Rejuran I Eye Treatment Korea: The Complete International Patient Guide
The delicate skin around the eyes is often the first area to show signs of aging, fatigue, and environmental stress. For international patients traveling to Korea for aesthetic treatments, Rejuran I eye treatment has emerged as one of the most sought-after procedures for addressing under-eye concerns with minimal downtime and long-lasting results. This comprehensive guide covers everything you need to know before booking your appointment in Seoul.
What Is Rejuran I Eye Treatment?
Rejuran I (also written as Rejuran Eye) is a specialized formulation of polynucleotide (PN) therapy developed specifically for the periorbital — or eye — area. Unlike the standard Rejuran Healer used on other facial zones, Rejuran I features a lower viscosity and a more refined PN concentration designed to be safely injected into the ultra-thin skin beneath and around the eyes.
The “I” in Rejuran I stands for “eye,” reflecting its targeted application. The active ingredient is salmon-derived DNA fragments (polynucleotides), which stimulate fibroblast activity, promote collagen synthesis, and improve skin elasticity at a cellular level. Clinical studies published in the Journal of Cosmetic Dermatology have shown that PN-based treatments can increase dermal thickness by up to 20% over a 12-week treatment period.
How Rejuran I Differs from Standard Rejuran Healer
Many patients ask why they cannot simply use regular Rejuran Healer around the eyes. The answer lies in the molecular weight and viscosity of the formulation. Standard Rejuran Healer has a higher viscosity that can cause puffiness or lumps when injected into the thinner, more delicate periorbital skin. Rejuran I is specifically engineered to flow smoothly beneath eye-area skin, reducing the risk of complications while maximizing regenerative benefits.
Key Benefits of Rejuran I Eye Treatment
Patients who undergo Rejuran I eye treatment in Korea typically report the following improvements:
- Reduction in dark circles: By improving microcirculation and skin thickness, Rejuran I can minimize the appearance of vascular dark circles over time.
- Decreased fine lines and wrinkles: Crow’s feet and under-eye creases visibly soften as collagen production increases across a treatment series.
- Improved skin hydration: The PN molecules attract and retain moisture within the dermis, creating a plumper, more hydrated appearance.
- Reduced under-eye hollowness: Skin thickening from collagen stimulation can subtly fill mild tear trough depressions without the use of hyaluronic acid fillers.
- Overall skin tone evenness: Patients often notice that the skin around the eyes looks brighter and more uniform in texture after completing a full course of treatment.
Who Is the Ideal Candidate?
Rejuran I eye treatment is suitable for adults in their late 20s and older who experience any of the following concerns:
- Under-eye dark circles caused by thin or translucent skin
- Fine lines and early wrinkles in the periorbital area
- Tired-looking eyes due to skin laxity and loss of elasticity
- Mild under-eye puffiness combined with hollowness
- General skin aging around the eye contour
The treatment is not recommended for patients who are pregnant or breastfeeding, have active infections or inflammation in the treatment area, or have known allergies to salmon or fish-derived products. A thorough consultation with a Korean dermatologist will confirm your suitability before the procedure begins.
What to Expect During the Procedure
Step-by-Step Treatment Process
The procedure at a reputable Korean clinic typically follows this sequence:
1. Consultation and skin analysis: Your dermatologist will assess the periorbital area using high-magnification imaging to determine skin thickness, pigmentation patterns, and the degree of collagen loss. This step ensures a personalized injection plan.
2. Topical anesthesia: A numbing cream is applied to the eye area and left for 20–30 minutes. Most patients find the procedure very tolerable after adequate numbing.
3. Micro-injection technique: Using a very fine 32G or 33G needle, the dermatologist performs papule injections across the under-eye region. Each session typically involves 20–40 small injection points per eye. The entire injection process takes approximately 10–15 minutes.
4. Post-treatment care: A soothing serum or cooling mask is applied immediately after the procedure. Your clinician will provide detailed aftercare instructions before you leave the clinic.
Recommended Treatment Schedule
Most Korean dermatologists recommend a series of 3–4 sessions spaced 2–4 weeks apart for optimal results. Maintenance sessions every 3–6 months help sustain the collagen-building effects long-term. Dr. Kim Hyun-jung, a board-certified dermatologist at a leading Seoul aesthetic clinic, states: “Patients who complete the full initial series of Rejuran I treatments and follow up with biannual maintenance show remarkable long-term improvement in periorbital skin quality compared to single-session recipients.”
Rejuran I Eye Treatment Cost in Korea
One of the primary reasons international patients travel to Korea for this procedure is cost-effectiveness without any compromise in quality. Here is a general price breakdown:
- Single session (both eyes): ₩150,000 – ₩300,000 (approximately USD $110 – $220)
- Package of 4 sessions: ₩500,000 – ₩1,000,000 (approximately USD $370 – $740)
- Combined Rejuran I + Rejuran Healer package: ₩700,000 – ₩1,400,000 (approximately USD $515 – $1,025)
Prices vary depending on the clinic’s reputation, the doctor’s experience level, and the specific Seoul district (Gangnam-based clinics typically charge at the higher end of the range). For comparison, equivalent treatments in the United States and United Kingdom can cost 2–3 times these amounts.
Downtime and Recovery
One of the most appealing aspects of Rejuran I for busy international travelers is its minimal downtime. Most patients experience minor redness and small bumps at injection sites that resolve within 24–48 hours. Slight bruising is possible around the sensitive eye area and may take up to 5–7 days to fade. You can typically resume normal activities, including wearing makeup, within 24 hours of treatment.
Korean dermatologists advise avoiding intense physical exercise, saunas, and alcohol for 24–48 hours post-treatment. Sun protection with SPF 50 is strongly recommended during the healing period.
Why Choose Korea for Rejuran I Eye Treatment?
Korea is the birthplace of Rejuran technology. The product is manufactured by PHAROS, a Korean biotechnology company, and Korean dermatologists have administered the highest volume of Rejuran treatments globally. As of 2025, Korean aesthetic clinics perform an estimated 500,000+ Rejuran-related procedures annually, giving practitioners unparalleled experience with this specific technology.
Additionally, Korea’s competitive medical aesthetics market ensures rigorous quality standards and continuous innovation in injection techniques. International patients also benefit from English-speaking consultation services at major Seoul clinics, as well as transparent pricing structures that are increasingly accessible through clinic websites and medical tourism platforms.
