The symptoms of atopic dermatitis

To atopic dermatitis characterized by recurrent exacerbations with periods that occur during the second reaction to the allergen (e.g., when used in certain food products or in contact with the animal.) The frequency of exacerbations is also influenced by the season of the year (exacerbations are more common in autumn and winter), emotional stress and other factors.
