Plain-English Summary
PBM dose-response review in Photobiomodulation researchers and clinicians evaluating dose-response behavior. Photobiomodulation can follow a biphasic response where too little or too much light may fail.

How the study framework works ->Key Findings
- Photobiomodulation can follow a biphasic response where too little or too much light may fail.
- This is central to consumer-device interpretation.
Limitations
- Dose-response concepts do not specify the best consumer protocol for every device.
- Different tissues and wavelengths may behave differently.
Why It Matters
Dose window, stimulation versus inhibition, and overexposure boundary.
Viral Vitalism Verdict
Useful evidence, bounded by design: Dose-response concepts do not specify the best consumer protocol for every device.

Red Light Therapy: Mitochondrial Medicine or Expensive Lamp Culture?
Red and near-infrared light claims range from skin and pain to hair growth, testosterone, thyroid, fat loss, and brain performance. The evidence is not one category. Dose, wavelength, distance, tissue depth, and outcome decide whether the claim is medicine, beauty tech, rehab tool, or expensive lamp culture.
