The treatment of dry eczema is a long term process, not a disease that can be cured after a few days of treatment, and there is no exact clinical value for the recovery time. Dry eczema, also known as seborrheic eczema, is mainly caused by a decrease in sebum production, loss of skin moisture, and a decrease in the water content of the stratum corneum. The patient’s main manifestation is dry, flaky skin, and in severe cases, even cracks, which occur in the fall and winter months. This disease is more common in elderly people, which is related to the decrease of sebum secretion and the decrease of fatty acid content in the skin, which leads to the decrease of water content of the skin. In addition, if patients bathe too often or use hot water, excessive use of soap, etc. will aggravate the symptoms. The treatment of dry eczema is simple. Patients can use topical moisturizers to increase the hydration of the skin, but it is important to persist. It is recommended that patients use a topical body lotion after each bath, and long-term use can restore the skin barrier function, thus achieving a cure.
