What Is Rejuran Face Treatment
Rejuran is an injectable skin rejuvenation treatment utilizing polynucleotides (PN) extracted from salmon DNA. These biological molecules share remarkable compatibility with human DNA, triggering natural regenerative processes within skin tissue. Unlike dermal fillers that add volume or neuromodulators that relax muscles, Rejuran works by stimulating fibroblast activity and promoting collagen synthesis at the dermal level. Discover /p>
The treatment originated in South Korea where it received approval from the Ministry of Food and Drug Safety (MFDS) before gaining international recognition. Korean dermatologists and plastic surgeons have refined injection techniques specifically for Asian and Caucasian skin types over the past decade, making Korea the global center for Rejuran expertise.

Mechanism of Action
Polynucleotides in Rejuran function through multiple pathways. They activate fibroblasts responsible for producing collagen, elastin, and hyaluronic acid—the structural components maintaining skin firmness and hydration. Research published in PubMed demonstrates that PN fragments promote tissue repair by reducing inflammation and supporting cellular regeneration through adenosine receptor stimulation.
The salmon-derived DNA is fragmented into specific molecular weights optimized for dermal absorption and biocompatibility. This purification process removes immunogenic proteins, leaving only the therapeutic nucleotide chains. Once injected into the dermis, these molecules integrate into damaged tissue areas, providing scaffolding for new cell growth while reducing oxidative stress.
Types of Rejuran Products
Korean clinics offer several Rejuran formulations tailored to different facial concerns:. Read about best gangnam skin clinic.
- Rejuran Healer: The original formulation for overall skin rejuvenation, texture improvement, and pore refinement
- Rejuran I (Eye): Lower viscosity formula designed specifically for delicate periorbital skin with shorter needles
- Rejuran S: Concentrated version targeting acne scars, deep wrinkles, and localized texture irregularities
- Rejuran Tone-up Booster: Combines PN with brightening agents for complexion enhancement
- Rejuran HB: Higher concentration product for advanced aging concerns
Each formulation requires different injection depths and techniques, which Korean practitioners have extensively documented through clinical practice. Board-certified dermatologists in Seoul typically assess skin condition and concern-specific needs before recommending appropriate Rejuran variants or combination protocols.
Benefits and Expected Results for Face Rejuvenation
Rejuran face treatments deliver progressive improvements rather than immediate dramatic changes. International patients should understand the timeline and realistic outcomes before traveling to Korea for treatment. Read about korean dermatology.
Primary Benefits
Skin Texture Refinement: Patients typically notice smoother skin texture within 2-3 weeks as polynucleotides stimulate collagen remodeling. Rough patches, uneven surfaces, and enlarged pores gradually diminish over the treatment course.
Hydration Enhancement: Rejuran increases the skin’s moisture-retention capacity by promoting hyaluronic acid production within dermal layers. This results in plumper, more supple skin that maintains hydration longer than topical treatments alone.
Elasticity Improvement: By activating fibroblasts to produce elastin fibers, Rejuran restores lost elasticity associated with aging and environmental damage. Skin becomes more resilient with improved bounce-back quality.
Scar Reduction: Rejuran S specifically targets atrophic acne scars and ice-pick scars through concentrated PN delivery. Studies indicate measurable improvement in scar depth and surface regularity after multiple sessions.
Fine Line Softening: While not replacing neuromodulators, Rejuran softens fine lines by improving underlying skin quality. Periorbital lines, forehead creases, and nasolabial folds appear less pronounced as dermal thickness increases.
Barrier Function Restoration: Polynucleotides strengthen the skin’s protective barrier, reducing sensitivity to environmental irritants and improving overall skin health. This proves particularly beneficial for patients with compromised barriers from over-treatment or environmental factors.
Clinical Evidence
PubMed-indexed research demonstrates significant improvements in skin elasticity, hydration metrics, and patient satisfaction scores following Rejuran treatments. A study measuring transepidermal water loss (TEWL) showed marked barrier function improvement at 4 and 8-week intervals post-treatment.
Korean dermatological literature documents extensive case series with objective measurements using cutometry, corneometry, and clinical photography. These studies consistently show progressive improvement over 3-6 month periods with optimal results achieved through serial treatments.
Realistic Timeline
Week 1-2: Minimal visible changes; initial healing of injection points
Week 3-4: Improved hydration and subtle texture refinement noticeable
Week 6-8: Enhanced elasticity, reduced pore appearance, overall glow
Month 3-6: Cumulative improvements peak; maintenance treatments recommended
International patients should plan follow-up treatments either during extended stays in Korea or coordinate with qualified practitioners in their home countries, though expertise levels vary significantly outside Seoul’s specialized clinics.
Treatment Protocol and Procedure Details
Understanding the actual treatment process helps international patients prepare for their Seoul clinic visits and manage expectations regarding comfort, duration, and immediate post-procedure appearance.
Pre-Treatment Consultation
Korean clinics accredited by the Korean Association of MedicalEsthetics (KAMS) typically conduct thorough skin assessments before Rejuran administration. Consultations include skin type analysis, concern identification, medical history review, and treatment customization. English-speaking coordinators in Gangnam clinics facilitate communication for international patients.
Practitioners evaluate factors including skin thickness, existing damage levels, sensitivity history, and aesthetic goals. Photography documentation establishes baseline conditions for tracking progress. Board-certified dermatologists may recommend combination approaches integrating Rejuran with laser treatments, microneedling, or other modalities for optimized outcomes.
Injection Technique
The procedure employs multiple superficial intradermal injections using fine-gauge needles (typically 32-34G). Korean practitioners utilize specific techniques developed through extensive clinical experience:
Stamping Technique: Multiple point injections across treatment areas at 0.5-1cm intervals, delivering small volumes per injection site. This creates an even distribution pattern across the face.
Nappage Technique: Superficial microinjections into the papillary dermis using very fine needles at 2-4mm depth.
Cross-hatching: For targeted scar treatment with Rejuran S, practitioners inject in perpendicular patterns to maximize coverage of affected areas.
Topical anesthetic cream applied 20-30 minutes before treatment minimizes discomfort, though some patients report mild stinging during injection. The entire face treatment typically takes 20-30 minutes depending on coverage area and technique complexity.
Immediate Post-Treatment
Patients experience immediate papules (small bumps) at injection sites—a normal response that typically resolves within 24-48 hours. Some redness and minor swelling occur, particularly in thinner skin areas like periorbital regions. Korean clinics provide specific aftercare instructions including:
- Avoiding makeup for 6-12 hours post-treatment
- Gentle cleansing without rubbing for 24 hours
- Avoiding intense exercise, saunas, and alcohol for 48 hours
- Applying recommended healing ointments or serums
- Staying hydrated and avoiding sun exposure
Most international patients can resume normal activities the next day, making Rejuran suitable for those with limited time in Seoul. The treatment earns the “lunchtime procedure” designation due to minimal downtime requirements.
Recommended Treatment Schedule
Korean dermatologists typically recommend initial series protocols:
Standard Protocol: 3-4 sessions spaced 3-4 weeks apart for establishing baseline improvement
Intensive Protocol: 4-6 sessions at 2-week intervals for advanced aging or significant scarring
Maintenance Protocol: Single sessions every 3-6 months after initial series completion
International patients often receive multiple sessions during extended Seoul visits or coordinate intensive protocols during medical tourism trips. Some clinics offer package pricing for serial treatments booked in advance.. Read about english speaking dermatologist seoul.

Clinic websites should display clear information about treating physicians, their training backgrounds, years of experience, and specific expertise areas. Before-and-after galleries, while requiring critical evaluation, indicate the clinic’s comfort with outcome transparency.
Social media presence, particularly Instagram and YouTube, often showcases procedural videos, patient testimonials, and educational content that reveals practitioner knowledge depth and communication style. Korean clinics with established international patient programs typically maintain English-language social content.
Consultation Quality Indicators
The initial consultation reveals much about clinic quality and practitioner expertise. Red flags include rushed consultations, pressure tactics for immediate treatment, or reluctance to discuss risks and limitations. Quality consultations involve thorough skin assessment, realistic expectation-setting, and customized treatment planning rather than one-size-fits-all approaches.
Competent practitioners acknowledge when Rejuran may not be the optimal treatment choice and suggest alternatives or combination approaches. They should explain the specific Rejuran formulation recommended, injection technique planned, and realistic timeline for expected results.
English-language communication capability, whether through bilingual physicians or trained medical interpreters, ensures accurate information exchange about medical history, concerns, and post-treatment instructions.
Facility Standards
Visit clinics personally when possible to assess cleanliness, organization, and professional atmosphere. Treatment rooms should demonstrate proper sterilization protocols with single-use needles, sterile technique maintenance, and appropriate medical waste disposal.
Reputable clinics maintain climate-controlled product storage ensuring Rejuran vials remain within manufacturer-specified temperature ranges. They should provide product packaging display confirming authenticity and allow verification of expiration dates.
Gangnam vs. Other Districts
While Gangnam and Apgujeong districts command premium pricing, they concentrate Korea’s most experienced aesthetic practitioners and advanced facilities. These areas developed specifically around medical aesthetics with intense competition driving quality and innovation.
Clinics in areas like Myeongdong or Hongdae may offer lower pricing but often target domestic patients with less English support and potentially less experience with Caucasian skin types. International patients typically find the Gangnam premium worthwhile for expertise, communication, and international patient accommodation. Read about Seoul Dermatology.
Pricing Transparency
Reputable clinics provide clear pricing information upfront with detailed breakdowns of what’s included. Be cautious of significantly below-market pricing which may indicate diluted products, inexperienced practitioners, or upselling schemes.
Package pricing for multiple sessions should offer reasonable discounts (typically 10-20%) compared to single-session rates. Payment policies, cancellation terms, and refund conditions should be clearly explained before treatment commitment.
Safety Considerations and Potential Side Effects
While Rejuran maintains an excellent safety profile, international patients should understand potential risks, contraindications, and appropriate response protocols for any complications.
Common Side Effects
Expected reactions occurring in most patients include injection site papules lasting 24-72 hours, mild erythema resolving within days, and temporary swelling particularly in periorbital areas. These represent normal inflammatory responses rather than complications and typically resolve without intervention.
Some patients experience minor bruising at injection points, particularly those with thinner skin or taking supplements like fish oil that affect clotting. Bruising generally fades within one week and can be concealed with makeup after the initial 12-hour period.
Temporary skin sensitivity or slight tenderness at treatment
