NCCU Researchers Discover Link Between Deodorant, Human Bacteria

Wearing antiperspirant or deodorant doesn’t just affect your social life, it substantially changes the microbial life that lives on you.

New findings by researchers at North Carolina Central University and other institutions finds that antiperspirant and deodorant can significantly influence both the type and quantity of bacterial life found in the “microbiome” of the human armpit.

The work was a joint project by researchers at NCCU, North Carolina State University, the North Carolina Museum of Natural Sciences, Rutgers University and Duke University.      

“We wanted to understand what effect antiperspirant and deodorant have on the microbial life that lives on our bodies, and how our daily habits influence the life that lives on us,” says Julie Horvath, an associate research professor at NCCU and head of the genomics and microbiology research laboratory at the NC Museum of Natural Sciences. “Ultimately, we want to know if any changes in our microbial ecosystem are good or bad, but first we have to know what the landscape looks like and how our daily habits change it.”
