The white grains squeezed out of the pores are not mite feces, but sebum. The sebaceous glands on the face secrete sebum and the sebaceous ducts open to the hair follicles. The size of the mite is very tiny, around 0.5 mm, and it is not visible to the naked eye, much less its feces that can be observed by the naked eye. The sebum squeezed out of the pores is due to excessive sebum secretion, frequent late nights, long time eating spicy, stimulating, greasy food and genetic factors can lead to high sebum secretion. Normally, you should do a good job of facial cleaning and care, try to wash your face with warm water, pay attention to hydration, and avoid squeezing the hair follicles with your hands to avoid inflammatory reactions. Pay attention to a light diet and avoid greasy and stimulating foods.
