Skin Microbiome Composition and Key Factors of its Barrier Function

The skin is the largest organ of the human body, it creates protective barrier between the internal and external environment. Skin barrier damage may result in homeostasis imbalance, inflammation, or bacterial infection. The microbiome plays a crucial role in maintaining normal skin functioning: control of pathogenic diversity of microorganisms, stimulate immune cells, and modulate chronic dermatoses development. There are various mechanisms for restoring skin barrier function. They are associated with the microorganisms’ activity. Thus, skin restoration is an important task included in the general concept of atopic dermatitis management. One of such methods is the skin surface colonization with commensals, so significant role is assigned to the new dermatological drugs. The normalization of the microbiome in affected skin areas with cosmetic care products can significantly affect the result of skin barrier restoration.
