How does sweating affect acne
Forms of late acne
In the following, the types of acne are classified according to their triggers. It is possible that they also occur below adulthood, for example drug or cosmetic acne as well as occupational acne in young people in training. Identification of the triggers and consistent treatment are always necessary to prevent chronification and scarring.
Androgenetic acne in women (acne androgenetica)
This form of acne mainly occurs in women in their third or fourth decade of life. Because of a hormone imbalance, which can be caused, for example, by ovarian dysfunction or by physiological hormone fluctuations during pregnancy and breastfeeding, the androgen effects in the area of the hair sebum follicles are increased. More or less inflammatory nodules (papules) and increased sebum production (seborrhea) are typical. In contrast to acne vulgaris in adolescence, the skin symptoms manifest themselves predominantly in the area of the chin and upper neck (submandibular region), often worsen premenstrually and can persist for a long time without treatment.
This form is induced by various contact substances with comedogenic effects. The most important are petroleum (for workers in oil fields and refineries), tar (for road workers, roofers), lubricating oils and greases (for auto mechanics) and chlorinated hydrocarbons (for workers in the electrical industry). When working outdoors, UV exposure can be an additional trigger factor. The localizations of the skin symptoms are different; For example, tar acne often leads to black-colored inflammation of the hair follicles in the area of the forearms and thighs. In standard dermatological works, occupational acne, like the cosmetic acne described below, is one of the contact acne (acne venenata, from Latin venenum = poison).
Cosmetic acne (Acne cosmetica)
The triggering factors for this form of acne are excessive use of cosmetics with comedogenic ingredients (e.g. lanolin, petrolatum, sodium lauryl sulfate).
Malignant acne (acne fulminans)
In this form of acne, in addition to severe skin changes (e.g. deep-seated, inflamed, purulent nodules), joint inflammation, liver and spleen swelling, high fever and severe general symptoms occur. It also often occurs in young males. Inpatient treatment may be necessary.
Mallorca acne (spring acne, summer acne, acne aestivalis)
It arises - mostly on the basis of a genetic predisposition - through intensive UV radiation and / or the use of fatty sunscreens. There is redness, itching, nodules, pustules or papules in sun-exposed areas, i.e. especially on the neck, décolleté, chest, shoulder or back. The symptoms usually subside spontaneously in autumn.
Mechanical acne (acne mechanica)
In this form, acne vulgaris is aggravated by mechanical irritation such as B. Abrasion stimuli. In the areas of the body (chest, back, buttocks, chin, etc.) where these stimuli act, invisible microcomedones initially form as precursors of the typical blackheads. Examples of triggers are clothing (e.g. shirt collars, turtlenecks), straps (e.g. from backpacks, loads or helmets) or seating (chair backs, car seats). A sub-form of acne mechanica is tropical acne (acne tropicalis), which can break out in tropical climates, especially in men with a history of acne, if there is additional mechanical irritation (e.g. from carrying items of luggage, tight clothing).
Medicinal acne (Acne medicamentosa)
This term is used both for drug-induced acneiform skin changes and for pre-existing acne that is aggravated by drugs. After stopping the drug, it usually disappears. The most important active ingredients that can cause acne or acne-like skin changes include glucocorticoids (steroid acne), anabolic steroids ("doping acne"), tuberculostatics (e.g. isoniazid), lithium, antibiotics (tetracyclines, streptomycin), potassium iodide, B vitamins (B.1, B6, B12), Ciclosporin A and EGFR blockers (Gefitinib, Cetuximab).
