Red light therapy (RLT), an innovative therapeutic technique, is garnering significant interest in the healthcare community for its varied applications in treating health conditions. Originating from NASA’s space research, where it was used for plant growth and wound healing in astronauts, RLT employs low-wavelength red light, believed to be beneficial at the cellular level. This therapy’s growing popularity is supported by numerous studies, including those published by the National Institutes of Health (NIH), although comprehensive research is still ongoing to fully validate its wide range of benefits.

Various devices are used to deliver RLT, each designed for specific applications and conveniences. These range from hand-held units for targeted areas to larger panels for broader coverage. Red light therapy beds, which encompass the entire body, are becoming increasingly popular for their efficiency in delivering the therapy over a large area. The choice of device typically depends on the specific health condition being addressed, the area of the body targeted, and the convenience of use.


While most companies create simple systems that target a single chromophore without frequency augmentation, ARRC LED goes Beyond Red Light Therapy.  

ARRC LED utilizes 6 wavelengths of light rather than traditional 2 – 4.  ARRC LED targets 3 unique chromophores for three unique sets of benefits while traditional PBMt targets only 1.  ARRC LED and ARRC BIOTECH are Frequency Medicine Devices.   This allows our systems to utilize the power of frequency augmentation to shape how the light is delivered and what it influences.

Understanding Traditional Red Light Therapy

At the core of RLT involves the absorption of red/near-infrared light energy by mitochondria within the cells. This absorption enhances mitochondrial ATP (adenosine triphosphate) production, stimulates cell signaling, and aids in growth factor synthesis while attenuating oxidative stress.Photobiomodulation, the process by which RLT influences cell function, has been a subject of extensive research, particularly regarding its anti-inflammatory effects. Studies have shown that Red Light Therapy can activate transcription factors leading to improved cell survival, increased cell proliferation and migration, and new protein synthesis. A significant aspect of these effects is the reduction of inflammation, which is crucial for disorders involving the joints, lungs, and brain​​​​.

Skin Health and Anti-Aging

Red light therapy (RLT) has shown considerable promise in the field of dermatology, particularly in addressing signs of aging such as wrinkles, redness, acne, and scars. Its effectiveness in treating skin conditions is grounded in its ability to stimulate collagen production, a key protein responsible for skin elasticity and firmness. The increase in collagen not only helps in reducing the appearance of fine lines and wrinkles but also enhances the overall texture and health of the skin.

Red Light Therapy is also known for its role in improving blood circulation to the skin, which is crucial for delivering essential nutrients and oxygen, thus promoting healthier skin. This enhanced circulation also contributes to a more even skin tone and aids in reducing the appearance of redness and irritation.

Another benefit of Red Light Therapy being researched is its anti-inflammatory properties. By reducing inflammation at a cellular level, RLT can be particularly effective in treating conditions like acne and rosacea, which are characterized by inflammation and redness. Furthermore, its ability to accelerate the healing process makes it a useful tool in reducing the appearance of scars and other skin imperfections.

Although Red Light Therapy (RLT) is becoming increasingly popular for its skin care and anti-aging benefits, the exploration of its long-term safety and efficacy continues. The encouraging results seen thus far point to the need for more expansive clinical trials and studies to further unveil the full potential and define the boundaries of this innovative therapy in dermatology.

Pain Management and Muscle Recovery

Red light therapy (RLT) has gained significant recognition for its potential in pain management and muscle recovery. It is believed to potentially speed up the response of muscle cells and facilitate recovery, which could be particularly beneficial for athletes and fitness enthusiasts. RLT is being explored for its role in aiding muscle tear healing and reducing lactate levels, a major factor in muscle fatigue, thereby potentially enhancing post-workout recovery.

The biostimulatory effects of Red Light Therapy (RLT) on muscle tissue, which are thought to include increased blood flow and a potential reduction in inflammation, may contribute to faster recovery from exercise-induced muscle strains and injuries. These aspects of RLT are of particular interest in sports medicine for their potential to aid in quick recovery, which is crucial for maintaining peak athletic performance. Furthermore, the role of RLT in pain management, especially for chronic conditions like arthritis and back pain, is currently being supported by ongoing clinical research. RLT is being explored as a non-pharmacological alternative for pain management, potentially helping to reduce pain and inflammation.

Mental Health and Sleep Quality

Emerging research, including preliminary studies, highlights the potential role of Red Light Therapy (RLT) in the treatment of mental health disorders. Researchers suggets that RLT possess antidepressant properties, potentially improving mood, mental clarity, and overall well-being. This is particularly relevant for conditions such as depression, anxiety, and bipolar disorder.

A systematic review titled “Transcranial and systemic photobiomodulation for major depressive disorder” delves into the efficacy, tolerability, and biological mechanisms of RLT in treating major depressive disorder (MDD). The review suggests that RLT, including non-retinal PBM (Photobiomodulation) with red and near-infrared light, shows significant antidepressant effects and good tolerability in clinical studies. This implies a promising future for RLT as a novel treatment for MDD, though more rigorous clinical studies are required to determine optimal stimulation parameters and the overall safety profile of this treatment.

Further, a meta-analysis titled “The efficacy of light therapy in the treatment of mood disorders” provides an assessment of the efficacy of light therapy in treating mood disorders. The study concluded that bright light treatment is efficacious for seasonal affective disorder and nonseasonal depression, with effect sizes comparable to those in most antidepressant pharmacotherapy trials. This underscores the potential of light therapy, including RLT, as a viable treatment option for mood disorders.

Another meta-analysis, “Light therapy in non-seasonal depression,” emphasizes the effectiveness of light therapy in reducing depressive symptoms, suggesting its use as a clinical therapy for non-seasonal depression. While the evidence indicates a mild to moderate treatment effect, the study calls for more well-designed research to confirm the efficiency of light therapy in treating non-seasonal depression.

Red light therapy, as an evolving field, demonstrates promising potential across a variety of health areas. Early research, contributed by numerous scientists and institutions worldwide, has shown encouraging results, particularly in the realms of skin health, pain management, muscle recovery, and mental well-being. Yet, to fully grasp its effectiveness and ascertain long-term safety, more comprehensive and in-depth studies are necessary. As with any emerging treatment, consulting healthcare professionals is essential before considering RLT as a part of any health regimen.
