Rejuran I
qd rejuran i
Rejuran I is a polynucleotide (PN) product used for fine lines and skin condition around the eyes. Its purpose is distinct from filler that fills hollow grooves, and the treatment area and whether to repeat are decided according to the product instructions and the condition of the eye area. On thin eye-area skin even small injection marks and bruises can be noticeable, so previous reactions to PN treatment and any allergies are checked in advance. At QD Clinic, your goals and skin assessment guide the product, area and recovery plan.
Rejuran I is available at QD Clinic in Gangnam, Seoul, Korea.


is this for me
Who it’s for
Even if none of these describes you, we will look again at the consultation.
- We check whether fine lines and skin texture that bother you up close are the main concern. Dark circles can have mixed causes such as hollowing, pigmentation and visible blood vessels, so skin-texture treatment alone does not improve them all.
- Under-eye darkness may involve hollows, protruding fat, pigmentation or skin quality. Suitability is judged after checking the product’s approved use, the condition of your eyelids and previous treatments. Whether each product is injected directly under the eyes or used on the surrounding area is decided at the examination.
start with your concern
Before you pick a treatment name, start with the cause of your concern.
Even a treatment with the same name takes on a different role and scope depending on your current structure, the change you want, what you have had before and the recovery time you have.

the principle
How it works
Rejuran I
Rejuran I is a polynucleotide (PN) product used for fine lines and skin condition around the eyes. Its purpose is distinct from filler that fills hollow grooves, and the treatment area and whether to repeat are decided according to the product instructions and the condition of the eye area. On thin eye-area skin even small injection marks and bruises can be noticeable, so previous reactions to PN treatment and any allergies are checked in advance.

How it works
Assessing the change
With PN treatment, fine lines and skin condition are reviewed after injection bumps settle. Rather than recommending a fixed number of sessions up front, we decide whether and how often to repeat from your skin condition, the specific product instructions and your response to the first treatment. Allow recovery time before an important event.
the qd standard
The same treatment, never the same plan.
Rather than a fashionable name or a fixed package, we weigh the structure found at examination, safety, recovery and the limits within one plan.
- DIAGNOSIS FIRST
Cause before name
We first separate out the tissue and the function behind your concern.
- LESS, PRECISE
Only as much as needed
Rather than an excessive change, we plan the smallest scope with a clear role.
- HONEST LIMIT
The limits, explained too
We explain the change you can expect, the alternatives, individual differences and the risks.
personal plan
From consultation to follow-up, planned as one flow.

Start with the concern
Before your consultation, please note your usual swelling and dry eyes, any previous filler or surgery, and the medicines you take. If you have an important event or departure date, we plan recovery time and how follow-up will be checked as well.
Understand your product
We check whether fine lines and skin texture that bother you up close are the main concern. Dark circles can have mixed causes such as hollowing, pigmentation and visible blood vessels, so skin-texture treatment alone does not improve them all.
Plan through recovery
After appropriate comfort measures and cleansing, the doctor treats the agreed areas.
What the procedure is like
- Before your consultation, please note your usual swelling and dry eyes, any previous filler or surgery, and the medicines you take. If you have an important event or departure date, we plan recovery time and how follow-up will be checked as well.

- Receive aftercare and contact instructions, and arrange an appropriate review.
Appointment length depends on consultation, numbing and treatment extent. Tell us your available time and important plans when booking.
Please read this before treatment
- On thin skin, even small injection marks and bruises can be noticeable. Leave some room for recovery, and if redness, swelling or pain worsens or lasts a long time, please contact the clinic. Please also tell us in advance about any allergies or reactions to previous PN treatments.
Safety & considerations
Possible reactions
- Infection, persistent nodules, unevenness, inflammation or allergic reactions can occur. Injections carry rare but serious risks including vascular injury or blockage and tissue damage.
Before treatment
- Tell us about pregnancy or breastfeeding, allergies, immune conditions, medicines, and previous fillers, threads or other procedures.
- Active inflammation or infection at the site needs assessment before treatment is scheduled.
Worsening pain, pale or mottled skin, visual symptoms or breathing difficulty need urgent medical attention. Outcomes and duration vary; a specific result is not guaranteed.
what to expect
What to expect over time
A general guide to how the days and months after treatment usually unfold. Results vary by individual.
Immediately
Injection marks, redness, swelling, bruising, tenderness or small bumps can occur and usually settle; how quickly varies from person to person.
Early recovery
Monitor bruising, swelling and injection marks. Contact the clinic if symptoms worsen or persist.
Sessions & results
Once the small bumps after injections around the eyes have subsided, we compare fine lines and skin texture. The interval used for other lines such as Rejuran Healer is not applied as is; the next treatment is timed according to how the eye area recovers and the product information. If concerns that are not the goal of Rejuran I, such as a deep tear trough, remain, other methods are compared rather than increasing the number of sessions.

For this treatment, QD Clinic in Gangnam, Seoul starts by looking at this: “Rejuran I is a polynucleotide (PN) product used for fine lines and skin condition around the eyes”.
