How It Works
Understanding Red & Near-Infrared Light Therapy
Red and near-infrared light therapy—often discussed within the broader field of photobiomodulation—uses specific wavelengths of low-energy light delivered through LEDs or other light sources. Rather than relying on heat or ultraviolet radiation, the technology is based on the interaction between selected wavelengths of light and biological tissues.
The principle behind light therapy is that certain wavelengths can interact with cellular processes. Research has particularly explored the relationship between red and near-infrared light and mitochondria, the structures within cells involved in producing energy. The goal is not to force the body to do something unnatural, but to explore how targeted light exposure may support normal cellular processes.
01 — Targeted Light
The process begins when a device delivers a specific wavelength of light to the intended area. DrJoRed focuses on red and near-infrared wavelengths used in light therapy research, with 660nm red light and 850nm near-infrared light among the wavelengths referenced in the product catalog.
Different devices are designed for different applications and coverage areas. This allows light therapy to be used more purposefully depending on whether you are focusing on a smaller area, facial skincare, portability, or broader body coverage.
Key factors include:
- Wavelength
- Distance from the device
- Exposure time
- Irradiance
- Treatment area
- Consistency of use
02 — Cellular Interaction
Once the light reaches the targeted tissue, specific wavelengths can interact with biological structures within cells. One of the major areas of interest in photobiomodulation research is the mitochondria, which play an important role in cellular energy production.
The exact biological mechanisms are complex and continue to be studied, but researchers have investigated how red and near-infrared light may influence cellular signaling, energy-related processes, circulation, and tissue responses. This is one reason wavelength and the amount of light delivered are important when evaluating a light therapy device.
03 — Supporting the Body’s Natural Processes
The purpose of light therapy is to support biological processes rather than replace them. Research has explored applications involving muscle recovery, circulation, pain-related outcomes, skin health, and tissue response.
The DrJoRed approach is therefore centered on support, not exaggerated promises. Light therapy works best as part of a consistent routine alongside the fundamentals of wellness—such as appropriate exercise, nutrition, rest, skincare, and professional medical care when needed.
Why 660nm & 850nm?
Different wavelengths of light behave differently when they interact with biological tissue. DrJoRed's product range uses targeted red and near-infrared wavelengths, with 660nm and 850nm specifically referenced for its light therapy devices.
660nm Red Light
Red light is commonly associated with more surface-oriented applications and has been widely studied in areas such as skin health and cellular responses.
850nm Near-Infrared Light
Near-infrared light is less visible to the human eye and can penetrate further into tissue than visible red light. Research has explored its potential applications in areas such as recovery, circulation, and pain-related outcomes.
Why Consistency Matters
Light therapy is not designed around a single dramatic session. Like many wellness practices, consistency and appropriate use are important. Your experience can vary depending on the device, wavelength, treatment area, exposure, and individual factors.
Following the instructions provided with your specific DrJoRed device is essential. More light or longer exposure is not automatically better, and users should follow recommended usage and safety guidance.
Light Therapy, Made Understandable
The science behind photobiomodulation can become highly technical, but using the technology does not have to be complicated. DrJoRed's goal is to make the fundamentals easier to understand so you can make more informed decisions about whether and how light therapy fits into your routine.
