How to Know Your Deodorant Expired | Featured in USA Today

Did you know that backup, “emergency” deodorant you’ve been keeping at the back of your shelf, is most likely expired? Unfortunately, there comes a time when those backup products need replacing too. As featured in USA Today, Dr. Foad explains how to know when that expiration date has passed.

Can deodorant really have an expiration date?

Yes, deodorant does expire. Over time, the ingredients can break down, which means the product may not work as well as it once did. Most people will use up a deodorant before this becomes an issue, but if it’s been sitting around for years, it’s probably time for a replacement.

What ingredients cause expired deodorant?

The ingredients most likely to change over time are the fragrance, active ingredients, and moisturizing ingredients. Natural deodorants can sometimes have a shorter shelf life because they often contain fewer preservatives and more plant-based oils and waxes. One of the first things people notice is that the product smells or feels different than it did when they first bought it.

When should someone pitch their deodorant?

If there’s an expiration date on the package, I would follow that. If not, take a look at how long you’ve had it. If it’s been sitting in a drawer or bathroom cabinet for several years, it’s probably best to replace it. Even more so if you’ve noticed changes in how it looks or performs.

Are there other ways to tell if deodorant expired?

Yes. One of the biggest clues is that it simply doesn’t seem to work as well as it used to. If you’re noticing odor coming back sooner than normal, or finding that you need to reapply throughout the day, the product may have lost some effectiveness. You can also look for changes in the deodorant itself. If the scent has changed, the color looks different, or the texture has become unusually dry, crumbly, or separated, those are all signs that it may be time to replace it.

Do certain ingredients cause deodorant to last longer?

In general, products that contain preservatives tend to stay stable longer. Natural deodorants may have a shorter shelf life because they’re made with ingredients that can break down more quickly over time. How you store the product matters too. Keeping it in a cool, dry place can help it maintain its quality for longer.
