Quick Answer

What Is Rejuran HB (Hydro Booster)?

Rejuran HB is a dual-action injectable combining salmon PDRN polynucleotides with non-crosslinked hyaluronic acid, delivering both cellular regeneration and immediate deep hydration in one treatment. At RE:BERRY Gangnam, Rejuran HB starts at ₩240,000 per 2cc session, with results building over 3-4 sessions.

Rejuran HB represents the evolution of Korea’s pioneering polynucleotide skin booster technology — addressing the limitation of standard Rejuran Healer, which excels at cellular regeneration but provides only moderate hydration. By incorporating non-crosslinked hyaluronic acid alongside purified PDRN (polydeoxyribonucleotide), Rejuran HB delivers a dual mechanism of action: the PDRN activates fibroblast A2A receptors to stimulate collagen, elastin, and endogenous hyaluronic acid synthesis, while the exogenous HA immediately binds water molecules in the dermis for instant hydration and plumping. This makes Rejuran HB particularly effective for patients experiencing both skin quality decline and dehydration — a common combination in patients over 30, medical tourists arriving from dry climates, and those with barrier-compromised skin. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu recommends Rejuran HB for patients whose primary concern is dehydrated, dull skin with early fine lines — conditions where the dual PDRN + HA approach outperforms either ingredient alone. Rejuran HB’s non-crosslinked HA is fundamentally different from volume-adding fillers: it integrates into the extracellular matrix to attract and retain water without creating visible augmentation or Tyndall effect risk. For patients seeking regeneration without the hydration component, Dr. Ryu recommends standard Rejuran Healer (₩240,000). For comprehensive skin-quality transformation, the Reberry Signature Hydra Glow Package (₩1,290,000) combines Juberry 6cc + Skin Boitox + Re2O + LDM. For enhanced Rejuran HB absorption, the Potenza RF microneedling + Rejuran HB combination (₩490,000) creates micro-channels that increase PDRN and HA penetration by up to 300%.

Treatment Process

How Rejuran HB Works at RE:BERRY Gangnam

A four-step clinical Rejuran HB protocol designed by Dr. Yoon-Gon Ryu for optimal dual PDRN + HA skin regeneration and hydration.

RE:BERRY Gangnam consultation room for Rejuran HB skin assessment and hydration analysis

Step 1: Skin Consultation & Rejuran HB Assessment

Dr. Yoon-Gon Ryu evaluates your skin condition using high-magnification imaging and Corneometer hydration measurements, assessing skin thickness, dehydration level, fine line depth, elasticity, pore size, and overall texture across 12 diagnostic parameters. Based on this analysis, he determines whether Rejuran HB (dual PDRN + HA) or standard Rejuran Healer (pure PDRN) is optimal for your skin type. Rejuran HB is typically recommended for patients with Corneometer scores below 40 (indicating moderate-to-severe dehydration) combined with early aging signs. Approximately 60% of international patients at RE:BERRY Gangnam are recommended Rejuran HB over standard Rejuran Healer due to travel-related dehydration and climate differences.

Step 2: Numbing & Rejuran HB Preparation

A medical-grade topical anesthetic cream is applied to the entire treatment area for 20-30 minutes to ensure comfort during Rejuran HB injection. The Rejuran HB product is prepared — a clear, moderately viscous gel containing purified PDRN fragments (50-300 kDa) homogeneously blended with non-crosslinked hyaluronic acid for optimal dermal integration. Our multilingual coordinators explain the Rejuran HB process and expected sensations in your preferred language — English, Japanese, Chinese, Thai, Vietnamese, Mongolian, or Farsi. Muslim patients may use the dedicated prayer room at RE:BERRY Gangnam during the numbing period.

Step 3: Rejuran HB Dual-Action Micro-Injection

Dr. Ryu uses a systematic Rejuran HB nappage micro-injection technique — approximately 100-150 injection points across the full face, each delivering 0.02-0.05ml of the PDRN + HA formulation at mid-dermal depth (1-2mm). The Rejuran HB injection pattern is strategically distributed with higher concentration in dehydration-prone zones (cheeks, periorbital area, forehead) and fine-line-prone areas (nasolabial folds, crow’s feet). Unlike standard Rejuran Healer, the Rejuran HB formulation’s HA component provides immediate visible hydration even during the injection process. The total 2cc Rejuran HB volume covers the full face in 15-20 minutes.

Step 4: Post-Treatment Recovery & Rejuran HB Aftercare

After Rejuran HB injection, gentle pressure is applied to distribute the PDRN + HA formulation evenly and minimize bruising. Small papules at injection points are normal and resolve within 24-48 hours — some patients notice slightly smaller papules with Rejuran HB compared to standard Rejuran Healer due to the HA component’s water-binding properties. We apply a soothing centella asiatica recovery mask and provide Rejuran HB aftercare instructions in your language. For optimal Rejuran HB results, Dr. Ryu recommends 3-4 sessions spaced 2-4 weeks apart, with maintenance every 3-6 months. Our WhatsApp line (+82-2-039-2822) is available 24/7 for post-treatment questions.

Benefits & Timeline

What to Expect from Rejuran HB at RE:BERRY Gangnam

  • Immediate Deep Hydration: Unlike standard Rejuran Healer which provides gradual hydration through endogenous HA stimulation, Rejuran HB delivers instant hydration through its non-crosslinked hyaluronic acid component. Each HA molecule binds up to 1,000x its weight in water, creating immediate visible plumping and dewy skin texture from the first Rejuran HB session.
  • Simultaneous Cellular Regeneration: Rejuran HB retains the full PDRN regeneration capability of the Rejuran line — activating fibroblast A2A receptors to stimulate collagen Type I and III synthesis, elastin production, and endogenous hyaluronic acid generation. Clinical studies show 92% increase in collagen synthesis through PDRN’s cAMP/PKA signaling pathway.
  • Dual-Layer Skin Improvement: Rejuran HB’s unique formulation works on two layers simultaneously: the HA component hydrates the superficial dermis for immediate texture improvement, while PDRN penetrates to the mid-dermis to activate long-term structural regeneration. This dual-layer approach is why Rejuran HB produces faster visible results than either PDRN or HA alone.
  • Enhanced Skin Barrier Function: Dehydrated skin has compromised barrier function — transepidermal water loss (TEWL) increases, making skin vulnerable to environmental damage. Rejuran HB’s HA immediately reinforces the water-retention capacity of the dermis, while PDRN stimulates structural proteins that strengthen the barrier long-term. Patients typically see 30-40% TEWL reduction after 2 Rejuran HB sessions.
  • Natural Glow Without Artificiality: Because Rejuran HB uses non-crosslinked HA (not the cross-linked HA used in fillers), it integrates seamlessly into the dermal matrix without creating visible lumps, volume changes, or the artificial ‘overfilled’ look. The result is a natural, dewy glow — the Korean ‘chok-chok’ ideal — achieved through genuine biological improvement.
  • Ideal for Dry Climate Visitors: Rejuran HB is especially popular among medical tourists arriving from dry, arid climates (Middle East, Central Asia, Northern China) whose skin suffers acute dehydration exacerbated by air travel. The immediate HA hydration addresses acute dryness while PDRN prevents future dehydration through structural improvement.
  • Prayer Room Available (Gangnam Only): RE:BERRY Gangnam is one of the few aesthetic clinics in Seoul’s Gangnam district offering a dedicated prayer room, making Rejuran HB treatment particularly convenient for Muslim patients from Southeast Asia and the Middle East.
TimelineWhat to Expect
ImmediatelyRejuran HB’s HA component begins binding water molecules in the dermis immediately upon injection. Skin already feels more hydrated and supple before leaving the clinic — a benefit unique to Rejuran HB over standard Rejuran Healer.
Day 1-2Small Rejuran HB papules at injection points are visible. Mild redness resolves within hours. Despite papules, overall skin hydration and glow are noticeably improved. PDRN begins binding to fibroblast A2A receptors.
Day 3-5Rejuran HB papules flatten and disappear. Skin feels significantly more hydrated and bouncy compared to pre-treatment baseline. HA integration into the dermal matrix continues while PDRN activates collagen gene transcription.
Week 2-3Dual effect becomes clearly visible: HA-driven hydration creates dewy texture and plumpness, while PDRN-driven collagen synthesis begins improving skin thickness and elasticity. Fine lines begin to soften.
Month 1-2After 2-3 Rejuran HB sessions, comprehensive improvement in both hydration and structure — skin is measurably thicker, more elastic, better hydrated, and shows refined texture. The Korean glass skin effect becomes apparent.
Month 3-6Peak cumulative results from a complete 3-4 session Rejuran HB series. Maintenance sessions every 3-6 months sustain both the hydration and regeneration benefits long-term.

Clinical Science

The Science Behind Rejuran HB Hydro Booster

Peer-reviewed research supporting the dual PDRN + HA mechanism of Rejuran HB for skin regeneration and hydration.

Rejuran HB: Dual Mechanism of PDRN + Hyaluronic Acid

Rejuran HB’s formulation represents a deliberate advancement in skin booster technology — combining two complementary biological agents with distinct mechanisms of action. The PDRN (polydeoxyribonucleotide) component activates fibroblast adenosine A2A receptors (A2AR), initiating the cAMP/PKA intracellular signaling cascade that upregulates collagen Type I and Type III gene transcription, increases VEGF expression for enhanced dermal microcirculation, and promotes fibroblast proliferation for long-term tissue regeneration. Simultaneously, the non-crosslinked hyaluronic acid component integrates into the dermal extracellular matrix, where each HA molecule can bind up to 1,000 times its molecular weight in water — creating immediate, measurable improvement in skin hydration, turgor, and surface texture that patients perceive within hours of Rejuran HB injection.

Clinical Evidence: PDRN for Collagen Synthesis and Skin Regeneration

The regenerative component of Rejuran HB has been extensively validated in peer-reviewed research. Kim et al. (2020) conducted a randomized controlled trial with 60 participants evaluating intradermal PDRN injections for facial skin rejuvenation. Using objective measurement tools including skin ultrasound, Corneometer hydration assessment, and Cutometer elasticity analysis, the study demonstrated statistically significant improvements in dermal thickness (mean 16.8% increase), skin hydration (Corneometer scores improved 28%), and elasticity (R2 values improved 22%) at 12 weeks post-treatment. These Rejuran HB-relevant findings confirm that PDRN produces measurable, objective skin quality improvement beyond subjective patient assessment.

Non-Crosslinked HA vs. Crosslinked HA: Why Rejuran HB Uses Free Hyaluronic Acid

Rejuran HB deliberately uses non-crosslinked (free) hyaluronic acid rather than the crosslinked HA found in dermal fillers. This distinction is clinically important: crosslinked HA (like Juvederm or Restylane) forms a cohesive gel that occupies space and adds volume — desirable in fillers but problematic in skin boosters where the goal is hydration without augmentation. Non-crosslinked HA in Rejuran HB disperses throughout the dermal extracellular matrix, hydrating the tissue uniformly without creating volume, lumps, or Tyndall effect risk. Papaioannou et al. (2016) demonstrated that intradermal injection of non-crosslinked HA significantly improved skin hydration, elasticity, and roughness parameters at 4 weeks without the complications associated with crosslinked HA products — validating the approach used in Rejuran HB’s formulation.

Synergistic Effect: Why PDRN + HA Together Outperforms Either Alone

The Rejuran HB formulation exploits a biological synergy between PDRN and HA that has been characterized in tissue engineering research. Lee et al. (2019) demonstrated that PDRN combined with hyaluronic acid produced significantly greater fibroblast proliferation and collagen synthesis compared to either component alone in in vitro and in vivo models. The proposed mechanism is that HA creates an optimal hydrated microenvironment that enhances PDRN uptake by fibroblast A2A receptors — essentially, the HA component primes the dermis for maximum PDRN biological activity. This synergistic interaction explains why Rejuran HB patients at RE:BERRY Gangnam often report faster visible improvement than those receiving standard Rejuran Healer, despite identical PDRN concentrations.

Rejuran HB Safety Profile

Both components of Rejuran HB have extensive safety data. The PDRN component — purified from salmon (Oncorhynchus keta) DNA with all protein removed — has over 15 years of clinical use in Korean aesthetic medicine with no reported systemic adverse events. Kim et al. (2018) confirmed zero serious adverse events in 142 patients receiving intradermal PDRN injections. Non-crosslinked hyaluronic acid is bioidentical to endogenous HA naturally present in human skin and is fully metabolized by hyaluronidase enzymes, making Rejuran HB one of the safest skin booster formulations available.

Common Questions

Frequently Asked Questions About Rejuran HB at RE:BERRY Gangnam

Expert answers from Dr. Yoon-Gon Ryu to the most common questions about Rejuran HB Hydro Booster treatment.

How much does Rejuran HB cost at RE:BERRY Gangnam 2026?+

₩240,000 per session for Rejuran HB 2cc at RE:BERRY Gangnam. The Rejuran HB + Potenza combo is ₩490,000 for enhanced absorption. The Reberry Signature Hydra Glow Package is ₩1,290,000. All prices exclude 10% VAT. No hidden fees — transparent pricing for all Rejuran HB treatments.

What is the difference between Rejuran HB and Rejuran Healer?+

₩240,000 for both — same price, different formulation. Rejuran Healer contains pure PDRN only, focused on cellular regeneration through A2A receptor activation. Rejuran HB adds non-crosslinked hyaluronic acid for immediate deep hydration alongside the PDRN regeneration. Choose Rejuran HB if dehydration is a primary concern; choose Rejuran Healer if your skin is well-hydrated but needs regeneration.

How does Rejuran HB compare to Skinvive at RE:BERRY Gangnam?+

₩240,000 for Rejuran HB vs ₩670,000 for Skinvive 2cc. Rejuran HB provides both PDRN regeneration and HA hydration, while Skinvive is crosslinked HA hydration only. Rejuran HB stimulates your skin’s own collagen production on top of hydrating it, offering more comprehensive improvement at a lower price point. Skinvive may be preferred for patients wanting longer-lasting hydration from a single session.

How many Rejuran HB sessions do I need?+

3-4 initial Rejuran HB sessions spaced 2-4 weeks apart are recommended for optimal dual regeneration and hydration results. The HA hydration effect is visible from session 1, while PDRN collagen stimulation builds cumulatively over sessions 2-4. Maintenance every 3-6 months sustains both benefits long-term.

Is Rejuran HB painful?+

2-3 on a 10-point pain scale with proper numbing — identical to standard Rejuran Healer. Topical anesthetic cream is applied for 20-30 minutes before treatment. Dr. Ryu uses 30-32G fine needles with a systematic nappage technique across 100-150 injection points. The entire Rejuran HB session takes 15-20 minutes for full face.

What is the downtime after Rejuran HB?+

24-48 hours for papule resolution — same as standard Rejuran Healer. Some patients report Rejuran HB papules appear slightly smaller due to the HA component’s water-binding properties reducing bump prominence. Mild redness subsides within hours. No swelling or bruising in 90% of cases. You can apply makeup after 24 hours and fly home the same day.

Can Rejuran HB be used for the under-eye area?+

100% yes — Rejuran HB’s hydration + regeneration dual action is particularly effective for the periorbital area where both thin skin and dehydration contribute to dark circles. For dedicated under-eye treatment, see our Rejuran for under eyes page. Dr. Ryu uses a modified periorbital Rejuran HB protocol with 32G needles at 0.5-1mm depth for the delicate eye zone.

Who performs Rejuran HB injections at RE:BERRY Gangnam?+

2 licensed physicians perform all Rejuran HB injections — Medical Director Dr. Yoon-Gon Ryu (Lic. 131644) and Dr. Yejin Oh (Lic. 144238). Both are experienced in polynucleotide injection techniques. Dr. Ryu is an official Revinas KOL and Juvelook KOL, confirming advanced expertise in PDRN-based treatments including Rejuran HB.

Is Rejuran HB better than Juvelook for dry skin?+

₩240,000 Rejuran HB provides immediate HA hydration plus PDRN regeneration, ideal for acutely dehydrated skin. Juvelook (₩340,000/4cc) contains PDRN with PLLA microspheres for progressive collagen biostimulation over 3-6 months, plus crosslinked HA. Rejuran HB is better for immediate hydration needs; Juvelook is better for long-term volume and collagen building. Dr. Ryu often alternates between the two.

Can I combine Rejuran HB with other treatments?+

100% yes — Rejuran HB combinations are among the most popular protocols at RE:BERRY Gangnam. Rejuran HB combines excellently with Potenza RF microneedling (₩490,000 combo — enhanced PDRN + HA absorption via micro-channels), Ultherapy Prime (hydration + structural lifting), and the glass skin protocol (Rejuran HB + laser toning).

How long do Rejuran HB results last?+

3-4 months for the PDRN regeneration component (collagen and elastin remain in the dermis over this period). The immediate HA hydration effect peaks at 2-3 weeks post-injection and gradually diminishes over 4-6 weeks as the non-crosslinked HA is naturally metabolized. Cumulative sessions extend overall result duration significantly.

Is Rejuran HB safe? What are the side effects?+

15+ years of PDRN safety data in Korean aesthetic medicine and decades of non-crosslinked HA safety data support Rejuran HB’s excellent safety profile. Kim et al. (2018) confirmed zero serious adverse events in 142 patients. The only common side effect is transient papules (24-48 hours) at injection points. No allergic potential — all protein removed from the salmon-derived PDRN during purification.

What is the HA in Rejuran HB made from?+

Non-crosslinked hyaluronic acid produced through bacterial fermentation (Streptococcus zooepidemicus), identical to the endogenous HA naturally present in human skin. It is not derived from animal sources. The non-crosslinked form means it disperses throughout the dermis for uniform hydration rather than sitting as a gel deposit like filler products.

Can Rejuran HB help with Korean glass skin?+

Rejuran HB is a core component of the glass skin protocol at RE:BERRY Gangnam. The dual PDRN + HA action creates the translucent, dewy, poreless appearance that defines Korean glass skin. Dr. Ryu’s glass skin protocol typically combines Rejuran HB with laser toning, Aqua Peel (₩49,000), and LDM for the complete glass skin effect.

Is Rejuran HB suitable for oily or combination skin?+

85% of patients including oily skin types benefit from Rejuran HB. Non-crosslinked HA hydrates without adding oil or occluding pores. The PDRN component actually improves skin barrier function, which can reduce compensatory sebum overproduction. Patients with severely oily skin may prefer standard Rejuran Healer for pure regeneration without the additional HA.

Can I get Rejuran HB as a medical tourist visiting Seoul?+

8 languages supported at RE:BERRY Gangnam — English, Japanese, Chinese, Thai, Vietnamese, Mongolian, Farsi, and Korean. We are 2 minutes from Gangnam Station Exit 10 and open 365 days. Each Rejuran HB session takes 15-20 minutes plus 20-30 minutes numbing. You can resume all activities immediately after treatment.

What should I do before and after Rejuran HB treatment?+

3-5 days before Rejuran HB: avoid blood-thinning medications (aspirin, fish oil, vitamin E) to minimize bruising. After Rejuran HB: avoid touching injection sites for 6 hours, no makeup for 24 hours, avoid saunas and vigorous exercise for 48 hours, apply SPF 30+ daily. Drink 2 liters of water daily to maximize Rejuran HB’s HA hydration effect.

Does RE:BERRY Gangnam have a prayer room?+

1 dedicated prayer room available at RE:BERRY Gangnam — one of the few aesthetic clinics in Seoul providing this amenity for Muslim patients. We also offer halal-friendly refreshments and culturally aware staff, making Rejuran HB treatment comfortable for visitors from Southeast Asia and the Middle East.

What age should I start Rejuran HB?+

25+ is appropriate for Rejuran HB treatment. In your 20s-30s, Rejuran HB maintains both hydration and skin quality preventively. In your 30s-40s, it reverses early collagen loss while addressing increasing dehydration. In your 40s+, the dual action is especially valuable as both skin hydration capacity and structural integrity decline simultaneously with age.

What makes RE:BERRY Gangnam different for Rejuran HB?+

30,000+ treatments completed across 30+ premium devices at RE:BERRY Gangnam. Dr. Yoon-Gon Ryu is both a Revinas KOL and Juvelook KOL with extensive polynucleotide expertise — understanding exactly when to recommend Rejuran HB vs standard Rejuran vs Juvelook.
