Treatment Overview
Rejuran S is a specialized PN (polynucleotide) skin booster developed specifically for acne scar treatment. Offered widely in Korean dermatology clinics, it differs from the standard Rejuran Healer by having a more concentrated and viscous formulation, allowing it to target atrophic scars with greater precision.
Derived from salmon DNA, Rejuran S stimulates fibroblast activity, collagen remodeling, and tissue regeneration. It is commonly used as an injectable treatment for rolling, boxcar, and shallow icepick scars, and is often combined with Juvelook, lasers, microneedling, or subcision for enhanced results.
Purpose & Benefits
- Scar Remodeling: Promotes fibroblast activity and collagen deposition to lift depressed scars.
- Skin Healing: Accelerates tissue repair and regeneration.
- Pigmentation Control: Reduces PIH (post-inflammatory hyperpigmentation) following acne.
- Texture Refinement: Smooths rough surfaces and minimizes pore visibility.
- Inflammation Reduction: Calms redness and irritation associated with acne damage.
- Combination Advantage: Works synergistically with Juvelook and exosomes for optimal outcomes.
Ideal Candidates
Rejuran S in Korea is recommended for:
- Patients with atrophic acne scars (rolling, boxcar, mild icepick).
- Individuals with post-acne pigmentation and redness.
- Patients who experienced slow recovery or irritation from lasers alone.
- Those seeking a regenerative, scar-focused injectable.
- Individuals with sensitive or Asian skin needing a safe, biocompatible treatment.
Possible Risks & Complications
Rejuran S is generally safe, but mild side effects may occur:
- Redness, swelling, or bruising at injection points.
- Pinpoint bumps that resolve within 1–3 days.
- Mild tenderness or itching during recovery.
- Rare nodules or unevenness if injected too superficially.
- Low risk of PIH, minimized with strict aftercare and sun protection.
Surgical Techniques Used
- Injection Method: Direct microinjections into depressed scars or dermis.
- Formulation: Concentrated PN (polynucleotides) for scar repair.
- Combination Therapy: Often paired with Juvelook, fractional CO₂ lasers, RF microneedling, or subcision for deeper scars.
- Protocol: Typically 3–4 sessions, spaced 4–6 weeks apart. Maintenance suggested annually.
Recovery & Aftercare
- Immediately: Redness, mild swelling, or small bumps at injection sites.
- 1–3 Days: Skin begins to calm, texture feels smoother.
- 1 Week: Noticeable improvement in hydration and tone.
- 1–6 Months: Progressive collagen remodeling reduces scar depth.
Aftercare Tips:
- Avoid makeup for 24–48 hours post-injection.
- Keep skin moisturized with barrier creams.
- Avoid acids, scrubs, and retinoids for 5–7 days.
- Apply SPF 50+ sunscreen daily.
- Avoid hot baths, saunas, and strenuous workouts for 1–2 days.
Results & Longevity
- After 1 Session: Skin feels calmer, scars slightly softened.
- After 2 Sessions: Visible reduction in scar depth and redness.
- After 3–4 Sessions: Long-term improvement in scar remodeling and overall skin quality.
- Longevity: Results typically last 12–18 months, with maintenance every 12 months.
