Acne, medically known as Acne Vulgaris, is a skin disease that involves the oil glands at the base of hair follicles. It commonly occurs during puberty when the sebaceous (oil) glands come to life - the glands are stimulated by male hormones produced by the adrenal glands of both males and females
Description� Acne vulgaris is a common skin disorder
� Chronic disease of sebaceous follicle, primarily affecting face, chest, and back
� Onset typically occurs at puberty because of increased sebum production triggered by increased androgen levels, but may persist throughout adulthood
� Inflammation is due in part to over-proliferation of Propionibacterium acnes, an anaerobic Gram-positive organism that resides in follicles
� Classified on basis of type of lesions (comedonalnoninflammatoryvs inflammatory) and number of lesions present
� Disease of pilosebaceous unit (sebaceous follicle), primarily affecting face, chest, and back
� Onset typically occurs at puberty because of increased sebum production triggered by increased androgen levels. Virtually all adolescents will be affected to varying degrees
� Comedonal lesions are caused by obstruction of the pilosebaceous unit
� Follicular disruption then leads to inflammatory lesions (papules, pustules)
� Scarring may result
� Treatment is based on type of lesions and number of lesions present
Industrial exposure to halogenated hydrocarbons.
� Adrenal hyperplasia
� Polycystic ovarian syndrome
Contributory or predisposing factors
� Hair greases or oil-based cosmetics
� Sports equipment such as helmet straps rubbing and occluding skin
� Medications with iodine (found in some cough medicines)
� Some prescription drugs: lithium, isoniazid, phenytoin, corticosteroids, anabolic steroids, and oral contraceptives with high androgenic activity
� Chemotherapeutic agents that act on epidermal growth factor receptors
� Excessive milk intake, especially skim milk, in teenagers
There are various types of pimples� Whiteheads - remain under the skin and are very small.
� Blackheads - clearly visible, they are black and appear on the surface of the skin. Remember that a blackhead is not caused by dirt. Scrubbing your face vigorously when you see blackheads will not help.
� Papules - visible on the surface of the skin. They are small bumps, usually pink.
� Pustules - clearly visible on the surface of the skin. They are red at their base and have pus at the top.
� Nobules - clearly visible on the surface of the skin. They are large, solid pimples. They are painful and are embedded deep in the skin.
� Cysts - clearly visible on the surface of the skin. They are painful, and are filled with pus. Cysts can easily cause scars.
