What NM Is Best for Red Light Therapy?

Θεραπεία με κόκκινο φως (RLT) typically works within the visible red and near-infrared (NIR) spectrum of light, μετρηθεί σε νανόμετρα (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 και 660 nm
• Penetration depth: Μέχρι και 5–10 mm (reaches skin and shallow tissues)
• Best for:
  • Αναζωογόνηση του δέρματος
  • Collagen stimulation
  • Μείωση λεπτών γραμμών και ρυτίδων
  • 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 (ενέργεια) παραγωγή 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: Μέχρι και 30–40 mm (reaches muscles, αρθρώσεις, and even bones)
• Best for:
  • Muscle recovery and performance
  • Joint and deep tissue pain relief
  • Nerve regeneration
  • Βελτίωση της κυκλοφορίας και μείωση της φλεγμονής

🔬 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 (σαν MERICAN red light beds) use a combination of 660 nm + 850 nm LEDs — the most studied and clinically effective pair.

✅ 660 nm (κόκκινος): boosts skin health and surface healing
✅ 850 nm (κοντά στο υπέρυθρο): targets deeper tissues and muscles

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

4️⃣ Summary Table

✅ In Short

Ο best wavelengths for red light therapy are 660 nm και 850 nm, often used together for maximum skin and body benefits.
