Rödljusterapi (RLT) typically works within the visible red and near-infrared (NIR) spectrum of light, mätt i nanometer (nm).
These wavelengths penetrate the skin at different depths and trigger various biological effects.
1️⃣ Red Light Range: 620–700 nm
- Common therapeutic wavelengths: 630 nm och 660 nm
- Inträngningsdjup: Fram till 5–10 mm (reaches skin and shallow tissues)
- Bäst för:
- Hudföryngring
- Collagen stimulation
- Reducing fine lines and wrinkles
- Healing superficial wounds or scars
- Reducing inflammation on the skin’s surface
🔬 Why it works:
At this range, light is absorbed by cytokrom c-oxidas in your cells’ mitochondria, boosting ATP (energi) produktion and accelerating cell repair.
2️⃣ Near-Infrared (NIR) Range: 800–900 nm
- Common therapeutic wavelengths: 810 nm, 830 nm, 850 nm, 880 nm
- Inträngningsdjup: Fram till 30–40 mm (reaches muscles, leder, och även ben)
- Bäst för:
- Muscle recovery and performance
- Joint and deep tissue pain relief
- Nerve regeneration
- Improving circulation and reducing inflammation
🔬 Why it works:
NIR-ljus tränger djupare in, improving blood flow and tissue oxygenation, supporting healing from the inside out.
3️⃣ Combined Red + NIR Therapy (Dual Spectrum)
Many advanced systems (som MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.
✅ 660 nm (röd): boosts skin health and surface healing
✅ 850 nm (nära-infrarött): targets deeper tissues and muscles
Tillsammans, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.
4️⃣ Summary Table
| Våglängd (nm) | Typ av ljus | Inträngningsdjup | Primära förmåner |
|---|---|---|---|
| 630 nm | Röd | Grund | Skin healing, pigmentation repair |
| 660 nm | Röd | Medium | Collagen boost, anti-aging |
| 810 nm | Nära-infraröd | Djup | Nerve regeneration, omlopp |
| 830 nm | Nära-infraröd | Djup | Smärtlindring, inflammation |
| 850 nm | Nära-infraröd | Very Deep | Återhämtning av muskler, vävnadsreparation |
✅ In Short
De best wavelengths for red light therapy are 660 nm och 850 nm, often used together for maximum skin and body benefits.
