What causes acne?

Acne occurs when pores clog deep inside and form a mild infection, not when you eat greasy foods. http://www.acnetreatmentresults.com/Can_eating_greasy_food_and_a_poor_diet_cause_acne_or_make_it_worse_.html Jul 23 08, 6:52 PM

The root cause of why some people get acne and some do not is not fully known. It is known to be partly hereditary. Other causes include but are not limited to: Family/Genetic history. The tendency to develop acne runs in families. Hormonal activity, such as menstrual cycles and puberty. Inflammation. Stress, through increased output of hormones from the adrenal (stress) glands, although modern tests have said otherwise and point to this not being a cause. Hyperactive sebaceous glands, secondary to the three hormone sources above. Accumulation of dead skin cells. Bacteria in the pores. Propionibacterium acnes (P. acnes) is the anaerobic bacterium that causes acne. In-vitro resistance of P. acnes to commonly used antibiotics has been increasing. Skin irritation or scratching of any sort will activate inflammation. Use of anabolic steroids. Any medication containing halogens (iodides, chlorides, bromides), lithium, barbiturates, or androgens. Exposure to certain chemical compounds. Chloracne is particularly linked to toxic exposure to dioxins, namely Chlorinated dioxins. http://en.wikipedia.org/wiki/Acne#Primary_causes http://www.niams.nih.gov/Health_Info/Acne/default.asp#acne_c Jul 23 08, 8:28 PM
