Introduction
If you’re new to photobiomodulation, you may wonder: What kind of light is used for red light therapy? The answer is that red light therapy uses specific wavelengths of visible red light and near-infrared (NIR) light to support cellular function, skin health, and overall wellness.
Unlike UV light from the sun or tanning beds, red light therapy relies on low-level, non-ionizing light that is commonly used in wellness and recovery applications.
What Types of Light Are Used in Red Light Therapy?
Professional red light therapy devices typically use two categories of light:
Red Light (630nm–660nm)
Visible red light penetrates the skin surface and is commonly used for:
- Skin rejuvenation
- Collagen support
- Improving skin tone and texture
- Beauty and anti-aging treatments
The most popular wavelength in this range is 660nm, which is widely used in commercial red light therapy systems.
Near-Infrared Light (810nm–850nm)
Near-infrared light is invisible to the human eye but can penetrate deeper into tissues.
Potential applications include:
- Muscle recovery support
- Joint wellness
- Temporary inflammation management
- Sports recovery programs
Among NIR wavelengths, 850nm is one of the most commonly utilized.
Why LED Technology Is Commonly Used
Modern red light therapy systems typically use high-quality LEDs because they provide:
- Precise wavelength control
- Low heat output
- Long operational lifespan
- Consistent light delivery
The effectiveness of a red light therapy device depends not only on the LED technology itself but also on the wavelengths and treatment coverage it provides.
