A chronic inflammatory condition of the pilosebaceous unit appearing commonly on the face, back, and chest. Acne may occur as merely inflamed ( as a papule or nodule ) or it may be pustular. In severe cases the lesions are accompanied by cysts ( a sac with acne begins with the blockade of the follicular canal ( blackheads ) and develops through the subsequent leakage of sebum into the dermis. This has an irritating effect, causing an inflammatory reaction and the development of a red papule. Inflammation often leads to the production of pus which forms a pustule or “pimple”.  Acne is fundamentally an inflammatory reaction to the presence of sebum as a foreign substance in the dermis. Bacteria may, at a larger stage, cause infection.

For reasons no one completely understands, follicles, often called pores, sometimes get blocked. Sebum (oil) which normally drains to the surface gets blocked and bacteria begin to grow. Both whiteheads and blackheads start out as a microcomedone

Acne, like comedone is most prevalent during adolescence, when heightened androgenic activity stimulates sebaceous excretion. People with oily skins usually have the worse problems. Diet is not a cause, but for many people certain foods, particularly chocolate, can worsen an acne condition. Mental stress can also aggravate acne. In girls there is usually an increase in acne prior the menstruation.

Even though, not associate with hair follicle, removal of unwanted hairs in an acne prone area will definitely clear the skin condition by simply drying the hair follicle’s  region therefore improving significantly  the skin texture.
