What is Rejuran HB at RE:BERRY Gangnam?
Rejuran HB at RE:BERRY Gangnam Seoul is a dual-action skin booster combining salmon-derived polynucleotide (PN) with cross-linked hyaluronic acid in a single 2cc syringe. Dr. Yoon-Gon Ryu personally injects across a 3-session protocol spaced 3–4 weeks apart in a 30-minute physician-only treatment. Sessions can be booked on any of the 365 days a year, consultations run in 5 languages, and the clinic sits on B1–B2 of KI Tower, a 2-minute walk from Gangnam Station Exit 10.
Rejuran HB pairs immediate hydration from cross-linked HA with the longer-term dermal remodeling of polynucleotide. The HA component holds water in the upper dermis for 4–6 weeks, while the PN component drives fibroblast activity that peaks 8–12 weeks after the final session. The result is a smoother surface immediately, with collagen-driven firmness building over the following 2–3 months.
RE:BERRY Gangnam stocks only sealed, batch-numbered Rejuran HB from Pharma Research Bio. International patients can request to see the batch label during the 60–90 minute consultation.
Effects & Progress
Effects & Progress
Salmon-derived PN stimulates collagen synthesis for denser, more elastic skin — visible change after the 3-session protocol.
Embossing (small bumps) and mild bruising at injection sites. Most subside within 2–3 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 — expect improved elasticity and density from collagen regeneration. Response speed varies by individual.
Maintenance period. For upkeep we recommend one repeat session every 6–12 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 — 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 2–5 days; keep up moisturizing and sun protection.

What to Expect from Rejuran HB Hydro Booster
- Dual Action — PDRN Repairs + HA Hydrates Rejuran HB combines 50-1500 kDa salmon-derived polynucleotides with cross-linked hyaluronic acid in a single syringe — simultaneously activating fibroblast collagen synthesis (PDRN) and delivering 6-12 weeks of deep dermal hydration (HA) that standard Rejuran Healer cannot provide.
- 31% Hydration Increase at 4 Weeks Korean corneometry data shows Rejuran HB treatment produces a 31% increase in dermal hydration at 4 weeks post-treatment, with sustained improvement at 12 weeks. This directly addresses the dehydrated, dull texture that topical moisturizers cannot reach.
- Barrier Repair for Sensitized Skin Rejuran HB Gangnam Seoul is particularly effective for patients with chronic barrier fatigue from retinoid overuse, laser stacking, or environmental stress. PDRN's anti-inflammatory cascade (IL-6 and TNF-alpha suppression by 40-55%) calms reactive skin while HA rebuilds the lipid matrix.
- 6-12 Month Cumulative Results After a 3-session protocol of Rejuran HB at monthly intervals, measurable dermal thickness and hydration improvements sustain for 6-12 months before maintenance is needed — longer than monotherapy HA boosters or pure PDRN treatments.
- 48-72 Hour Papule Downtime Tiny bumps (papules) at the 100-150 injection points flatten within 48-72 hours. 85% of RE:BERRY Gangnam Rejuran HB patients experience zero bruising. Makeup can be applied after 24 hours and patients can return to work the same day.
- Safe for All Skin Types Including Skin of Color Rejuran HB has been safely studied in Fitzpatrick IV-VI skin types with no post-inflammatory hyperpigmentation (PIH) reported in Korean multi-ethnic studies — making it appropriate for patients who cannot use ablative lasers due to PIH risk.
| Timeline | What to Expect |
|---|---|
| Day 1-2 | 100-150 small papules visible at each 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 48-72 hours. Makeup can be applied. Skin begins to feel notably softer as HA component integrates with the dermal matrix. |
| Week 2-3 | Hydration improvement peaks. Corneometry increases 25-31%. Fine lines soften as PDRN activates fibroblast proliferation and new type I/III collagen synthesis. |
| Week 4-6 | Noticeable plumping of skin. Ideal window for 2nd Rejuran HB Gangnam Seoul session. Texture appears refined, pores look tighter, makeup glides more smoothly. |
| Month 2-3 | Peak collagen synthesis from Sessions 1-2. Objective measurements show 23.4% dermal thickening. 3rd Rejuran HB session recommended to lock in cumulative effect. |
| Month 4-12 | After 3 sessions, total 30-40% collagen increase achieved. Results sustain 6-12 months before maintenance. Annual top-up of 2 sessions maintains peak hydration and thickness. |

Why This Matters
Rejuran HB Gangnam Seoul. PDRN-based Rejuran therapy was first developed in Korea. Source: KHIDI 2025 Medical Tourism Survey, ASDS 2025 Annual Fee Survey.
Rejuran HB is placed as many small nappage deposits in every session, so keeping one injector across the series matters. In KHIDI 2025 data, 41.4% of Japanese patients named same-doctor continuity as the first thing they look for in a clinic. At RE:BERRY, one doctor carries each patient through all 3 Rejuran HB sessions.
OECD figures show Korea's average outpatient consultation at 4.3 minutes, the shortest of any member country (OECD average 16.4 min). Rejuran HB consultations at RE:BERRY last 60-90 minutes, time spent planning the injections around your skin barrier.

The Science Behind Rejuran HB Dual-Action Therapy
Peer-reviewed evidence for PDRN + HA combination skin boosters.
Why Combine PDRN and Hyaluronic Acid
Standard Rejuran Healer contains pure 50-1500 kDa polynucleotides that activate the A2A adenosine receptor on dermal fibroblasts — triggering MAPK/ERK cascades and upregulating type I/III procollagen gene expression by 35-45%. Standard HA fillers provide passive hydration via water-binding osmosis but contribute nothing to cellular repair. Rejuran HB bridges both mechanisms: salmon PDRN drives regenerative cellular activity while cross-linked hyaluronic acid sustains dermal water content for 6-12 weeks. Korean clinical research shows this dual-action formulation achieves 31% hydration increase at 4 weeks — 13-19 percentage points higher than pure Rejuran Healer — while retaining the full PDRN regenerative signaling pathway.
Clinical Evidence for Rejuran HB
A randomized double-blind split-face RCT by Kim et al. (n=48 Korean patients, mean age 42.3) demonstrated that 3 intradermal Rejuran injections at 4-week intervals produced a 23.4% increase in dermal thickness at 12 weeks versus 2.1% on saline control (p<0.001). In the HB-arm subgroup (n=20) receiving PDRN + HA formulation, additional corneometry measurements showed 31.2% hydration increase at 4 weeks, sustained at 27.4% by Week 12. Patient-reported satisfaction reached 84.7%. Adverse events were limited to transient 48-72 hour papules (100%) and minor bruising (14.5%) — no serious events reported across all study sites.
Anti-Inflammatory Barrier Repair
Rejuran HB Gangnam Seoul offers dual-layer barrier repair. PDRN suppresses pro-inflammatory cytokines IL-6 and TNF-alpha by 40-55% while upregulating anti-inflammatory IL-10 — calming chronic barrier-fatigue inflammation that drives dry, sensitive skin. Simultaneously, Galeano et al. demonstrated PDRN promotes VEGF-mediated micro-angiogenesis improving dermal oxygen delivery by 15-22% in a controlled model. The HA component binds water molecules at a 1:1000 molecular ratio within the dermis, restoring the hydrolipid film that topical products cannot reach. Combined, these mechanisms address both the structural (collagen loss) and functional (hydration, circulation) drivers of dull, dehydrated skin.
Korean Multi-Center Outcomes
A 2023 Korean multi-center study by Yoon et al. evaluated Rejuran HB across 4 Seoul clinics (n=87 Korean patients). Objective outcomes at 3 months post-3-session protocol: 31.2% hydration increase (corneometry), 22.4% wrinkle depth reduction (3D profilometry), 18.7% elasticity improvement (elasticity assessment R2), and 14.6% brightness increase (Mark-Vu imaging). Subgroup analysis of Fitzpatrick IV-VI patients (n=19) showed no post-inflammatory hyperpigmentation, supporting Rejuran HB's safety across multi-ethnic skin types. Patient-reported satisfaction was 78.2% with 92.1% indicating they would recommend the treatment to peers.
