Acne

Acne vulgaris (acne or) is a common skin disease characterized by areas of human skin with seborrhea (flaky red skin), the collapse of (blacks and whites), pimples (pinhead), pustules (pimples) nodules (larger bumps) and possibly scarring. Acne affects mainly the skin densest population of sebaceous follicles, these areas are the face, upper chest and back. severe acne is inflammatory, but acne can also manifest in noninflammatory forms.The consequential changes in the pilosebaceous units, the skin structures consisting of the hair follicle and its associated sebaceous gland, changes that require androgen stimulation.

Acne occurs most often during adolescence and often continue into adulthood. In adolescence, acne is usually caused by an increase in male sex hormones, as people of both sexes run during puberty. For most people, acne diminishes over time and tend to disappear - or at least reduce - after reaching your early twenties. However, there is no way to predict how long it will take to disappear completely, and some people will bring this condition and in their thirties, forties and beyond.

Some large nodules previously called cysts and the term used to describe nodulocystic severe cases of inflammatory acne. Blister or bubbles, which included cystic acne can appear on, buttocks and groin armpits and other places where the sweat accumulates in hair follicles and sweat ducts. Cystic acne affects deeper skin tissue that is common acne.

Except for the scars, its main effects are psychological, such as low self-esteem and, according to at least one study, depression or suicide. Acne usually occurs during adolescence, when people already tend to be socially insecure. The early and aggressive treatment is therefore advocated by some to reduce the overall impact of individuals

Cause

Acne develops as a result of blockages in follicles. Hyperkeratinization and the formation of a plug of keratin and sebum (a microcomedones) is the first change. The enlargement of the sebaceous glands and sebum production occur with greater increase in androgens (DHEA-S) production of adrenarche. The microcomedones may enlarge to form an open comedo (blackheads) or closed comedo (milia). The black dots are the direct result of "plugging the sebaceous glands with sebum, a natural oil, and dead cells. In these circumstances, the natural commensal bacteria Propionibacterium acnes can cause inflammation widely, leading to inflammatory lesions in the dermis through the microcomedones or comedo, which results in redness and may result in scarring or hyperpigmentation.

Genetic

Tendency to develop acne runs in families. For example, children of school age acne often have other members of their family with acne as well. family history of acne associated with an event earlier in acne and acne lesions increased retentional
