ACNE DEFINITION, TYPES, CLASSIFICATION

Definition
Acne can give rise to a multi-factorial skin disease caused mainly of the sebaceous gland follicle, the first non-inflammatory comedones produces ("blackheads"), but also later in inflammatory lesions such as papules, pustules and nodules. The most important criterion is the presence of acne comedones.

Acne is usually harmless and occurs mainly in adolescents. An estimated 70 to 90 percent of teenage acne lesions indicate, however, develops only in about 10-30 percent of clinical acne that requires treatment. With more than 70 percent of the disease is mild. Acne occurs mainly between the 15th and 18 Age on (mostly in boys than in girls and later) and is considered a "social disease".

The term acne comes originally from the Greek "akme" of ("peak ripeness, bloom"). By a faulty transcription of it was the Latin term "acnas". In English, the acne as "rosy-drop" was called, which means something like "flower". This designation is due to the pointed shape of the pustules. The translation from English into German occurred in the nineteenth century.

Acne forms on the extent and severity
On the extent and severity of acne comedones the distinction is that acne papulo-pustulosa and acne conglobata. In light of acne comedones occur mainly comedones and a maximum of only very few, mild inflammation (papules) in the T-zone (forehead, nose and chin) on. The skin is coarse and slightly shiny and greasy. They usually heals without a scar from forming. Acne Papulopustulosa characterized by papules and pustules, which can lead to scarring. You are not only the face, but also in the range of cleavage, upper arms, chest and back. The most severe form is acne conglobata. In their form also called, sometimes painful, and Fistelkomedonen nodes, a strong scarring is possible.
Acne forms on the cause

On the basis of their skin disease can cause acne in an endogenous, exogenous, which sometimes run extra, drug-induced and physically induced acne can be divided, where different forms of acne and special shapes can be assigned.

Endogenous Acne
For acne include endogenous forms that have their origins in changes in body metabolism.

Acne Vulgaris
Acne vulgaris ("common acne", "puberty acne") is the most common endogenous form of acne and is therefore represented here in some detail. It is caused by hormonal changes in the body. During puberty, the concentration of male sex hormones (androgens) in the blood, but boys are more frequent and more affected by the impacts (girls especially during the menstrual cycle and during pregnancy). The hormones cause an increase or increased production of sebum, which can lead to a disorder of keratinization in the output of the sebaceous gland follicle when the sebaceous glands become clogged by skin cells and sebum can not flow out of. As a result, form comedones (dark-colored by the skin pigment melanin) to the case of a possible inflammatory papules, pustules or nodules lead. Mainly affects skin areas with many sebaceous glands, such as face, shoulders, neck, back, neck, shoulders less frequently, genital, buttocks and groin. In today's medicine can be the often harmless and mild acne vulgaris running pretty good deal, unless it is started early enough therapy in the dermatologist. Stakeholders can assist with an appropriate cleansing and skin care treatment. A small consolation is that the acne will disappear by the end of puberty alone, usually at the very latest by the beginning of the third decade of life.
