When researching light therapy, you’ve probably seen the terms red light and near-infrared light. While they’re often used together, each wavelength works differently in the body. Let’s break down the differences and why both matter.
What Is Red Light Therapy?
- Wavelengths: 600–700nm
- Penetration Depth: Surface of the skin
- Benefits: Improves skin tone, reduces wrinkles, promotes collagen, helps with acne and scars.
- Best for people looking to improve skin health and appearance.
What Is Near-Infrared Light Therapy?
- Wavelengths: 800–1000nm
- Penetration Depth: Deeper into muscles, joints, and tissues
- Benefits: Relieves joint pain, supports muscle recovery, reduces inflammation, and boosts circulation.
- Best for people focusing on pain relief, recovery, or chronic conditions.
Why Most Devices Use Both
The combination of red and near-infrared light therapy provides full-body benefits:
- Red light works on the skin’s surface for rejuvenation.
- Near-infrared penetrates deeper for muscle, joint, and tissue health.
That’s why our red light therapy devices are designed with dual wavelengths — so you don’t have to choose one over the other.
Conclusion
If you want glowing skin, choose red light therapy. If you’re focused on pain relief and recovery, near-infrared is your best bet. But for the most complete benefits, go for a device that offers both wavelengths.
