The Company, TrueDark, is located in Kent, Washington in the USA but the products are shipped worldwide.

What Are the Health Benefits of TrueLight products and How Do they Work?

TrueLight incorporates LED light therapy using a spectrum of wavelengths, including red, amber, infrared, blue, and yellow light. Each wavelength penetrates the body to varying depths, offering a range of health benefits:

  • Red Light: Enhances skin elasticity and appearance, aiding in skin rejuvenation.
  • Deep Red Light: Targets deeper layers of the skin, promoting further healing and restoration.
  • Yellow Light: Improves circulation and aids in scar reduction. It's also beneficial for sleep issues and restoring the circadian rhythm.
  • Near-Infrared Light: Focuses on deep tissue, increasing collagen density and reducing inflammation.

This technology works by emitting photons that stimulate the mitochondria within cells. This process boosts the production of ATP (adenosine triphosphate), the primary energy source for cells throughout the body, promoting optimal cell function. Exposure to light triggers physiological processes of therapeutic benefit.

The significance of ATP in health is highlighted in Todd A. Johnson, H. A. Jinnah, and Naoyuki Kamatani's research in “Frontiers in Pharmacology” where they discuss the implications of ATP deficiencies in disease development.

Each light wavelength offers specific benefits. Red light, for instance, is effective in wound healing and stimulating the production of collagen, elastin, and hyaluronic acid. These effects contribute to tightening the skin, enhancing its elasticity, smoothing wrinkles, and hydrating the skin and improving overall appearance.

A significant study demonstrating these benefits is “A Controlled Trial to Determine the Efficacy of Red and Near-Infrared Light Treatment in Patient Satisfaction, Reduction of Fine Lines, Wrinkles, Skin Roughness, and Intradermal Collagen Density Increase,” published in the journal Photomedicine and Laser Surgery in February 2014. This study provides scientific evidence supporting the effectiveness of red light therapy in improving skin health and appearance.

Meanwhile, blue and yellow light are known for their antibacterial properties and their role in reducing inflammation, making them effective in treating and preventing acne. Amber light, on the other hand, has been linked to improved sleep quality.

An example of a scientific study related to the benefits of yellow light in regulating sleep and circadian rhythms is Effects of light on human circadian rhythms, sleep and mood” published in the Medical Journal Somnologie in 2019 offers insights into the potential use of light therapy in treating sleep and mood disorders

This and other studies in recent years have explored how exposure to different wavelengths of light, including yellow, affects human circadian physiology, the sleep cycle, and mood, and the findings indicate that yellow light has a less disruptive impact on circadian rhythms compared to blue light and yellow light exposure resulted in lower melatonin suppression, suggesting its potential in sleep regulation.

Infrared light on the other hand penetrates the deepest, aiding in tissue healing, pain reduction, mood enhancement, brain health, and speeding up recovery after exercise among other benefits. Kelly A. Larkin-Kaiser, PhD, CAT(C), et al.'s study in the “Journal of Athletic Training” supports the use of infrared therapy in enhancing muscle function during rehabilitation post-injury.

An ever-growing body of scientific evidence underscores the benefits of red light therapy for various aspects of health and wellbeing, from promoting heart health to reducing pain and inflammation or enhancing exercise performance to promoting hair growth and more. The diversity in applications and availability of effective devices for home use have propelled products such as those by TrueLight to mainstream holistic treatment of choice.

Red light therapy is a type of therapy that uses red or near-infrared light to treat a variety of conditions. During a red light therapy session, a person is exposed to a specific wavelength of red or near-infrared light that is delivered through a light-emitting device. The light penetrates the skin and reaches the cells within the body with a range of therapeutic effects.

Understanding Red Light Therapy

Red light is a type of visible light, Its wavelength falls between approximately 630 and 700 nanometers (nm) on the electromagnetic spectrum. Red light is often used in light therapy treatments for the skin, as it has been shown to have the most beneficial effects on skin cells and collagen production.

Near-infrared (NIR) light, on the other hand, has a longer wavelength than visible red light and falls between approximately 700 and 1200 nm on the electromagnetic spectrum. NIR light is not visible to the human eye, but it can penetrate deeper into the skin and other tissues than visible light, making it useful for a variety of therapeutic applications ranging from wound healing to inflammation reduction or improved circulation, among other benefits.

Different Red Light Therapy devices usually deliver slightly different wavelength ranges that research has shown to be the most effective for the concern they are being recommended for.

Red Light Therapy (RLT)  strengthens the mitochondria, the cell’s powerhouse, where cell energy is created. Adenosine Triphosphate (ATP) is the critical energy-carrying molecule that is found in all living organisms. By optimizing the function of the mitochondria, more ATP is produced and with increased energy cells can function optimally.  

This scientific breakthrough resulted in scientists discovering Red Light Therapy’s ability to stimulate and speed up tissue repair and growth. Red Light Therapy is now widely used for maintaining a healthy complexion, speeding up muscle recovery, reducing inflammation, improving sleep, treating neurological conditions, balancing hormones, treating pain, and even losing weight.

Research has also indicated that Red Light Therapy can help to restore cellular balance and alleviate the negative impact of blue light exposure. The prevalence of blue light in our society has become a growing concern as many individuals spend prolonged periods of time looking at screens on a daily basis.

A Brief History of Red Light Therapy

The journey of Red Light Therapy (RLT) has been both fascinating and impactful, starting from its humble origins in the late 19th century. Dr. Niels Ryberg Finsen, the pioneer in light therapy, made a groundbreaking discovery in 1896 that light could be harnessed to treat Lupus Vulgaris, a form of tuberculosis affecting the skin. His work, which led to the tangible healing of skin lesions, was so revolutionary that he received the Nobel Prize in Physiology in 1903.

Fast forward to 1960, Theodore H. Maiman invented the first operational laser, fulfilling Albert Einstein's theories on the principles of lasers laid out in 1917. This invention opened new avenues for RLT, allowing more precise applications.

Understanding Red Light Therapy

NASA took an interest in Red Light Therapy in 1987, conducting experiments to examine its effects on plant growth in space missions. These studies hinted at RLT's potential to benefit not just human health but also broader ecological systems.

In the same vein, Endre Mester's work in 1967 set the stage for modern RLT applications.

His experimentation with low-level laser therapy on skin cancer effects demonstrated the technique's efficacy and led to FDA approval for wound healing in 2002.

The advent of LED technology in the 1990s was a game-changer, offering an efficient and cost-effective alternative to traditional light bulbs. This technological leap made light therapy more accessible to the general public, including its use in sports medicine where physical therapists reported quicker recovery times for sports-related injuries.

One of the most recent and exciting developments in RLT is its potential role in weight management. Studies indicate that Red Light Therapy can influence hormones like Leptin and Ghrelin, which play key roles in regulating appetite and metabolism. This makes RLT a promising avenue for non-invasive weight loss treatments.

As RLT continues to evolve, its applications keep expanding, crossing multiple disciplines from medicine to ecology. Researchers are continuously probing its potential, finding new ways to apply this age-old yet ever-advancing technology.
