Does deodorant expire? Why natural deodorants may expire faster

Way back in your vanity drawer, there's probably a backup deodorant you can use if you run out ‒ well, when you run out. But does deodorant expire? For those hoping to remain feeling as fresh and clean as they are used to, it's worth paying attention to.

"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," says Dr. Mona Foad, board-certified dermatologist and founder of MONA Dermatology.

What ingredients cause deodorant to expire?

While it might seem like deodorant lasts forever, some ingredients have a shelf life and can impact the efficacy of the product.

"The ingredients most likely to change over time are the fragrance, active ingredients and moisturizing ingredients," Foad says.

The U.S. Food and Drug Administration does not require deodorants to have expiration dates, so many do not. But that doesn't mean they continue to perform as they should indefinitely.

Do natural deodorants expire?

In recent years, "natural" deodorants, such as those that don't include ingredients like aluminum or parabens, have become more popular. Though it might seem like their more plant-based ingredients won't expire, it's actually the opposite.

"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," Foad says.

For example, Native deodorant uses magnesium hydroxide, tapioca starch, shea butter and coconut oil, among other ingredients. Salt & Stone deodorants sometimes use spirulina and lactobacillus ferment for prebiotics and other ingredients.

"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," Foad says. "How you store the product matters too."

How to tell if your deodorant has gone bad

If you don't see an expiration date, and it's been a few years, Foad recommends tossing the product. Other ways to check include:

• Paying attention to whether it's still working effectively or if you need to reapply throughout the day.
• Visually looking for changes to the color or texture, such as the product becoming dry, crumbly, or separated.
• Considering if it's been stored properly in a cool, dry place.

If you aren't sure, you can lean on the adage, "when in doubt, throw it out."
