What causes acne
In normal skin, oil glands under the skin, known as sebaceous glands, produce an oily substance called sebum. The sebum moves from the bottom to the top of each hair follicle and then spills out onto the surface of the skin, taking with it sloughed-off skin cells. With acne, the structure through which the sebum flows gets plugged up. This blockage traps sebum and sloughed-off cells below the skin, preventing them from being released onto the skin’s surface. If the pore’s opening is fully blocked, this produces a whitehead. If the pore’s opening is open, this produces blackheads.
