Rejuran Eye vs. Rejuran: Is It Different?
Rejuran Eye isn't a rebrand of regular Rejuran; it's a separate formulation with a lower concentration, thinner texture, and shallower injection depth, built for skin under the eyes that's only about 0.5mm thick.
If you've been told Rejuran Eye is basically just Rejuran for the under-eye area, that's not quite right. It's a separate formulation, and mixing the two up can leave you with lumps that take weeks to settle.
In this article, we'll cover what actually separates Rejuran Eye from regular Rejuran, who tends to be a good candidate, what a typical treatment course looks like, and what it costs at a Seoul clinic.
What Is Rejuran Eye, Exactly?
Rejuran is built around PN, polynucleotides derived from salmon DNA, injected into the skin to encourage the dermis to regenerate and produce more of its own collagen. It's one of the more established skin boosters in Korean dermatology, and it's typically used across the cheeks, forehead, and general face.
Rejuran Eye is a distinct version of that same PN technology, formulated specifically for the skin around the eyes. Same active ingredient family, different formula, and that distinction matters more than it sounds like it should.
How Is Rejuran Eye Different From Regular Rejuran?
Here's the short answer: concentration, viscosity, and injection depth are all dialed back for the eye area, because under-eye skin is roughly 0.5mm thick, among the thinnest skin on your body.
We saw this play out with a patient in her early 40s who came to us after getting regular Rejuran under her eyes at another clinic. Two weeks later, the small bumps at each injection point still hadn't gone down. On exam, the PN hadn't dispersed evenly; it had clumped instead. That's a fairly predictable outcome when a formula meant for thicker skin goes into skin this thin.
| Feature | Regular Rejuran | Rejuran Eye |
|---|---|---|
| PN concentration | Around 2% | Lower, formulated for thin skin |
| Viscosity | Thicker | Thinner, spreads more evenly |
| Typical injection depth | About 1 to 2mm | About 0.3 to 0.5mm, upper dermis |
| Best suited for | Cheeks, forehead, general facial skin | Under-eye area specifically |
That depth difference isn't just a technicality. Going 1 to 2mm deep under the eye starts to approach the orbital septum, the membrane that helps hold fat in place around the eye socket, and that's not where you want a needle going too deep. Rejuran Eye stays shallow, in the upper dermis, on purpose.
So if someone tells you Rejuran "didn't do much" for their under-eye area, there's a good chance they got the regular formula. It's not that Rejuran doesn't work under the eyes; it's that the wrong version was used there.
Who's a Good Candidate for Rejuran Eye?
Rejuran Eye tends to make the most sense for people in the early stages of under-eye aging: fine lines that show up when you smile, skin that feels crepey or dry no matter how much eye cream you layer on, and a general loss of bounce under the eyes.
One thing worth knowing upfront: Rejuran Eye is a texture-and-elasticity treatment, not a wrinkle eraser. If you're dealing with deep, static folds that are there even at rest, Rejuran Eye alone probably won't flatten them. That's usually a job for Botox or filler, sometimes layered alongside Rejuran Eye rather than instead of it.
What to Expect: Sessions, Timeline & Downtime
Most treatment courses run three sessions, spaced three to four weeks apart. Right after each session, you'll likely see small raised bumps at the injection points. That's normal, and for most people it settles within two to four hours. If your skin runs sensitive, it can take closer to a full day.
- Same day: Small bumps and mild puffiness at injection points, usually gone within a few hours.
- Next day: Skin looks normal again. This is also when it's fine to wear makeup as usual.
- Over the course: Texture and tone tend to improve gradually across the three sessions, not all at once.
- Longer term: With consistent treatment, many people also notice their dark circle tone looks a little better, alongside smoother texture.
Side Effects & Risks
The under-eye area is full of small blood vessels, so bruising is one of the more common things to plan around. Roughly 20% to 30% of patients develop a small bruise that can stick around for about a week. If you've got a big event coming up, it's worth booking your session at least two weeks ahead of time.
Beyond bruising, expect some temporary swelling and small bumps at each injection point, as covered above. These are expected parts of the process, not complications. That said, if you notice spreading redness, worsening pain, or swelling that isn't improving after a few days, contact your provider right away.
A full consultation before treatment is the best way to flag anything specific to your skin or medical history. This isn't a one-size-fits-all treatment, and your provider should walk through your case before booking you in.
How Much Does Rejuran Eye Cost?
At our Seoul clinic, Rejuran Eye typically runs somewhere around ₩200,000 to ₩250,000 per session, and most patients book the full three-session package rather than paying session by session. Results tend to hold for roughly six months, though that varies from person to person.

The Bottom Line
Rejuran Eye and regular Rejuran share the same PN technology, but they aren't interchangeable. Rejuran Eye is formulated with a lower concentration, thinner viscosity, and a shallower injection depth built specifically for skin that's only about 0.5mm thick.
- Rejuran Eye is a separate formula from regular Rejuran, not just the same product injected in a new spot.
- It's best for early fine lines, crepey texture, and dullness under the eyes, not deep, static wrinkles.
- Most courses run three sessions, three to four weeks apart, with bruising as the main thing to plan around.
Like any injectable, it comes with trade-offs, and individual results vary. Ultimately, the choice depends on your skin, your goals, and your budget. If you're considering Rejuran Eye, a consultation is the best way to find out what actually fits your under-eye concerns.

Frequently Asked Questions
Q1. Is Rejuran Eye just regular Rejuran injected around the eyes?
No, it's a separate formulation. Regular Rejuran is thicker, more concentrated, and typically injected deeper, which is why using it under the eyes can leave lumps that take weeks to resolve. Rejuran Eye is formulated with a lower concentration, thinner viscosity, and a shallower injection depth built specifically for that thin skin.
Q2. Can I wear makeup right after a Rejuran Eye session?
Same-day makeup usually isn't recommended, since the tiny injection points need time to close. Most people are fine to wear makeup as usual starting the next day.
Q3. How many sessions does Rejuran Eye take, and what does it cost?
Most courses run three sessions, spaced three to four weeks apart. At our Seoul clinic, pricing typically runs around ₩200,000 to ₩250,000 per session, and many patients book the full three-session package. Check /en/promotion for current offers and /en/price for our full list. Seoul clinic pricing, subject to change.
Q4. I bruise easily. Is Rejuran Eye risky for me?
The under-eye area has a lot of small blood vessels, so bruising is common: about 20% to 30% of patients get a small bruise that lasts around a week. If you have an event coming up, plan your session at least two weeks ahead, and talk through your history with your provider beforehand.
