Stretch marks, or striae, are common skin concerns caused by rapid stretching of the skin during pregnancy, weight gain, or growth spurts. Many people wonder if red light therapy (RLT) can help improve their appearance.
The answer is yes—red light therapy may reduce the visibility of stretch marks by stimulating skin repair and collagen production.
How Red Light Therapy Works on Stretch Marks
Red light therapy uses low-level red and near-infrared light (630–850nm) to penetrate the skin and activate cellular processes:
-
Stimulates Collagen & Elastin Production
-
Collagen and elastin are proteins that support skin structure.
-
RLT encourages fibroblasts to produce more collagen, helping the skin regain elasticity.
-
-
Improves Blood Circulation
-
Enhanced blood flow delivers oxygen and nutrients to affected areas.
-
This helps repair damaged skin tissue more effectively.
-
-
Reduces Inflammation
-
RLT can calm skin irritation and redness associated with new or inflamed stretch marks.
-
-
Enhances Skin Tone & Texture
-
Regular sessions may improve overall skin smoothness, making stretch marks less noticeable.

Final Verdict
Red light therapy cannot completely remove stretch marks, but it can significantly improve their appearance over time. By stimulating collagen, enhancing circulation, and improving skin elasticity, RLT is a safe and effective tool to complement other skincare treatments.
FAQ
Q1: Can red light therapy prevent stretch marks?
Yes, it may help maintain skin elasticity, but rapid stretching is the main cause, so prevention is not guaranteed.
Q2: Are results permanent?
Results are long-lasting but maintaining healthy skin and consistent use helps sustain improvements.
Q3: Can I combine RLT with creams or oils?
Yes, combining RLT with moisturizing or collagen-boosting products may enhance results.
Q4: When will I see results?
Typically 6–12 weeks, depending on severity and consistency.
