Documentary looking at the physiological and psychological changes that happen to young people as they strive to alter their appearance. Using computer graphics we travel inside the body and explore the science behind the most popular beauty and cosmetic treatments, from a man having the latest hair transplant treatment to revealing what actually happens to our skin as people inject synthetic hormones to achieve the perfect tan. We meet beautician Lucy from Essex who, after losing weight in her teens, wants breasts enlarged to improve her figure, and young bride-to-be Kirsty, who wants to test out Botox before the big day. Through the highs and lows, this is the inside story of how cosmetic surgery works.
