Acne Vulgaris
Acne Vulgaris

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

Background

Cardinal features
�    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

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.
