The relationship between skin microbiota and skin barrier

The skin forms a complex barrier comprising physical, chemical, microbiological, and immunological components. Understanding these dynamics is crucial for effectively treating numerous dermatological diseases.


This review sheds light on the intricate relationship between our skin and its microbial residents, challenging the conventional perception of microbes as passive observers.


Here are some key insights:

  1. Skin microbes play a pivotal role in influencing keratinocyte differentiation and contribute to the formation and maintenance of a healthy barrier.

  2. The skin microbiome appears to affect the cell Junctions (hemidesmosomes, desmosomes and others).

  3. Barrier damage appears to be a common denominator in various chronic inflammatory diseases affecting humans, such as acne and atopic dermatitis.
