Importance of the skin microbiota in skin health

There are millions of bacteria, fungi and viruses that live on the skin and fight daily to protect the body from external aggressors. We present them to you here.

What is the skin microbiota?

The term microbiota refers to a community of living microorganisms belonging to a specific ecological niche, made up of stable species and other transient ones. It is essential for the body and maintains a symbiotic or mutually beneficial relationship with the human body.

Resident skin microbiota

They are microorganisms called commensals, since they survive at the expense of the host without causing diseases. In general, they are responsible for attacking foreign germs that try to steal their nutrients or replicate. The most common are Staphylococcus epidermidis and Malassezia spp.

Transient skin microbiota

This flora temporarily establishes itself on the skin depending on the environment, weather conditions and daily activities. They are usually harmless microorganisms, mainly saprophytes, that feed on decomposing matter.

Importance of the skin microbiota

The microflora of the skin is part of the first defense barrier of the human body against external aggressions and pathogens. Currently, studies affirm that there are microorganisms that actively participate in alerting the immune system of potential infections.
