Human Skin -Microbiome and Acne.
Research in to microbiomes of the human body , to include skin and gut tell us that a diverse and physiologically important array of bacteria, viruses, fungi and archaea make their home on the skin. Typically, a person has around 1,000 species of bacteria on their skin. And, as might be expected from such a large area — roughly two square metres for an average adult — the skin offers a variety of distinct ecosystems, which create conditions that favour different subsets of organisms. We harbour roughly the same number of microbes as we have cells. This complex ecosystem is crucial to our health, affecting many processes including immunity, child development and bone density regulation. Research in this area has been extensive, with exciting work on how the microbiome develops, its influence on brain and behaviour and implications in both contributing to and treating various disorders.A person’s gut microbiome is seeded in early life according to the bacteria they are exposed to and how successfully these microbes colonise the intestines. Populations of bacteria in the gut are highly sensitive to the food we eat, so sensitive, in fact, that changes in species variation and gene expression appear within three or four days following a major sift in diet.
