Acne occurs when opening of sebaceous follicles on the surface of the skin become clogged. These holes are called pores.
Each pore opens to a follicle. A follicle contains a hair and an oil gland. The oil released by the gland helps to keep oily skin cells and keeps your skin soft. The glands can become blocked with a mixture or oil and skin cells, the blockage is called a plug or comedone. If the top of the plug is white, it is called a whitehead. It is called a blackhead if the top of the plug is dark. If bacteria is present in the plug, the body's immune system may react to it, causing pimples.
