Rødt lys terapi (RLT) typically works within the visible red and near-infrared (NIR) spekter av lys, measured in nanometer (nm).
Disse bølgelengdene trenger inn i huden på forskjellige dyp og utløser ulike biologiske effekter.
1️⃣ Red Light Range: 620–700 nm
- Common therapeutic wavelengths: 630 nm og 660 nm
- Inntrengningsdybde: Opp til 5–10 mm (reaches skin and shallow tissues)
- Best for:
- Hudforyngelse
- Collagen stimulation
- Reduserer fine linjer og rynker
- Healing superficial wounds or scars
- Reducing inflammation on the skin’s surface
🔬 Hvorfor det fungerer:
På dette området, light is absorbed by cytochrome c oxidase in your cells’ mitochondria, boosting ATP (energi) produksjon and accelerating cell repair.
2️⃣ Near-Infrared (NIR) Spekter: 800–900 nm
- Common therapeutic wavelengths: 810 nm, 830 nm, 850 nm, 880 nm
- Inntrengningsdybde: Opp til 30–40 mm (reaches muscles, ledd, og til og med bein)
- Best for:
- Muscle recovery and performance
- Joint and deep tissue pain relief
- Nerve regeneration
- Improving circulation and reducing inflammation
🔬 Hvorfor det fungerer:
NIR light penetrates deeper, improving blood flow and tissue oxygenation, supporting healing from the inside out.
3️⃣ Combined Red + NIR Therapy (Dual Spectrum)
Many advanced systems (like MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.
✅ 660 nm (rød): boosts skin health and surface healing
✅ 850 nm (nær-infrarød): targets deeper tissues and muscles
Sammen, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.
4️⃣ Summary Table
| Bølgelengde (nm) | Type lys | Inntrengningsdybde | Primære fordeler |
|---|---|---|---|
| 630 nm | Rød | Grunn | Skin healing, pigmentation repair |
| 660 nm | Rød | Medium | Collagen boost, anti-aldring |
| 810 nm | Nær-infrarød | Dyp | Nerve regeneration, sirkulasjon |
| 830 nm | Nær-infrarød | Dyp | Smertelindring, betennelse |
| 850 nm | Nær-infrarød | Very Deep | Muskelgjenoppretting, vevsreparasjon |
✅ In Short
De best wavelengths for red light therapy are 660 nm og 850 nm, often used together for maximum skin and body benefits.
