Lasers

Eugenia Mayo Pampín

Abstract

The term laser is an acronym for light amplification by the stimulated emission of radiation. The origins of this technique are in the postulates of Einstein in 1917. In the 80´s the theory of selective thermolysis showed that specific destruction of a target in the skin could be achieved with minimal unwanted thermal injury. The number of indications has increased continuosly, with the improvement in the knowledge of the interaction between light and skin. Vascular and pigmented lesions, tattoos, unwanted hair to be removed, cutaneous aging etc are only examples of the wide spectrum of conditions that can be boarded through LASERs.
