The clear rice grains squeezed out of the face are not mites, but sebaceous plugs secreted by human sebaceous glands. The sebaceous glands secrete sebum to moisturize the skin and hair, which is usually in liquid form. The newly formed sebaceous plugs may squeeze out transparent rice-like material due to the short period of time. With the postponement of time, the sebaceous plugs become white and may be yellow or even black after squeezing with obvious foul odor. Patients should maintain a good mood, avoid spicy diet, moderate consumption of vegetables and fruits, wash face with warm water to keep face deeply clean, and drink more water. In addition, appropriate exercise can be performed to improve the body’s metabolism and enhance physical fitness, which can help prevent sebaceous plugs from forming.
