Book excerpt: Recent research in science establishes a direct relation between human gut and skin. Several species of live microbes inhabit the human skin and intestines which far outnumbers the mammalian cells in the human body. Research interest of Nextgen scientists is focused on beneficially harnessing this microbial population to address skin disorders like acne, rosacea, eczema, premature aging, and skin cancer which are established to be a result of skin-microbiome dysbiosis. This volume highlights evidence-based endeavours of the scientific community in this sector. Currently there is no concrete literature which gives a detailed vision on the relationship between gut microbiota and skin related disorders. This volume is an attempt to put together available data in the area and demonstrate usefulness of probiotics as a new therapeutic option for management of these skin diseases which currently show poor prognosis, high cost of treatment and compromised quality of life of the patient.
