Best Rejuranin Gangnam, Seoul

• Anyone looking up the best Rejuran in Gangnam is really asking which clinic to trust with a polynucleotide injection, so this page sets out 5 Gangnam clinics that offer it and the checks that separate one quote from another.
• Rejuran is a PN (polynucleotide) skin booster made by PharmaResearch, injected as hundreds of tiny points into the upper dermis to support skin repair, texture and fine lines rather than to add volume.
• Clinics price it by the amount of product, usually per cc or per syringe, and quotes are written before VAT, with 10% VAT added at payment.
• The one check worth more than any other: ask to see the sealed box and syringe opened in front of you, and ask how many cc will go into each area.

Rejuran belongs to the PN family of injectables. Its active ingredient is a purified polynucleotide drawn from salmon DNA, at roughly 20 mg per mL. It is not PDRN, a separate ingredient, and it is not a hyaluronic acid filler. Instead of filling, PN is placed in tiny amounts across the face to support repair and moisture over the following weeks. The range includes Healer for the full face, HB Plus with hyaluronic acid and lidocaine, and an i version for thin skin around the eyes.

A session usually starts with a skin assessment and numbing cream for about half an hour. The doctor then places 200 to 300 micro-injections by needle or injector device. Small bumps form at each point and settle within a day or two. The effect is commonly described as lasting around four to six months, with real variation between people.

Evidence is growing but still modest. A 2026 expert perspectives paper by Rho and colleagues in Clinical, Cosmetic and Investigational Dermatology reviewed how polynucleotides are used across aesthetic medicine and dermatology. In a 2026 prospective study in the Journal of Cosmetic Dermatology, Ziade and colleagues followed 42 patients treated with intradermal polynucleotides under the eyes, using a different PN brand, and reported significant improvement in lower eyelid and crow's feet scores at one, three and six months, with the largest gain at three months after two sessions and only minimal side effects.

Rejuran is developed and produced in Korea, so Gangnam clinics handle it every day and stock several product lines rather than a single option.

Bumps usually flatten within a day or two, which lets visitors fit a session into a short stay and still fly home with few visible marks.

Many Gangnam clinics see international patients routinely and explain consent forms and aftercare in English.

Pricing by cc or syringe makes quotes from different clinics easy to line up, as long as each one states the product line and the amount used.

• A good fit: adults with dull texture, enlarged pores, fine crepey lines or thin skin who want gradual change in skin quality.
• A good fit: people who prefer a treatment that adds no visible volume and changes the face slowly over several weeks.
• A good fit: visitors who can stay a few days in Seoul or return for a follow-up.
• Not a good fit: anyone pregnant or breastfeeding, anyone with a fish or salmon allergy, or anyone with an active infection, cold sore or eczema flare on the face.
• Not a good fit: people expecting a lift, a sharper jawline or volume replacement, which call for other treatments.
• Not a good fit: anyone who must look unmarked the next morning.

• Sealed product: the box and syringe should be opened in the room, with the product line and batch visible before the first needle goes in.
• Dose per area: a clear quote names how many cc go to the full face, the eyes or the neck, so you can tell a light session from a full one.
• Who injects: ask whether the doctor places the injections personally or whether another staff member performs the session after the consultation.
• Method and numbing: clinics use hand needles, injector devices or a mix, and the choice affects comfort, bruising and the number of points placed.
• Written aftercare in your language: you should leave with instructions on washing, makeup, sun, alcohol and exercise, plus a way to send photos if something worries you.
• Transparent pricing: the quote should show the price before VAT, the 10% VAT added at payment, and whether numbing, soothing masks or a follow-up visit are included.
• An honest consultation: a careful clinic will say when Rejuran is not the right tool for your concern and suggest a different approach instead.

No single Gangnam clinic suits everyone; the right choice depends on what you want to change and how much time you have. A first-timer may value a doctor who explains the product lines slowly and starts with a lighter amount, while someone on a short trip may care most about bruise control and clear aftercare for the flight home.

If you plan to add a laser or lifting device, ask for the order and spacing in writing. If budget matters most, compare quotes by cc and by what is included, then pick the clinic whose answers are specific and honest about what Rejuran cannot do.
