赤色光療法 (RLT) typically works within the visible red and near-infrared (nir) spectrum of light, measured in ナノメートル (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 そして 660 nm
- Penetration depth: まで 5–10mm (reaches skin and shallow tissues)
- こんな方に最適:
- 肌の若返り
- 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 シトクロムCオキシダーゼ in your cells’ mitochondria, ブースト ATP (エネルギー) 生産 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: まで 30–40 mm (reaches muscles, 関節, そして骨さえも)
- こんな方に最適:
- 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 (のように MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.
✅ 660 nm (赤): boosts skin health and surface healing
✅ 850 nm (近赤外): targets deeper tissues and muscles
一緒に, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.
4️⃣ Summary Table
| 波長 (nm) | Type of Light | 浸透深さ | 主なメリット |
|---|---|---|---|
| 630 nm | 赤 | 浅い | Skin healing, pigmentation repair |
| 660 nm | 赤 | 中くらい | Collagen boost, アンチエイジング |
| 810 nm | 近赤外線 | 深い | Nerve regeneration, 循環 |
| 830 nm | 近赤外線 | 深い | 痛みの軽減, 炎症 |
| 850 nm | 近赤外線 | Very Deep | 筋肉の回復, 組織修復 |
✅ In Short
The 最高の波長 for red light therapy are 660 nm そして 850 nm, often used together for maximum skin and body benefits.
