Which are the dirtiest parts of our bodies?

Our bodies are covered in billions of bacteria, and while some are good for our skin barrier, others can be troublemakers, contributing to the development of skin diseases. In September 2023, American researchers from George Washington University published a study in Frontiers in Microbiology. It found that our skin hosts its own microbiota, much like our intestines. This microbiota is a mix of millions of viruses, bacteria, and tiny fungi. Interestingly, they noted that the composition of the skin microbiota changes based on whether the skin is dry, moist, or oily. Over four years of studying the skin of 129 Americans, they pinpointed two areas with a high concentration of harmful bacteria. Are we talking about the belly button and armpits?
