Red Light vs Infrared Light Therapy: Understanding the Key Differences

What is the Difference Between Infrared and Red Light Therapy?

The primary difference between infrared and red light therapy lies in their wavelength ranges and how deeply they penetrate body tissues. While both therapies use light energy that may support various wellness goals, red light therapy operates at 620-750 nanometers for surface-level applications, whereas infrared light therapy uses 700-1000 nanometer wavelengths that penetrate deeper into tissues. Understanding the difference between red light and infrared helps you make informed decisions about which therapy might complement your wellness routine.

How Red Light and Infrared Light Therapy Work

Both red infrared light therapies work through a process called photobiomodulation, where light energy is absorbed by cells. However, the difference between infrared and red light therapy becomes apparent in how and where this absorption occurs.

Red light therapy uses visible light that primarily interacts with surface-level skin cells and may support cellular energy production. The shorter wavelengths of red light are absorbed in the outer layers of skin tissue.

Infrared light therapy, particularly near-infrared, uses longer wavelengths that pass through the skin's surface to reach deeper tissues. When comparing infrared vs red light therapy, this deeper penetration is one of the most significant distinctions.

Red Light Therapy vs Infrared: Key Differences

Wavelengths and Penetration Depth

When examining red light vs infrared light, wavelength is the fundamental differentiator:

Red Light Therapy:

Wavelength range: 620-750 nanometers
Visible spectrum (you can see the red glow)
Penetration depth: Approximately 5-10mm into skin tissue
Primary absorption: Surface skin layers and superficial tissues

Infrared Light Therapy:

Wavelength range: 700-1000 nanometers (near-infrared)
Mostly invisible to the human eye
Penetration depth: Can reach 30-40mm into tissue
Primary absorption: Deeper muscles, joints, and tissues

The difference between red light and infrared penetration depth means each may be better suited for different applications such as wound healing.
