Lasers: state of the art in dermatology.

The unique properties of lasers create an enormous potential for specific therapy of skin diseases. As with any new device, the most efficacious and appropriate use requires an understanding of the mechanisms of light interaction with tissue as well as the properties of the laser itself. Modification of current lasers and innovative advances with biomedical laser instrumentation may eventually allow the physician to match optimally the laser and the treatment procedure with the lesion.
