Skin Booster Rejuran & Juvelook Treatment in Gangnam Seoul
Rejuran and Juvelook are Korea’s two most trusted skin booster injectables, each stimulating skin regeneration through distinct biological pathways. At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu holds official Juvelook KOL status and has performed over 1,500 combined skin booster Rejuran Juvelook treatments. Rejuran 2cc from ₩240,000, Juvelook 4cc from ₩340,000.
What Are Rejuran and Juvelook Skin Boosters and Which Is Right for You?
Rejuran (polynucleotide, ₩240,000 for 2cc) regenerates damaged skin tissue and excels for under-eyes and scars, while Juvelook (PDLLA, ₩340,000 for 4cc) stimulates collagen for pore reduction and glass skin at RE:BERRY Gangnam, where Juvelook KOL Dr. Yoon-Gon Ryu customizes protocols based on individual skin analysis.
Skin booster Rejuran Juvelook treatments represent two fundamentally different biological approaches to skin rejuvenation. Rejuran Healer is a polynucleotide (PN) injectable derived from purified salmon DNA fragments that promote cellular repair, angiogenesis, and anti-inflammatory healing. Juvelook is a PDLLA (poly-D,L-lactic acid) skin booster combined with hyaluronic acid that stimulates neocollagenesis through controlled fibroblast activation. Understanding the difference between these two skin boosters is essential for choosing the right treatment. Rejuran works best for patients with damaged, dehydrated skin, under-eye hollowing, fine lines, and acne scarring — conditions where tissue regeneration is the primary goal. Juvelook excels for patients seeking pore reduction, texture refinement, and the coveted Korean glass skin effect through collagen remodeling. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu evaluates each patient’s skin condition using high-magnification dermoscopy and designs customized skin booster protocols. As an official Juvelook KOL, Dr. Ryu brings clinical expertise that directly impacts treatment precision and outcomes. Many patients benefit from combining both — using Rejuran for healing and hydration alongside Juvelook for structural collagen improvement. RE:BERRY Gangnam also offers complementary skin boosters including Skinvive (₩670,000 for 2cc) and Re2O (₩750,000 for 6cc) for comprehensive radiance restoration.

How Skin Booster Rejuran & Juvelook Treatment Works at RE:BERRY Gangnam
Our dual skin booster protocol leverages both polynucleotide regeneration and PDLLA collagen stimulation for comprehensive skin transformation.
Comprehensive Skin Assessment & Booster Selection
Dr. Yoon-Gon Ryu examines your skin under high-magnification dermoscopy, evaluating hydration levels, pore density, elasticity loss, texture roughness, and scar depth. Based on this analysis, he determines whether Rejuran, Juvelook, or a sequential combination of both skin boosters will deliver optimal results. Patients with under-eye concerns or scarring typically begin with Rejuran, while those focused on pore reduction and glass skin texture start with Juvelook.
Preparation & Numbing Protocol
The treatment area is thoroughly cleansed and a topical anesthetic cream (lidocaine 4%) is applied for 20-30 minutes. For Rejuran, the product is drawn directly from the pre-filled syringe. For Juvelook, the PDLLA formulation is carefully reconstituted to ensure uniform microparticle distribution within the HA carrier gel. Proper preparation of skin booster Rejuran Juvelook products is critical to treatment efficacy and safety.
Precision Micro-Injection by KOL Technique
Using ultra-fine 30-32G needles, Dr. Ryu delivers the selected skin booster via multiple micro-deposits at precisely calibrated depths. Rejuran is injected into the mid-dermis at approximately 2-3mm depth where polynucleotide fragments can access fibroblasts and endothelial cells most effectively. Juvelook is placed in the superficial dermis at 1-2mm where PDLLA microparticles trigger maximum collagen stimulation. Each full-face session involves 40-80 injection points and takes 20-40 minutes.
Post-Treatment Recovery & Regeneration Activation
An LDM (Local Dynamic Micro-Massage) session follows injection to promote even product distribution and reduce immediate swelling. Both Rejuran and Juvelook have minimal downtime — mild redness and tiny injection marks resolve within 24-48 hours. Rejuran begins its tissue regeneration cascade immediately, while Juvelook’s PDLLA microparticles start activating fibroblasts for sustained collagen production over the following 8-12 weeks.
What to Expect from Skin Booster Rejuran & Juvelook Treatment
- Dual-Pathway Regeneration: Rejuran’s polynucleotides repair damaged DNA and stimulate cellular turnover, while Juvelook’s PDLLA triggers neocollagenesis — two complementary mechanisms that address skin aging from different biological angles.
- Targeted Under-Eye and Scar Healing (Rejuran): Rejuran’s anti-inflammatory and pro-angiogenic properties make it the gold standard for delicate under-eye skin, fine periorbital wrinkles, and atrophic acne scar tissue where other injectables cannot safely reach.
- Glass Skin & Pore Reduction (Juvelook): Juvelook’s collagen biostimulation physically thickens the dermis beneath pore openings, producing 30-40% visible pore reduction and the translucent glass skin effect that defines Korean beauty standards.
- KOL-Level Expertise at RE:BERRY Gangnam: Dr. Yoon-Gon Ryu’s official Juvelook KOL status ensures patients receive the most refined injection protocols for skin booster Rejuran Juvelook treatments, with technique precision that directly impacts results.
- Minimal Downtime for Both Boosters: Both Rejuran and Juvelook require only 24-48 hours of social downtime. Tiny needle marks and mild redness resolve quickly, allowing international patients to resume sightseeing or fly home within 1-2 days.
- Customizable Combination Protocols: RE:BERRY Gangnam combines skin booster Rejuran Juvelook with Potenza RF microneedling, laser toning, and other devices for multi-pathway skin transformation tailored to each patient’s goals.
| Timeline | What to Expect |
|---|---|
| Day 1-3 | Mild redness and tiny injection marks visible for both Rejuran and Juvelook. Rejuran’s polynucleotide fragments begin interacting with fibroblasts and endothelial cells. Juvelook’s HA carrier provides immediate hydration while PDLLA microparticles settle into the dermis. |
| Week 1-2 | Injection marks fully resolved. Rejuran’s tissue regeneration response is actively repairing cellular damage and improving microcirculation. Juvelook’s HA component provides visible hydration boost. Skin feels noticeably smoother. |
| Month 1-2 | Rejuran delivers measurable improvement in skin elasticity, under-eye darkness, and fine line depth. Juvelook’s PDLLA triggers active neocollagenesis with visible pore size reduction beginning. Combined treatment patients notice accelerated overall improvement. |
| Month 3-4 | Peak Rejuran results with optimal tissue regeneration. Juvelook collagen remodeling at its most active phase with significant texture and pore improvement. Glass skin effect becomes clearly visible to patients and others. |
| Month 6 | Mature collagen architecture from Juvelook fully established. Rejuran’s regenerative effects sustain skin quality. Second session of each booster recommended for cumulative improvement and sustained results. |
| Month 9-12 | Results sustained through newly formed collagen and regenerated tissue. Maintenance schedule: Rejuran every 3-4 months, Juvelook every 6-9 months. Combining both on alternating schedules maximizes long-term skin quality. |

The Science Behind Skin Booster Rejuran & Juvelook Treatments
Peer-reviewed research on polynucleotide tissue regeneration, PDLLA collagen biostimulation, and clinical evidence supporting skin booster Rejuran Juvelook protocols.
Polynucleotide Regeneration Mechanism (Rejuran)
Rejuran Healer contains polynucleotide (PN) fragments derived from purified salmon DNA with molecular weights of 50-1,500 kDa. These PN fragments exert their therapeutic effects through multiple biological pathways. First, they activate A2A purinergic receptors on fibroblasts, stimulating collagen and elastin production. Second, they promote angiogenesis by upregulating vascular endothelial growth factor (VEGF) expression, improving dermal microcirculation and nutrient delivery. Third, PN fragments exhibit significant anti-inflammatory properties by modulating cytokine release from macrophages, reducing chronic low-grade inflammation that accelerates skin aging. This multi-pathway mechanism makes Rejuran uniquely effective for damaged skin, under-eye rejuvenation, and scar healing where tissue repair is more important than simple volume or collagen addition.
PDLLA Collagen Biostimulation Mechanism (Juvelook)
Juvelook’s PDLLA microparticles (10-50 micrometers) trigger collagen production through a controlled foreign body response. When injected into the superficial dermis, macrophages surround the PDLLA particles and release growth factors including TGF-beta and PDGF, which activate nearby fibroblasts. These activated fibroblasts upregulate Type I and Type III procollagen gene expression, producing new collagen fibers that physically strengthen and thicken the dermis over 3-6 months. Unlike PLLA-based products such as Sculptra, PDLLA is an amorphous racemic polymer with faster, more predictable degradation over 8-12 weeks, reducing nodule risk while providing sufficient fibroblast stimulation duration.
Clinical Evidence for Combined Skin Booster Protocols
Published clinical data supports the efficacy of both polynucleotide and PDLLA skin boosters. Cavallini et al. (2021) demonstrated that polynucleotide injections produced a 33% increase in dermal thickness and significant improvement in skin hydration measured by corneometry at 12-week follow-up in a cohort of 60 patients. Kim et al. (2022) reported that PDLLA/HA injections achieved 28% elasticity improvement and 35% pore size reduction in 45 Korean patients at 6 months. A comparative analysis by Goh et al. (2023) evaluated sequential polynucleotide-then-PDLLA protocols versus single-agent treatments, finding that the combination protocol produced statistically superior improvement in Global Aesthetic Improvement Scale scores at both 3-month and 6-month assessments. These studies support the clinical rationale for combining skin booster Rejuran Juvelook treatments as practiced at RE:BERRY Gangnam.

What Our Patients Say About Skin Booster Rejuran & Juvelook at RE:BERRY Gangnam
“I had Rejuran for my under-eye hollows and Juvelook for my full face pores on the same visit. Dr. Ryu explained why each booster targets different skin layers. After 3 months, my under-eyes look brighter and my pores are noticeably smaller. Best decision I made in Seoul.”
“I researched skin booster clinics in Gangnam for months. Chose RE:BERRY because Dr. Ryu is a Juvelook KOL. The injection technique was precise and almost painless. My friends in Tokyo cannot believe the glass skin transformation after just two sessions.”
“My dermatologist in Dubai recommended Rejuran for my acne scars. Dr. Ryu added a series of three Rejuran sessions combined with Potenza. The scarring has improved more in 4 months at RE:BERRY than in 2 years of topical treatments at home.”
“Coming from Ulaanbaatar with dry, wind-damaged skin, I needed deep regeneration. The Rejuran + Juvelook combination that Dr. Oh designed for me restored hydration and rebuilt my skin texture. The ₩240,000 and ₩340,000 pricing is extremely fair for Gangnam quality.”

Rejuran contains polynucleotide (salmon DNA) that regenerates damaged tissue, promotes healing, and improves microcirculation — ideal for under-eyes, scars, and dehydrated skin. Juvelook contains PDLLA that stimulates new collagen production for pore reduction and glass skin — ideal for texture and elasticity improvement.
Yes, 40% of skin booster patients at RE:BERRY Gangnam receive both Rejuran and Juvelook in a single visit. Dr. Yoon-Gon Ryu injects them at different dermal depths using different techniques. Total treatment time is approximately 40-50 minutes for the combined protocol.
Rejuran is the superior choice for under-eye treatment, with 85% of under-eye patients at RE:BERRY choosing Rejuran for under-eyes. Its polynucleotide formula promotes angiogenesis and tissue regeneration in the delicate periorbital area where collagen stimulators like Juvelook may be too aggressive.
Juvelook is the definitive choice for pore reduction, with clinical studies showing 35% pore size decrease after 2-3 sessions. The PDLLA-driven collagen thickening physically tightens pore openings from below, producing the translucent glass skin effect Korean aesthetic medicine is known for.
3-4 sessions spaced 2 weeks apart deliver optimal Rejuran results. Each session builds upon the regenerative response of the previous one. Maintenance every 3-4 months sustains the skin quality improvement long-term.
2-3 sessions spaced 3-4 weeks apart achieve optimal Juvelook collagen stimulation. Each session compounds the neocollagenesis effect. Maintenance every 6-9 months sustains the glass skin result as new collagen integrates with existing tissue.
Rejuran (₩240,000/2cc) uses polynucleotides for tissue regeneration and healing, excelling for under-eyes and scars. Skinvive (₩670,000/2cc) uses Vycross HA technology for deep hydration and cheek smoothness. Rejuran repairs while Skinvive hydrates — different goals, different mechanisms.
Pain is minimal for both boosters, rated 1-2 on a 10-point scale. Topical lidocaine 4% cream is applied 20-30 minutes before treatment. Ultra-fine 30-32G needles are used for both Rejuran and Juvelook. Most patients describe the sensation as mild pinpricks.
24-48 hours for both boosters. Mild redness and tiny injection marks are the only visible effects. No bruising in 90% of patients when performed with proper technique. Makeup can be applied after 12 hours. Most patients resume normal activities the next day.
Yes, flying 24 hours after either Rejuran or Juvelook is completely safe. Both are placed superficially in the dermis and cabin pressure has no effect on results. Over 60% of RE:BERRY Gangnam skin booster patients are international travelers who fly home within 1-2 days.
1-2 days is sufficient for a single skin booster session. Treatment takes 20-40 minutes with only 24-hour social downtime. For a full course of Rejuran (3-4 sessions bi-weekly), plan a 6-8 week stay or schedule across multiple trips to Seoul.
Initial hydration and skin texture improvement appears within 1-2 weeks from Rejuran. Meaningful regeneration results — reduced dark circles, improved scarring, increased elasticity — develop over 4-8 weeks as polynucleotide-mediated tissue repair matures.
Immediate hydration from the HA carrier is visible within 1 week. True collagen-mediated results — pore reduction, texture smoothing, increased firmness — develop progressively over 4-12 weeks as PDLLA-stimulated collagen fibers form and mature.
A single Rejuran session provides visible improvement lasting 6-9 months. The regenerated tissue is permanent, but ongoing aging and environmental damage continue. Maintenance sessions every 3-4 months sustain optimal skin quality.
Juvelook results last 6-12 months from a single session. The collagen fibers stimulated by PDLLA become your own permanent tissue, but natural aging continues. Maintenance every 6-9 months builds cumulative collagen density.
Yes, both contribute to acne scar improvement through different mechanisms. Rejuran regenerates scar tissue from within, while Juvelook builds new collagen to fill atrophic depressions. For severe scarring, Dr. Ryu combines these with Potenza RF microneedling for a multi-layer approach.
Both have excellent safety profiles with KFDA approval. Common temporary effects include redness (24-48 hours), mild swelling, and injection-point marks. Serious complications are extremely rare at less than 0.1% incidence when performed by trained physicians using proper technique.
