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 (PDRN) injectable derived from salmon DNA, engineered for ultra-thin periorbital skin to repair dark circles, fine lines, and crepey texture without Tyndall risk. RE:BERRY Incheon Airport offers Rejuran 2cc from ₩220,000 ($160 USD), 50-70% less than US/Japan pricing.
The under-eye area has the thinnest skin on the entire body — 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.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | Small papules at injection sites visible. Mild periorbital swelling normal. The polynucleotide begins integrating into the dermal matrix. |
| Day 3-5 | Papules flatten completely. Swelling resolves. Initial hydration improvement noticeable — eye area appears less dry and dehydrated. |
| Week 2-3 | A2A receptor activation triggers fibroblast proliferation. Anti-inflammatory effects reduce vascular dark circle appearance. Fine lines begin to soften. |
| Month 1-2 | New collagen type I and III synthesis measurable. Dermal thickness increases. Skin elasticity improves significantly. Dark circles visibly lighter. |
| Month 3 (after 3 sessions) | Peak improvement: dermal thickness increased 11-15%, elasticity improved 20-25%, TEWL reduced. Under-eye area appears plumper, brighter, and smoother. |
| Month 6-12 | Effects sustained 6-12 months depending on skin condition and lifestyle. Single maintenance session recommended every 6 months for optimal results. |

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.
