The epidermal barrier in atopic dermatitis.
Epidermal barrier function is abnormal in individuals with atopic dermatitis (AD). It is controversial whether primary epidermal barrier abnormalities alone account for the physiological and clinical abnormalities found in those persons with AD or whether the observed barrier dysfunction is a consequence of primary immunologic abnormalities. Recent evidence is strengthening the argument for the former hypothesis. Attention to epidermal barrier care (ie, gentle skin care) has long been an important part of the therapy of AD. Advances in our understanding of the biology of the epidermal barrier and how this relates to the clinical manifestations of this disease has important consequences for new therapeutic approaches in the management of AD.
