Quick answer: Rejuran Eye is a polynucleotide booster formulated for the delicate under-eye area. It improves thin, crepey skin and fine lines and can make shadowing from thin skin less visible, but it does not fill deep hollows. Two to three sessions spaced about 4 weeks apart are typical, and minor bumps or bruising may last a few days.
What Rejuran Eye can help
- Crepey, wrinkled under-eye skin.
- Fine lines around the eyes.
- Dark circles caused by thin, translucent skin.
- Dull, tired-looking eye area.
What it cannot do
It does not add volume to deep tear troughs or remove fat bags. Hollows may need carefully placed filler, and prominent fat bags may need surgery.
How it differs from regular Rejuran Healer
The eye formula uses a smaller particle size and a finer injection technique suited to thin skin, reducing lumpiness and discomfort compared with the standard product.
The procedure
- Numbing cream for about 30 minutes.
- Fine injections along the lower lid and crow's feet area.
- Small bumps that settle over 1 to 3 days.
Results
Skin often looks smoother within a couple of weeks, with more visible improvement after the second or third session.
Side effects
- Bruising, which is more common around the eyes.
- Mild swelling, often worse in the morning.
- Temporary bumps.
Rejuran Eye vs under-eye filler
- Rejuran Eye: improves skin quality; low risk of puffiness.
- Filler: fills hollows for an immediate change but needs advanced technique to avoid lumps or puffiness.
Understanding the causes of dark circles
Dark circles can come from several sources, and the right treatment depends on which applies to you. Thin skin lets underlying blood vessels and muscle show through, giving a bluish or purple tone. Hollows or a deep tear trough create shadows. Pigmentation produces a brown tone, common in people with darker skin or allergies. Puffiness or fat bags cast shadows below them. Rejuran Eye mainly helps thin, crepey skin, so a doctor's assessment matters before treatment.
How the injection technique differs
The under-eye skin is among the thinnest on the body, so Rejuran Eye is injected with very fine needles in tiny amounts, usually avoiding the area directly over large vessels. Some clinics use a blunt cannula to reduce bruising. Because of the delicate area, treatment by a doctor experienced in periorbital injections is especially important.
Price and course
Rejuran products in Busan typically cost about ₩150,000 to ₩400,000 per session in 2026; eye-specific treatments are often priced separately. Most patients plan two to three sessions spaced about four weeks apart.
Combining with other eye-area treatments
- Crow's feet Botox for expression lines.
- Laser toning for pigment-related darkness.
- Small amounts of filler for true hollows.
- Gentle RF eye treatments for laxity.
Aftercare for the eye area
- Avoid rubbing your eyes and wearing contact lenses for the rest of the day if advised.
- Sleep with your head slightly elevated the first night to limit swelling.
- Skip eye makeup until the next day.
- Use cool compresses for bruising.
Planning Rejuran Eye during a trip to Busan
Bruising is more common around the eyes and can last several days, so allow time before photos or flights. Two to three sessions give the best result. Most international visitors stay in Seomyeon, the city's largest clinic district and a central subway hub, or in Haeundae and Centum City near the beach. Seomyeon is about 35 minutes from Gimhae International Airport by light rail and subway and about 12 minutes from Busan Station (KTX) on Line 1, while Haeundae is about 30 to 40 minutes further east on Line 2. Book your consultation before you arrive, share your travel dates with the clinic, and leave at least one buffer day before your flight in case you want a follow-up check.
Questions to ask at your consultation
- What is causing my dark circles?
- Will you use a needle or cannula around my eyes?
- Would filler or laser help more than Rejuran Eye in my case?
- Is the clinic registered with HIRA, and who will perform the treatment?
- Does the written quote include VAT, numbing cream and any follow-up visit?
- How can I contact the clinic with questions after I return home?
How to choose a clinic for Rejuran Eye in Busan
Busan has roughly 1,000 registered clinics across dermatology, plastic surgery and other specialties, so it is worth comparing a few before you book. Start by checking that the clinic is listed with Korea's Health Insurance Review and Assessment Service (HIRA), then look at the doctor's specialty and experience with Rejuran Eye. In Korea, a clinic name that includes "Dermatology" (피부과) or "Plastic Surgery" (성형외과) indicates the director is a board-certified specialist in that field. During consultation, a good clinic will explain realistic results, side effects and alternatives, give you a written quote, and never pressure you into same-day packages. Read recent patient reviews with a critical eye, and favour clinics that provide English aftercare instructions and a clear way to contact them after you leave Korea.
