Anti-perspirants and foot powder increase the micro-biodiversity of the human body

you've heard a lot about how food affects the body's microbiome, such as probiotics. In fact, human skin is also full of microorganisms, and the beauty products used by people may affect the microorganisms there. The researchers recruited six men
women in a recent study published in BMC. In addition to a small amount of shower gel, the volunteers did not apply any other cosmetics to the skin for the first three weeks. Over the next three weeks, participants used modern "skin care weapons": sunscreen, skin care fluids, sweatkillers and foot powder. Finally, the volunteers resumed their normal lives over the next three weeks. During this time, the researchers collected samples of the volunteers' faces, forearms, armpits and feet for chemical and genetic analysis.
found that lotions and sunscreen did not appear to change the microbiome. But contrary to intuition, anti-sweat and foot powder actually increase the diversity of microorganisms between the armpits and toes. Perhaps because these products change nutrition and moisture, they create conditions and foster a wider range of micro-residents.
also found that different skin care procedures altered the types of hormones and informationals present on the subjects' skin. One day, they assume, personalized skincare recipes can be tailored to individuals - changing people's information in a systematic way to make them more attractive to others, or less attractive if someone wants to "drop the powder."
