Pimples Underlying Cause

The underlying cause of acne is unknown.

Four factors are responsible for the formation of acne:

  • Overgrowth of the skin cells that line the skin pores, which plugs the pore
  • Overproduction of skin oils, which also plug the pores
  • Overgrowth of the bacterium, Propionibacterium acnes
  • Inflammation of the skin

These factors cause the formation of the swollen whiteheads, blackheads and cysts in the skin.
