빨간불 치료 (RLT) typically works within the visible red and near-infrared (근적외선) spectrum of light, measured in 나노미터 (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 그리고 660 nm
- Penetration depth: Up to 5–10 mm (reaches skin and shallow tissues)
- 가장 좋습니다:
- 피부 회춘
- 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 cytochrome c oxidase in your cells’ mitochondria, boosting ATP (에너지) 생산 and accelerating cell repair.
2️⃣ Near-Infrared (근적외선) 범위: 800–900 nm
- Common therapeutic wavelengths: 810 nm, 830 nm, 850 nm, 880 nm
- Penetration depth: Up to 30–40 mm (reaches muscles, 관절, 심지어 뼈까지)
- 가장 좋습니다:
- 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 (좋다 MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.
✅ 660 nm (빨간색): boosts skin health and surface healing
✅ 850 nm (근적외선): targets deeper tissues and muscles
함께, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.
4️⃣ Summary Table
| 파장 (nm) | Type of Light | 침투 깊이 | Primary Benefits |
|---|---|---|---|
| 630 nm | 빨간색 | 얕은 | Skin healing, pigmentation repair |
| 660 nm | 빨간색 | Medium | Collagen boost, 노화 방지 |
| 810 nm | 근적외선 | Deep | Nerve regeneration, circulation |
| 830 nm | 근적외선 | Deep | 통증 완화, 염증 |
| 850 nm | 근적외선 | Very Deep | 근육 회복, tissue repair |
✅ In Short
그만큼 최고의 파장 for red light therapy are 660 nm 그리고 850 nm, often used together for maximum skin and body benefits.
