“Across all lenses, the assembled evidence is coherent: red and near-infrared LED and laser modalities both accelerate tissue repair without triggering bio-inhibition when dosed below the Arndt-Schulz threshold; choice of coherence can be tailored—LED for broad, superficial applications and laser for deep-tissue targets—while maintaining ANSI/JAMA Group 1 ocular safety limits; transcranial 630 nm interventions plausibly modulate formaldehyde dehydrogenase to support cognitive recovery; and adipocyte pore formation can release triglycerides only when paired with a caloric deficit to prevent reabsorption.”
