The white stuff squeezed out of the black spots on the face is usually a sebaceous plug, which is mainly a white head underneath the blackheads. In fact, blackheads are mainly sebum plugs that are not fully excreted by the ducts of the sebaceous glands of the hair follicles, and the surface of the plugs near the skin is oxidized to black when exposed to the air, so they form black spots. Underneath the black spots are actually sebum plugs, so the white stuff that is squeezed out is actually white sebum plugs, which is the sebaceous fluid secreted by the sebaceous glands and formed after the concentration of the sebum fluid. If this happens, you can apply topical adapalene gel and do not squeeze it with your hands.
