Stretch marks, also known as striae, form when the skin stretches too quickly during pregnancy, rapid weight gain, or growth spurts. They often appear as red, purple, or white lines on the abdomen, thighs, hips, or arms. While harmless, many people seek ways to reduce their appearance.
One of the most promising options is लाल प्रकाश चिकित्सा (आरएलटी), which stimulates collagen production—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 (cellular energy), 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
- Non-invasive, safe for most skin types, and drug-free

FAQ
Q1: Can red light therapy completely remove stretch marks?
नहीं, 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 नई (red/purple) 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?
हाँ. 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.
