Barrier defect in atopic dermatitis - possibilities and limits of basic skin therapy

Abstract

The increased permeability of the skin barrier towards environmental factors such as allergens is considered a key factor in the pathogenesis of atopic dermatitis (AD). Strengthening the skin barrier through basic skin therapy represents the basis of any therapy for AD. It is well known that genetic factors as well as the skin inflammation itself contribute to the weakening of the barrier; here, recent studies have led to a deeper understanding of the complex structures of the epidermis. The possibility of counteracting the disease preventively by the use of basic skin therapy from birth on has been studied intensively in recent years. This article summarizes recent findings on the effects of basic skin therapy as a primary and secondary preventive measure.
