빨간불 치료 (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.
적색광 요법의 작동 방식
적색광 요법이 사용됩니다 빨간색의 특정 파장 (630–700 nm) 그리고 근적외선 (800–1000 nm) light to penetrate the skin and stimulate cell energy (ATP 생산).
These wavelengths reach deep into tissues, promoting:
- 콜라겐 생산
- Circulation and oxygen flow
- Muscle recovery and pain relief
하지만, 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:
- 빨간불 (보이는) is easily absorbed or reflected by fabric fibers.
- 근적외선 조명 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. 그러므로, treatments should always be done on bare skin for maximum effect.
결과를 최대화하는 방법
- Expose the target area directly to the light.
- Remove or roll up clothing to allow full coverage.
- Follow device distance recommendations (보통 6~12인치).
- Use consistent sessions — about 10–20 minutes, 3일주일에 –5 번.
결론
빨간불 치료 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.
