title: [Pathophysiology of acne. What is confirmed?].
abstract: Acne is the most common skin disease worldwide. Choosing the appropriate therapeutic regimens for the clinically diversified disease phenotypes require good knowledge of its pathophysiology. New concepts in this field have been developed in the last 15 years. Acne vulgaris is an inflammatory disorder in which androgens, PPAR ligands, regulating neuropeptides and environmental factors are probably involved as triggers. These factors interrupt the natural cycling process in the sebaceous gland follicle and support the transition of microcomedones to comedones and clinically inflammatory lesions. Proinflammatory lipids, chemokines and cytokines overtake the role of mediators for the further development of acne lesions. Bacterial antigens can potentate the inflammatory phenomena.
