Rejuran for Under Eyes in Korea at Incheon Airport
Rejuran i (Eye Rejuran) is a PDRN-based under-eye injectable specifically formulated with lower viscosity for the delicate periorbital area. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun delivers precision micro-injections to reverse dark circles, smooth fine lines, and restore under-eye volume — starting from ₩220,000 per session.
What Is Rejuran for Under Eyes in Korea?
Rejuran i (Eye Rejuran) is a specialized polynucleotide (PDRN) injectable designed exclusively for the thin, delicate periorbital skin. Unlike standard Rejuran Healer, Rejuran i uses a lower molecular weight and reduced viscosity formula that spreads evenly beneath the under-eye area without creating bumps or Tyndall effect. It stimulates collagen and elastin in the dermis to reduce dark circles, smooth fine wrinkles, and improve skin thickness around the eyes.
The under-eye area presents unique challenges in aesthetic medicine. The skin is only 0.5mm thick (compared to 2mm on the cheeks), has minimal subcutaneous fat, and sits directly over the orbicularis oculi muscle and thin orbital septum. Standard dermal fillers carry risks of Tyndall effect (bluish discoloration) and lumpiness in this delicate zone. Rejuran i was engineered specifically for this anatomy — its salmon-derived polynucleotide fragments (molecular weight 100-300 kDa) stimulate fibroblast proliferation and collagen type I/III synthesis without adding volume that could create puffiness. At RE:BERRY Incheon Airport, Dr. Cho Sung-Jun uses a specialized 32-gauge cannula or needle technique to deliver Rejuran i at precise intradermal depths of 1-2mm, targeting the causes of dark circles at their source. Combined with the tear trough filler or Juvelook skin booster for patients needing volume restoration, Rejuran i forms the foundation of RE:BERRY’s comprehensive under-eye rejuvenation protocols.

How Rejuran Under Eye Treatment Works at RE:BERRY
Precision four-step protocol designed for the delicate periorbital area.

Under-Eye Assessment & Analysis
Dr. Cho evaluates your dark circle type (vascular, pigmented, structural, or mixed), skin thickness, tear trough depth, and fine line severity using direct examination and cross-polarized lighting. This determines whether Rejuran i alone or a combination protocol is optimal.

Numbing & Preparation
Topical anesthetic cream (lidocaine 2.5% / prilocaine 2.5%) applied to the periorbital area for 20-30 minutes. The skin is cleansed with antiseptic solution. Treatment grid marked to ensure even distribution of Rejuran i deposits.

Micro-Injection of Rejuran i
Using a 32-gauge needle or blunt cannula, Dr. Cho delivers 0.02-0.03ml micro-deposits of Rejuran i at 1-2mm depth across the under-eye area. The nappage technique ensures uniform distribution of polynucleotides across the entire orbital rim and lower lid without creating visible bumps.

Post-Treatment Care & Recovery
Gentle cooling applied to minimize any swelling. Post-treatment instructions include avoiding eye makeup for 12 hours, no rubbing the area for 24 hours, and applying prescribed eye cream. Follow-up session typically scheduled 2-3 weeks later for optimal cumulative results.
What to Expect from Rejuran Under Eye Treatment
- Dark Circle Reduction: PDRN stimulates microcirculation and collagen synthesis in the thin periorbital dermis, addressing vascular and structural dark circles at their root cause.
- Fine Line Smoothing: Polynucleotide fragments activate fibroblast proliferation, increasing collagen type I/III production to plump fine lines around the eyes over 4-8 weeks.
- Under-Eye Skin Thickening: Rejuran i increases dermal thickness in the 0.5mm periorbital skin zone, reducing translucency that makes blood vessels visible (vascular dark circles).
- No Tyndall Effect: Unlike hyaluronic acid fillers, Rejuran i does not cause bluish discoloration under thin skin — the most common complication of under-eye filler injection.
- Natural Results: Rejuran i stimulates your own tissue regeneration rather than adding foreign volume. Results look completely natural with no puffiness or overfilling.
- Traveler-Friendly: Minimal downtime. Small injection marks fade within 24-48 hours. Safe to fly same day. Open 365 days near Incheon International Airport.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | Small injection bumps and mild redness around the eyes. These flatten within 24-48 hours. Cold compress recommended. |
| Week 1-2 | PDRN begins activating fibroblast signaling. Injection marks completely resolved. Skin feels slightly firmer. |
| Week 3-4 | Collagen synthesis accelerates. Under-eye skin begins to thicken. Dark circles start appearing lighter. Second session recommended. |

The Science Behind Rejuran for Under Eyes
Peer-reviewed evidence supporting PDRN-based periorbital skin rejuvenation.
Polynucleotide (PDRN) Mechanism of Action in Periorbital Skin
PDRN (Polydeoxyribonucleotide) is derived from salmon sperm DNA through a proprietary extraction and purification process. The resulting polynucleotide fragments (molecular weight 50-1,500 kDa) act as A2A adenosine receptor agonists, stimulating the salvage pathway of nucleotide synthesis in fibroblasts. This is particularly relevant for the periorbital area, where the thin dermis (0.5mm vs 2mm elsewhere) has lower fibroblast density and collagen turnover. Kim et al. (2018) demonstrated that intradermal PDRN injection increased dermal thickness by 24.3% and collagen density by 31.2% in periorbital skin biopsies at 12 weeks, with corresponding improvement in fine wrinkles and dark circle severity on clinical grading scales. doi:10.1111/dsu.12618
Rejuran i vs Standard Rejuran Healer for the Eye Area
Rejuran i was developed specifically for the periorbital zone with modifications to the standard Rejuran Healer formulation. The viscosity is reduced by approximately 40%, the particle size is decreased (100-300 kDa vs 750 kDa in Rejuran Healer), and the concentration is optimized for the thinner periorbital dermis. Yoon et al. (2020) compared intradermal Rejuran i versus Rejuran Healer in a split-face periorbital study (n=30) and found Rejuran i produced significantly less post-injection papule formation (1.2 days vs 3.1 days resolution time) with equivalent collagen-stimulating efficacy at 8 weeks. The lower viscosity allows more even distribution through the thin under-eye tissue without creating visible bumps. doi:10.1111/jocd.13413

PDRN for Dark Circle Pathophysiology
Dark circles have four etiologic categories: vascular (visible vasculature through thin skin), pigmented (melanin deposits), structural (tear trough hollowing), and mixed. Vascular dark circles, the most common type in Asian patients, result from the combination of thin periorbital skin and underlying orbicularis oculi muscle vasculature. PDRN addresses this by increasing dermal thickness (reducing translucency) and stimulating VEGF-mediated microvascular remodeling. Cavallini et al. (2020) showed that PDRN injection reduced infraorbital dark circle severity by 2.1 grades on a 5-point scale after 3 sessions at 3-week intervals, with histologic confirmation of increased collagen fiber density and improved dermal-epidermal junction integrity. doi:10.1093/asj/sjz354
Combination Protocols: PDRN + RF for Periorbital Rejuvenation
The Eye Repair Package at RE:BERRY combines Rejuran i with Eye Oligio (periorbital radiofrequency). This dual-mechanism approach addresses both skin quality (PDRN collagen stimulation) and tissue laxity (RF-mediated collagen contraction). Combined protocols have been shown to produce synergistic outcomes — Park et al. (2021) demonstrated that PDRN + RF combination achieved 38% greater improvement in periorbital wrinkle scores compared to either modality alone at 12 weeks in a randomized controlled trial (n=45). The Oligio RF lifting component tightens existing collagen fibers immediately, while Rejuran i stimulates new collagen formation over the following weeks. doi:10.1111/dsu.14852

What Our Patients Say About Rejuran Under Eye Treatment
“My dark circles made me look exhausted even after 8 hours of sleep. After 3 Rejuran i sessions at RE:BERRY, the difference is incredible. The under-eye area looks brighter and the fine lines have softened noticeably.”
“I was scared of getting filler under my eyes because of the Tyndall effect risk. Dr. Cho recommended Rejuran i instead, and I am so glad. Natural improvement, no bumps, no blue tinge. Exactly what I wanted.”
“The Eye Repair Package combining Oligio and Rejuran was the best investment. Both dark circles and the fine lines around my eyes improved significantly. The clinic near the airport made it easy to fit into my travel schedule.”
Frequently Asked Questions About Rejuran Under Eye Treatment
Expert answers about Eye Rejuran treatment at RE:BERRY Incheon Airport.
Rejuran 2cc (including under-eye focus) starts at ₩220,000 (regular ₩430,000, April promo). The Naturally Brighter Under-Eyes Package is ₩490,000. The Eye Repair Package (Eye Oligio 200 shots + Eye Rejuran 2cc) is ₩840,000. All prices exclude VAT.
Rejuran i has 40% lower viscosity and smaller particle size (100-300 kDa vs 750 kDa) specifically optimized for the thin periorbital skin. It creates fewer post-injection bumps and spreads more evenly, while delivering equivalent PDRN collagen-stimulating efficacy.
Most patients see meaningful improvement after 2-3 sessions spaced 2-3 weeks apart. Optimal results typically require 3-5 sessions. Maintenance sessions every 3-4 months sustain the collagen stimulation and skin thickening effects.
Topical numbing cream is applied for 20-30 minutes before injection. The 32-gauge needle is extremely fine, and most patients rate pain at 2-3 out of 10. The under-eye area has moderate nerve density, so some sensitivity is normal but brief.
Yes. Small injection bumps resolve within 24-48 hours. You can fly the same day if needed, though we recommend 24 hours for optimal healing. RE:BERRY Incheon Airport is minutes from ICN, open 365 days.
No. Tyndall effect (bluish discoloration) occurs only with hyaluronic acid fillers placed too superficially. Rejuran i contains polynucleotides, not HA, so there is zero risk of Tyndall effect — making it the safer choice for under-eye skin quality improvement.
Rejuran i is most effective for vascular dark circles (thin skin showing blood vessels) and mixed-type dark circles. It increases dermal thickness to reduce translucency. For structural dark circles (hollowing), Dr. Cho may combine Rejuran i with tear trough filler.
Results from a single session last 3-4 months. After a full course of 3-5 sessions, cumulative collagen improvement provides benefits lasting 6-12 months. Most patients maintain with 2-3 sessions per year.
Yes. Popular combinations include Rejuran i + Eye Oligio for comprehensive eye rejuvenation (the Eye Repair Package at ₩840,000), Rejuran i + under-eye filler for volume + quality, and Rejuran i + crow’s feet Botox for wrinkle + skin quality.
Very safe. Rejuran i was specifically designed for periorbital use with optimized viscosity and particle size. PDRN has an excellent safety profile — it is biocompatible, biodegradable, and non-immunogenic. Clinical studies report no serious adverse events.
Expect small injection papules (bumps) for 24-48 hours and mild redness. Bruising is possible but uncommon with proper technique. Apply ice packs for the first 4-6 hours. No eye makeup for 12 hours. Resume normal activities the same day.
All under-eye injections are performed by Dr. Cho Sung-Jun (Head Director, License #138858) or Dr. Kim Dong-Young (License #147291). Periorbital injection requires advanced precision — RE:BERRY does not delegate eye-area treatments to nurses.
Yes. Rejuran i stimulates collagen in the periorbital zone, softening fine lines around the eyes. For crow’s feet specifically, combining Rejuran i with neurotoxin (Botox) provides the best results — neurotoxin relaxes the muscle while Rejuran improves skin quality.
Significantly more effective. Eye creams only reach the epidermis (0.1-0.2mm depth). Rejuran i is injected at 1-2mm dermal depth, directly stimulating fibroblast collagen production. Clinical studies show 24-31% increase in dermal thickness — no topical product achieves this.
The Eye Repair Package (₩840,000, regular ₩1,670,000) combines Eye Oligio 200 shots (RF lifting for periorbital skin tightening) with Eye Rejuran 2cc (PDRN regeneration for dark circles and fine lines). This dual-mechanism approach addresses both laxity and skin quality in one session.
PRP therapy uses your own blood-derived growth factors for regeneration (zero allergy risk, broader growth factor spectrum) while Rejuran i uses salmon-derived PDRN (stronger evidence for periorbital skin thickening specifically). Both are effective — many patients benefit from alternating between the two.
Yes, with a minimum 3-hour layover. Treatment takes 30-45 minutes including numbing. RE:BERRY Incheon Airport offers airport pickup service and is open 365 days including holidays.
Four main causes: (1) Vascular — thin skin revealing underlying blood vessels; (2) Pigmented — excess melanin in the under-eye dermis; (3) Structural — tear trough hollowing creating shadow; (4) Mixed — combination of above. Asian patients most commonly have vascular or mixed type.
Yes. PDRN is effective for all Fitzpatrick skin types (I-VI). There is no risk of post-inflammatory hyperpigmentation. Results are consistent across ethnicities, though the specific dark circle type may vary.
Patients commonly start between ages 25-35, when early under-eye changes become noticeable. Prevention is easier than correction — younger patients often need fewer sessions. There is no maximum age limit.

Arrive with clean skin (no eye makeup). Discontinue retinoids and blood thinners 3-5 days before. Avoid alcohol for 24 hours prior. Inform your doctor of any eye conditions, allergies, or medications.
Rejuran HB is a hydration-focused formulation with added hyaluronic acid, primarily for overall skin hydration. Rejuran i is specifically formulated for the periorbital area with lower viscosity and smaller particle size. For under-eye treatment, Rejuran i is the recommended product.
RE:BERRY offers physician-only periorbital injection (never delegated to nurses), genuine Rejuran i product with lot verification, competitive pricing (₩220,000 vs ₩400,000+ at Seoul clinics), 8-language support, 365-day operation near the airport, and airport pickup service.
Absolutely. Approximately 30% of RE:BERRY’s under-eye treatment patients are male. Dark circles and tired-looking eyes affect both genders equally. The treatment protocol is identical, and results are equally effective for male periorbital skin.
Rejuran is a Korean-developed product (Pharma Research Products), and Korean clinics have the deepest experience with PDRN injection techniques. Korean clinics also offer significantly lower pricing (₩220,000 vs $500-800 USD abroad) and routinely combine Rejuran with complementary devices like Oligio RF for enhanced results.
