Rotlichttherapie (RLT), auch bekannt als low-level light therapy (Lllt) oder Photobiomodulation, uses specific wavelengths of red and near-infrared light (usually 630–660 nm for red and 810–850 nm for near-infrared) to stimulate cellular processes, accelerate healing, and improve overall tissue function.
It is backed by decades of research in dermatology, Sportmedizin, and regenerative medicine.
Wie die Rotlichttherapie funktioniert
RLT works at the cellular level, primarily affecting the Mitochondrien — the “powerhouse” of cells.
- Photon absorption:
- Red and near-infrared photons penetrate skin and tissues.
- Cells absorb these photons through cytochrome c oxidase, an enzyme in the mitochondrial respiratory chain.
- Increased ATP production:
- Photon absorption stimulates mitochondria to produce more ATP (Adenosintriphosphat) — the energy molecule of cells.
- More ATP means cells have more energy to repair, regenerate, and function efficiently.
- Cellular signaling & gene expression:
- RLT modulates reactive oxygen species (Ros) and nitric oxide (NEIN) in cells.
- This reduces inflammation, improves circulation, and activates repair genes.
Biological Effects of Red Light Therapy
| Effect | How It Works | Vorteile |
|---|---|---|
| Collagen & elastin stimulation | Activates fibroblasts | Firmer, tighter, younger-looking skin |
| Wundheilung & Gewebereparatur | Increases ATP & Blutfluss | Faster recovery from injuries, Narben, and burns |
| Reduzierte Entzündungen | Modulates ROS & inflammatory cytokines | Eases arthritis, Muskelkater, and inflammatory skin conditions |
| Schmerzlinderung | Improves circulation and nerve function | Helps chronic pain, joint discomfort, and post-exercise soreness |
| Enhanced circulation | Increases nitric oxide and microvascular flow | Improves oxygen & nutrient delivery, supports tissue repair |
| Hair growth stimulation | Activates follicle cells | Helps androgenic alopecia or hair thinning |
Tiefe & Wellenlänge ist wichtig
- Rotlicht (630–660 nm): Eindringt superficial layers (~5–10 mm) — ideal for skin, collagen, and pigmentation.
- Nahinfrarot (810–850 nm): Eindringt Tiefere Gewebe (~30–50 mm) — effective for joints, Muskeln, Sehnen, and nerve repair.
Most clinically effective devices combine both red and near-infrared wavelengths to target surface and deep tissues simultaneously.
Supporting Scientific Evidence
- Hautverjüngung: Multiple studies show reduzierte Falten, Verbesserte Hautelastizität, and faster healing of scars.
- Pain & Entzündung: Randomized trials demonstrate reduced joint pain and stiffness in arthritis and tendonitis.
- Wundheilung: Studies in burns and surgical wounds show faster tissue repair.
- Hair regrowth: Clinical trials show increased hair density in androgenic alopecia.

How to Maximize Effectiveness
- Wellenlänge: Use 630–660 nm red + 810–850 nm near-infrared for most benefits.
- Sitzungsdauer: 10–20 Minuten pro Bereich.
- Frequenz: 3–5 Mal pro Woche.
- Device quality: Choose devices with hohe Bestrahlung / Ausgabe for meaningful therapy.
Overexposure is generally safe but unnecessary — stick to recommended times and distance for best results.
Fazit
Red light therapy works by energizing cells, Entzündungen reduzieren, and enhancing repair mechanisms through photobiomodulation.
It has wide-ranging benefits for Haut, Muskeln, Gelenke, and overall cellular health, backed by scientific research and clinical trials.
Professional devices like MERICAN Rotlichttherapiesysteme kombinieren 660 nm red + 850 nm near-infrared LEDs, ensuring both surface skin and deep tissue benefits in one therapy session.
