Dual Wavelength Vs Multi-Wavelength Efficacy in Red Light Therapy

Why We Chose Multi-Wavelength Red Light Therapy (7 Wavelengths)

Here at RLT Home we offer our patent pending TotalSpectrum series of red light therapy devices with 7 wavelengths designed to provide whole-body wellness benefits. Let's discuss why our research led us to multi-wavelength devices and why we chose the wavelengths & strengths that we did choose.

Why We Chose Multi-Wavelength Red Light Therapy

When we at RLT Home first began researching and developing our red light therapy panels in 2021, dual wavelength panels utilizing 660nm and 850nm were the predominant devices on the market. However, we could not find concrete scientific evidence or reasons why limiting treatment to only those two wavelengths would provide optimal therapeutic results.

So we dug deeper, thoroughly reviewing over 1500 human trials and photobiology studies related to red and near-infrared light therapy. After comprehensive analysis spanning two years, we came to the conclusion in 2023 that utilizing seven wavelengths tuned to specific intensities allows red light devices to deliver superior performance and efficacy through a synergistic multi-band approach.

Let us explain the rationale behind this in greater depth:

The Basis for 660nm and 850nm Dual Therapy

It's true that a large number of studies have demonstrated benefits from 660nm and 850nm wavelengths. Our TotalSpectrum devices shine these two critical wavelengths with a higher intensity and LED density of around 44% each.

Studies show 660nm reduces inflammation and accelerates wound healing, while 850nm penetrates deeper into tissue and improves cellular functioning. But other wavelengths also have proven therapeutic effects.

The Benefits of Additional Wavelengths

Our TotalSpectrum devices add 5 more wavelengths to the core 660nm and 850nm:

• 💡 480nm - Targets surface-level skin concerns like acne by neutralizing bacteria and disrupting biofilms
• 💡 630nm - Increases collagen production and skin elasticity
• 💡 810nm - Stimulates the release of nitric oxide to promote circulation
• 💡 830nm - Penetrates deeper for musculoskeletal pain relief
• 💡 1064nm - Provides exceptional deep tissue penetration for chronic pain relief and improved blood flow

By analyzing the world's largest database of red light therapy studies, compiled by researcher Vladimir Heiskanen, we found:

• 🔬 Most human studies use multiple wavelengths in their protocols
• 🔬 Many studies don't even use 660 or 850nm, yet show positive results
• 🔬 Overall, multi-wavelength treatments demonstrate clear benefits

This suggests that while 660 and 850 are crucial, they work best together with other wavelengths in a synergistic way to enhance overall efficacy.

The RLT Home TotalSpectrum Advantage

With the TotalSpectrum series, here at RLT Home, we provide a diversified yet focused multi-wavelength treatment. We concentrate the highest LED density around 44% in the core 660nm and 850nm bands for maximum effectiveness. We add the other 5 wavelengths at lower densities to provide supporting therapeutic effects. And what that does is:

Synergistic effects

While studies show benefits from individual wavelengths, using multiple wavelengths simultaneously may have a synergistic effect, producing even greater benefits. The wavelengths can work together, triggering multiple biological pathways for enhanced results.

Targeting multiple tissue depths

Different wavelengths penetrate to different depths. Using a range targets more tissues and cells throughout the body. For example, 660nm targets superficial tissues, while 850nm reaches deeper layers.

Supporting mechanisms of action

Some wavelengths like 630nm and 810nm may not produce benefits on their own, but support the mechanisms of the primary therapeutic wavelengths. For example, 630nm improves cellular membranes which facilitates uptake of other wavelengths.

Targeting multiple indications

Different conditions may respond better to certain wavelengths. Multi-wavelength allows targeting multiple indications like skin health, inflammation, immune function, muscles/joints, circulation etc. simultaneously.

Individual differences

People have variables like skin type and thickness that impact optical penetration. Multi-wavelength improves the chances of generating a response by hitting the optimal bands.

Superior for whole-body use

Single wavelengths can be optimal for localized treatments, but systemic whole-body therapy demands a polychromatic approach to ensure uniform cell/tissue activation.

Complete coverage of depth

Approximate depth penetration by wavelength:

• 🩺 480nm: <1mm (epidermis, surface skin)
• 🩺 610-630nm: <5mm (skin, superficial tissue)
• 🩺 660nm: ~5mm (skin, shallow tissue)
• 🩺 810nm: ~10mm (dermis, hypodermis)
• 🩺 830-850nm: up to 30mm (subcutaneous tissue, muscle, joint, bone)
• 🩺 1064nm: up to 50mm+ (deep muscle, joints, organs)

The TotalSpectrum Series of red light therapy devices provides complete coverage of depths for systemic efficacy.

Dose-Response Relationship

The total delivered energy density (dose) affects therapeutic outcomes. There appears to be dose-dependency with increased fluences producing greater effects until plateauing. The TotalSpectrum allows higher total energy delivery (mJ/cm2) during a treatment session thanks to the expanded spectrum and intensity from the additional wavelengths.

Dual vs Multi-wavelength Efficacy in Red Light Therapy

The most common debate around red light therapy devices is whether two wavelengths provide superior benefits compared to a multi-wavelength approach. After extensive research, at RLT Home we believe multi-wavelength devices offer improved efficacy. While studies demonstrate positive outcomes from using 660nm and 850nm, other wavelengths also show confirmed therapeutic effects. By targeting multiple tissue depths simultaneously, a balanced multi-wavelength configuration can outperform single or dual narrowband devices.

Our Multi-Wavelength Devices vs Equal Intensity Multi-Wavelength Devices

However, our RLT Home TotalSpectrum series does not simply apply all wavelengths equally. We have engineered our multi-wavelength LED layout with research-backed advantages, including the highest LED density and intensity concentrated in the core 660nm and 850nm bands, then supplementing with supporting wavelengths at lower densities. This sets TotalSpectrum apart from equal intensity devices that lack the necessary power in the most effective wavelengths. The result is faster outcomes and enhanced user benefits.

Conclusion

In summary, by strategically incorporating multiple wavelengths at optimal intensities, RLT Home's TotalSpectrum series achieves superior irradiation coverage for unmatched systemic results. While many devices offer just 660 and 850nm, our research shows that a balanced combination of 7 wavelengths provides superior red light therapy results.
