Rejuran Acne Scar Repair: PDRN Rebuilds Skin Regeneration to Smooth Scars






Rejuran Acne Scar Repair: PDRN Rebuilds Skin Regeneration to Smooth Scars



Acne scars are a lasting concern long after breakouts end. Repeated inflammatory acne destroys dermal collagen structure, leaving depressed scars — ice pick, boxcar, and rolling types — that make skin surface appear uneven. Traditional chemical peels and dermabrasion offer limited results with long recovery. Seoul’s Rappoel Dermatology uses Rejuran PDRN injection to activate dermal repair mechanisms at the cellular level, promoting collagen regeneration to improve acne scars from within.

Three Main Types of Acne Scars

  • Ice Pick: Deep, narrow depressions under 2mm diameter, resembling ice pick punctures, most challenging to treat
  • Boxcar: Wide, shallow rectangular depressions with defined edges, 1.5-4mm diameter, respond well to PDRN
  • Rolling: Wide, irregular depressions with模糊 edges, caused by dermal-subcutaneous tethering, requires combination with subcision
  • Hypertrophic: Raised rather than depressed scars, common on chest and back, not suitable for PDRN injection
  • Post-Inflammatory Hyperpigmentation: Red or brown marks left after acne resolves, PDRN can accelerate fading

How Rejuran PDRN Repairs Acne Scars

  1. DNA Repair Activation: PDRN (Polydeoxyribonucleotide) derived from salmon testes activates cellular A2A receptors, promoting DNA repair and cell regeneration
  2. Collagen Rebuilding: Stimulates dermal fibroblasts to produce new Type I and Type III collagen, filling depressions
  3. Anti-inflammatory Repair: Reduces chronic inflammation in scar areas, improving local microenvironment
  4. Angiogenesis: Promotes microvascular formation in scar areas, improving local nutrition supply and skin tone
  5. Skin Barrier Repair: Strengthens stratum corneum barrier function, reducing moisture loss and improving overall skin quality

Rappoel’s Acne Scar Repair Program

  • Type Assessment: Doctor examines scar types and depth using dermoscopy to create a personalized plan
  • Rejuran Injection: Using water-shine gun or manual injection, PDRN is evenly injected into the dermis of scar areas
  • Combined Therapy: Ice pick scars combined with TCA chemical reconstruction; rolling scars combined with subcision
  • Course Design: Every 2-4 weeks, typically 3-5 sessions for a complete course
  • Aftercare: No makeup or water contact for 24 hours, enhanced sun protection and moisturizing
  • Results Timeline: Visible improvement after 2nd session, optimal results at 3-6 months

Rejuran acne scar repair works at the cellular level rather than physical ablation. PDRN not only improves depressions but also enhances skin tone and texture in scar areas, making overall skin more uniform and refined. Rappoel Clinic is located 3 minutes from Gangnam Station Exit 10, where doctors create combined treatment plans based on your specific scar types for optimal repair results.

Frequently Asked Questions

How many Rejuran sessions are needed to see acne scar improvement?
Initial improvement is typically visible after the 2nd session (about 4-6 weeks). Boxcar scars respond best to PDRN, with noticeable improvement after 3 sessions. Ice pick scars require combination with TCA chemical reconstruction for a longer course. A complete course is usually 3-5 sessions every 2-4 weeks, with optimal results at 3-6 months.
Is Rejuran acne scar treatment painful?
When using the water-shine gun, topical numbing cream is applied for 20-30 minutes, making pain very low. Manual injection in scar areas may cause mild discomfort but is well tolerable. Post-injection redness and minor pinpoint bleeding typically resolve within 24-48 hours.
Which is better for acne scars: Rejuran or laser resurfacing?
They work differently. Laser resurfacing physically removes epidermis and superficial dermis for faster results but with longer recovery (7-14 days) and pigmentation risk. Rejuran promotes repair at the cellular level with shorter recovery (1-2 days), suitable for Asian skin. The best approach combines both — Rejuran first to improve skin foundation, then selective laser for stubborn scars.
Are Rejuran acne scar results permanent?
Rejuran promotes your own collagen regeneration, and new collagen is permanent. However, skin continues to age, so maintenance treatments every 3-6 months after completing the course are recommended. Proper sun protection and skincare, plus preventing new acne, help maintain results.
Do I need an appointment for Rejuran acne scar 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, as the first visit requires detailed scar assessment and treatment planning. Clinic hours are 10 AM to 7 PM daily.
