Rejuran S for Depressed Scarsin Gangnam, Seoul
Rejuran S is a more concentrated, higher-viscosity polynucleotide (PN) formula made to target depressed, atrophic scars such as sunken acne scars. At QD Clinic in Gangnam, Seoul, it is injected into and beneath the scar to support the skin’s repair and help improve the appearance of the depressed area over a series of sessions. A session usually takes about 20–40 minutes including numbing. (Results vary by individual.)
Who it’s for
- Depressed, atrophic acne scars or other sunken scars
- Uneven skin texture caused by scarring
- Those who want to improve the appearance of scars without ablative laser, or alongside it
- People combining scar treatments in a longer plan
Scar type and whether Rejuran S is suitable are assessed during consultation; it does not remove scars entirely.
How it works
Rejuran S uses a more concentrated, higher-viscosity polynucleotide (PN) formula than the standard version, so it can be placed into and beneath depressed scars. The PN is thought to support the skin’s repair in the scarred area, helping to improve the texture and depth of atrophic scars gradually over several sessions. It is often considered as part of a broader scar plan and can be discussed alongside energy-based options such as microneedling radiofrequency. (“S” refers to the scar-focused formula.)
THE MECHANISM, STEP BY STEP
01A concentrated PN formula
Rejuran S uses a more concentrated, higher-viscosity polynucleotide (PN) formula than the standard version, so it can be placed into and beneath depressed scars.
02Supporting repair in the scar
The PN is thought to support the skin’s repair in the scarred area, working on the texture and depth of atrophic scars over time.
03Placed into and beneath the scar
Injections are directed into and under each depressed scar so the material supports the base of the depression.
04Why it takes several sessions
Scar remodeling follows the skin’s own timeline, so the texture improves gradually across a course rather than at once. (Results vary by individual.)
Treatment areas
- Acne-scarred cheeks
- Depressed acne scars on the cheeks.
- Individual depressed scars
- Single atrophic or sunken scars.
- Uneven texture
- Areas of scarring-related roughness, decided at consultation.
What the procedure is like
- 1Consultation and assessment of scar type
- 2Cleansing and numbing cream
- 3Injections into and beneath the depressed scars
- 4Cooling, soothing and aftercare guidance
Time: A session takes about 20–40 minutes, including numbing time.
Recovery & aftercare
- Little downtime; small raised bumps at the injection sites may appear and usually settle within about 1–2 days.
- Temporary redness, mild swelling, tenderness or minor bruising may occur.
- Avoid makeup, saunas and intense exercise briefly, use sun protection, and follow the guidance we provide.
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
DAY 0 Treatment day
Numbing first, then injections into and beneath the scars. Small raised bumps at the injection sites are common, with mild redness or swelling.
DAY 1-2 Bumps settling
The small bumps usually settle within about 1–2 days. Minor bruising, if any, starts to fade.
WEEK 2-4 Between sessions
Sessions are usually spaced 2–4 weeks apart. Early texture change is subtle and varies between people.
OVER A FEW MONTHS Gradual texture change
As the skin remodels across the course, the texture and depth of the scars may improve gradually. (Results vary by individual.)
AFTER THE COURSE Review & further sessions
Your doctor reviews the scars and discusses further sessions or a maintenance plan.
Sessions & results
Depressed scars usually need a course of several sessions spaced roughly 2–4 weeks apart, with the texture improving gradually over a few months. The number of sessions depends on the scars and is decided at consultation. (Results vary by individual.)
How it compares
These all work on the skin but target different things — from placing repair support into a scar to remodeling with energy — so the right approach depends on your scars.
| Comparison | Rejuran S | Rejuran Healer | Potenza |
|---|---|---|---|
| Main agent | Concentrated polynucleotides (from salmon DNA) | Polynucleotides, standard formula | Radiofrequency energy via microneedles |
| How it works | Placed into and beneath depressed scars | Supports overall skin repair across the face | Heats the dermis to remodel scar tissue |
| Often chosen for | Depressed, atrophic scars | Overall skin quality and fine lines | Acne scars and texture (energy-based) |
| Sessions | Usually a course of several | Usually about 3–4 | Usually a course |
| Downtime | Little; small bumps possible | Little; small bumps possible | Redness and swelling, varies by device |
Neither is “better” — they work differently and suit different goals. The right choice is decided after we assess your skin.
Safety & considerations
Possible reactions
- Small raised bumps at the injection sites, usually settling within about 1–2 days
- Temporary redness, mild swelling or a flushed feeling
- Tenderness in the treated area for a short time
- Occasionally minor bruising at injection points
When to take extra care
- Pregnancy or breastfeeding — let us know at consultation
- Active skin infection, inflammation or open lesions in the treatment area
- Known allergy or hypersensitivity, including to fish or salmon-derived products
- A history of keloid or difficulty with wound healing
- Recent injectables, resurfacing or energy treatments in the area — tell your doctor so timing can be planned
Rejuran S is used to help improve the appearance of depressed scars over a course, not to remove them entirely; suitability is confirmed during consultation. Effects develop gradually and vary by individual, and side effects may occur.

Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Potenza (microneedling RF)
Energy-based scar treatments remodel tissue in a different way and are sometimes planned in sequence with Rejuran S as part of a broader scar plan. Sequencing is decided by your doctor.
+Subcision
For tethered depressed scars, releasing the base is a separate step that a booster does not do — considered where appropriate at consultation.
+Rejuran Healer
Around treated scars, an overall polynucleotide booster such as Rejuran Healer may be planned so texture is addressed more evenly across the face.
