Red Light vs. Near-Infrared Light — What’s the Difference?
When exploring light-based devices, you may come across the terms red light and near-infrared light. These two types of light are often used together, but they differ in how they interact with the body.
Let’s take a simple look at how they compare.
What Is Red Light?
Wavelength Range: Approximately 600–700 nm
Penetration: Primarily interacts with the surface of the skin
Red light is commonly used in routines focused on skin appearance and general self-care. It is often included in devices designed for everyday use.
What Is Near-Infrared Light?
Wavelength Range: Approximately 800–1000 nm
Penetration: Reaches deeper beneath the surface compared to visible red light
Near-infrared light is often included in devices designed for broader coverage and comfort-focused routines.
Why Some Devices Use Both
Many modern devices combine red and near-infrared light to provide a more versatile experience.
Red light is typically used for surface-level applications
Near-infrared light reaches deeper layers
Using both allows users to include different types of light in a single routine.
Conclusion
Both red light and near-infrared light are used in light-based devices designed for everyday self-care and relaxation routines.
If you’re looking for flexibility, devices that include both types of light can offer a more adaptable experience for your routine.
