The altogether good to excellent clinical response of acne lesions and acne scars, with a low side effect profile, warrants further study of this simple, modified treatment regimen in patients with acne and acne-induced scarring.

An increasing number of healthy individuals make use of 'lifestyle' drugs, such as nootropics, psychopharmaca, hormones and eco-drugs. In this respect, the fact that many people try to improve their outer appearance, solve their 'cosmetic problems', influence their rate of hair growth and altogether delay, halt or even reverse the natural ageing process has become a relevant matter for the practising dermatologist. Lifestyle drugs in dermatology are taken in an attempt to increase personal life quality by means of attaining a certain, psychosocially defined beauty ideal. They are not taken to manage a medically identifiable, well-defined disease. Often, patients suffering from somatoform disorders, such as hypochondriac disorders, body dysmorphic disorders, somatization disorders or persistent somatoform pain disorders, may spontaneously ask physicians, in particular dermatologists and plastic surgeons, to prescribe them lifestyle drugs. Typically, patients repeatedly present with alleged 'physical symptoms' that turn out to be subjective complaints without any underlying identifiable medical disease. The use of lifestyle drugs without any proper medical indication may lead to a chronification of the emotional disorders that had ultimately been the cause of the patients' request for such drugs. Such disorders may need to be treated promptly with psychotherapy and/or appropriate psychopharmacotherapy, and the choice of the treatment requires an accurate differential diagnostic approach.

Even in dermatology one can potentially encounter suicidal patients. A risk of suicide can be preexisting, appear as complication of skin disorders or be triggered by medications such as interferons. Patients at risk must be specifically asked about suicidal ideations and tendencies. Acute suicide risk requires immediate crisis intervention. In dermatology suicide risk has been described in severe acne conglobata (especially men) and metastatic melanoma. Patients with chronic or potentially fatal disease or severe pain may be suicidal. In addition patients with depression, alcohol dependency, substance abuse, schizophrenia or borderline personality disorder are at special risk. We review psychodermatological diseases with risk of suicide and point out treatment strategies. More attention should be focused on the early recognition of a possible risk of suicide in dermatology patients.
