From anti-aging to Botox and cosmetic surgery: one of the most controversial areas of medicine has become a multimillion dollar business. But interventions of this kind can frequently have devastating results. Let's face it: in many countries, any doctor can call themselves a cosmetic surgeon without requiring specific qualifications. And surveys reveal that one in four patients is unhappy with the outcome. In collaboration with doctors, Hans Weiss and Ingeborg Lackinger Karger describe and assess the central techniques and procedures offered by the beauty industry. What is useful? What is damaging? What is just a waste of money? And which doctors should you really steer well clear of? By way of example, a whole chapter is dedicated to a prominent cosmetic surgeon and his dubious business practice in Germany.
