Rejuran for Stretch Marks: How PDRN Improves Abdominal Skin Texture






Rejuran for Stretch Marks: How PDRN Improves Abdominal Skin Texture



Stretch marks (striae) are scar tissue formed when the dermis tears due to rapid skin stretching, commonly on the abdomen, thighs, and buttocks. Traditional topical creams only moisturize the surface and cannot reach the structural damage in the dermis. Korean Rejuran contains Polydeoxyribonucleotide (PDRN) extracted from salmon DNA, which can be injected directly into the dermis to promote collagen regeneration and tissue repair. Seoul’s Rappoel Dermatology offers Rejuran stretch mark repair treatments to help postpartum women regain smoother abdominal skin.

How Stretch Marks Form

  • Red Striae (Early Stage): Fresh dermal tears with exposed capillaries, appearing red or purple — best treatment window
  • White Striae (Stable Phase): Scar tissue formed, blood vessels contracted, appearing white or silvery with visible indentation
  • Core Problem: Not a surface issue but structural breakage of collagen and elastin fibers in the dermis
  • Traditional Limitation: Topical lotions only moisturize the epidermis and cannot reach the dermis for structural repair

How Rejuran PDRN Repairs Stretch Marks

  1. Tissue Repair Signaling: PDRN activates adenosine A2A receptors, promoting fibroblast proliferation and collagen synthesis
  2. Angiogenesis: Promotes new blood vessel formation, improving local circulation to fade red striae faster
  3. Anti-inflammatory: Reduces chronic dermal inflammation, preventing further deterioration
  4. Deep Injection: Using micro-injections or mesotherapy devices to deliver PDRN into mid-to-deep dermis
  5. Gradual Improvement: Each treatment triggers a new round of collagen production, progressively lightening and narrowing the marks

Rejuran is a PDRN product by Korean company Hugel, widely used in Korea for various skin repair needs. Stretch mark repair requires patience — marks will not completely disappear, but consistent treatment can significantly improve texture and color, making them much less noticeable. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10 in Seoul, offering professional postpartum skin repair solutions.

Frequently Asked Questions

Can Rejuran completely remove stretch marks?
It cannot completely remove them, but it can significantly improve them. Stretch marks are fundamentally scar tissue in the dermis, and no treatment can make them completely disappear. Rejuran PDRN can improve their color (fade from red/white), width (narrower), and texture (from indented to smoother). Typically, 3-5 sessions achieve satisfactory improvement.
How long after giving birth can I start Rejuran stretch mark treatment?
For natural delivery, we recommend waiting at least 3 months; for C-section, at least 6 months. The body needs to fully recover and wounds must be completely healed. Rejuran injections are safe during breastfeeding since PDRN is a natural DNA fragment, but consult the doctor first about your individual situation.
Is Rejuran treatment for stretch marks painful?
Abdominal skin is relatively less sensitive, and topical numbing cream is applied for 20-30 minutes before treatment. Pain is minimal. Micro-injections cause only mild pinching, and mesotherapy devices are even more comfortable. Mild redness may last 1-2 days but does not affect daily activities.
How many sessions are needed for results?
Red striae (early stage) typically show visible improvement after 3 sessions; white striae (stable phase) require 5 sessions for a complete course. Sessions are spaced 3-4 weeks apart. Results vary by individual skin condition, depth, and age of the marks. Earlier treatment yields better results, as collagen repair capacity is stronger in the red striae phase.
Do I need an appointment for stretch mark treatment in Korea?
Yes. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10 in Seoul. Book via WeChat (rappoelkr) or Line (rappoelkr). We recommend booking 1-2 weeks in advance and mentioning stretch mark treatment so the clinic allocates sufficient time (about 40 minutes). Clinic hours are 10 AM to 7 PM daily.
