El best wavelength for red light therapy (RLT) depends on your goal, but the most effective ranges are:
- Luz roja: 630–660 nm → ideal for skin surface treatments, producción de colágeno, antienvejecimiento, and pigmentation.
- Infrarrojo cercano (Nir) luz: 810–850 nm → penetrates tejidos más profundos, supporting muscle recovery, salud conjunta, reducción de la inflamación, y alivio del dolor.
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 mitocondrias to produce atp (energía celular).
- Different wavelengths penetrate different depths:
- Luz roja (630–660 nm): ~5–10 mm deep → surface skin, dermis, and collagen layers.
- Infrarrojo cercano (810–850 nm): ~30–50 mm deep → muscles, articulaciones, tendones, y ligamentos.
Choosing the correct wavelength ensures that the light reaches the tissues you want to treat.
Recommended Wavelengths by Goal
| Meta | Best Wavelength | Why |
|---|---|---|
| Antienvejecimiento & rejuvenecimiento de la piel | 630–660 nm | Estimula el colágeno & elastin in dermis |
| Scar & hiperpigmentación | 630–660 nm | Promotes skin repair & balances melanin |
| Recuperación muscular & dolor articular | 810–850 nm | Penetrates deep tissue for healing & circulación |
| Inflamación & curación de heridas | 630–850 nm (combined) | Targets both surface and deep layers |
| Crecimiento del cabello | 630–680 nm | Stimulates follicles at skin surface |
Most high-quality RLT devices combine rojo + infrarrojo cercano for broader benefits.
Usage Tips for Optimal Results
- Distancia: Keep 6–12 inches from the skin for consistent coverage.
- Duración: 10–20 minutos por sesión, depending on body area.
- Frecuencia: 3–5 times per week for best results.
- Device Choice: Look for clinical-grade devices with 660 nm rojo + 850 nm NIR LEDs — this combination covers most therapeutic needs.
Important Considerations
- Too low intensity or wrong wavelength → limited or no results.
- Sobreexposición 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 Nuevo Méjico.
Final
The “best wavelength” depends on your treatment goal:
- 630–660 nm red light → skin, antienvejecimiento, pigmentation
- 810–850 nm near-infrared → deep tissue, alivio del dolor, recuperación muscular
Devices combining both wavelengths, como Sistemas de terapia de luz roja MERICAN, deliver the most versatile and effective treatment for full-body wellness.
