What is Cold Laser Therapy and How Does it Work?
LASER stands for Light Amplification via Stimulated Emission of Radiation. Laser light consists of an energy source, laser material which absorbs energy and emits it as light. And finally, there is a cavity which channels the light into a beam. Low Level Laser (or Cold Laser) can penetrate skin and tissue without heating it. Laser light wavelength is measured in nanometers (nm) and the output, or strength of the laser light, is measured in milliwatts (mW). Although both LED a
