I’ve already provided references but here are some more demonstrating that your armpits specifically smell worse because you use deodorants and/or antiperspirants. Do the world a favor and manage your microbiome more conscientiously than this lazy brained approach you’ve taken so far. In short, you stink, but there’s an easy solution to it.
"Overuse of underarm cosmetics is often a flee reaction of people who suffer from malodourous axillae. It is hypothesized in this viewpoint that over usage of these products leads to a selective colonization of malodour-causing microbiota. These bacteria survive in the sweat glands and around the hair roots and are generally more able to withstand the more anaerobic environment. Reference: onlinelibrary.wiley.com/doi/pdf/…/exd.13259
“… an increase in bacteria that compete with odour-generating bacteria may provide a means to reduce body odours without significantly affecting overall microbiota abundance, bypassing the need to use antiperspirants or bactericidal substances.” Reference: …biomedcentral.com/…/s40168-014-0064-3
“Especially when antiperspirants were applied, the microbiome showed an increase in diversity. Antiperspirant usage led toward an increase of Actinobacteria, which is an unfavorable situation with respect to body odor development. These initial results show that axillary cosmetics modify the microbial community and can stimulate odor-producing bacteria.” Reference: researchgate.net/…/Deodorants-and-antiperspirants…
