🟢 What it is
Rejuran i in Korea is a specialized form of the Rejuran Healer treatment, developed specifically for the delicate under-eye area. It contains Polynucleotides (PN) derived from salmon DNA, which are highly biocompatible with human skin.
Unlike dermal fillers, Rejuran i does not simply “fill” the hollow. Instead, it repairs and rejuvenates the thin under-eye skin by:
- Stimulating collagen and elastin production.
- Improving skin thickness and elasticity.
- Reducing fine lines and wrinkles.
- Diminishing dark circles caused by thin, fragile skin.
Because the under-eye area is prone to puffiness and vascular issues, Rejuran i is formulated with a lower viscosity compared to regular Rejuran, making it safer and more suitable for sensitive skin.
🟢 Why it’s Done
Patients in Korea choose Rejuran i to address under-eye aging and fatigue-related concerns:
➡️ Thin, fragile skin repair: Strengthens delicate under-eye tissues.
➡️ Fine line reduction: Smooths out wrinkles (“crepey” under-eye skin).
➡️ Dark circle improvement: Reduces shadows caused by thinning skin.
➡️ Hydration & elasticity: Restores youthful firmness and glow.
➡️ Non-filler alternative: Improves under-eye skin without the risk of puffiness from HA fillers.
Korean doctors often recommend Rejuran i for patients who want natural rejuvenation under the eyes, especially those who are not ideal candidates for tear trough fillers.
🟢 Alternatives
While Rejuran i is highly effective, other under-eye treatments may be considered:
🔹 Tear Trough Filler (HA): Adds volume but carries higher risk of puffiness.
🔹 PRP (Platelet-Rich Plasma): Uses growth factors for healing and brightening.
🔹 Skin Boosters (HA, Profhilo): Improve hydration and elasticity.
🔹 Laser treatments (Fraxel, CO2, IPL): Target pigmentation and texture.
🔹 Microneedling with Exosomes: Enhances repair and brightening.
In Korea, Rejuran i is often combined with laser brightening or skin boosters for comprehensive under-eye rejuvenation.
🟢 Preparation
Preparation for Rejuran i helps ensure safety and optimal outcomes:
➡️ Consultation: Doctor examines under-eye hollows, pigmentation, and skin thickness.
➡️ Medical history: Patients disclose allergies, autoimmune conditions, or prior under-eye treatments.
➡️ Avoid blood thinners: No aspirin, ibuprofen, fish oil, or alcohol for 3–5 days.
➡️ Skin care adjustment: Avoid retinoids or harsh peels around the eyes before procedure.
➡️ Expectation setting: Emphasis on gradual improvement, not instant volumizing.
🟢 How it’s Done
The procedure is delicate and takes 15–20 minutes:
- Cleansing & sterilization of the under-eye area.
- Numbing: Topical anesthetic is applied.
- Injection technique:
- Very fine needles or cannulas are used.
- Microinjections of Rejuran i are placed in the dermis under the eyes.
- Special care is taken to avoid bruising or vessel damage.
- Soothing care: Cooling packs or LED light therapy may be applied after treatment.
Korean dermatologists usually recommend a series of 3–4 sessions, spaced 3–4 weeks apart, for best results.
🟢 Recovery
Recovery from Rejuran i is quick, though the under-eye skin is sensitive:
🔹 Downtime: Minimal—patients return to normal activities immediately.
🔹 Redness/swelling: Mild, lasts 1–2 days.
🔹 Tiny bumps: May appear at injection sites, fading within 24–48 hours.
🔹 Results: Gradual improvement over weeks; best results after full treatment course.
✅ Post-care in Korea includes:
- Avoid rubbing or pressing the eyes.
- No alcohol, saunas, or heavy workouts for 24–48 hours.
- Use gentle eye creams and sunscreen.
- Stay well-hydrated to support skin healing.
🟢 Complications
Rejuran i is safe when performed by experts, but mild issues may occur:
⚠️ Mild side effects:
- Redness, swelling, tenderness.
- Small bruises or bumps.
⚠️ Rare risks:
- Infection at injection sites.
- Allergic reaction (very rare due to high biocompatibility).
- Asymmetry if distribution is uneven.
➡️ Korean clinics minimize risks with ultra-fine needles, micro-dosing, and sterile injection protocols.
🟢 Treatment Options in Korea
Korean dermatology clinics offer Rejuran i as part of holistic under-eye rejuvenation programs:
🔹 Stand-alone Rejuran i: Focused on repair, elasticity, and fine lines.
🔹 Rejuran i + Laser Brightening: For patients with pigmentation-driven dark circles.
🔹 Rejuran i + Skin Boosters: Combines hydration (HA boosters) with repair.
🔹 Rejuran i + PRP/Exosomes: Boosts cellular repair for stronger results.
This layered approach is common in Korea, ensuring both skin regeneration and cosmetic improvement.
🟢 Final Thoughts

➡️ Best suited for patients with fragile under-eye skin, fine wrinkles, or dark circles caused by thinning skin.
