title: [Induced acne].
abstract: Induced acne belongs to the clinical forms of acne. Some dermatoses present with acne-like patterns. They can be induced or perpetuated by non physiological factors. Among these factors, medicines must always be considered, taken either topically (dermocorticoids, sulfur, anti-acneic topics) or generally (androgens, oral corticoids, ACTH, anti-epileptics, anti-depressive drugs, anti-tuberculosis medications). Halogens (iodine, bromine) found in inhaled or orally taken pharmaceutical products, or associated with occupational contact, can also induce acne. Acne of exogenous origin has been described in some specific occupations, and are induced by exposure to chlorine, industrial oils, tar. Sun exposure, PUVA therapy and ionizing radiation are potentially acneigenous. Finally acne caused by cosmetics includes acne cosmetica, brilliantine and oily creams acne and detergent acne.
