Laser therapy treatments seem simple on the surface, but what happens on the molecular level is a little more complex. Light is energy—and when it penetrates the skin and muscle tissue, the light particles interact with the cells making up that tissue. When the light particles come into contact with inflamed and/or damaged tissue, they help to increase cell metabolism. This results in more energy production and accelerates the healing process. The primary benefits of laser therapy include decreased inflammation and pain level, and increased blood circulation.
