Rejuran i Under-Eye Dark Circle & Hollow Treatment Near Incheon Airport
Rejuran i (Eye Rejuran) is a polynucleotide-based injectable specifically formulated for the ultra-thin periorbital skin. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun uses Rejuran i to treat dark circles, under-eye hollows, crepey texture, and fine lines without the risks of traditional under-eye fillers. Rejuran 2cc starts from ₩220,000. Walk-in from the airport, walk out with brighter eyes.
What Is Rejuran i and How Does It Treat Under-Eye Dark Circles?
Rejuran i is a polynucleotide (PN/PDRN) injectable derived from salmon DNA fragments, specifically engineered for the ultra-delicate periorbital skin. Unlike hyaluronic acid fillers that add volume, Rejuran i works at the cellular level by activating the A2A adenosine receptor in dermal fibroblasts, triggering DNA repair, anti-inflammatory cascades, and new collagen synthesis. This makes it uniquely suited for treating dark circles caused by skin thinning, vascular-type dark circles from capillary fragility, fine lines, and crepey texture around the eyes. At RE:BERRY Incheon Airport, Rejuran 2cc is available from ₩220,000 (excludes VAT).
The under-eye area has the thinnest skin on the entire body — approximately 0.5mm thick compared to 2mm on the cheeks. This thinness is why dark circles, hollows, and fine lines develop so prominently and early. Traditional hyaluronic acid fillers carry risks in this area: Tyndall effect (bluish discoloration), migration, and lumpiness. Rejuran i avoids these problems entirely because it does not add volume through mechanical filling. Instead, the polynucleotide chains (molecular weight 50-300 kDa) integrate into the dermal matrix and serve as biological scaffolds that promote tissue regeneration from within. Clinical studies demonstrate that Rejuran PN injections increase dermal thickness by 11-15% after 3 sessions, improve skin elasticity by 20-25%, and significantly reduce transepidermal water loss (TEWL) in the periorbital zone. The improvement in dark circles is particularly notable for patients with constitutional (genetic) and post-inflammatory hyperpigmentation subtypes, as Rejuran’s anti-inflammatory properties (PDRN activates A2A receptors, reducing TNF-alpha and IL-6 expression) address the root cause rather than masking it. For patients seeking complementary under-eye treatments, Rejuran + Juvelook skin booster combinations offer both regeneration and collagen stimulation. For volume-based under-eye hollows, cheek fillers can restore mid-face volume that indirectly lifts the tear trough. Dr. Cho Sung-Jun also recommends combining Rejuran i with glass skin laser toning for comprehensive periorbital rejuvenation including pigmentation reduction.

How Rejuran i Eye Treatment Works at RE:BERRY
A precise four-step protocol designed specifically for the delicate periorbital area.
Under-Eye Assessment & Skin Analysis
Dr. Cho Sung-Jun examines the periorbital area under magnification and cross-polarized light to classify dark circle type: vascular (bluish, capillary-related), pigmented (brownish, melanin-based), structural (hollowing/tear trough), or mixed. Skin thickness, elasticity, and hydration levels are measured using a dermoscope. Based on assessment, Dr. Cho determines optimal injection depth (0.5-1.5mm), volume (typically 0.5-1cc per under-eye), and whether Rejuran i should be combined with other modalities for your specific dark circle subtype.
Topical Anesthesia & Preparation
A specialized eye-safe topical anesthetic cream (lidocaine-based, ophthalmologist-approved formulation) is applied to the under-eye area for 15-20 minutes. The area is then cleansed with a gentle antiseptic solution. Rejuran i is prepared at room temperature for optimal viscosity. Dr. Cho marks injection points using a sterile marker — typically 8-12 micro-injection points per side following the infraorbital contour. A vibration anesthesia device may be used for patients with heightened sensitivity in the eye zone.
Micro-Injection into Periorbital Dermis
Using a 32-gauge ultra-fine needle or 27-gauge blunt cannula (depending on the treatment zone), Dr. Cho delivers Rejuran i into the papillary and reticular dermis at precisely controlled depths. The serial puncture technique creates micro-deposits of polynucleotide in a grid pattern, ensuring uniform coverage across the under-eye zone. For the inner corner (medial canthus) near the tear trough, a fanning cannula technique is used to minimize bruising risk. The entire injection process takes 15-20 minutes for both eyes. Small papules at injection sites are normal and indicate correct dermal placement.
Recovery & LED Therapy
Immediately after injection, cryotherapy (cold air device) is applied to reduce swelling and minimize bruising risk. LED photobiomodulation (630nm red + 830nm near-infrared) accelerates the polynucleotide integration and provides anti-inflammatory benefits. Small papules at injection sites flatten within 24-48 hours. Most patients experience mild swelling for 1-2 days. You can fly the same day — Rejuran i has zero downtime restrictions for air travel. Mineral SPF and barrier-repair serum are provided. Makeup can be applied the next morning. Optimal results require 3-4 sessions at 2-4 week intervals.
What to Expect from Rejuran i Eye Treatment
- Cellular-Level Eye Skin Repair: Rejuran i’s polynucleotides activate DNA repair mechanisms in periorbital fibroblasts, increasing dermal thickness by 11-15% after a treatment course — addressing the root cause of dark circles from thin skin.
- No Tyndall Effect Risk: Unlike HA fillers that can cause bluish discoloration (Tyndall effect) when placed superficially under thin eye skin, Rejuran i contains no hyaluronic acid and cannot produce this complication.
- Anti-Inflammatory Dark Circle Reduction: PDRN activates A2A adenosine receptors, suppressing TNF-alpha and IL-6 pro-inflammatory cytokines. This directly reduces vascular and post-inflammatory dark circle types at the molecular level.
- Airport-Adjacent Convenience: RE:BERRY Incheon Airport is minutes from Incheon International Airport Terminal 1. Get Rejuran i during a layover or before your flight. Zero downtime for air travel.
- Safe for Ultra-Thin Skin: Rejuran i is specifically formulated for injection into skin as thin as 0.5mm. The low molecular weight polynucleotide formulation ensures even distribution without lump formation in the delicate periorbital zone.

The Science Behind Rejuran i Polynucleotide Eye Treatment
Peer-reviewed evidence supporting polynucleotide therapy for periorbital rejuvenation.
Polynucleotide Mechanism of Action in Periorbital Skin
Rejuran i contains highly purified polynucleotide (PN) chains derived from salmon DNA (Oncorhynchus keta) with a molecular weight of 50-300 kDa. These PN chains function as biological scaffolds that integrate into the dermal extracellular matrix. Upon injection, PN fragments bind to the A2A purinergic receptor on fibroblast cell membranes, triggering intracellular cyclic AMP (cAMP) production. Elevated cAMP activates protein kinase A (PKA), which phosphorylates CREB (cAMP response element-binding protein), ultimately upregulating genes responsible for collagen type I and III synthesis, elastin production, and glycosaminoglycan (GAG) accumulation in the dermis.
Anti-Inflammatory Properties for Vascular Dark Circles
A significant proportion of under-eye dark circles are vascular in origin — caused by increased capillary permeability, hemosiderin deposition from red blood cell extravasation, and chronic low-grade periorbital inflammation. PDRN (polydeoxyribonucleotide), the active component in Rejuran i, exerts potent anti-inflammatory effects through A2A receptor activation. This pathway suppresses nuclear factor-kappa B (NF-kappaB) signaling, reducing production of pro-inflammatory cytokines TNF-alpha, IL-1beta, and IL-6. Clinical histological studies show reduced perivascular inflammation and improved capillary wall integrity after 3 sessions of periorbital PDRN injections, directly addressing vascular-type dark circles.
Clinical Evidence for Dermal Thickening
A prospective study published in the Journal of Cosmetic Dermatology evaluated PN injection therapy in 45 patients with periorbital aging. After 3 biweekly sessions, high-frequency ultrasound measurements demonstrated a mean dermal thickness increase of 12.3% (p<0.001) in the infraorbital zone. Corneometry readings showed a 28% improvement in skin hydration, and Cutometry measurements revealed a 22% increase in skin elasticity (R2 parameter). Patient satisfaction surveys reported significant improvement in dark circle severity, fine line depth, and overall eye area appearance, with 89% of patients rating results as good or excellent.
Rejuran i’s safety profile in the periorbital zone is well-established. A systematic review analyzing 12 studies with 847 total patients found no cases of Tyndall effect, granuloma formation, or vascular occlusion — complications that are reported with HA fillers in the tear trough area. The most common side effects were injection-site papules (100%, resolving in 24-72 hours) and mild ecchymosis (15%, resolving in 5-7 days). No serious adverse events were reported.

Rejuran i Eye Treatment FAQ
Everything you need to know about Rejuran i (Eye Rejuran) at RE:BERRY Incheon Airport.
Rejuran 2cc is ₩220,000 (regular ₩430,000) at RE:BERRY Incheon Airport as an April 2026 promotion. The Eye Repair Package (Eye Oligio 200 shots + Eye Rejuran 2cc) is ₩840,000. All prices exclude VAT. Non-covered medical service.
Rejuran i is a formulation of Rejuran specifically optimized for the periorbital (eye) area. It uses the same salmon-derived polynucleotide technology but with adjusted molecular weight distribution and concentration for the ultra-thin under-eye skin (0.5mm). The injection technique also differs — shallower depth, finer needle gauge, and lower volume per injection point.
Yes. Rejuran i has zero downtime restrictions for air travel. Small injection papules resolve within 24-48 hours. Mild swelling is normal for 1-2 days. You can fly immediately after treatment. RE:BERRY Incheon Airport is minutes from Incheon International Airport Terminal 1.
For optimal results, 3-4 sessions at 2-4 week intervals are recommended. Each session builds on the previous one as polynucleotide chains stimulate cumulative collagen production and dermal thickening. After the initial course, a single maintenance session every 6-12 months sustains results.
For dark circles caused by thin skin, vascular issues, or pigmentation, Rejuran i is often superior because it addresses the root cause (skin thinning, inflammation) rather than masking it with volume. HA fillers are better for structural hollows (tear trough deformity). Many patients benefit from a combination approach. Unlike fillers, Rejuran i carries zero risk of Tyndall effect (blue discoloration).
Topical anesthesia is applied for 15-20 minutes before treatment. Most patients describe the sensation as a series of tiny pinches. The 32-gauge needle is thinner than a human hair. Injection papules (small bumps at injection sites) are normal and indicate correct dermal placement — they flatten within 24-48 hours. Bruising occurs in approximately 15% of cases and resolves within 5-7 days.
Rejuran i is effective for vascular dark circles (bluish, from capillary fragility — reduced through anti-inflammatory A2A receptor activation), pigmented dark circles (brownish, from melanin — improved through skin thickening), thin-skin dark circles (showing underlying muscle/vessels — addressed by increasing dermal thickness 11-15%), and mixed-type dark circles (most common). Structural hollows from fat pad loss may require additional filler treatment.
Yes. At RE:BERRY Incheon Airport, popular combinations include Rejuran i + Eye Oligio (RF tightening, ₩840,000 package), Rejuran i + laser toning (pigmentation reduction), and Rejuran i + under-eye filler (for patients needing both regeneration and volume). Treatments can be spaced 2-4 weeks apart or performed same-day depending on the combination.
After a full course of 3-4 sessions, Rejuran i results typically last 6-12 months. The collagen and elastin produced by stimulated fibroblasts is your own tissue and persists until normal aging processes gradually break it down. Maintenance sessions every 6 months extend results indefinitely.
Rejuran i has an excellent safety profile. A systematic review of 847 patients found zero cases of Tyndall effect, granuloma, or vascular occlusion. Expected side effects: injection papules (100%, resolve 24-72h), mild swelling (80%, resolve 1-2 days), minor bruising (15%, resolve 5-7 days). Rejuran is MFDS-approved and uses biocompatible salmon-derived polynucleotides with decades of clinical use.
Rejuran i is not recommended for patients with active infections or inflammation in the eye area, known allergy to salmon or fish-derived products, autoimmune conditions affecting the periorbital area, pregnant or breastfeeding women (as a precaution), or patients on active blood thinners (higher bruising risk — consult physician). For patients with severe structural tear trough deformity, filler may be more appropriate.
Rejuran i uses polynucleotides (DNA repair + anti-inflammatory) while Juvelook uses PDLLA + hyaluronic acid (collagen scaffolding + hydration). Rejuran i is specifically formulated for the ultra-thin periorbital skin and has a stronger evidence base for dark circle treatment. Juvelook is not typically injected directly into the under-eye area. For comprehensive skin rejuvenation, Juvelook can be used on the mid-face while Rejuran i targets the periorbital zone.
