Low-level laser light therapy, also known as photobiomodulation, is a relatively new medical research sector shown to increase healing factors and cellular energy production; it has promising results in various conditions. It can be used for treatments from pain management and hair regrowing to skin rejuvenation.
How it Works
LLLT increases the amount of ATP or adenosine triphosphate produced in the cell’s mitochondrion. For this to work on the cell, it needs a specific wavelength of light at 635 nm. The increased energy allows the cell to promote healing and cell division, where the benefits are derived. In addition, it stimulates the release of nitric oxide, which increases blood flow and reduces inflammation in the area that is being treated.
Applications
Pain management is one of the most promising areas of photobiomodulation, with a robust amount of data to support it. Increasing healing factors and reducing inflammation can temporally relieve common sources of pain such as back pain, arthritis, and muscle pain from injury. Currently, it is used in sport medicine clinics to speed up the recovery of athletes and in pain management clinics.
Photobiomodulation is also well known in dermatology for treating certain types of hair loss, which has been backed by many small studies. The FDA recognizes this as an official treatment for pattern hair loss. The main way it works on the hair follicle is by making the cell go into the growing phase. The great thing about this treatment is that it can be done at home with devices that can be purchased without a prescription.
Dentistry
LLLT has shown promise in the field of dentistry to accelerate healing after procedures and to increase bone density. There are promising studies that show tooth restoration using stem cells to regrow the tooth pulp in combination with LLLT to promote regrowth.
Conclusion
Overall, low laser light therapy is a safe, non-invasive treatment option for a variety of conditions. While more research is needed to fully understand its potential, it is an exciting area of research that holds promise for the future of medicine.
