Rotlichttherapie (RLT) is praised for its benefits — from improving skin tone and collagen to easing muscle pain. But many users wonder: can red light therapy work through clothing, or does the fabric block its effects? Understanding how light interacts with skin and materials helps you get the most from your sessions.
Wie die Rotlichttherapie funktioniert
Rotlichttherapie verwendet bestimmte Wellenlängen von Rot (630–700 nm) Und Nahinfrarot (800–1000 nm) light to penetrate the skin and stimulate cell energy (ATP -Produktion).
These wavelengths reach deep into tissues, fördern:
- Kollagenproduktion
 - Circulation and oxygen flow
 - Muscle recovery and pain relief
 
Jedoch, the light must reach your skin directly for these effects to occur.
Does It Work Through Clothing?
🔬 The Science Says No
Most fabrics — even thin cotton or spandex — block or scatter red and infrared light, preventing the wavelengths from reaching your skin effectively.
Research shows that:
- Rotlicht (visible) is easily absorbed or reflected by fabric fibers.
 - Nahinfrarotlicht can pass through some very thin materials, but only a small fraction of its energy reaches the skin.
 
⚠️ Why Direct Exposure Matters
If the light can’t reach your skin, cells can’t absorb it, and no therapeutic benefits occur. daher, treatments should always be done on bare skin for maximum effect.
How to Maximize Results
- Expose the target area directly to the light.
 - Remove or roll up clothing to allow full coverage.
 - Follow device distance recommendations (usually 6–12 inches).
 - Use consistent sessions — about 10–20 minutes, 3–5 Mal pro Woche.
 
Abschluss
Rotlichttherapie does not work effectively through clothing because fabric blocks most therapeutic wavelengths. For the best results, always treat bare skin directly — ensuring the light energy reaches the target tissue.
