The establishment of microbial communities on the skin’s surface, a process where microorganisms, including bacteria, fungi, and viruses, occupy and proliferate on the cutaneous layer, is a naturally occurring phenomenon. This resident microbiota plays a crucial role in maintaining skin health. For instance, some bacteria produce substances that inhibit the growth of harmful pathogens, contributing to the skin’s defense against infection.
A balanced skin microbiome is essential for overall well-being. It contributes to immune system development, wound healing, and protection against environmental stressors. Historically, understanding this complex ecosystem has evolved significantly, moving from basic observation to advanced molecular techniques that allow for detailed characterization of the microbial communities and their functions. This improved understanding has led to advancements in dermatological practices and treatments.
