Fresh sweat does not smell. Malodor is caused by microbial transformation into volatiles. To investigate, DrArmpit stuck his nose under more than 1000 armpits and will present some of his main findings. The armpit microbiome and body odor development is influenced by many factors, some of which we can change ourselves. For the really stinky people, DrArmpit came with a new solution: changing the underarm microbiome for a better scent. More than 100 people underwent armpit microbial transplants or bacteriotherapy which resulted in an improved underarm odor. This demonstrates that the right bugs can make you smell great.
