Skin microbiome is a collection of trillions of organisms that live on the skin. As I have noted, there are many that we do not know about it, but we know that it communicates with our immune system, manages inflammation, protects against environmental stresses, and produces important nutrients for the skin (called postbiotics). We also know that microbiome -making organisms dynam and sometimes change. A lot of things can affect which species live on your skin and dominate, such as your age, hormone, your environment, and more.
