As the skin ages, red papules of the size of a grain of rice appear on the body in middle and old age, which fade with pressure and are not painful or itchy, and do not require special treatment; 2. In hot summer, due to accelerated blood flow and expansion of superficial skin capillaries, red moles not higher than normal skin can be seen on the skin, which is a normal physiological phenomenon, and will subside after the weather Patients with liver cirrhosis and chronic infection have abnormal liver metabolism and cannot inactivate estrogen in the body, which leads to the increase of estrogen level in the body and makes red moles appear on the skin. It is necessary to actively treat the original disease after diagnosis, and the red nevus can subside after the original disease is cured.
