Red Light Therapy 101: How Photobiomodulation Heals Skin and Joints

At Via Nova Health, Dr. Jeffrey E. Matz, DC, MS, helps patients understand how red light therapy, also known as photobiomodulation, uses targeted wavelengths of red and near-infrared light to support cellular energy and tissue function. By influencing mitochondrial activity and ATP production, this noninvasive approach may help support skin health, collagen production, muscle recovery, joint comfort, and the body’s natural repair processes. Our team considers individual wellness goals when determining how red or near-infrared wavelengths may be incorporated into a personalized care plan. Treatment recommendations may vary depending on the targeted area, desired outcomes, and overall health considerations. For more information, please contact us or book an appointment online. We are conveniently located at 1672 Overview Dr, Rock Hill, SC 29730.

Red light therapy panels have transitioned from high-end longevity clinics directly into home bedrooms. But to the uninitiated, sitting in front of a glowing red box can look a bit like science fiction.

Clinically referred to as photobiomodulation, this alternative therapy isn’t a gimmick; it is a scientifically verified method of using specific wavelengths of light to fuel cellular energy, reduce pain, and accelerate tissue repair.

Recharging Your Cellular Batteries

To understand how red light works, we have to look inside your mitochondria, the powerhouses of your cells. Your mitochondria use an enzyme called cytochrome c oxidase to process oxygen and create ATP (Adenosine Triphosphate), the universal energy currency your body uses to heal and function.

When your cells are stressed, injured, or aging, a molecule called nitric oxide binds to this enzyme, effectively blocking oxygen from entering the cell and stalling energy production.

As illustrated, when you expose your skin to specific wavelengths of red light (660nm) and near-infrared light (850nm), the light photons displace that restrictive nitric oxide. This unlocks the cellular machinery, allowing your mitochondria to rapidly process oxygen and supercharge ATP production.

Skin vs. Joints: Choosing the Right Wave

At-home panels typically offer two distinct settings, each targeting different depths of tissue:

• Red Light (630–660nm): This wavelength has a shorter reach, making it ideal for surface-level application. It stimulates collagen synthesis, fades hyperpigmentation, reduces systemic acne inflammation, and accelerates superficial wound healing.
• Near-Infrared Light (810–850nm): This light is invisible to the human eye and travels deep into the physical body, penetrating fat layers, muscles, and even bone. This deep reach makes it highly effective for soothing joint pain, relaxing deep muscle tissue, speeding up athletic recovery, and calming chronic systemic inflammation.
