imagesAcne vulgaris is commonly called acne. It is a common skin condition caused by changes in the pilosebaceous units, structures of the skin consisting of a hair follicle and sebaceous glands associated with it via an androgen stimulation. It is characterized by papules or follicular non-inflammatory comedones and by inflammatory papules, pustules and nodules in its more severe forms. Acne vulgaris affects areas of skin with the largest population of sebaceous follicles, these areas include the face, upper chest and back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms. Acne lesions are commonly known as pimples, spots, spots, zits, or just acne.

Acne occurs most often during adolescence, affecting more than 89% of adolescents, and often continues into adulthood. In adolescence, acne is usually caused by an increase in male sex hormones, that people of both sexes to run during puberty.   For most people, acne diminishes over time and tends to disappear or at least decrease-after one reaches his twenties. However, it is impossible to predict how long it will take to disappear entirely, and some individuals will handle this condition well into their thirties, forties and beyond.

The face and upper neck are the most frequently affected, but the chest, back and shoulders May have acne too. The arms may also have acne, but lesions found there are often keratosis pilaris, not acne. Typical acne lesions are comedones, inflammatory papules, pustules and nodules. Some of the large nodules were previously called “cysts” and nodulocystic term has been used to describe severe cases of inflammatory acne.

In addition to scarring, its main effects are psychological, such as decreased self-esteem and, according to at least one study, depression or suicide. Acne usually appears during adolescence, when people already tend to be most socially insecure. Early and aggressive treatment is therefore advocated by some to reduce the overall impact of individuals.
