Light Therapy consists of an LED device that emits red or infrared light that penetrates the skin to stimulate the energy production and other metabolic processes in targeted areas. The device provides relief of aches and pains. LED's are similar to lasers in that as they can emit the same light but differ in the way that the light energy is delivered. Lasers are focused-beam single-wavelength light emitters that can be intense enough to repair tissue. LED's promote natural self-healing and pain relief.
