O best wavelength for red light therapy (Rlt) depends on your goal, but the most effective ranges are:
- Luz vermelha: 630–660 nm → ideal for skin surface treatments, produção de colágeno, antienvelhecimento, and pigmentation.
- Infravermelho próximo (Nir) luz: 810–850 nm → penetrates deeper tissues, supporting muscle recovery, joint health, Redução de inflamação, e alívio da dor.
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 Mitocôndrias to produce ATP (energia celular).
- Different wavelengths penetrate different depths:
- Luz vermelha (630–660nm): ~5–10 mm deep → surface skin, dermis, and collagen layers.
- Infravermelho próximo (810–850nm): ~30–50 mm deep → muscles, articulações, tendões, e ligamentos.
Choosing the correct wavelength ensures that the light reaches the tissues you want to treat.
Recommended Wavelengths by Goal
| Goal | Best Wavelength | Por que |
|---|---|---|
| Antienvelhecimento & rejuvenescimento da pele | 630–660nm | Estimula o colágeno & elastin in dermis |
| Scar & Hiperpigmentação | 630–660nm | Promotes skin repair & balances melanin |
| Recuperação muscular & dor nas articulações | 810–850nm | Penetrates deep tissue for healing & circulation |
| Inflamação & cicatrização de feridas | 630–850nm (combined) | Targets both surface and deep layers |
| Crescimento do cabelo | 630–680 nm | Stimulates follicles at skin surface |
Most high-quality RLT devices combine vermelho + infravermelho próximo for broader benefits.
Usage Tips for Optimal Results
- Distância: Keep 6–12 inches from the skin for consistent coverage.
- Duração: 10–20 minutos por sessão, depending on body area.
- Freqüência: 3–5 times per week for best results.
- Device Choice: Look for clinical-grade devices with 660 nm vermelho + 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.
Resumindo
The “best wavelength” depends on your treatment goal:
- 630–660 nm red light → skin, antienvelhecimento, pigmentation
- 810–850 nm near-infrared → deep tissue, alívio da dor, Recuperação muscular
Devices combining both wavelengths, como Sistemas de terapia de luz vermelha MERICAN, deliver the most versatile and effective treatment for full-body wellness.
