Rejuran IUnder-eye & eye area · in Gangnam, Seoul
Rejuran I is a polynucleotide (PN) product used for eye-area fine lines and skin condition. Its purpose differs from filling a deep trough. The product instructions and examination guide the area and any repeat sessions. 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 in Gangnam, Seoul, South Korea, your goals and skin assessment guide the product, area and recovery plan.


Who it’s for
- We first check whether the fine lines and texture you notice up close are your main concern. Dark circles may combine hollows, pigment and visible vessels, so improving texture alone cannot address every cause.
- Under-eye darkness may involve hollows, protruding fat, pigmentation or skin quality. Each product’s approved use, the condition of your eyelids and previous treatments guide suitability. Whether each product is injected directly under the eyes or used on the surrounding area is decided at the examination.

Sessions & results

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.

|---|---|---|---|
| Selection | Rejuran I is a polynucleotide (PN) product used for eye-area fine lines and skin condition. Its purpose differs from filling a deep trough. The product instructions and examination guide the area and any repeat sessions. 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. | Juvelook I is a treatment using PDLLA and hyaluronic acid (HA) for eye-area fine lines and texture. We confirm the exact product and formulation, its approved scope and your skin thickness before choosing the area. Deep hollows and protruding fat are assessed separately, and fullness on the day of treatment is not taken as a collagen effect. | Filler may soften shadows caused by hollows. It does not remove pigment or protruding fat, and if your under-eyes often swell or your skin is very thin, swelling, visible product and unevenness are considered first. Choose the formulation and area, not the brand alone. |
They work differently and suit different goals. The right choice is decided after examination.
Safety & considerations

When to take extra care
- Disclose pregnancy or breastfeeding, allergies, immune conditions, medicines, previous fillers and threads.
- 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.
