Oil Glands

Sebaceous glands are attached at the base of each hair follicle. The process of inflammation is contributed to by changes in the skin which lines the hair follicle. During puberty and young adulthood, the skin cells of the hair follicle lining shed more quickly, in clumps, and are sticky, and this is a main contributor to the clogging of pores. The blocked, oil filled follicle also contain a bacteria called Propionibacterium acnes (normally present) which multiplies once trapped within a pore and results in redness, inflammation, and a pustule.
