Why Red/NIR Wavelengths Matter
- Red and near-infrared (600–1100 nm) sit in an optical window that penetrates skin deeper than other wavelengths.
- Those wavelengths improve mitochondrial function and support broad systemic benefits by boosting ATP and cell signaling.
Multiple Cellular Mechanisms Explain Benefits
- Light likely acts via multiple mechanisms including cytochrome c oxidase, nitric oxide release, structured water, and microscopic temperature gradients.
- The therapy triggers a burst of ROS that signals healing, so dosing must balance beneficial signaling with overproduction risks.
Start Daily, Then Taper To Maintenance
- For acute issues use daily until you improve, then taper to a maintenance cadence every other day or a few times weekly.
- Avoid increasing dose when benefits wane; often reducing frequency or intensity restores responsiveness.
