Red Light vs Near-Infrared Light

Red light therapy devices often advertise both red and near-infrared (NIR) wavelengths — but what’s the real difference? And do you actually need both?

In this guide, we break down how red and near-infrared light affect the body, how deep they go, and how to choose the right device for your goals.

What Is Red Light Therapy (660nm)?
Red light (around 630–670nm) is visible and primarily absorbed by the skin’s surface. It works best for:

-Improving skin tone and texture
-Reducing fine lines and wrinkles
-Stimulating collagen production
-Soothing inflammation and acne
**Red light is ideal for facial treatments, anti-aging, and skin repair.

 
What Is Near-Infrared Light (850nm)?
Near-infrared (NIR) light (typically 810–850nm) is invisible to the human eye but penetrates deeper into tissues, muscles, and joints.

It’s known for:

-Promoting muscle recovery and joint repair
-Improving circulation and oxygen delivery
-Reducing chronic pain and stiffness
-Supporting mitochondrial function at a cellular level
** NIR light is best for full-body wellness, soreness, and deeper healing.

Do You Need Both?
In short: yes — for most people.
Devices that combine both red and near-infrared light offer the widest range of benefits:

✅ Skin health + anti-aging
✅ Recovery + inflammation support
✅ Full-spectrum cellular health

Most high-quality panels today include both wavelengths for this reason.

Quick Buying Tip
When shopping for a red light therapy device:

Look for 660nm + 850nm specs listed clearly
Avoid products that only say “LED light” without wavelength details
Panels should emit both wavelengths simultaneously or in toggle mode
 
Red light and near-infrared light work best together.
If you want to improve both skin and deeper tissue recovery, go with a panel that offers both. Whether you’re focused on anti-aging, pain relief, or overall wellness, a combo device will give you the most return on your time and money.
