Rejuran Skin Boosterin Gangnam, Seoul
Rejuran is an injectable skin booster that uses polynucleotides (PN) purified from salmon DNA to support the skin’s own repair and improve texture, fine lines and elasticity. At QD Clinic in Gangnam, Seoul, we offer the Rejuran range — Healer, HB, I and S — and choose the formula and areas after assessing your skin. A session usually takes about 20–40 minutes including numbing. (Results vary by individual.)
Who it’s for
- Dull skin, fine lines or early loss of elasticity
- Those who want to improve overall skin quality rather than add volume
- Dry or sensitive skin looking for a hydration and comfort option (HB)
- Concerns around the eyes or depressed scars (I and S)
Which Rejuran formula suits you is confirmed during consultation.
How it works
Rejuran delivers polynucleotides — long chains of nucleotides purified from salmon DNA — into the skin with fine microinjections. PN is thought to support the skin’s own repair environment, helping to improve hydration, elasticity and fine texture over a series of sessions. The range is tailored to different needs: Healer for overall skin quality, HB with added hyaluronic acid for hydration and comfort, I for the delicate eye area, and S for depressed scars.
THE MECHANISM, STEP BY STEP
01Polynucleotides from salmon DNA
Rejuran delivers polynucleotides (PN) — long chains of nucleotides purified from salmon DNA — into the skin with fine microinjections.
02Supporting the skin’s repair environment
PN is thought to support the skin’s own repair environment rather than adding volume, helping the skin work on hydration, elasticity and fine texture.
03A range for different needs
The formula is tailored: Healer for overall quality, HB with hyaluronic acid for hydration, I for the eye area, and S for depressed scars.
04Built over a series
Because it works with the skin’s own processes, changes develop across a series of sessions rather than at once. (Results vary by individual.)
Treatment areas
- Full face
- Overall skin quality, fine lines and elasticity.
- Under-eye
- Thin skin and fine lines around the eyes (Rejuran I).
- Neck & hands
- Crepey skin on the neck and backs of the hands.
- Depressed scars
- Atrophic acne or sunken scars (Rejuran S).
What the procedure is like
- 1Consultation and skin assessment
- 2Cleansing and numbing cream
- 3Microinjections across the treatment area
- 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 are common 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 microinjections across the area. 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; under-eye areas can take a little longer. Minor bruising, if any, starts to fade.
WEEK 1-3 Between sessions
Skin may begin to look a little smoother or brighter. Sessions are usually spaced 2–4 weeks apart.
1-3 MONTHS Skin-quality change
Over the course and the following weeks, many people notice smoother texture and improved elasticity as collagen remodels. (Results vary by individual.)
AFTER THE COURSE Review & maintenance
Your doctor reviews the outcome and discusses maintenance timing based on your skin.
Sessions & results
A typical plan is a course of about 3–4 sessions spaced roughly 2–4 weeks apart, with skin looking smoother and brighter gradually over the following weeks and fuller collagen remodeling over a few months. Maintenance is considered after a period decided at consultation. (Results vary by individual.)
How it compares
These injectable skin boosters all support skin quality, but they use different materials and work in different ways, so they suit different goals.
| Comparison | Rejuran | Juvelook | Re2O |
|---|---|---|---|
| Main agent | Polynucleotides (from salmon DNA) | PDLLA microparticles + HA | ECM components (collagen, elastin, HA) |
| How it works | Supports the skin’s own repair | Prompts gradual collagen renewal | Supplies ready-made matrix as a scaffold |
| Often chosen for | Overall skin quality, fine lines | Texture, glow and subtle structure | Structural support, thin or crepey skin |
| Sessions | Usually a course of a few sessions | Usually a short course | Usually a short course |
| Downtime | Little; small bumps possible | Little; small papules possible | Little; small bumps possible |
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

Healer targets overall skin quality, HB adds hyaluronic acid for hydration and comfort, I is made for the eye area, and S is made for depressed scars. The right one is chosen at consultation.
A numbing cream is applied beforehand, and the HB formula also contains lidocaine to help comfort. Some brief stinging may still be felt. (Results vary by individual.)
Many people have about 3–4 sessions spaced 2–4 weeks apart, then maintenance later. Your plan is decided at consultation. (Results vary by individual.)
Small raised bumps at the injection sites are common and usually settle within 1–2 days; under-eye areas can take a little longer.
They work differently — Rejuran uses polynucleotides to support repair, while Juvelook uses PDLLA to prompt collagen. The right choice depends on your skin, decided at consultation.

Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Ultrasound or RF lifting
Energy-based lifting addresses laxity and deeper support, which boosters do not target — sometimes planned together for skin quality plus firmness. Sequencing is decided by your doctor.
+Botulinum toxin
For dynamic lines from muscle movement (forehead, frown, crow’s feet), often planned alongside skin-quality treatments for a balanced result.
+Hyaluronic-acid filler
For areas where volume has softened, filler adds structure that a booster does not — planned together where appropriate at consultation.
