What NM Is Best for Red Light Therapy?

العلاج بالضوء الأحمر (rlt) typically works within the visible red and near-infrared (نير) spectrum of light, measured in نانومتر (نانومتر).
These wavelengths penetrate the skin at different depths and trigger various biological effects.

1️⃣ Red Light Range: 620-700 نانومتر

• Common therapeutic wavelengths: 630 نانومتر و 660 نانومتر
• Penetration depth: حتى 5–10 mm (reaches skin and shallow tissues)
• Best for:
  • تجديد الجلد
  • Collagen stimulation
  • تقليل الخطوط الدقيقة والتجاعيد
  • 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, تعزيز ATP (طاقة) إنتاج and accelerating cell repair.

2️⃣ Near-Infrared (نير) يتراوح: 800–900 nm

• Common therapeutic wavelengths: 810 نانومتر, 830 نانومتر, 850 نانومتر, 880 نانومتر
• Penetration depth: حتى 30–40 mm (reaches muscles, المفاصل, وحتى العظام)
• Best for:
  • 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 (يحب MERICAN red light beds) use a combination of 660 نانومتر + 850 نانومتر LEDs — the most studied and clinically effective pair.

✅ 660 نانومتر (أحمر): boosts skin health and surface healing
✅ 850 نانومتر (بالقرب من الأشعة تحت الحمراء): targets deeper tissues and muscles

معاً, they provide comprehensive whole-body benefits, from skin rejuvenation to muscle recovery and inflammation reduction.

4️⃣ Summary Table

✅ In Short

ال best wavelengths for red light therapy are 660 نانومتر و 850 نانومتر, often used together for maximum skin and body benefits.
