Brownish-gray and reddish patches, especially on the wrist, upper chest, eyelids, hands, feet, inside the bend of elbows and feet, the face and scalp

There is no cure for this disease. The treatment process of eczema, including both medicines and therapy, only aims to heal the affected portion and control symptoms. Moreover, doctors will recommend medicines depending on an individual’s age, health condition and symptoms. For example, they may suggest creams to control itching and help repair the skin.

Also, doctors provide oral drugs like prednisone which might control inflammation, while antibiotics help reduce infection.

Therapies include:
