Abstract
Laser is an energy device capable of emitting light with special features that may be absorbed by the skin. The ability of certain skin molecules, defined as chromophores (e.g., melanin, hemoglobin), to specifically absorb various wavelengths has allowed more and more selective use of laser. Today, it is therefore possible to treat numerous skin and mucosa diseases with excellent esthetic and functional results, reducing healing times and the risk of undesired outcomes (scars and dyschromia).
