ABSTRACT: Atopic dermatitis (AD) is one of the most common inflammatory skin disorders. Its prevalence has doubled in the past 20 years. It is a combination of genetic factors and environmental factors. The current recommendations rely on an early first-line essential treatment of eczema lesions with dermocorticoids (DC). In case of failure, topical immunomodulators (TI) can be used instead. A daily maintenance treatment with emollients is fundamental to restore the cutaneous barrier. A proactive treatment using DC or TI also prolongs the eczema remissions.
