Dry skin is mainly characterized by drier skin, less sebum production, flakiness, and flushing or even burning sensation on the face when exposed to external stimuli. Dry skin is characterized by decreased sebaceous gland secretion and skin barrier damage resulting in increased water loss through the sebaceous layer. Its surface skin is relatively thin, acne is rare, and pores are not particularly visible. Dry skin may be caused by congenital or acquired factors that irritate the skin. Dry skin does not usually affect health and therefore does not require special treatment. Patients with noticeable symptoms can be treated with medication under the guidance of a medical professional. It is recommended to choose maintenance and moisturizing preparations without obvious irritation and fragrance, such as vitamin E cream, 10% urea cream or ointment and other medications. Patients need to take good care of their skin on a daily basis. If the situation is more serious, it is recommended that patients go to the hospital for diagnosis and treatment under the guidance of a doctor.
