People have various motivations for using—or avoiding—deodorant and antiperspirant, whether it's to control sweat, eliminate odor, or conform to societal expectations. But if you're someone who uses these products, do you truly understand how they differ?
While their names hint at their functions—deodorant tackles odor, and antiperspirant addresses sweat—there's more to uncover. Here's a deeper look at the distinctions between deodorant and antiperspirant, along with tips on choosing the right one for your needs (if you decide to use them).
How do antiperspirant and deodorant differ, and what should you know about them?
The key distinction between antiperspirant and deodorant lies in their ingredients. Antiperspirants use aluminum-based compounds to block sweat ducts, keeping underarms dry, as explained by Dr. Lucy Chen, a dermatologist at Riverchase Dermatology, in an interview with Good Housekeeping. While they may also reduce odor-causing bacteria, this is a secondary benefit rather than their primary purpose.
In contrast, traditional deodorants work by increasing skin acidity to eliminate bacteria, particularly the type that causes sweat to smell, according to Chen. Dr. Birnur Aral, Director of the Good Housekeeping Institute Beauty Lab, adds that some deodorants use fragrances to mask odors without targeting bacteria. However, deodorants alone do not prevent sweating.
Which should you choose: antiperspirant or deodorant?
Chen states that both are safe for use, and the choice depends on your needs. If you don’t sweat heavily or don’t mind perspiring, deodorant is sufficient. For those with minimal odor but a desire to avoid sweat stains, antiperspirant is a suitable option. Additionally, many products combine both, offering dual benefits for sweat and odor control.
