Acne - What Causes It?

Many individuals suffer from acne, not just adolescents. Acne is caused by normally occurring bacteria, Propionibacterium acnes. This bacterium gets trapped in plugged skin pores or follicles, especially in the face. In an attempt to escape, the bacterium produce enzymes used to break down the sebum (the excretion produced by sebaceous glands) blocking the escape routes. When the enzymes go to work one of the side effects is inflammation in the area.

Light to moderate cases of inflammation show up as pimples and bumps. This type of acne is known as superficial acne. If the inflammation is deeper within the skin and pores, resulting in cysts and nodules, it is called cystic acne.
