Soft laser therapy has been successfully used in medicine for over 50 years.
The following therapeutic effects support healing in nearly 100 medical conditions.
The pain-relieving effect of laser therapy is based on several biological processes:
Laser therapy causes the dilation of small arteries and lymphatic vessels. This increased vasodilation allows fluid buildup — which causes swelling (edema) — to be efficiently drained from the injured area.
The dilation of the lymphatic vessels also improves lymphatic circulation, which supports this essential healing process. This biological mechanism explains why bruising heals significantly faster as a result of laser therapy.
Soft lasers exert a biostimulatory (stimulating) effect on living tissue. This means that when cells and tissues are exposed to soft laser light, they regenerate more quickly — for example, wound healing is accelerated. Laser light increases cellular metabolism and stimulates the formation of new cells, tissues, and even new capillaries.
In summary: laser light stimulates the body’s natural self-healing ability.
Laser therapy also stimulates the production of fibroblasts, which are essential building blocks for collagen synthesis. Collagen is a vital protein necessary for the renewal of aging tissue and the healing of damaged tissue. Because of its collagen-boosting effect, laser therapy is particularly effective in treating open wounds and burn injuries.
Laser therapy reduces the formation of excessive scar tissue (fibrous connective tissue) following cuts, burns, and surgeries by improving blood supply to the injured area and promoting the efficient removal of waste products, thereby accelerating the healing process. Faster healing always results in less scar tissue formation.
Soft laser therapy significantly promotes the formation of new capillaries (tiny blood vessels) in damaged tissues. More capillaries mean more blood can be delivered to the affected areas, accelerating healing and regeneration processes, which leads to faster wound closure and reduced scarring.
Laser radiation also has a profound effect on certain blood cells. Laser light significantly increases the oxygen and nutrient-carrying capacity of red blood cells. This enables enhanced cellular energy production and metabolism, supporting regeneration and more efficient enzyme production. The effects are felt throughout the entire body, not only in the areas directly treated with laser light.
These two mechanisms explain why laser therapy is so effective in alleviating symptoms of nerve injuries such as sharp pain, numbness, tingling, and burning sensations.
The photons of laser light are directly absorbed by chromophores (pigment-carrying molecular enzymes within cells), which are found in most cells of the human body. The absorption of laser light activates certain enzymatic processes that trigger the production of ATP. ATP (adenosine triphosphate) is the only and most important form of energy that powers all chemical reactions in every cell of the body. The result of increased ATP production is faster and more efficient cellular function and regeneration, which is especially true for immune-specific cells. This enhanced efficiency helps the immune system combat unwanted microbes and pathogens.
