The "nm" stands for nanometers, which is a unit of measurement used to describe the wavelength of light, specifically in red and near-infrared light therapy. In short:
-
Lower nm (red light) = surface-level benefits (skin, inflammation)
-
Higher nm (NIR/IR) = deeper penetration (muscle, joint, brain)
Here’s a simple breakdown:
|
Wavelength (nm) |
Light Type |
Main Benefits |
|
630–670nm |
Red Light |
Skin health, collagen boost, wrinkle reduction, acne |
|
810nm |
Near-Infrared (NIR) |
Brain function, cognitive support, neurological recovery |
|
830nm |
Near-Infrared (NIR) |
Deeper tissue healing, faster recovery, reduced inflammation |
|
850nm |
Near-Infrared (NIR) |
Muscle recovery, joint pain relief, anti-inflammatory |
|
1060nm |
Deep Infrared |
Fat reduction, deep tissue stimulation (often thermal) |
