Lasers in Dermatology
By Patrick Treacy

A laser (an acronym for Light Amplification by Stimulated Emission of Radiation) is a device for producing a beam of intense light which can be controlled and precisely focussed. It works through the conversion of its light energy into heat at specific target points. The high power energy of the laser had been harnessed for use in many fields since the first working model was made by T.H. Maiman in America in 1960.
