Minute to Understanding: What is the skin microbiome?

The trillions of bacteria, fungi and viruses that live on the skin all over our bodies is part of the microbiome. 

So think about your skin. It's not just the same all over, right?

We have oily sites like our face, our scalp, our torso. We have dry skin like our hands, our forearms. And then we have moist skin like our feet and our armpits. And correspondingly what we found is that our skin's microbiome, which are the trillions of bacteria, fungi, and viruses that live on our skin and really actually all over our bodies is different based on these different skin properties. And so why is the site specificity of our skin and its microbes important?

Well, we know that skin disease also occurs in this site specific manner. So we get acne on our face. We get foot fungus or jock itch. We get eczema in our arm and leg creases or warts at different sites. And so understanding the different ways that our microbes interact with our skin will help us understand how to make targeted therapeutics that are specific to our skin where the microbes at that particular site. And so that's a minute to understanding the skin microbiome.
