The continual development and dissemination of laser technology throughout the world has been nothing short of miraculous. Over the last fifteen years, this field has been marked by constant technological innovation. This book represents the most up-to-date description of the state of the art in laser and light source technology. Its authors represent leading experts from both North America and Europe. After an initial chapter describing the latest understanding of laser physics and safety, subsequent chapters take up laser treatment of vascular lesions, pigmented lesions and tattoos, unwanted hair, ablative and non-ablative resurfacing, and its use for medical purposes. Each chapter begins with the core concepts historically followed by laser treatment for a given cutaneous problem, currently available technologies, indications, and contraindications. Each author then provides an example of his/her consent form and personal treatment approach.
