The community of microorganisms and their genetic material that inhabit the skin and interact with the skin and its environment.
The skin microbiome includes bacteria, fungi, viruses, and other microorganisms. Its composition varies between different body sites and is influenced by factors such as moisture, sebum, temperature, age, environment, and personal care practices.
These microorganisms can interact with the immune system and with one another and may contribute to skin health or disease depending on the circumstances.
QUICK FACT
A healthy skin microbiome is not a completely germ-free skin surface; many microorganisms normally live on healthy skin.
