Factors influencing the composition and function of the human skin microbiota and its function. The skin microbiota is shaped by numerous factors: extrinsic (such as lifestyle that embodies occupation, hygiene routine, use of drugs and cosmetics) and intrinsic (genetics, aging, sex, site of the body, etc.) These factors influence the roles of the skin microbiota, implying protection against potential pathogens or climate perturbation as well as the maintenance of skin integrity.
