The best wavelength for red light therapy (RLT) depends on your goal, but the most effective ranges are:
- 赤信号: 630–660 nm → ideal for skin surface treatments, コラーゲン生産, アンチエイジング, と色素沈着.
- 近赤外線 (nir) ライト: 810–850 nm → penetrates より深い組織, supporting muscle recovery, 共同健康, 炎症の軽減, そして痛みの軽減.
Many professional devices combine both red and NIR wavelengths for full-body or targeted therapy.
Why Wavelength Matters
Red light therapy works by delivering photons to cells, stimulating ミトコンドリア to produce ATP (細胞エネルギー).
- Different wavelengths penetrate different depths:
- 赤信号 (630–660 nm): ~5–10 mm deep → surface skin, dermis, and collagen layers.
- 近赤外線 (810–850 nm): ~30–50 mm deep → muscles, 関節, 腱, and ligaments.
Choosing the correct wavelength ensures that the light reaches the tissues you want to treat.
Recommended Wavelengths by Goal
| ゴール | Best Wavelength | Why |
|---|---|---|
| アンチエイジング & 皮膚の若返り | 630–660 nm | コラーゲンを刺激します & elastin in dermis |
| Scar & 色素沈着過剰 | 630–660 nm | Promotes skin repair & balances melanin |
| 筋肉の回復 & 関節痛 | 810–850 nm | Penetrates deep tissue for healing & 循環 |
| 炎症 & 創傷治癒 | 630–850 nm (combined) | Targets both surface and deep layers |
| 発毛 | 630–680 nm | Stimulates follicles at skin surface |
Most high-quality RLT devices combine 赤 + 近赤外 for broader benefits.
Usage Tips for Optimal Results
- 距離: Keep 6–12 inches from the skin for consistent coverage.
- 間隔: 10–20分間セッション, depending on body area.
- 頻度: 3最良の結果を得るには、週5回.
- Device Choice: Look for clinical-grade devices with 660 nmレッド + 850 nm NIR LEDs — this combination covers most therapeutic needs.
Important Considerations
- Too low intensity or wrong wavelength → limited or no results.
- Overexposure is generally safe but unnecessary; stick to recommended session times.
- Combination therapy often works best — e.g., skin treatments with 660 nm and deeper joint treatments with 850 nm.
結論
The “best wavelength” depends on your treatment goal:
- 630–660 nm red light → skin, アンチエイジング, pigmentation
- 810–850 nm near-infrared → deep tissue, 痛みの緩和, 筋肉の回復
Devices combining both wavelengths, のように MERICAN 赤色光療法システム, deliver the most versatile and effective treatment for full-body wellness.
