Illustration of a sebum plug (clear) and dead skin cells (red) blocking the pore from a hair follicle at the surface of the skin. Sebum, produced by sebaceous glands within the skin, is an oily substance that lubricates and protects the skin. Overproduction of sebum can lead to blocked pores, which allow bacteria present to multiply, causing inflammation and a pimple or pustule. | |
