Skins is a British teen drama that follows the lives of a group of teenagers in Bristol, South West England, through the two years of sixth form. Its controversial storylines have explored issues such as dysfunctional families, mental illness (such as eating disorders and bipolar disorder), adolescent sexuality, substance abuse, death and bullying. The show was created by father-and-son television writers Bryan Elsley and Jamie Brittain for Company Pictures, and premiered on E4 on 25 January 2007. The show went on to be a critical success as well as a ratings winner within its target demographic. Over its initial six-year run, Skins proved to be atypical of ongoing drama series in that it replaced its primary cast every two years. Plans for a film spin-off were first discussed in 2009, but ultimately did not come to fruition. Instead, a specially-commissioned seventh and final series of the show was broadcast in 2013, featuring some of the cast from its 2007–10 run. The show's name comes from the rolling papers known as "skins".
