Rejuran I for the Eye Areain Gangnam, Seoul
Rejuran I is a polynucleotide (PN) skin booster formulated with a lower viscosity for the thin, delicate skin under and around the eyes. At QD Clinic in Gangnam, Seoul, it is used to help improve fine lines, crepey texture and elasticity in the periorbital area. A session usually takes about 20–30 minutes including numbing. (Results vary by individual.)
Who it’s for
- Fine lines and crepey texture under and around the eyes
- Thin skin around the eyes that looks tired or dull
- Those who want to support skin quality around the eyes rather than add volume
- People treating the eye area alongside a full-face booster plan
Whether the under-eye is suitable for Rejuran I, or another approach fits better, is confirmed during consultation.
How it works
Rejuran I is formulated with a lower viscosity than the standard formula, made for the thin, delicate skin around the eyes. Polynucleotides (PN) from salmon DNA are placed with fine microinjections under and around the eyes to support the skin’s own repair environment, helping improve fine lines, crepey texture and elasticity over a series of sessions. It focuses on skin quality in the eye area rather than filling volume. (“I” refers to the eye-area formula.)
THE MECHANISM, STEP BY STEP
01Lower-viscosity PN for thin skin
Rejuran I uses a lower-viscosity polynucleotide (PN) formula, made to sit comfortably in the thin, delicate skin under and around the eyes.
02Supporting the skin’s own repair
PN is thought to support the repair environment of the skin around the eyes rather than adding volume, helping with fine lines and crepey texture.
03Placed with fine microinjections
Very fine microinjections distribute the PN evenly across the under-eye and outer-eye area at a shallow depth.
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
- Under-eye
- Thin, crepey skin below the eyes.
- Outer eye (crow’s-feet area)
- Fine lines at the outer corners of the eyes.
- Around the eyes
- The wider area around the eyes, decided at consultation.
What the procedure is like
- 1Consultation and assessment of the eye area
- 2Cleansing and numbing cream
- 3Fine microinjections under and around the eyes
- 4Cooling, soothing and aftercare guidance
Time: A session takes about 20–30 minutes, including numbing time.
Recovery & aftercare
- Little downtime; small raised bumps under the eyes may appear and can take up to about a day to settle in this delicate area.
- Temporary redness, mild swelling, tenderness or minor bruising may occur around the eyes.
- Avoid rubbing the area, 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 fine microinjections around the eyes. Small raised bumps at the injection sites are common, with mild redness or swelling.
DAY 1-2 Bumps settling
The small bumps usually settle; in the delicate under-eye area this can take up to about a day or a little longer. Minor bruising, if any, starts to fade.
WEEK 1-3 Between sessions
The skin around the eyes may begin to look a little smoother. Sessions are usually spaced 2–4 weeks apart.
1-3 MONTHS Skin-quality change
Over the course and the following weeks, many people notice finer texture and improved firmness around the eyes. (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 about 3–4 sessions spaced roughly 2–4 weeks apart, with changes developing gradually over the following weeks. Maintenance is considered after a period decided at consultation. (Results vary by individual.)
How it compares
These options all address the under-eye, but they use different materials and aims, so the right one depends on whether you want skin-quality support or volume.
| Comparison | Rejuran I | Juvelook I | Under-eye filler |
|---|---|---|---|
| Main agent | Polynucleotides (from salmon DNA) | PDLLA microparticles + HA | Hyaluronic-acid filler |
| How it works | Supports the skin’s own repair | Prompts gradual collagen renewal, with hydration | Adds volume to fill the area |
| Often chosen for | Fine lines, crepey under-eye texture | Under-eye skin quality with subtle plumping | Under-eye hollowing or volume loss |
| Sessions | Usually a course of a few | Usually a short course | Often a single placement, refined as needed |
| Downtime | Little; small bumps possible | Little; small papules possible | Little; swelling or bruising 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, which can take up to about a day to settle in the delicate under-eye area
- Temporary redness, mild swelling or a flushed feeling around the eyes
- Tenderness in the eye 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 around the eyes
- Known allergy or hypersensitivity, including to fish or salmon-derived products
- A history of keloid or difficulty with wound healing
- Recent injectables or energy treatments around the eyes — tell your doctor so timing can be planned
Whether the under-eye area is suitable for Rejuran I is confirmed during consultation, and it is not suitable for everyone. Effects develop gradually over a series of sessions and vary by individual, and side effects may occur.

Frequently asked questions
Rejuran I is made for the eye area. Its lower-viscosity polynucleotide formula is used to help improve fine lines, crepey texture and elasticity under and around the eyes. (Results vary by individual.)
Filler adds volume, while Rejuran I supports skin quality and texture in the thin skin around the eyes. Which approach fits your under-eye concern is decided at consultation.
It may help with fine lines and crepey texture that can make the under-eye look tired. Dark circles have several causes, so suitability is assessed at consultation. (Results vary by individual.)
Small bumps at the injection points are common and, in the delicate under-eye area, can take up to about a day to settle.
Many people have about 3–4 sessions spaced 2–4 weeks apart. Your plan is decided at consultation. (Results vary by individual.)
Yes. Our doctors consult in English directly, and 中文 / 日本語 can be arranged in advance. Tell us your language on WhatsApp before your visit.
Often considered together
Treatments that are sometimes planned alongside this one, decided at consultation.
+Botulinum toxin
For crow’s-feet lines from muscle movement at the outer eye, toxin is sometimes planned alongside eye-area skin-quality treatment for a balanced result.
+Under-eye filler
Where the concern is volume or hollowing rather than skin quality, filler addresses something a booster does not — the two can be discussed together at consultation.
+Rejuran Healer
The eye area is often treated within a wider skin-quality plan; a full-face polynucleotide booster such as Rejuran Healer may be planned alongside.
