Short answer:
Rejuran S is a denser polynucleotide (PN) formula from the Rejuran family that is injected directly under depressed acne scars to support tissue repair and help them fill in. Rejuran Healer is spread across the whole face to improve general skin quality. In Gangnam, Rejuran S typically costs ₩200,000–₩400,000 per session, usually needs about 3 sessions, and causes 1–3 days of bumps.
Rejuran S vs Rejuran Healer
- Purpose:
Rejuran S targets individual depressed scars; Rejuran Healer improves overall thickness, texture and resilience.
- Formula:
Rejuran S is more concentrated and viscous, so it stays where it is placed; Healer is thinner and spreads evenly.
- Technique:
Rejuran S is placed under each scar; Healer uses many even micro-injections across the face.
- Price in Gangnam:
Rejuran S ₩200,000–₩400,000; Rejuran Healer
₩150,000–₩400,000 per session.
How polynucleotides help scars
Polynucleotides are purified DNA fragments, in Rejuran's case from salmon. They are thought to create a supportive environment for the skin's own repair and collagen production. When placed beneath an atrophic scar, the goal is to rebuild the thin, depressed area gradually rather than simply fill it like a filler would.
Which scars respond best
- Shallow boxcar and rolling scars:
usually the best candidates.
- Scars after subcision:
Rejuran S is often injected straight after subcision
to support the released area.
- Deep icepick scars:
respond less well alone and usually need TCA CROSS.
The treatment process
- Scar mapping:
the doctor marks scars under angled light.
- Numbing:
cream for 30–40 minutes; some clinics add local anaesthetic.
- Injection:
small amounts are placed under each scar, usually 15–30 minutes.
- Calming care:
a soothing mask, then sunscreen.
Expect raised bumps for 1–3 days and possible small bruises. Most people return to normal activities the next day.
Sessions and results
A typical course is about 3 sessions spaced roughly 4 weeks apart. Change is gradual, with scars looking softer and shallower over 2–3 months. Results are long-term because the goal is tissue remodelling, though new acne can create new scars, so controlling active breakouts first matters.
