makeup mistakes (in our opinion). Applying old makeup can expose you to toxins and bacteria that can make you sick or cause skin irritations. So how exactly can you extend the shelf life of your favorite beauty products? Keep them cool.

In the video above, PopSugar Beauty reporter Kirbie Johnson explains how storing certain cosmetics in the refrigerator next to your fruits and veggies can help them last longer. When your makeup or skincare products get too hot, the ingredients break down and they are no longer as effective.

We've all seen what happens when nail polish sits too long and the color and texture begins to muddle. Store your lacquers in a Tupperware and place them in the fridge to stop them from turning thick. Eye creams and moisturizers are also better preserved in the refrigerator, and the cool temperature will amp up the soothing sensation. However, it's best to keep your perfumes in a cool, dark place such as your medicine cabinet for a truly fresh and aromatic experience.

Watch the video above for the complete guide on how to make your makeup last.
