Can You Become Immune to Your Deodorant?

Deodorant is one of those products you just need to work. Period. Which is why when you find one that works for you, you stick with it. However, if you’ve ever found yourself in the precarious situation of a (discreet) midday pit sniff yielding unfavorable results, you’re not alone. A quick Google search will confirm that many people experience this strange phenomenon where their tried-and-true deodorant (the one they’ve relied on for years) simply stops working. So, why and how does this happen?

The short answer is we (meaning scientists) don’t really know. The prevailing theory points toward hormones. (Doesn’t it always?) “Hormones fluctuate all the time,” says Dr. Elizabeth Tanzi, founder and director of Capital Laser & Skin Care and Clinical Professor of Dermatology at George Washington Medical Center in Washington, D.C. “It’s not unusual to smell differently with changes in birth control pills, pregnancy, menopause, perimenopause, and when undergoing hormone replacement therapy.” Even if none of those cases pertain to you, your body chemistry does change over time. So it’s not that the deodorant stops working, it’s just that your body has changed and requires something different. 

Time to make a switch? We love Dove’s Clinical Protection Antiperspirant Deodorant ($8) and Degree’s MotionSense Dry Spray Antiperspirant ($7).
