Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The 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 that can be varied in its intensity and pulse duration. Ordinary light from non-laser sources is composed of many different colors and appears white. This broad spectrum of light can also be pulsed to a specific duration and varied in intensity as well as the exact range of wavelengths. This allows broad spectrum Intense Pulsed Light (IPL) the ability to specifically treat blood vessels and pigmentation.
