Eczema is an inflammation of the superficial dermis and epidermis caused by a variety of internal and external factors. Clinically, lesions in the acute stage are dominated by herpes papules with a tendency to ooze, and in the chronic stage, they are dominated by mossy lesions, which are prone to recurrent episodes. Eczema erythema can be eliminated through general treatment, drug treatment, physical therapy and other measures. 1. General treatment: do a good job of skin moisturizing care, avoid scratching and stimulation, eat a light diet, eat more vegetables, while avoiding sun exposure, avoid staying up all night and exertion. 2. Medication: Topical glucocorticosteroids such as mometasone furoate, or calcium strip phosphatase inhibitors such as pimecrolimus can also be used to treat eczema erythema. 3. Physical therapy: Physical therapy with narrow-spectrum medium-wave ultraviolet (NB-UVB) and UVA1 can be used to treat eczema and eliminate erythema. Eczema erythema patients need to go to the hospital in time, follow the doctor’s instructions for treatment, do not use drugs without authorization.
