Treatment Overview
Collagen Stimulator Injections are advanced injectable treatments that improve acne scars by triggering the skin’s natural collagen production rather than simply filling scars temporarily.
The most commonly used collagen stimulators in Korea include:
- Sculptra (Poly-L-Lactic Acid, PLLA)
- Radiesse (Calcium Hydroxylapatite, CaHA)
- Ellansé (Polycaprolactone, PCL microspheres)
Unlike hyaluronic acid (HA) fillers that dissolve within months, these stimulators work gradually to rebuild dermal structure and smooth out depressed acne scars over time.
Korean dermatologists often combine collagen stimulators with subcision, microneedling RF, PRP, or CO₂ fractional laser for synergistic results.
Purpose & Benefits
- Scar Remodeling: Stimulates new collagen to fill in depressed acne scars.
- Long-Lasting Results: Effects can last 2–4 years depending on the product.
- Natural-Looking Improvement: Gradual skin thickening without overfilled look.
- Skin Texture Enhancement: Improves firmness, elasticity, and smoothness.
- Versatility: Works well for rolling and boxcar scars.
- Synergy: Boosts the effectiveness of lasers or subcision.
Ideal Candidates
Collagen Stimulator Injections in Korea for acne scars are recommended for:
- Patients with moderate to severe depressed scars (rolling, boxcar).
- Adults who want a longer-lasting alternative to HA fillers.
- Individuals seeking gradual, natural scar improvement.
- Those open to multi-step combination protocols for optimal results.
Comparison with Other Treatments:
- Collagen Stimulators (Sculptra, Radiesse, Ellansé): Best for long-term collagen regeneration.
- Bellafill: Long-lasting filler (up to 5 years) but requires allergy test.
- HA Fillers: Short-term, reversible, good for testing results.
- Fractional CO₂ / Fraxel: Best for texture + scar resurfacing.
- Subcision: Best for tethered, deep scars—often paired with injectables.
Possible Risks & Complications
When performed by skilled dermatologists, collagen stimulators are very safe. Potential side effects include:
- Redness & Swelling: Common, lasts 1–3 days.
- Bruising or Tenderness: Temporary.
- Nodules or Lumps (rare): Avoided with correct injection technique.
- Allergic Reactions: Rare, since stimulators are biocompatible materials.
Treatment Techniques Used
- Subcision + Collagen Stimulator: Frees tethered scars before injection.
- Deep Dermal Injections: Product placed under scars to stimulate regeneration.
- Layered Approach: Different depths targeted for scar lifting and texture repair.
- Session Protocol: Usually 2–3 sessions spaced 4–6 weeks apart.
- Combination Therapy: Often paired with microneedling RF, PRP, or CO₂ laser.
Recovery & Aftercare
- Immediately: Mild redness, swelling, or bruising.
- 1–3 Days: Injection sites settle, skin feels firmer.
- 4–8 Weeks: Progressive scar softening and texture improvement.
- 3–6 Months: Maximum collagen regeneration results become visible.
Aftercare Tips:
- Massage injection areas gently (if recommended by doctor).
- Avoid strenuous exercise, alcohol, or saunas for 24–48 hours.
- Apply SPF 50+ sunscreen daily to protect healing skin.
- Stay hydrated to support collagen synthesis.
Results & Longevity
- Short-Term (1 Month): Early skin plumping and firmness.
- Medium-Term (3–6 Months): Significant scar reduction and smoother texture.
- Long-Term: Results last 2–4 years depending on product used.
