Red Light Therapy Dosing
Red light therapy is not just about wavelength, it's about dose.
Red Light Therapy Dosing
Red light therapy is not just about wavelength, it's about dose.
The therapeutic effect of photobiomodulation depends on delivering the correct energy density (measured in J/cm²), at the appropriate wavelength, for the right duration and tissue depth.
Too little light may produce minimal results. Too much can blunt the biological response. Optimal dosing follows a biphasic dose response curve — meaning precision matters.
This page outlines evidence-based dosage ranges by tissue type and application.
Dosing Calculations
Skin | Aesthetics (4–8 J/cm²)
Hair | Scalp (~1.5–6 J/cm²)
Joints | Arthritis | Carpal Tunnel (~4–12 J/cm² per point)
Muscle Recovery | DOMS (~20–60 J/cm²)
Brain | Neurological (~9–13 J/cm² per site)
