Overview
Acne Vulgaris is a skin disease, caused by changes in the pilosebaceous units (skin structures consisting of a hair follicle and its associated sebaceous gland). Severe acne is inflammatory, but acne can also manifest in noninflammatory forms.[1] Acne lesions are commonly referred to as pimples, spots, or zits. For most people, acne diminishes over time and tends to disappear, or at least decrease, after one reaches his or her early twenties. There is, however, no way to predict how long it will take for it to disappear entirely, and some individuals will continue to suffer from acne decades later, into their thirties and forties and even beyond.[2]
The term acne comes from a corruption of the Greek άκμή (acme in the sense of a skin eruption) in the writings of Aëtius Amidenus. The vernacular term bacne or backne is often used to indicate acne found specifically on one's back.[3]
Classification
There are multiple grading scales for grading the severity of acne vulgaris.[4] Three of these techniques include the Leeds acne grading technique, which counts and categorizes lesions into inflammatory and non-inflammatory (ranges from 0-10.0), Cook's acne grading scale, which uses photographs to grade severity from 0 to 8 (0 being the least severe and 8 being the most severe), and the Pillsbury scale, which simply classifies the severity of the acne from 1 (least severe) to 4 (most severe).
Epidemiology and Demographics
In the United States, acne affects 17 million people. It is most common during adolescence, affecting more than 85% of teenagers, and frequently continues into adulthood. [5]
Risk Factors
Acne is the most common skin disease. People of all races and ages get acne. But it is most common in teenagers and young adults. An estimated 80 percent of all people between the ages of 11 and 30 have acne outbreaks at some point. Some people in their forties and fifties still get acne.
