Acne, Pimples, Zit

Acne is a skin condition caused by the over activity of the glands that secrete oily substances (sebum) on to the skin. When there is an increase of sebum, the area around the hair follicles gets clogged up. A bacterium, called Propionobacterium Acnes that normally lives on the skin thrives within the blocked pores. This infection causes inflammation of the skin, which is responsible for the redness and swelling of a spot resulting in acne.

Acne types include:
Papules: Inflamed lesions that are small, pink bumps on the skin and can be tender to the touch.
Pustules (pimples): inflamed, pus-filled lesions that can be red at the base.
Nodules: large, painful, solid lesions that are lodged deep within the skin.
Cysts: Deep, inflammed, pus-filled lesions that can cause pain and scarring.
