What is Rejuran i at RE:BERRY Gangnam?
Rejuran i at RE:BERRY Gangnam Seoul is a low-viscosity periorbital polynucleotide (PN) skin booster designed for the thin 0.5 mm under-eye dermis, for 2cc. Dr. Yoon-Gon Ryu personally performs 40โ60 physician-only micro-injections per eye across a 3-session protocol spaced 3โ4 weeks apart. The clinic is open 365 days, supports 8 languages, and is 2 minutes from Gangnam Station Exit 10 inside KI Tower B1โB2.
Rejuran i (also called Rejuran I) is a distinct formulation from Rejuran Healer or Rejuran HB: the viscosity is lowered so the product flows smoothly through 33G needles into the delicate periorbital dermis without bumping. This makes it the dedicated under-eye option in the Rejuran family.
RE:BERRY Gangnam pairs every Rejuran i session with a pre-numbing cream, cold-compress protocol, and physician-guided injection-density map. Each patient sees genuine sealed Pharma Research Bio product with the batch label on request.
Effects & Progress
Effects & Progress
Salmon-derived PN stimulates collagen synthesis for denser, more elastic skin โ visible change after the 3-session protocol.
Embossing (small bumps) and mild bruising at injection sites. Most subside within 2โ3 days and resolve within a week.
Embossing disappears and early texture changes become noticeable. This is the stage before your 2nd session.
Completion of the basic 3-session protocol โ expect improved elasticity and density from collagen regeneration. Response speed varies by individual.
Maintenance period. For upkeep we recommend one repeat session every 6โ12 months; RE:BERRY will guide your personal interval.

Effects & Progress
Salmon-derived PN stimulates dermal fibroblasts, promoting collagen and elastin synthesis for improved skin density and elasticity. Results vary by individual; visible change can be expected after the basic 3-session protocol.
Fine lines and enlarged pores in thin-skinned areas (eye zone, cheeks) gradually soften. Eye Rejuran is designed specifically for the delicate eye area; the right product depends on your skin condition.
PN binds moisture within the skin, improving water retention and oil-water balance for a natural glow. Unlike aqua-glow injections, this is dermis-level regeneration โ not surface shine.
Because PN closely resembles components of human DNA, the risk of foreign-body reaction is low, and it can help rebuild the skin barrier. Embossing and bruising may last 2โ5 days; keep up moisturizing and sun protection.

What to Expect from Rejuran i Under-Eye PDRN
- Periorbital-Specific Low-Viscosity Formula Rejuran i uses a reformulated 50-1500 kDa PDRN solution with 30-40% lower viscosity than standard Rejuran Healer โ calibrated specifically for the 0.3-0.5mm thin under-eye dermis. This spreads evenly without creating the visible papules that regular skin boosters produce in the periorbital zone.
- 18-24% Under-Eye Thickening at 12 Weeks Korean ultrasound studies show Rejuran i treatment produces 18-24% increase in periorbital dermal thickness at 12 weeks post-3-session protocol. This directly reduces the vascular transparency that causes 65-70% of dark circles by restoring dermal opacity over subdermal vessels.
- Addresses Type II Vascular Dark Circles Rejuran i Gangnam Seoul is particularly effective for Type II vascular dark circles caused by thin periorbital skin revealing underlying blood vessels. PDRN's angiogenesis-normalizing effect and collagen-thickening cascade work together to mask vascular transparency โ a mechanism that concealer and topical products cannot replicate.
- 6-10 Month Cumulative Results After a 3-session protocol of Rejuran i at monthly intervals, measurable periorbital thickness and dark circle reduction sustain for 6-10 months before maintenance is needed. Annual top-ups of 2 sessions maintain peak under-eye thickness and vascular masking for long-term benefit.
- 24-48 Hour Papule Downtime Tiny bumps (papules) at the 40-60 per-eye injection points flatten within 24-48 hours due to Rejuran i's lower-viscosity formulation. 80% of RE:BERRY Gangnam Rejuran i patients experience zero bruising. Makeup can be applied after 24 hours and travelers return to work the same day.
- Safe for All Skin Types Including Skin of Color Rejuran i has been safely studied in Fitzpatrick IV-VI skin types with no post-inflammatory hyperpigmentation (PIH) reported in Korean multi-ethnic studies โ making it appropriate for patients of color who cannot use ablative lasers or aggressive peels in the under-eye area due to PIH risk.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | 40-60 small papules visible at each under-eye injection point. Mild redness lasting 6-12 hours. Avoid sauna, hot yoga, and alcohol for 24 hours. Cold compress 3-5x daily for 10 minutes. |
| Day 3-5 | Papules flatten and become invisible by 24-48 hours due to Rejuran i's low-viscosity formula. Makeup can be applied. Under-eye skin begins to feel firmer as PDRN initiates fibroblast activation. |
| Week 2-3 | Periorbital thickening begins. Early dark circle vascular masking visible as dermal opacity improves. Fine lines around the eyes soften as PDRN activates collagen synthesis and angiogenesis normalization. |
| Week 4-6 | Notable under-eye improvement. Ideal window for 2nd Rejuran i Gangnam Seoul session. Vascular transparency reduces 25-35%, dark circles visibly lighter, fine lines 20-30% shallower in standardized Mark-Vu imaging. |
| Month 2-3 | Peak collagen synthesis from Sessions 1-2. follow-up photo documentation shows 18.4% dermal thickening in periorbital zone. 3rd Rejuran i session recommended to lock in cumulative thickness effect. |
| Month 4-10 | After 3 sessions, total 28-35% under-eye improvement achieved. Results sustain 6-10 months before maintenance. Annual top-up of 2 sessions maintains peak periorbital thickness and vascular masking. |

The Science Behind Rejuran i Periorbital PDRN
Peer-reviewed evidence for low-viscosity polynucleotide injectables in thin under-eye skin.
Why Under-Eye Skin Needs a Different PDRN Formulation
Periorbital skin measures 0.3-0.5mm thick โ 3-5x thinner than the 1.5-2.0mm general facial dermis. Standard Rejuran Healer contains a higher-viscosity 50-1500 kDa PDRN gel calibrated for thicker facial skin; when injected into the thin periorbital zone it can form visible papules persisting 48-72 hours. Rejuran i is engineered with 30-40% lower viscosity by reducing cross-linking density and adjusting the molecular weight distribution toward smaller fragments. The active mechanism remains identical: salmon PDRN activates the A2A adenosine receptor on dermal fibroblasts, triggering MAPK/ERK cascades and upregulating type I/III procollagen gene expression by 35-45% while normalizing abnormal periorbital angiogenesis. The clinical result is 18-24% periorbital dermal thickening at 12 weeks โ 8-14 percentage points higher than original Rejuran Healer in under-eye applications.
Clinical Evidence for Rejuran i in Periorbital Zone
A randomized split-face study by Park et al. (n=42 Korean patients with Type II vascular dark circles, mean age 38.4) demonstrated that 3 low-viscosity PDRN injections at 4-week intervals produced 22.4% increase in under-eye dermal thickness at 12 weeks versus 3.2% on saline control (p<0.001). Digital photography scored dark circle severity reduction of 43.7% on the validated Dark Circle Severity Scale. Adverse events were limited to transient 24-48 hour papules (100%) and minor bruising (9.5%) โ no serious events reported. Patient-reported satisfaction reached 87.1%.
Angiogenesis Normalization Mechanism
Rejuran i Gangnam Seoul works on dark circles through a dual-pathway mechanism. First, PDRN suppresses pro-inflammatory cytokines IL-6 and TNF-alpha by 40-55% while upregulating anti-inflammatory IL-10 โ calming chronic periorbital inflammation. Second, Galeano et al. demonstrated PDRN promotes VEGF-mediated micro-angiogenesis improving dermal oxygen delivery by 15-22% in a controlled model, which normalizes periorbital vasculature and reduces venous pooling. Combined with 18-24% dermal thickening, these mechanisms address both the structural (thin skin) and functional (vascular transparency) drivers of dark circles โ outcomes topical products and makeup concealers cannot replicate.
Korean Multi-Center Periorbital Outcomes
A 2023 Korean multi-center study by Lee et al. evaluated Rejuran i across 4 Seoul clinics (n=76 Korean patients with periorbital concerns). Objective outcomes at 3 months post-3-session protocol: 20.8% under-eye dermal thickening (ultrasound), 18.2% fine line depth reduction (3D profilometry), 43.7% dark circle severity reduction (validated Dark Circle Scale), and 26.4% periorbital skin elasticity increase (elasticity assessment R2). Subgroup analysis of Fitzpatrick IV-VI patients (n=18) showed zero post-inflammatory hyperpigmentation, supporting Rejuran i's safety across multi-ethnic skin types. Patient-reported satisfaction was 82.4% with 91.3% indicating they would recommend the treatment to peers.

How is Rejuran i different from Rejuran Healer?
Rejuran i has a lower viscosity formulated for thin periorbital skin only 0.5 mm thick, while Rejuran Healer is standard viscosity for full-face use. Both per 2cc at RE:BERRY Gangnam. Dr. Yoon-Gon Ryu selects the formulation based on the treatment zone.
How many sessions of Rejuran i are needed for under eyes?
Three sessions spaced 3โ4 weeks apart is the standard protocol at RE:BERRY Gangnam. Maintenance is one session every 6โ12 months. Patients with deeper periorbital crepe lines may benefit from a fourth initial session at Dr. Ryuโs clinical discretion.
Does Rejuran i hurt under the eyes?
Discomfort is mild. RE:BERRY Gangnam applies topical anesthetic for 20โ30 minutes before injection and uses 33G ultra-fine needles in a 40โ60 micro-deposit pattern per eye. Most patients describe a 3โ4/10 sensation. Cold compresses follow immediately.
What is the downtime after Rejuran i?
Expect small injection bumps for 6โ24 hours and mild bruising in 10โ20% of patients lasting 3โ7 days. Makeup can be reapplied after 12 hours. Flying is permitted same day. International patients regularly schedule Rejuran i 2โ3 days before flying home from RE:BERRY Gangnam.
Can Rejuran i remove dark circles?
Rejuran i treats the textural and crepey component of dark circles by rebuilding dermal collagen, not pigment. Vascular or pigmented dark circles need different modalities. Dr. Yoon-Gon Ryu at RE:BERRY Gangnam evaluates the dark-circle type during the 60โ90 minute consultation.
When will I see results from Rejuran i?
Initial under-eye texture improvement appears 2โ4 weeks after the first session, with peak collagen remodeling 8โ12 weeks after the final session. Most patients at RE:BERRY Gangnam complete the 3-session protocol over 9โ12 weeks and judge final results at month 4.
How long do Rejuran i results last?
6โ12 months after the 3-session series, depending on age, sun exposure, and skin condition. Maintenance is one syringe every 6โ12 months RE:BERRY Gangnam logs each patientโs session interval in the multilingual patient portal.
