The Role of the Skin Microbiome in Health and Disease.

Abstract

Human skin acts as a barrier between the body and the outside environment, preventing disease-causing organisms and foreign substances from getting into our body. The skin also serves as an ecosystem for billions of microorganisms, collectively called the skin microbiome. Some of these microorganisms are merely bystanders, while others work together with the skin to fight invaders or promote immunity. While knowledge of the skin microbiome lags behind that of the gut microbiome, there is growing evidence that microbial imbalances on the skin are associated with skin disorders and chronic wounds.
