Photobiomodulation (PBM) — How Does 660/850 nm Red Light Therapy Work?
Photobiomodulation (PBM), also known as red light therapy or LLLT (Low-Level Light Therapy), is one of the fastest-growing fields in physical medicine. It involves applying light of precisely selected wavelengths — primarily 660 nm (red) and 850 nm (near-infrared) — directly to body tissues. Professional photobiomodulation devices in Poland, such as Lumaflex® LED photobiomodulation panels, are available for both home and professional use.
The mechanism of action is precise and well-documented: light photons are absorbed by photoreceptors in cellular mitochondria, which can support increased cellular energy production (ATP), reduction of oxidative stress, and activation of repair processes.
PBM — The Photobiomodulation Pathway From Photon to Cell
Key to understanding photobiomodulation is the mitochondrion — the cellular organelle responsible for ATP production. When cells are damaged or overloaded, their mitochondria may produce less ATP — which can manifest as fatigue, slower regeneration, and discomfort.

The main photoreceptor is cytochrome c oxidase — an enzyme of complex IV of the mitochondrial respiratory chain. Research suggests that it absorbs photons from the red and near-infrared range, which can lead to increased ATP synthesis and activation of repair processes.
660 nm vs 850 nm — Differences Between PBM Wavelengths in Red Light Therapy
Not all red light works the same way. The effectiveness of photobiomodulation depends on the precise selection of wavelength — each penetrates tissues to a different depth and can activate different biological processes. Lumaflex® professional PBM devices combine both wavelengths in one LED photobiomodulation panel.
Penetrates the skin and superficial tissues up to approx. 5–10 mm. Studies suggest potential applications in skin regeneration, wound healing, and collagen production stimulation. Visible to the naked eye as an intense red glow.
Penetrates deeper — up to 30–40 mm, reaching muscles, joints, and bones. Invisible to the naked eye. Studies indicate potential for supporting post-exercise recovery and improving joint comfort.
PBM Red Light Therapy Dosage — Parameters Used in Research
One of the most frequently overlooked aspects of photobiomodulation is energy dose. Wavelength alone is not everything — how much energy (J/cm²) reaches the target tissue is equally important. Scientific studies have observed a biphasic dose response effect — in studies, too little power was less effective, too much could weaken the effects.
/ PBM Dose Parameters Used in Research
In scientific studies, doses of 20–100 mW/cm² were used. Lumaflex® devices are designed to deliver light directly to the skin — without loss due to distance. Traditional hanging panels lose up to 60% of energy due to the distance from the body.

Extensive scientific literature published in peer-reviewed journals documents a wide range of potential applications of photobiomodulation. Below are the most important areas that preliminary studies suggest as promising:
- Support in reducing musculoskeletal discomfort — studies suggest a potential reduction in perceived discomfort compared to placebo.
- Support for muscle regeneration after exercise — studies on athletes indicate a possible shortening of recovery time with regular PBM use; results may vary individually.
- Support for joint comfort — studies suggest potential benefits in improving joint comfort and mobility.
- Stimulation of collagen production — studies indicate potential applications in aesthetic dermatology and wound healing support.
- Support for neurological functions — promising results in preliminary studies; requires further clinical trials.
- Modulation of inflammatory response — preliminary studies suggest a possible effect on pro-inflammatory cytokines (TNF-α, IL-1β, IL-6); results require confirmation.
Safety of PBM Red Light Therapy
Photobiomodulation is distinguished by an exceptional safety profile. Unlike UV radiation, it does not cause DNA damage. It does not generate thermal effects that can damage tissues. Studies suggest that, when used correctly, it can be safe for a wide range of users. Caution is recommended in cases of pregnancy, active cancers in the irradiated area, and direct irradiation of the eyes. Always consult a doctor before starting therapy.

A standard session lasts from 10 to 20 minutes per body part. The duration depends on the device's power and the target energy dose (J/cm²). Lumaflex® devices are calibrated to deliver an optimal dose in 10–15 minutes.
Scientific studies used protocols of 5–7 sessions per week in the intensive phase and 2–3 sessions per week in the maintenance phase. Effects can be cumulative. Consult a specialist to choose an individual protocol.
Photobiomodulation is used in veterinary medicine — in horses, dogs, and cats. The mechanism of action is analogous to humans. Lumaflex Poland offers devices dedicated to both humans and animals. We recommend consulting a veterinarian before use.
Yes. Lumaflex Poland operates a rental service for professional photobiomodulation devices throughout Poland. This is an ideal solution for people who want to test the therapy before purchasing.
An infrared sauna works through a thermal effect — it heats the body. Photobiomodulation works at the cellular level through the absorption of photons by cytochrome c oxidase — without a thermal effect. These are two completely different technologies.
