Unlike high-power medical lasers, which are widely used to cut and burn tissue, low-level lasers (LLLs), or cold lasers, penetrate the surface of the skin with little or no heating effect and no potential tissue damage. The energy is directed deep into the treatment area to stimulate the body’s cells, which convert the light energy into chemical energy to promote natural healing. In most cases, cold laser therapy is considered an alternative therapy like acupuncture and physical therapy.
