The laser is becoming an increasingly important surgical and medical instrument in the field of dermatology. Developments in the areas of laser technology and application have significantly broadened its clinical use over the past several years. These rapid changes and advances in the use of the laser for cutaneous processes may make it difficult for the physician to maintain a current base of knowledge in this area. Relevant laser systems and their clinical applications are presented and discussed, as are investigational laser systems, which may be of importance for the future. This will allow the dermatologic surgeon the opportunity to update concepts and evaluate the various laser systems and their cutaneous applications.
