스트레치 마크, also known as 스트라이아, form when the skin stretches too quickly during pregnancy, rapid weight gain, 또는 성장 분출. They often appear as 빨간색, purple, or white lines on the abdomen, 허벅지, hips, or arms. While harmless, many people seek ways to reduce their appearance.
One of the most promising options is red light therapy (RLT), which stimulates 콜라겐 생산—a key factor in improving skin elasticity and reducing stretch marks.
How Collagen Helps With Stretch Marks
- Collagen = Skin’s Support System
Collagen is a structural protein that keeps skin firm, smooth, and elastic. - When the skin stretches too quickly, collagen and elastin fibers break, leaving behind visible marks.
- Increasing collagen levels helps repair damaged tissue and restore smoother texture.
How Red Light Therapy Boosts Collagen
Red light therapy uses low-level red and near-infrared light (630–850nm) that penetrates the skin and stimulates mitochondria in cells. This increases ATP (세포 에너지), which powers the body’s natural repair processes.
Key effects on collagen:
- Activates Fibroblasts → the cells responsible for producing collagen and elastin.
- Increases Collagen Density → making the skin stronger and more elastic.
- Improves Circulation → delivers nutrients and oxygen to help rebuild skin tissue.
- Smooths Texture → gradually reduces the depth and visibility of stretch marks.
Benefits of Red Light Therapy for Stretch Marks
- Stimulates new collagen production
- Improves skin elasticity and firmness
- Reduces the color contrast of stretch marks (fading red/purple marks faster)
- Smooths rough or depressed skin texture
- 비침습적, safe for most skin types, and drug-free

FAQ
Q1: Can red light therapy completely remove stretch marks?
아니요, but it can significantly reduce their visibility and improve skin smoothness.
Q2: Does collagen really work on old stretch marks?
Collagen stimulation is more effective on 최신 (빨간색/보라색) marks, but even older white marks can appear softer and less noticeable.
Q3: How long before I see results?
Most people notice improvement after 6–12 weeks of consistent therapy.
Q4: Can I combine red light therapy with collagen supplements or creams?
예. Using RLT alongside collagen peptides or topical creams may enhance results.
Final Takeaway
Red light therapy helps reduce stretch marks by stimulating collagen production, improving elasticity, and enhancing skin repair. While it may not erase stretch marks completely, consistent use can lead to smoother, firmer, and more even-toned skin.
