The Microbial Ecosystem on Our Skin
The human body hosts a vast and complex ecosystem of microorganisms, with over 100 billion bacterial cells residing on our skin. These microbes play vital roles, contributing to body odor and other skin characteristics while also being involved in our overall health. For instance, certain bacteria are essential for producing natural scents and maintaining skin health, despite their sometimes unappealing origins.
