When you squeeze the pores on your face and white stuff comes out, this may be sebum secreted by the sebaceous glands, which is usually caused by overproduction of sebaceous glands. If the sebaceous material normally secreted by human sebaceous glands is not discharged to the surface of the skin effectively, it will be easily concentrated around the pores of hair follicles, and to a certain extent, it will form sebaceous plugs. The sebum plugs accumulate at the mouth of the hair follicle, and when squeezed with external force, the white sebum plugs will break through the original blocked hair follicle mouth and be discharged out of the body. If the material is gray or black, it may be due to the oxidation of the plugs, which normally does not affect daily life. Usually you can use mild and clean cleansing products to clean your face, pay attention to face moisturizing; do not squeeze the pores when washing your face to avoid making the pores more coarse. At the same time, you should maintain a light diet, drink more water, and avoid spicy and stimulating foods.
