Laser is a form that applies low power to the surface or orifices of the body. The laser improves tissue repair such as skin wounds, nerves, bone, tendon, muscle, reduces pain and inflammation wherever the laser is applied. It typically take 4-15 minutes.  Laser works predominately on a protein in mitochondria to increase ATP and reduce oxidative stress. A cascade of mitochondrial and intracellular downstream effects lead to improved tissue repair and reduced inflammation. The power density is necessary for analgesia and deep tissue targets, low power density is necessary to promote healing and reduce inflammation in superficial wounds, tendons and joints.
