Red light (600-700nm) in the visible spectrum and near-infrared wavelengths (700-1200nm, NIR), which are invisible to the human eye, have been documented to stimulate healing, relieve pain, and reduce inflammation and bruising through Photo-Bio-Modulation (PBM) for nearly 50 years. Recently, the mechanisms of action and dosing have been elucidated, allowing us to prescribe light as a treatment modality.
Briefly, specific wavelengths of light are absorbed by chromophores (targets), triggering a cellular response that leads to desired outcomes. Certain wavelengths are strongly absorbed by cytochrome c oxidase in mitochondria, triggering the release of nitrous oxide and dramatically increasing ATP production (the energy source). This is the primary reason for reduced inflammation and increased healing. Circulating stem cell and exosome levels appear to increase for about 12 hours after illumination.
Targeted tissues exhibit a biphasic response to light that depends on wavelength, distance from the light source, pulsation, duration of exposure, and the illumination provided, such that an optimum energy density yields a maximal response. Too little net illumination does not produce the desired response, and too much may actually cause an inhibitory response.
Therefore, to provide a therapeutic dose of light energy knowledgeably, all variables must be accounted for, including the optimal wavelengths, the power and illumination delivered, and instructions for the patient on the required duration and distance to target to produce the desired responses.
Dr. Z has incorporated Red and NIR light PBM into many ARLV procedures to “prime” PRP, stem cells, and exosomes immediately before use, and to illuminate surgical and procedural patients during their office visits.
PBM has also been used to reduce insulin resistance and preserve hair follicles, and it may synergize with GLP1 use for weight loss. Patients can purchase these same clinical units for daily home use for wellness and as part of preparation for and recovery from surgeries.
After careful study, Aesthetic Revolution Las Vegas has chosen Redvive Health devices for our patients’ PBM needs. They are third-party tested for output, use wavelengths and penetration optimized for absorption by the intended targets without excessive heat production, offer a 60-day free trial, and include a two-year warranty at a competitive price. They are available only through physicians at this time. Other brands reviewed did not specify or provide independent comparisons of Power Output (Watts) or Energy Densities (J/cm2), absorption curves for the wavelengths provided, or illumination distances, nor did they provide peer-reviewed protocols for prescribing light as a treatment modality.
By understanding these variables, Dr. Z can prescribe safe, optimal dosing with these devices to enhance healing and reduce bruising and inflammation. He personally uses two of their systems daily and can attest to their effectiveness.
