The skin microbiome refers to the diverse community of microorganisms, including bacteria, fungi, and viruses, that live on the surface of the skin. These microbes play a crucial role in maintaining skin health by protecting against harmful pathogens, regulating the immune system, and contributing to skin barrier function. A balanced skin microbiome can help prevent skin conditions such as acne, eczema, and psoriasis. Factors like diet, hygiene, and environment can influence the composition of the skin microbiome, highlighting the importance of understanding these interactions for overall skin health.
