The gut is not the only part of the human body that hosts an important microbiome. The surface of the skin is home to a sprawling and complex microbial ecosystem, which interacts with the immune system and influences dermatological health.
The skin contains a diverse microbial ecosystem, which is seeded at birth, but evolves until a person reaches sexual maturity.
The skin is a largely dry and nutrient-poor environment, but some microbes such as Staphylococcus epidermidis and Cutibacterium acnes are able to survive. These skin residents communicate with host cells and help to defend against infection and injury.
