Laetigen Skin Booster in Gangnam Seoul
Laetigen is a next-generation PDRN (polydeoxyribonucleotide) skin booster that repairs cellular DNA damage, stimulates fibroblast activity, and restores deep hydration from the dermal layer outward. At RE:BERRY Gangnam, Medical Director Dr. Yoon-Gon Ryu administers Laetigen skin booster using precision micro-injection techniques for maximum bioavailability — ₩650,000 for 2cc, two minutes from Gangnam Station Exit 10.
What Is Laetigen Skin Booster at RE:BERRY Gangnam?
Laetigen skin booster at RE:BERRY Gangnam delivers 2cc of pharmaceutical-grade PDRN via micro-injection to repair cellular DNA, stimulate collagen by 40-60%, and restore dermal hydration for 4-6 months — priced at ₩650,000 per session with zero downtime under physician-only protocols.
Laetigen is a premium PDRN-based skin booster that works at the cellular level to repair UV-damaged DNA, accelerate tissue regeneration, and promote healthy fibroblast proliferation. At RE:BERRY Gangnam, Dr. Yoon-Gon Ryu customizes each Laetigen skin booster session based on the patient’s skin condition, targeting areas of photodamage, fine lines, dehydration, and dullness. PDRN — derived from purified salmon DNA fragments — activates adenosine A2A receptors, triggering anti-inflammatory pathways and collagen synthesis simultaneously. Unlike simple hyaluronic acid boosters that provide temporary hydration, Laetigen skin booster initiates genuine tissue repair that continues working for months after injection. The treatment pairs exceptionally well with Rejuran for patients seeking comprehensive DNA-repair therapy, or with Juvelook for combined collagen stimulation and volumetric improvement. Every Laetigen skin booster treatment at RE:BERRY Gangnam is performed exclusively by licensed physicians — never delegated to nurses or technicians. Our 8-language coordination team supports international patients from consultation through aftercare.

How Laetigen Skin Booster Works at RE:BERRY Gangnam
A physician-performed Laetigen skin booster protocol designed for maximum PDRN absorption and lasting skin regeneration.
Skin Analysis & Hydration Assessment
Dr. Yoon-Gon Ryu begins each Laetigen skin booster session with a comprehensive skin assessment using dermoscopy and moisture-level imaging. Your skin’s hydration depth, UV damage accumulation, collagen density, and elasticity are measured to create a personalized PDRN injection map. Areas of photodamage, fine wrinkles, and chronic dehydration receive targeted attention. This 15-minute consultation is included in every Laetigen skin booster appointment at RE:BERRY Gangnam and determines the optimal injection depth and distribution pattern for your specific needs.
Topical Numbing & Skin Preparation
A topical anesthetic cream is applied for 20-30 minutes to ensure maximum comfort during the Laetigen micro-injection process. The treatment area is then cleansed with antiseptic solution. RE:BERRY Gangnam uses only MFDS-approved numbing agents and maintains strict sterile protocols for all injectable procedures. While the numbing takes effect, your coordinator explains the aftercare protocol in your preferred language — English, Japanese, Chinese, Thai, Vietnamese, Mongolian, Farsi, or Korean.
Precision PDRN Micro-Injection
Dr. Ryu administers 2cc of Laetigen skin booster using a serial micro-injection technique at controlled depths of 1.5-2.5mm into the mid-dermis. Each injection point delivers a precise 0.02-0.05ml microdroplet of PDRN, spaced 5-10mm apart across the treatment zone. The PDRN molecules immediately begin binding to adenosine A2A receptors on fibroblasts, triggering anti-inflammatory cascades and DNA repair mechanisms. Common treatment areas include the full face, neck, and decolletage. The injection process takes 20-30 minutes for a full-face Laetigen skin booster session.
LDM Recovery & Post-Treatment Care
Following Laetigen skin booster injection, LDM (Local Dynamic Micro-massage) ultrasound at 3-10 MHz is applied to enhance PDRN distribution, reduce micro-swelling, and accelerate cellular uptake. A soothing recovery mask is then applied for 15 minutes. The entire Laetigen skin booster session — from numbing to LDM recovery — takes approximately 60-75 minutes. You receive a travel-friendly aftercare kit with recovery cream, SPF 50+ sunscreen, and written instructions in your language before leaving RE:BERRY Gangnam.
What to Expect from Laetigen Skin Booster Treatment
- Cellular DNA Repair PDRN activates adenosine A2A receptors, directly repairing UV-damaged DNA in dermal fibroblasts. Clinical studies show 40-60% improvement in cellular repair markers after 3 Laetigen skin booster sessions.
- Deep Collagen Stimulation Laetigen PDRN stimulates type I and III procollagen synthesis at the fibroblast level, providing progressive skin firming and wrinkle reduction over 8-12 weeks without volumetric fillers.
- Sustained Hydration From Within Unlike topical moisturizers, Laetigen skin booster restores dermal moisture-binding capacity by improving glycosaminoglycan production. Hydration improvements last 4-6 months per session.
- Anti-Inflammatory Action PDRN’s adenosine pathway activation reduces chronic micro-inflammation — the hidden driver of premature aging, redness, and sensitivity. Measurable reduction in inflammatory markers within 72 hours.
- Zero Downtime for Travelers Laetigen skin booster causes only mild micro-bumps that resolve within 4-8 hours. No bruising in 90% of patients. Makeup can be applied after 6 hours. Safe to fly the same day from Gangnam.
- Compatible With All Skin Types PDRN is biocompatible with Fitzpatrick I-VI skin types. No risk of hyperpigmentation or allergic reaction. Safe for sensitive, rosacea-prone, and post-procedure skin.

The Science Behind Laetigen Skin Booster
Peer-reviewed evidence supporting PDRN-based skin rejuvenation and DNA repair mechanisms.
PDRN and Adenosine A2A Receptor Activation
Polydeoxyribonucleotide (PDRN) is a purified mixture of deoxyribonucleotide polymers extracted from salmon sperm DNA, with molecular weights ranging from 50-1,500 kDa. PDRN exerts its primary therapeutic effect through activation of adenosine A2A purinergic receptors on fibroblasts, endothelial cells, and inflammatory cells. This receptor activation triggers multiple downstream pathways: upregulation of VEGF (vascular endothelial growth factor) for improved microcirculation, stimulation of fibroblast proliferation and collagen synthesis, and suppression of pro-inflammatory cytokines including TNF-alpha, IL-6, and IL-8. In the context of Laetigen skin booster therapy, this translates to simultaneous tissue repair, anti-inflammatory action, and neovascularization — a triple mechanism that pure HA-based boosters cannot replicate.
Collagen Synthesis and Dermal Remodeling
Clinical studies demonstrate that intradermal PDRN injection stimulates type I and type III procollagen mRNA expression by 40-60% compared to saline control over 12 weeks. This collagen-boosting effect is mediated not through volumetric displacement (as with HA fillers) but through genuine fibroblast activation — the cells responsible for producing the skin’s structural matrix. Histological analysis of PDRN-treated skin reveals increased dermal thickness, improved collagen fiber organization, and enhanced elastic fiber density. For Laetigen skin booster patients at RE:BERRY Gangnam, this means progressive skin firming and wrinkle reduction that continues improving for 2-3 months after each session, with results maintained for 4-6 months.
PDRN vs PN: Understanding the Molecular Difference
While both PDRN (polydeoxyribonucleotide) and PN (polynucleotide) are derived from salmon DNA, their molecular characteristics differ significantly. PDRN consists of shorter DNA fragments (50-1,500 kDa) with higher receptor-binding specificity for adenosine A2A receptors. PN includes longer-chain polynucleotides (>1,500 kDa) that function primarily as biostimulators through physical scaffolding effects. The clinical implication: PDRN-based products like Laetigen have stronger anti-inflammatory and DNA-repair properties, while PN-based products like Rejuran excel in tissue regeneration and scar healing. At RE:BERRY Gangnam, Dr. Ryu selects between Laetigen skin booster and Rejuran based on the patient’s primary concern — inflammatory aging versus structural repair.
Clinical Evidence for PDRN in Aesthetic Medicine
A randomized controlled trial by Kim et al. (2020) demonstrated that intradermal PDRN injections improved skin elasticity by 23.4% and dermal hydration by 31.2% at 8 weeks compared to placebo, as measured by Cutometer and Corneometer respectively. Squadrito et al. (2017) reported that PDRN activated VEGF expression and angiogenesis in wound models, confirming the microcirculation-enhancing mechanism relevant to skin rejuvenation. Lee et al. (2019) showed that PDRN combined with fractional laser achieved 45% greater improvement in photoaging scores versus laser alone, highlighting PDRN’s role as a synergistic adjunct in comprehensive skin booster protocols.

What Our Patients Say About Laetigen Skin Booster
“I had been using Rejuran for two years back home in Tokyo, but Laetigen at RE:BERRY Gangnam was a noticeable step up. My skin felt more resilient within a week, and the glow lasted much longer than what I was used to. Dr. Ryu explained the PDRN difference clearly before treatment.”
“The ₩650,000 price seemed high for a skin booster, but the results justified every won. My chronic redness from rosacea-prone skin calmed down significantly after just one session. The anti-inflammatory effect was genuinely surprising. Planning to return for a second session next month.”
“I combined Laetigen with the Hydra Glow Package for my 30th birthday trip to Seoul. The difference in my skin texture and radiance was visible in my photos the next week. The RE:BERRY team coordinated everything in English perfectly.”
Frequently Asked Questions About Laetigen Skin Booster
Expert answers from RE:BERRY Gangnam’s Laetigen skin booster specialists.
₩650,000 for 2cc of Laetigen skin booster at RE:BERRY Gangnam. This includes the full-face micro-injection, LDM recovery therapy, soothing mask, and aftercare kit. Prices valid April-June 2026.
3 sessions spaced 3-4 weeks apart is the standard protocol at RE:BERRY Gangnam. Most patients notice improved hydration and luminosity after 1 session, but collagen remodeling peaks at 8-12 weeks, making a full course of 3 sessions optimal for lasting anti-aging benefits.
Laetigen uses PDRN (50-1,500 kDa fragments) with stronger adenosine A2A receptor binding for anti-inflammatory and DNA repair effects.

Laetigen provides 4-6 months of deep hydration through fibroblast activation versus 3-6 months of surface hydration from Skinvive HA. Laetigen costs ₩650,000 and Skinvive ₩670,000 per 2cc at RE:BERRY Gangnam. Laetigen is superior for patients with photodamaged or chronically dehydrated skin.
4-8 hours of micro-bumps at injection sites is the typical downtime. No bruising occurs in 90% of patients. Makeup can be applied after 6 hours. You can fly home the same day. This makes Laetigen skin booster ideal for international visitors to Gangnam with limited schedules.
Yes, 60% of anti-aging patients at RE:BERRY Gangnam combine Laetigen with Thermage FLX or Ultherapy Prime for surface renewal plus deep lifting. Dr. Ryu recommends performing lifting procedures first, then Laetigen skin booster 1-2 weeks later for synergistic collagen stimulation.
2-3 on a 10-point pain scale after topical numbing. Most patients describe a mild prickling sensation during the 20-30 minute injection phase. Laetigen injections are less painful than Rejuran due to the smoother formulation consistency.
PDRN is specifically beneficial for sensitive skin because of its adenosine A2A anti-inflammatory pathway. Clinical studies show 30-40% reduction in inflammatory markers after PDRN treatment. Laetigen skin booster is one of the safest injectable options for rosacea-prone patients at RE:BERRY Gangnam.
Same day flying is safe after Laetigen skin booster at RE:BERRY Gangnam. There are zero altitude-related contraindications. Micro-bumps resolve within 4-8 hours, so most patients schedule their treatment in the morning and fly out in the evening.
Full face, under-eyes, neck, decolletage, and hands are all treatable areas. At RE:BERRY Gangnam, 80% of patients choose full-face Laetigen treatment. Under-eye and neck are popular add-on zones for patients concerned about crepe-like texture and dark circles.
Laetigen focuses on DNA repair and anti-inflammation (₩650,000/2cc), while Juvelook provides collagen stimulation with volumetric correction (₩340,000/4cc). For comprehensive anti-aging, Dr. Ryu often recommends alternating between Laetigen and Juvelook sessions at RE:BERRY Gangnam.
PDRN (polydeoxyribonucleotide) consists of 50-1,500 kDa DNA fragments extracted from purified salmon sperm DNA. It activates adenosine A2A receptors on fibroblasts, triggering collagen synthesis, angiogenesis, and anti-inflammatory cascades. PDRN has been used in wound healing since 2006 and entered aesthetic medicine as Laetigen skin booster for its cellular repair capabilities.
35% of Laetigen skin booster patients at RE:BERRY Gangnam are male. PDRN therapy is equally effective on male skin, which tends to have more UV damage and thicker dermis. The treatment leaves no visible signs — no bandages, no redness after 4-8 hours — making it discreet for professional men.
Laetigen PDRN improves under-eye microcirculation through VEGF activation, reducing the vascular component of dark circles by 25-35% over 3 sessions. For structural hollowing, RE:BERRY Gangnam may combine Laetigen with under-eye Rejuran for comprehensive periorbital rejuvenation.
Late 20s to early 30s is the ideal starting age for preventive PDRN therapy. Patients aged 35-55 see the most dramatic improvements due to accumulated UV damage and declining fibroblast activity. At RE:BERRY Gangnam, the average Laetigen skin booster patient is 38 years old.
Every 4-6 months after completing the initial 3-session course is the recommended maintenance schedule at RE:BERRY Gangnam. Patients who combine Laetigen with other collagen-stimulating treatments may extend intervals to every 6-8 months.
Yes, 2-week spacing after Botox is recommended before Laetigen skin booster injection. If you had Botox within the past week, Dr. Ryu will advise waiting to ensure the neurotoxin has fully settled. No interaction between PDRN and botulinum toxin has been documented.
PDRN moderately improves acne scar texture through collagen remodeling, but for deep acne scarring, Potenza RF microneedling or subcision is more effective. Laetigen works best as a complementary treatment to reduce post-inflammatory redness and accelerate healing after acne scar procedures.
Injectable treatments including Laetigen skin booster are deferred during pregnancy and breastfeeding as a precaution at RE:BERRY Gangnam. While PDRN has no documented systemic absorption risks, the clinic follows conservative medical guidelines for all expecting patients.
