Clinical Evidence and Documented Results
Rejuran healer contains polynucleotides (PN) extracted from salmon DNA, which stimulate fibroblast activity and promote collagen synthesis at the cellular level. Published research in the Journal of Cosmetic Dermatology documented a 35% improvement in skin elasticity and 28% increase in dermal density after three treatment sessions spaced two weeks apart. Korean dermatology clinics have accumulated extensive clinical data showing consistent outcomes across diverse patient demographics. Discover /p>
Objective measurements using cutometer devices demonstrate quantifiable changes in skin mechanical properties. Studies published in PubMed show polynucleotide injections significantly increase skin hydration levels by 42% and reduce transepidermal water loss by 31% compared to baseline measurements. These aren’t subjective assessments—Korean clinics typically perform before-and-after measurements using standardized equipment, providing patients with documented evidence of improvement.

Key clinical outcomes observed in Korean practices include:
- Reduction in fine lines and superficial wrinkles (measurable within 3-4 weeks)
- Improved skin texture and reduced pore appearance (noticeable at 2-3 weeks)
- Enhanced skin elasticity and firmness (progressive improvement over 8-12 weeks)
- Increased dermal thickness on ultrasound imaging (documented at 2-3 months)
- Reduction in acne scarring depth (gradual improvement over 3-6 months)
- Evening of skin tone and reduced pigmentation irregularities
The Korea Association of Medical Societies (KAMS) recognizes Rejuran as a biological regenerative treatment with established safety profiles. Korean clinics regulated by the Ministry of Health and Welfare (MOHW) maintain treatment protocols that optimize results while minimizing adverse reactions. Board-certified dermatologists in Seoul typically customize injection depths, volumes, and spacing based on individual skin assessment rather than applying uniform protocols.
Response rates vary by treatment indication. For fine line reduction, approximately 85% of patients report visible improvement by week four. For acne scar treatment, improvement rates range from 60-75% with more pronounced results requiring 4-6 sessions. Skin hydration improvements show the fastest response, with patients often noticing a “glow” effect within 7-10 days as dermal water retention increases.
Results Timeline: What to Expect Week by Week
Understanding the progressive nature of Rejuran results helps international patients plan their Korea visit and manage expectations. Unlike dermal fillers that provide immediate volume, Rejuran works through biological processes that unfold over weeks and months. Korean clinics provide detailed timeline information to help patients understand when specific changes become visible.
Week 1-2: Initial Phase
Immediately post-treatment, patients experience injection-related swelling, papules, and mild erythema that typically resolve within 24-48 hours. Some Korean clinics apply LED therapy or cooling masks post-procedure to accelerate recovery. The first visible change most patients notice is improved hydration—skin appears plumper and more luminous as polynucleotides begin attracting moisture to the dermis. This “glass skin” effect becomes apparent around days 7-10.
During this phase, cellular-level changes are already occurring even though major structural improvements aren’t yet visible. Fibroblasts are activated, and anti-inflammatory processes reduce chronic dermal inflammation that contributes to aging appearance. Read about top english speaking dermatologist seoul.
Week 3-4: Early Visible Results
Most patients begin noticing tangible improvements between weeks three and four. Fine surface lines soften as dermal density increases. Skin texture feels smoother to touch, and makeup application becomes easier. Pore appearance diminishes as dermal support structures strengthen. Korean clinics typically schedule the second treatment session during this window to build upon initial results.
Photographic comparisons at one month show measurable differences in skin radiance and texture uniformity. These changes reflect increased collagen production and improved dermal architecture rather than temporary plumping effects.
Month 2-3: Progressive Improvement
The second and third months demonstrate the most dramatic transformation. Skin elasticity improvements become pronounced—patients report that skin “bounces back” when pressed. Deeper wrinkles begin softening as new collagen fills dermal deficiencies. For acne scar treatment, shadowing and depth reduction become noticeable during this phase.
Korean dermatologists often perform the third treatment session around week six to eight, maximizing cumulative regenerative effects. Ultrasound imaging during this period typically shows measurable increases in dermal thickness, confirming biological remodeling is occurring.
Month 4-6: Peak Results and Stabilization
Peak visible results typically manifest between months four and six post-initial treatment. Collagen remodeling reaches optimal levels, providing sustained improvements in skin quality. Wrinkle depth measurements show maximum reduction during this window. Skin maintains improved hydration levels even as direct effects of injected polynucleotides diminish, indicating successful stimulation of endogenous regenerative processes.
Results plateau during this phase but remain stable for 6-12 months in most patients. Korean clinics recommend maintenance treatments every 6-9 months to sustain optimal outcomes, though some patients maintain improvements for over a year from a single treatment series.
Factors Influencing Treatment Outcomes
Results variability depends on multiple patient-specific and treatment-related factors. Korean clinics assess these variables during initial consultation to provide realistic outcome predictions and customize treatment protocols accordingly. Read about gangnam dermatology review.
Age and Baseline Skin Condition
Patients in their late 20s to early 40s with preventive aging concerns typically achieve the most dramatic visible results. Their fibroblasts respond robustly to polynucleotide stimulation, producing new collagen efficiently. Older patients (50s-60s) still benefit significantly but may require additional treatment sessions or combination approaches with other modalities to achieve comparable outcomes. Severely photodamaged skin or advanced dermal atrophy may show more modest improvements requiring extended treatment protocols.
Treatment Protocol Variations
Korean dermatologists vary injection techniques, depths, volumes, and session spacing based on treatment goals. Standard protocols use 2ml per session with 32-gauge needles, creating multiple small papules across treatment areas. Some clinics use cannula techniques for sensitive areas or deeper dermal injection for volume-deficient zones. The number of treatment sessions significantly impacts results—while single treatments provide measurable benefits, protocols using 3-4 sessions spaced 2-4 weeks apart deliver optimal outcomes in clinical studies. Read about top seoul dermatology.
Injection depth matters considerably. Superficial intradermal injections (0.5-1mm) target fine lines and skin texture, while deeper dermal injections (2-3mm) address volume loss and deeper wrinkles. Board-certified Korean dermatologists adjust technique based on real-time skin response during injection.
Lifestyle and Post-Treatment Care
Patient compliance with post-treatment guidelines influences outcome quality. Korean clinics provide detailed aftercare instructions including sun protection, hydration requirements, and activity restrictions. Smoking significantly impairs results by reducing dermal oxygen perfusion and inhibiting collagen synthesis. Adequate hydration, quality sleep, and proper nutrition support the regenerative processes Rejuran initiates.
International patients should avoid intensive sun exposure, harsh chemical peels, and aggressive mechanical exfoliation for 2-3 weeks post-treatment to optimize healing conditions. Many Seoul clinics provide comprehensive skincare protocols including specific product recommendations to enhance and prolong results.
Combination Treatments
Korean aesthetic medicine frequently combines Rejuran with complementary treatments to amplify results. Common combinations include Rejuran with laser treatments, skin boosters containing hyaluronic acid, or micro-needling procedures. These combinations address multiple aging mechanisms simultaneously—Rejuran provides biological regeneration while other modalities target pigmentation, vascularity, or immediate hydration.
Combination protocols typically produce superior outcomes compared to monotherapy, though treatment sequencing and timing require careful planning by experienced practitioners. Most Korean clinics space different treatments by 2-4 weeks to avoid overwhelming skin and allow proper healing between procedures. Read about best seoul skin clinic.
Rejuran Variations and Comparative Results
Korea offers several Rejuran formulations, each designed for specific concerns and anatomical areas. Understanding differences helps patients select appropriate treatments and anticipate outcome variations.
Rejuran Healer (Classic)
The original Rejuran healer remains the most commonly administered formulation, suitable for overall skin quality improvement across face, neck, and hands. It contains 2% polynucleotides in a 2ml syringe. Results focus on comprehensive skin rejuvenation—texture improvement, elasticity enhancement, and gradual wrinkle reduction. Clinical outcomes show 30-40% improvement in overall skin quality metrics after standard three-session protocols.
Rejuran I (Periorbital)
Rejuran I contains lower viscosity formulation specifically designed for delicate periorbital skin. It addresses under-eye hollowing, fine crepey lines, and dark circles caused by thin dermis. Results include subtle volumization, improved skin thickness, and reduced shadowing. Korean ophthalmologic dermatologists perform these injections given the sensitive anatomy. Patients typically notice 20-30% reduction in fine periorbital lines and improved under-eye texture within 4-6 weeks.
Rejuran S (Scarring)
This high-concentration polynucleotide formulation targets atrophic acne scars, surgical scars, and deep wrinkles. It contains higher PN concentration and is injected deeper into dermal defects. Results develop more gradually—significant scar depth reduction typically requires 4-6 monthly sessions. Clinical data shows 40-60% improvement in atrophic scar depth measurements after complete treatment series, though individual response varies considerably based on scar age and severity.
Rejuran Tone-Up
This newer formulation combines polynucleotides with glutathione for dual regeneration and brightening effects. It specifically addresses pigmentation concerns alongside general skin quality. Results include gradual tone evening, reduction in post-inflammatory hyperpigmentation, and the regenerative benefits of standard Rejuran. Brightening effects typically become noticeable at 3-4 weeks, with continued improvement over 2-3 months.
Rejuran HB (High Concentration)
Containing double the polynucleotide concentration of standard Rejuran, HB formulation targets more advanced aging concerns or areas requiring significant regeneration. Korean clinics often reserve this for patients over 45 or those with substantial photodamage. Results are more pronounced but require fewer injection points given higher concentration. Outcome timelines mirror standard Rejuran but with potentially greater magnitude of improvement in elasticity and wrinkle depth.
Comparative studies in Korean dermatology practices show specialized formulations produce 15-25% better outcomes for specific concerns compared to using standard Rejuran for all indications. Board-certified dermatologists assess which formulation or combination best addresses individual patient needs during consultation. Read about gangnam dermatology.
Real Patient Results and Photographic Evidence
Korean clinics maintain extensive before-and-after photographic documentation under standardized lighting and positioning protocols. Reviewing these galleries provides realistic expectations for international patients considering treatment.
Texture and Pore Refinement
Photographic evidence consistently shows visible pore size reduction and overall texture smoothing. Close-up photography reveals more uniform skin surface with reduced irregularities. These changes reflect improved dermal support structures that minimize follicular prominence. Patients with enlarged pores typically see 30-40% apparent reduction after complete treatment protocols, though actual pore size doesn’t change—improved dermal thickness and elasticity creates tighter appearance.
Fine Line and Wrinkle Reduction
Before-and-after images document softening of crow’s feet, forehead lines, and nasolabial creases. Results are moderate rather than dramatic—Rejuran reduces fine line appearance by approximately 30-50% rather than eliminating them entirely. Deeper static wrinkles show improvement but typically require combination approaches with neurotoxins or fillers for optimal correction. Korean clinics emphasize that Rejuran provides natural subtle enhancement rather than dramatic transformation.
Skin Radiance and Hydration
Perhaps the most universally appreciated result is improved skin luminosity and the coveted “glass skin” appearance. Photographic evidence shows enhanced light reflection and more even skin tone. This results from increased dermal water content, improved surface smoothness, and healthier cellular turnover. The radiance effect often appears most dramatic in before-and-after comparisons, even when measured improvements in elasticity or wrinkles are modest.
Scar Improvement Documentation
For acne scar treatment, photographic documentation shows gradual filling and depth reduction over multiple sessions. Rolling scars respond best, with 40-60% depth reduction typical after 4-6 treatments. Ice pick scars show more modest improvement (20-30%) and often require additional procedures like subcision or laser treatments. Korean clinics use cross-polarized photography to document subsurface changes not visible in standard photos. For comparison, see /p>
Realistic Expectations from Evidence
Honest analysis of clinical photography reveals Rejuran provides meaningful but moderate improvements. It won’t replicate surgical results or replace volume lost to aging—instead, it optimizes intrinsic skin quality, creating healthier more resilient tissue. The best candidates are those seeking prevention and gradual quality improvement rather than dramatic transformation. Korean practitioners emphasize this distinction during consultation, ensuring international patients understand realistic outcome potential. Read about top dermatology clinic seoul.
Optimizing and Maintaining Results
Maximizing and prolonging Rejuran outcomes requires strategic planning and proper maintenance protocols. Korean clinics provide comprehensive guidance for international patients to sustain results after returning home.
Initial Treatment Protocol Optimization
Evidence supports completing at least three treatment sessions spaced 2-4 weeks apart for optimal outcomes. Single treatments provide benefits but typically deliver 40-50% less improvement than complete protocols. Korean dermatologists recommend international patients schedule multiple sessions during their visit or plan return trips to complete full series. Some clinics offer concentrated protocols with slightly closer spacing (every 10-14 days) to accommodate international patient schedules, though standard spacing optimizes biological response. Read about Seoul Dermatology Review.
Complementary Skincare Regimens
Post-treatment skincare significantly influences result longevity. Korean clinics recommend medical-grade products containing growth factors, peptides, and antioxidants to support ongoing collagen synthesis. Retinoids enhance cellular turnover and complement regenerative processes, though should be avoided for 1-2 weeks immediately post-treatment. Comprehensive sun protection (SPF 50+ with physical blockers) prevents photodamage that undermines treatment benefits.
Many Seoul clinics create customized Korean skincare protocols for international patients, providing specific product recommendations available for international shipping to support maintenance after returning home.
Maintenance Treatment Schedules
Results typically persist 6-12 months, with gradual diminishment as natural aging processes continue. Korean dermatologists recommend maintenance treatments every 6-9 months to sustain optimal skin quality. Some patients extend intervals to annually with adequate skincare and lifestyle management. Maintenance sessions typically require fewer injections (1-2ml) compared to initial treatment series, making them more convenient for international patients planning periodic Korea visits.
Combination Maintenance Strategies
Long-term skin quality maintenance often involves rotating between different treatments. Korean aesthetic protocols might alternate Rejuran sessions with other skin boosters, laser treatments, or microneedling to address multiple aging mechanisms. This approach prevents treatment fatigue and provides comprehensive anti-aging benefits. Board-certified practitioners create multi-year treatment roadmaps during initial consultation, helping international patients plan periodic Korea visits for maintenance.
Lifestyle Factors for Result Longevity
Patient lifestyle significantly impacts result duration. Smoking accelerates collagen breakdown and should be avoided to preserve benefits. Adequate hydration (2-3 liters daily), quality sleep (7-9 hours), and balanced nutrition rich in antioxidants support continued dermal health. Stress management matters—chronic cortisol elevation promotes collagen degradation. Korean clinics often provide holistic guidance addressing these factors to optimize treatment investment.
Monitoring and Adjustment
Follow-up assessments allow practitioners to evaluate results and adjust future protocols. Korean clinics typically schedule 3-month post-treatment evaluations, reviewing photographic documentation and performing objective measurements. This data informs whether maintenance timing should be adjusted, whether formulation changes would benefit the patient, or whether additional combination treatments would enhance outcomes. International patients can often complete follow-up consultations via telemedicine with photo submissions.
Choosing Korean Clinics for Optimal Results
Not all Rejuran treatments deliver equivalent results—practitioner expertise, product authenticity, and clinic protocols significantly impact outcomes. International patients should evaluate specific factors when selecting Korean providers. Read about skin clinic seoul review.
Board Certification and Specialization
Optimal results come from board-certified dermatologists or plastic surgeons with specialized training in aesthetic injectables. Korean medical licensing through the Ministry of Health and Welfare ensures basic competency, but additional certifications demonstrate advanced expertise. Look for practitioners with KAMS recognition and specific training in polynucleotide therapy. Gangnam and Apgujeong districts
