Acne is an inflammatory disease of the sebaceous glands (oil producing) and hair follicles of the skin that is marked by the eruption of pimples or pustules, especially on the face.
Acne is considered a normal response to abnormal levels of the male hormone testosterone.
An increase in oil secretions may build up beneath a blocked pore, allowing bacteria (including Propionibacterium acnes and yeast) to increase in number and cause inflammation.
More than four out of five people between the ages of 12 and 24 develop acne at least once in their life. It usually affects individuals in puberty, but can affect people of any age.
Women may experience mild to moderate acne due to hormonal changes associated with feminine health issues, such as pregnancy, menstrual cycles, menopause, or starting/stopping birth control pills.
Acne may cause scarring, so care should be taken to reduce the chances of this happening, such as using autologus (from patient's body) fat transfer, dermabrasion, collagen injections, laser treatments, and vitamin E oil.
