Most of us use it everyday, but do we know how it works? What does deodorant do to our bodies?
How Advertisers Convinced Americans They Smelled Bad
“In the 1910s deodorants and antiperspirants were relatively new inventions. The first deodorant, which kills odor-producing bacteria, was called Mum and had been trademarked in 1888, while the first antiperspirant, which thwarts both sweat-production and bacterial growth, was called Everdry and launched in 1903.”
Antiperspirant use and the risk of breast cancer
“The rumor that antiperspirant use causes breast cancer continues to circulate the Internet. Although unfounded, there have been no published epidemiologic studies to support or refute this claim. This population-based case- control study investigated a possible relationship between use of products applied for underarm perspiration and the risk for breast cancer in women aged 20-74 years.”
The effect of habitual and experimental antiperspirant and deodorant product use on the armpit microbiome
“The human armpit has long been noted to host a high biomass bacterial community, and recent studies have highlighted substantial inter-individual variation in armpit bacteria, even relative to variation among individuals for other body habitats. One obvious potential explanation for this variation has to do with the use of personal hygiene products, particularly deodorants and antiperspirants.”
