Niels Finsen is considered to be the father of modern phototherapy, in 1903 he was awarded the Nobel Prize in Medicine and Psychology "in recognition of his contribution to the treatment of diseases, especially, lupus vulgaris with concentrated light radiation, whereby he has opened a new avenue for medical science."
Since then a vast array of treatments using controlled light have been developed together with the creation of special devices for research and treatment.
More than 30 years ago NASA began to use LED tech for growing plants on the International Space Station, later on, NASA scientists have found a new use for it in the medical field.
In 2011 specialists from Birmingham Hospital and the Children's Hospital of Alabama published results of a two-year clinical trial of using 670 nanometers of light technology for 80 cancer patients undergoing bone marrow or stem cell transplants and who experienced improvements the painful side effects of chemotherapy and radiation.
Results from a 2014 study published in “Photomedicine and Laser Surgery” demonstrated both efficacy and safety for red light therapy in promoting rejuvenation of skin and stimulation of collagen production. Subjects treated experienced significantly improved skin complexion, improved skin tone, improved texture/feeling, reduced skin roughness, reduced signs of wrinkles and fine lines, and increased collagen density. Patients with rosacea and redness have also found relief.
Red light therapy has been proven to provide relief from chronic and acute pain including muscle and joint pain, arthritis, high blood pressure, tissue and nerve damage, and can decrease injury healing time. Discovered by NASA for this purpose, red light therapy is now used by professional athletes to promote healing with powerful results.
One of the most recent applications of PBM offers an innovative and non-invasive therapeutic approach to a host of challenging sight-threatening retinal conditions. 670 nm red light* has been shown to be a powerful neuroprotectant, against light induced damage and toxins. Treatment with 670 nm red light improves retinal healing and modulates expression of genes involved with inflammation, oxidative metabolism, and apoptosis.
