In recent decades, the use of sophisticated technologies, including laser technology, has made it possible to repair skin tissue defects that are difficult to treat.  There is a spectrum of laser and light technologies available for skin resurfacing and rejuvenation.  Laser light can be accurately focused into small spots with very high energy. The aim is to destroy the target cells and not harm the surrounding tissue.  

The energy released by laser radiation can leave the most superficial skin layers unharmed and selectively hit only certain targets located deeper down. Melanin, haemoglobin and exogenous pigments can be destroyed selectively and the production of new collagen can be achieved.

There are several types of lasers used in skin laser surgery.  The wavelength peaks of the laser light, pulse durations and how the target skin tissue absorbs them determine the clinical applications of the laser types.
