Red light therapy and LED therapy are often confused. Here's the actual difference.
What Is Red Light Therapy?
Red light therapy uses specific wavelengths of light (typically 633-660 nm red, 850 nm near-infrared) to penetrate skin and trigger cellular repair. The light is absorbed by mitochondria, boosting cellular energy.
It's called "PBM" (photobiomodulation) in scientific literature.
What Is LED Therapy?
LED therapy is a broader category. LEDs (light-emitting diodes) can produce different colors:
- Red (633-660 nm) - anti-aging, collagen
- Blue (415 nm) - acne, bacteria
- Yellow (590 nm) - redness
- Near-infrared (850 nm) - deeper healing
- Amber (570-590 nm) - pigmentation
Red light therapy IS a form of LED therapy - specifically using red + near-infrared wavelengths.
Key Differences
| Property | Red Light | General LED |
|---|---|---|
| Wavelength | Specific | Any color |
| Research | Strong | Mixed |
| Specific benefits | Documented | Varies |
What to Look For
Look for:
- 633 nm red + 850 nm near-infrared
- FDA-cleared device
- Sufficient number of LEDs
- Quality brands
