Fighting bacteria: Each hair follicle is connected to a sebaceous gland. The sebaceous glands produce sebum, which keep the skin surface oily and protects the skin. The importance of adequate face washing: when dead skin clogs up a pore, bacteria grows in the oily skin. The whiteness of an acne lesion is the pus formed by the dead white cells that fight the acne bacteria.
