Laser treatments enhance blood circulation and lymphatic drainage; release oxygen and nutrients from the bloodstream into the tissues and improve cellular metabolic activity to produce more cellular energy. With more energy available, damaged cells can repair and regenerate more quickly, and with better quality. 

Photons of laser light penetrate deeply into tissue and accelerate cellular reproduction and growth. The laser light increases the energy available to the cell so that the cell can take on nutrients faster and get rid of waste products. As a result, the cells of tendons, ligaments, bone, nerves, and muscles are repaired faster. 

Laser therapy stimulates fibroblast development (fibroblasts are the building blocks of collagen, which is predominant in wound healing) in damaged tissue. Collagen is the essential protein required to replace old tissue or to repair tissue injuries. As a result, laser therapy is effective on open wounds, scars, and burns. 

Laser therapy reduces the formation of scar tissue following damage from cuts, scratches, burns or surgery by inducing production of more normal type-1 collagen. Scar tissue is the primary source of chronic pain. Laser treatments should be given as soon as possible after any acute injury to promote type-1 collagen production and parallel alignment of the collagen fibers. 

Laser treatments modulate inflammation by causing vasodilation and activating the lymphatic drainage system. As a result, there is a reduction in swelling caused by bruising or inflammation. Try not to say that laser treatments are "anti-inflammatory", as they do not suppress inflammation as non-steroidal anti-inflammatory drugs (NSAIDs) do. Rather, Class IV laser therapy treatments help the body progress through the stages of inflammation more efficiently. 

Laser therapy can reduce the firing of the C-pain fibers that transmit signals of "pain" from the cells to the brain. Increased blood circulation flushes away tissue irritants called "kinins". Pain modulating chemicals such as endorphins and enkephalins are released from the brain and adrenal gland. Increased cell membrane permeability encourages normal concentrations of ions across the cell membrane, and the resting potential of pain fibers is returned to -70 millivolts. 

Laser therapy will significantly increase the formation of new capillaries in damaged tissue that speeds up the heling process, closes wounds quickly and reduces scar tissue. Additional benefits include acceleration of angiogenesis, which causes temporary vasodilation, an increase inn the diameter of blood vessels. More blood flow equals faster healing and less pain. 

Slow recovery of nerve functions in damaged tissue can result in numbness and impaired limbs. Laser therapy will speed up the process of nerve cell reconnection and increase the amplitude of action potentials to optimize muscle action. 

Laser therapy can both increase the local immune system response as well as have a positive effect on the whole-body immune response. Increased circulation and enhanced cellular energy production will enhance the activity of immune system cells, helping to reduce and fight infection. 

Laser therapy reduces muscle trigger points and stimulates acupuncture points on a non-invasive basis providing musculoskeletal pain relief.
