How does it work?
At the highest end of the visible light spectrum is red light, which goes from a
little over 600nm to approximately 700nm.
Above the visible light spectrum is near infrared (NIR) from about 700nm to a little over 1100nm. It’s specifically these red and near-infrared wavelengths that have amazing effects on our bodies. The longer the wavelength, the deeper the penetration, thus delivering energy to cells, stimulating healing and relieving
pain. Most research showing benefits of red light and near-infrared light have used wavelengths in the ranges of 620-680nm and 800-880nm. There have now been literally thousands of studies done in both animals and humans.
Overall, red and near infrared light has been repeatedly shown to have positive effects on cell function in animal and human studies and aid in improving a wide range of conditions.
What exactly is Red Light Therapy?
Red Light Therapy (RLT), also known as photobiomodulation, uses specific wavelengths of light to penetrate the skin. This light stimulates the mitochondria in your cells, increasing the production of ATP (energy). More cellular energy means faster healing, less inflammation, and rejuvenated skin. Red Light Therapy is a process of emitting light wavelengths through the skin to stimulate your bodies natural healing and regeneration process.
When delivered within the optimal wavelengths and energy levels, red and near infrared light protect your body’s cells from nitric oxide damage, which can otherwise stop the cell’s production of ATP when you’re stressed or ill. Red light photons allow your cells to continue utilizing oxygen effectively by minimizing the absorption of nitric oxide. Only red-light therapy can reach
all the way into cell’s mitochondria to stimulate healing and regeneration to help improve your appearance, performance and your overall well-being.
What is the difference between Red and Near-Infrared (NIR)?
Red Light (660nm) is visible and is absorbed by the surface of the skin (great for wrinkles and acne).
Near-Infrared (850nm) is invisible to the human eye and penetrates deep into muscles, joints, and bones.
How long does it take for red light therapy to work?
It is not an immediate miracle transformation that will occur overnight, but it will provide you with ongoing improvements that you will begin to see in anywhere from 24 hours to 2 months, depending on the condition, its severity, and how regularly the light is used. For most conditions, daily use for at least two weeks is recommended, followed by a once- or twice- weekly maintenance regimen.
Do I need to continue to use the light as much when I start seeing results?
Yes. Just because you're seeing results, it doesn't mean that your skin cells are finished doing their jobs. It's just that the
results of their efforts are starting to become something you can see and/or feel. Keep up the treatments until you reach your goal level of results. Then you can start a weekly maintenance schedule.
What is the difference between a red light panel and other therapy devices?
Red light panels typically offer larger treatment coverage and higher power output compared to handheld devices, making them ideal for muscle and joint recovery.
Is there scientific proof that red light speeds tissue repair?
Research shows positive biological effects on collagen production, inflammation modulation, and cellular ATP levels — all relevant to healing — but results vary by protocol and device.
Should red light therapy be used with other treatments?
Yes— RLT can complement dermatological treatments like microneedling, topical retinoids, or professional laser therapy, often enhancing outcomes.
What is the best wavelength for deep tissue healing?
Near-infrared wavelengths around 810–850 nm penetrates most deeply and are
most commonly used for muscle and joint recovery.
Can I combine red light therapy with massage or heat therapy for my clients?
Absolutely. Combining therapies enhances circulation and boosts recovery results.
