Low-level laser (light) therapy (LLLT) is a fast-growing technology used to treat a multitude of conditions that require stimulation of healing, relief of pain and inflammation, and restoration of function. Although the skin is the organ that is naturally exposed to light more than any other organ, it still responds well to red and near-infrared wavelengths.

The photons are absorbed by mitochondrial chromophores in skin cells. Consequently electron transport, adenosine triphosphate (ATP) nitric oxide release, blood flow, reactive oxygen species increase and diverse signaling pathways get activated vanitygen. Stem cells can be activated allowing increased tissue repair and healing of musculoskeletal injuries including tendinitis, bursitis, muscle spasms, etc. due to different causes including sports injuries, auto accident injuries, etc.
