Photobiomodulation Research
The science of light therapy. Peer-reviewed research on how specific wavelengths of red and near-infrared light affect cellular function, healing, and performance.
Research Synthesis
Key findings from 4,914 peer-reviewed studies on photobiomodulation therapy.
Mitochondrial ATP Production
Red and near-infrared light activates cytochrome c oxidase in mitochondria, increasing ATP production by 20-50% in treated cells.
Reduced Inflammation
PBM decreases pro-inflammatory cytokines (IL-1β, IL-6, TNF-α) and increases anti-inflammatory mediators.
Accelerated Wound Healing
345+ studies show PBM speeds wound closure, increases collagen synthesis, and improves tissue regeneration.
Neurological Benefits
243 brain studies demonstrate improved cognitive function, reduced neuroinflammation, and neuroprotection.
Bone Regeneration
PBM accelerates fracture healing, increases osteoblast activity, and improves bone mineral density.
Eye Health
104 studies on retinal protection, macular degeneration, and vision improvement through targeted light therapy.

The Biphasic Dose Response
PBM follows an Arndt-Schulz curve: too little light has no effect, optimal doses stimulate beneficial responses, and too much can inhibit or cause harm. This is why device specs should match research protocols.
