Numerous trials on patients with an array of problems have linked red light therapy to cell growth and repair. In one study, for example, individuals who had suffered skin injuries saw increased collagen levels in their lower skin layers, when compared to a control group. Many of these patients achieved lasting recovery. While being effective in treating injuries and pain, it has also maintained a positive record for safety. Red light therapy has so far failed to show evidence of adverse side effects that accompany traditional solutions like prescription drugs. There has been no relationship established between red light therapy and certain setbacks that sometimes occur during recovery, such as inflammation and altered pain perception.
