Wavelength
Red and near-infrared wavelengths are studied separately and in combination.
Science & evidence library
Read the evidence. Know its limits.
Red and near-infrared light have been studied across many devices, doses, and use cases. This library explains selected peer-reviewed research without presenting third-party results as proof for an ALPHALUX product.

A clear starting point
What the research can—and cannot—tell us.
Dose
Irradiance and time work together; a larger number is not automatically better.
Protocol
Distance, frequency, treatment area, and study duration affect interpretation.
Transferability
Results from one study device cannot be assumed for a different product.

Facial rejuvenation frequency: randomized, sham-controlled clinical trial
This 2025 trial studied a 660 nm LED mask in 95 women. Image analysis found changes in selected wrinkle measurements, while the clinical wrinkle scale found no significant difference between groups. The mixed endpoints matter when interpreting the result.

633 nm and 830 nm LED phototherapy: split-face controlled study
This 2007 study enrolled 76 people and compared three light settings with sham treatment. It reported changes in measured wrinkles, elasticity, and tissue markers after the study protocol. It did not test an ALPHALUX device.

Photobiomodulation with an exercise program in knee osteoarthritis
In this placebo-controlled trial of 62 women, active photobiomodulation groups reported lower pain scores than placebo. Exercise improved several physical-capacity measures, and adding photobiomodulation did not provide an extra effect on those measures.

810 nm photobiomodulation before exercise: comparing power outputs
This randomized human study compared different power outputs while examining muscle performance and post-exercise recovery. It is useful evidence that device settings and delivered dose cannot be reduced to a single ‘more is better’ number.

Biphasic dose response in low-level light therapy
This review explains the biphasic dose-response concept: an insufficient dose may have little effect, while a dose beyond the useful range may also reduce the response. Study parameters and context remain essential.

Why dosing photobiomodulation is challenging
This review discusses how wavelength, irradiance, exposure time, tissue, distance, and treatment schedule interact. Findings from one protocol should not automatically be transferred to another device or use case.

Science FAQ
What is photobiomodulation?
Photobiomodulation, often shortened to PBM, is the study and use of non-ionizing visible or near-infrared light to influence biological processes. Outcomes depend on wavelength, dose, tissue, protocol, and the population studied.
Does a published red-light study prove an ALPHALUX product has the same result?
No. A third-party study supports understanding of its specific device and protocol. It is not product-specific clinical proof for ALPHALUX unless the ALPHALUX product itself was tested in that study.
Is higher irradiance always better?
No. Reviews describe a biphasic dose response, and total delivered dose depends on more than irradiance alone. Wavelength, distance, exposure time, treatment area, and schedule all matter.
Is this page medical advice?
No. This library is educational and does not diagnose, treat, cure, or prevent disease. Ask a qualified healthcare professional about personal health conditions, medications, or photosensitivity.
