Eczema is an inflammatory disease of the superficial dermis and epidermis caused by a variety of factors that does not usually subside on its own and requires active treatment. The clinical features of eczema are mainly itching, while many clinical symptoms such as erythema, papules, blisters, blisters, vesicles, exudation, keratinization, and crusting appear on the skin surface. Because of itching, patients will unconsciously scratch frequently, thus forming a vicious cycle of itching – scratching – itching, which can easily lead to the transformation of acute eczema into subacute eczema, and eventually into chronic keratosis eczema, which thickens the skin surface significantly. The symptoms on the surface of the skin can be recurrent and persistent, and in severe cases can even last a lifetime, seriously endangering normal life. Therefore, it is recommended that it is best to take the time to treat eczema after it is diagnosed. When you have eczema on the surface of the skin, do not scratch the itchy parts frequently to avoid adverse effects on the effectiveness of the disease treatment.
