Strekkmerker (streker) er et vanlig hudproblem forårsaket av rask strekking av huden på grunn av graviditet, vektendringer, eller vekstspruter. Mens de er ufarlige, many seek ways to reduce their appearance.Kan rødlysterapi (RLT) hjelp? Her er hva vitenskapen sier.
1. How Red Light Therapy May Improve Stretch Marks
RLT works by stimulatingproduksjon av kollagen og elastin, key proteins that keep skin firm and elastic. Research suggests it may help by:
✔Increasing collagen synthesis – Thickens skin and improves texture.
✔Enhancing blood flow – Promotes healing and skin regeneration.
✔Redusere betennelse – Helps fade red/purple stretch marks (striae rubra).
Klinisk bevis
- EN 2023 Journal of Cosmetic Dermatology study found RLT improved skin elasticity and reduced stretch mark depth etter 12 uker.
- Nær-infrarød (NIR) light may trenge dypere inn to remodel connective tissue.
2. Best Red Light Therapy Protocols for Stretch Marks
EN. Wavelengths to Use
- Rødt lys (630-660 nm) – Best for surface-level collagen stimulation.
- Nær-infrarød (810-850 nm) – Targets deeper tissue for severe or older stretch marks (striae alba).
B. Treatment Frequency & Varighet
- 3-5 sessions per week (konsistens er nøkkelen).
- 5-15 minutes per area (depending on device power).
- Minimum 8-12 uker for visible results.
C. Device Recommendations
- Handheld RLT devices (f.eks., Joovv Go, Mito rødt lys) – For small areas.
- Large LED panels – For broader coverage (f.eks., lårene, mage).
- Professional in-office treatments – More powerful (f.eks., LED light beds).
3. How to Maximize Results
✅Exfoliate first – Removes dead skin for better light absorption.
✅Use hyaluronic acid or vitamin C serum – Enhances collagen effects.
✅Combine with microneedling or retinoids – Boosts skin remodeling (check with a dermatologist).
🚫Avoid sunburn/tanning – Can worsen stretch mark contrast.
4. Realistiske forventninger
- Best for newer (rød/lilla) strekkmerker – More responsive than old (white/silver) ones.
- Gradual improvement – Unlike lasers, RLT works slowly but safely.
- May not fully erase deep scars but can significantly reduce visibility.
Before & After: Hva du kan forvente
| Timeframe | Resultater |
|---|---|
| 4-6 uker | Forbedret hudtekstur, slight fading |
| 8-12 uker | Noticeable reduction in color/depth |
| 6+ måneder | Optimal results (with consistent use) |
5. Alternativ & Komplementære behandlinger
If RLT isn’t enough, consider combining with:
- Fractional lasers (f.eks., Fraxel) – For deeper scars.
- Microdermabrasion – Exfoliates top layers.
- Topical retinoids – Promotes cell turnover (avoid during pregnancy).
Endelig dom
✔RLT is a safe, non-invasive option to improve stretch marks, especially when started early.
✔Konsistens er avgjørende—results take weeks to months.
✔For best outcomes, pair with skincare and professional treatments.
Try this routine:
- Exfoliate 2x/week.
- Apply RLT 5-10 mins daily (660nm + 850nm).
- Moisturize with collagen-boosting creams.
