Rejuran Korea: A Gangnam Doctor's Honest First-Timer's Guide (Cost, PDRN, Before & After)

Rejuran Korea is one of the treatments international patients message me about most — usually after seeing 'rejuran before and after' photos online and wondering whether the glow is real, and how much Rejuran actually costs in Korea. It is real, but not in the way filler ads promise. Let me explain what it actually does, and what you'll realistically pay, before you book anything.

I'm Dr. Hyunji Kim, director at Delphic Clinic in Gangnam. I've treated a lot of skin with Rejuran — locals, tourists on a tight schedule, patients who'd already tried everything. This is the honest first-timer's guide I wish more people read before they fly in.

What Rejuran actually is — in plain language

Rejuran is a series of micro-injections of PDRN — polydeoxyribonucleotide, a purified DNA fragment (from salmon) that signals your skin to repair itself. It's a Korean-developed product (made by PharmaResearch), which is a big reason it's so widely available and reasonably priced here. Think of it as a 'skin healer' rather than a filler. Over a few weeks it supports collagen and elastin, calms inflammation, and improves how your skin behaves: smoother texture, softer fine lines, better elasticity, and that healthy 'lit-from-within' quality people mean by skin quality. There are a few versions — Rejuran Healer (the classic PDRN), Rejuran HB (with added hyaluronic acid for hydration), Rejuran S (for deeper acne scars and specific areas), and Rejuran I for the delicate under-eye.

Here's what Rejuran is NOT: it's not a filler, so it won't add cheek volume or reshape a jawline. It's not a laser, so it won't zap pigment or broken capillaries. And it's not a magic one-session fix. If you want instant, dramatic contour change, Rejuran alone will disappoint you. It's a slow, foundational upgrade to the skin itself. And note — Rejuran creams, masks and turnover ampoules you'll see in Korean pharmacies and stores are supportive skincare, not the same thing as the injectable that delivers PDRN into the skin.

Who Rejuran is really for

Rejuran shines for people whose complaint is skin quality, not shape. In my chair, the best candidates are usually:

• People in their late 20s to 50s who feel their skin looks 'tired,' dull or crepey even with good skincare.
• Those with fine lines, rough texture or enlarged pores who want a natural, no-volume refresh.
• Patients with under-eye crepiness and dark shadows caused by thin, poor-quality skin (Rejuran I is designed for this).
• Anyone recovering from acne who has shallow scarring and uneven texture (often Rejuran S).
• Busy travelers who want a real result with almost no downtime on a short Korea trip.

Who I steer elsewhere: if your main issue is deep folds or lost volume, you want filler. If it's sagging and jawline laxity, we talk about lifting instead. If it's redness, melasma or sun damage, laser or specific pigment treatment comes first. And if you're pregnant, breastfeeding, or have a salmon/fish allergy, Rejuran isn't for you — I'll say so at consultation.

How Rejuran compares — an honest comparison

The question I hear constantly is 'Rejuran vs skin booster vs filler — which one?' They're not really competitors; they fix different things. Here's how I frame it.

In practice I often combine Rejuran with a hydrating booster or careful filler — Rejuran builds the canvas, the others do their specific jobs. It's rarely an either/or.

Before and after: what's realistic

Be honest with yourself about the timeline. Rejuran works on your biology, so you won't walk out transformed. Most patients notice smoother, more hydrated skin around 2–4 weeks after the second session, with texture and fine-line improvement building over the full course. Results are subtle and cumulative — the 'you look well-rested, did you change something?' kind, not the 'you look like a different person' kind. Individual response varies a lot with age, skin condition and how consistent you are. Be wary of dramatic 'before and after' photos online: the honest ones show refined texture and calmer skin, not a reshaped face.

What to expect — step by step

1. 1

   1. Free consultation

   We look at your skin under good light, talk through your goals and history, and I tell you honestly whether Rejuran is right — and which formula. If something else suits you better, I'll say so.

2. 2

   2. Numbing & prep

   We cleanse and apply numbing cream for about 20–30 minutes so the injections are comfortable.

3. 3

   3. The session

   I place a series of tiny PDRN injections across the treatment area. It takes roughly 15–20 minutes. You'll feel small stings — over quickly.

4. 4

   4. Back to your day

   Small bumps settle within a few hours to a day. You can wear light makeup the next day and continue your Seoul plans — it's designed to be one-day friendly.

5. 5

   5. Results build over weeks

   Skin quality improves gradually. We space sessions 2–4 weeks apart, then plan maintenance every 3–6 months.

How we do Rejuran at Delphic — and why it matters

Rejuran is doctor-led here, start to finish. I choose the formula and injection depth for your skin — under-eyes, acne scars and full-face all need a different hand — and I use genuine, properly stored Rejuran product. That last point matters more than people realize: with an injectable this popular, sourcing and technique are exactly where corners get cut. We don't. When you're comparing clinics for 'rejuran korea', ask two questions — is a doctor doing the injections, and is the product genuine and cold-chain stored? At Delphic the answer is yes to both.

How much does Rejuran cost in Korea?

Rejuran cost in Korea depends on the formula and how many cc you need. Because Rejuran is made in Korea, prices here are often well below what you'd pay overseas — one reason so many patients time their course to a Seoul trip. For context, here are our genuine, published prices — the same figures a local Korean patient pays:

Coming from overseas? Here's how we make it easy

We have on-site English and Chinese interpreters, so nothing gets lost between you and me during consultation and treatment. Rejuran is one of the most travel-friendly treatments we offer — low downtime means you can fit a session around sightseeing, and we're a short walk from Sinnonhyeon Station Exit 3. Same price for locals and visitors, always.
