The cause of eczema is not clear and symptomatic treatment is often administered. Various suspected causative factors need to be avoided, such as avoiding spicy and irritating foods, alcohol consumption and excessive scalding during the onset of the disease. The choice of eczema medication varies from period to period. Eczema is divided into acute, subacute and chronic phases. In the acute phase, no exudate or little exudate, corticosteroid creams are available. In the subacute stage, corticosteroid emulsions and pastes are available. In the chronic phase, hard creams and ointments are used. If there is secondary infection, anti-inflammatory treatment with antibiotic ointment is required. Some eczema creams contain herbal ingredients to cool, relieve itching and reduce inflammation. It is important to note that corticosteroid ointments should not be applied over a large area, as they have similar effects to oral hormones when absorbed by the skin, and care must be taken for the elderly and children. Thin and tender skin, such as the face and folds, should not be used for a long time with hormone creams. If the face is used for a long time, it will cause hormone dependent dermatitis, when the face will have redness, itching and stubborn symptoms. It is very difficult to treat this kind of patients, basically each patient needs 1 year to treat, so you must be psychologically prepared.
