Lasers and Energy‐based Devices

Nazanin Saedi, Christopher B. Zachary


Laser and light therapies have offered significant advances in dermatological therapy in the past several decades, having evolved significantly from the early use of the ruby laser in 1960 to the current time when such technologies have become a mainstay of treatment for a host of medical and surgical conditions. The chapter covers laser‐, light‐ and energy‐based devices and their applications for aesthetic purposes. Given the large number of devices available, it is essential for the laser surgeon to understand their capabilities and limitations. In order to provide patients with optimal treatments, the laser surgeon needs to accurately identify the target structure, select an appropriate laser‐ or light‐based system, and then tailor the specific parameters for the intended target.
