IL best wavelength for red light therapy (RLT) depends on your goal, but the most effective ranges are:
- Luce rossa: 630–660 nm → ideal for skin surface treatments, produzione di collagene, anti-invecchiamento, and pigmentation.
- Vicino a infrarossi (Nir) leggero: 810–850 nm → penetrates tessuti più profondi, supporting muscle recovery, Salute congiunta, riduzione dell’infiammazione, e sollievo dal dolore.
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, stimolante mitocondri to produce ATP (energia cellulare).
- Different wavelengths penetrate different depths:
- Luce rossa (630–660 nm): ~5–10 mm deep → surface skin, dermis, and collagen layers.
- Vicino a infrarossi (810–850 nm): ~30–50 mm deep → muscles, articolazioni, tendini, and ligaments.
Choosing the correct wavelength ensures that the light reaches the tissues you want to treat.
Recommended Wavelengths by Goal
| Obiettivo | Best Wavelength | Perché |
|---|---|---|
| Antietà & Ringiovanimento della pelle | 630–660 nm | Stimola il collagene & elastin in dermis |
| Scar & iperpigmentazione | 630–660 nm | Promotes skin repair & balances melanin |
| Recupero muscolare & dolore articolare | 810–850 nm | Penetrates deep tissue for healing & circolazione |
| Infiammazione & guarigione delle ferite | 630–850 nm (combined) | Targets both surface and deep layers |
| Crescita dei capelli | 630–680 nm | Stimulates follicles at skin surface |
Most high-quality RLT devices combine rosso + vicino infrarosso for broader benefits.
Usage Tips for Optimal Results
- Distanza: Keep 6–12 inches from the skin for consistent coverage.
- Durata: 10–20 minuti per sessione, depending on body area.
- Frequenza: 3–5 times per week for best results.
- Device Choice: Look for clinical-grade devices with 660 NM rosso + 850 nm NIR LEDs — this combination covers most therapeutic needs.
Important Considerations
- Too low intensity or wrong wavelength → limited or no results.
- Sovraesposizione is generally safe but unnecessary; stick to recommended session times.
- Terapia di combinazione often works best — e.g., skin treatments with 660 nm and deeper joint treatments with 850 nm.
Bottom Line
The “best wavelength” depends on your treatment goal:
- 630–660 nm red light → skin, anti-invecchiamento, pigmentation
- 810–850 nm near-infrared → deep tissue, sollievo dal dolore, recupero muscolare
Devices combining both wavelengths, Piace MERICAN red light therapy systems, deliver the most versatile and effective treatment for full-body wellness.
