The emerging role of skin microbiome in atopic dermatitis and its clinical implication

In recent years, the importance of the microbiome in maintaining healthy skin has become apparent. Both the classic microbiology cultivation techniques used since the early 1970s and the next-generation sequencing procedures refined in the past decade reveal the importance of skin microbiome in healthy and diseased skin. To strengthen and eventually restore a healthy microbiome in patients with dermatological conditions like atopic dermatitis (AD), it is important to consider the factors that influence the composition of the microbiome, such as skin pH and skin barrier integrity. Moreover, targeting the microbiome may support established treatment regimens in years to come. Initial studies have generated promising results, suggesting that AD treatments, including select emollients and topical corticosteroids, have a positive impact on the microbiome. This paper reviews different aspects of microbiome in AD and their implications in clinical practice.
