Terapi lampu merah (RLT) typically works within the visible red and near-infrared (NIR) spectrum of light, diukur dalam 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 dan 660 nm
- Penetration depth: Up to 5–10 mm (reaches skin and shallow tissues)
- Terbaik untuk:
- Peremajaan kulit
- Collagen stimulation
- Mengurangkan garis halus dan kedutan
- Healing superficial wounds or scars
- Reducing inflammation on the skin’s surface
🔬 Why it works:
At this range, light is absorbed by cytochrome c oxidase in your cells’ mitochondria, boosting ATP (tenaga) pengeluaran and accelerating cell repair.
2️⃣ Near-Infrared (NIR) Range: 800–900 nm
- Common therapeutic wavelengths: 810 nm, 830 nm, 850 nm, 880 nm
- Penetration depth: Up to 30–40 mm (reaches muscles, sendi, dan juga tulang)
- Terbaik untuk:
- Muscle recovery and performance
- Joint and deep tissue pain relief
- Nerve regeneration
- Improving circulation and reducing inflammation
🔬 Why it works:
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 (suka MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.
✅ 660 nm (merah): boosts skin health and surface healing
✅ 850 nm (inframerah dekat): targets deeper tissues and muscles
bersama-sama, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.
4️⃣ Summary Table
| Panjang gelombang (nm) | Jenis Cahaya | Kedalaman Penembusan | Faedah Utama |
|---|---|---|---|
| 630 nm | merah | Shallow | Skin healing, pigmentation repair |
| 660 nm | merah | Medium | Collagen boost, anti penuaan |
| 810 nm | Inframerah Dekat | Dalam | Nerve regeneration, peredaran |
| 830 nm | Inframerah Dekat | Dalam | melegakan kesakitan, keradangan |
| 850 nm | Inframerah Dekat | Very Deep | Pemulihan otot, pembaikan tisu |
✅ In Short
The best wavelengths for red light therapy are 660 nm dan 850 nm, often used together for maximum skin and body benefits.
