Chloracne is a rare acne-like skin condition caused by exposure to halogenated
aromatic hydrocarbons (such as dioxins).
Chloracne can start with excessive oiliness of the skin. This leads to the
appearance of whiteheads, blackheads and uninflamed nodules and cysts. Skin may
become thicker, flake and peel.
