These areas of skin have the most oil (sebaceous) glands. Acne occurs when hair follicles become plugged with oil and dead skin cells. Hair follicles are connected to oil glands. These glands secrete an oily substance (sebum) to lubricate your hair and skin.
Acne occurs when the pores of your skin become clogged, most often on the face, neck, back, and chest. Once a pore becomes clogged, it traps skin oil inside. Bacteria grows in this oil and can cause an inflammatory response in the skin. Acne lesions can be small and hardly noticeable, have a small white or black head, or can appear red with a white/yellow center.
