Lasers offer a unique way to treat various medical and cosmetic skin problems with minimal pain and invasiveness. The term "LASER" stands for Light Amplification by Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. This laser beam can cut, seal or vaporize skin tissue and blood vessels. The laser has the unique ability to produce one specific color (wavelength) of light which can be varied in its intensity and pulse duration. Ordinary light from non-laser sources is composed of many different colors and appears white. The wavelength and power output of a particular laser determines its medical application.
