Abstract:
Acne is a common skin disease in adolescence. It is a chronic inflammatory disease of the pilosebaceous units, which mainly occurs on the face and upper parts of the trunk. Based on severity of the lesions, acne can be mild, moderate or severe. Severe acne is usually featured with a protracted course and residual scars. Photodynamic therapy (PDT) has been demonstrated to be effective in severe acne recently. We report a case of monozygotic twins with severe acne who were successfully treated with PDT.
