The first 72 hours of a salmon dna injection korea trip, from the chair to the gate

When people search "salmon dna injection korea", they almost always mean Rejuran Healer, PharmaResearch's polynucleotide (PN) skin booster. The visible part of its recovery is short: small bumps at the injection points usually settle in about 1–3 days. Results and recovery vary from person to person. The worry behind most of these searches is the flight home: will those bumps still be on your face at the departure gate? For most trips, the answer comes down to which day of the week you land.

Time Return Clinic in Yeouido, Seoul, is a Rejuran SVIP clinic selected by PharmaResearch. For Rejuran, the director handles everything from consultation to injection and injects by hand, with our plasma 5-step anesthesia (5A+).

Before you buy a ticket, message us with your main skin concern (fine lines, rough texture, thin skin under the eyes) and the dates you could be in Seoul. We reply with available times, so you can build the flight around a confirmed slot.

Book the appointment before the flight

The clinic is open Mon–Fri 10:00–20:00 and Sat 10:00–16:00, and closed on Sundays and public holidays. A weekend trip that lands Saturday evening and leaves Monday morning has no clinic hours in it. For a salmon dna injection korea trip, check your dates against those hours and the Korean holiday calendar before anything else.

Getting to Yeouido is the easy part. From Gimpo Airport, Line 9 runs to Yeouido Station, and the clinic is about 4 minutes on foot from Exit 4. From Incheon Airport, limousine bus 6007 stops at Eugene Investment & Securities (behind Conrad Hotel), about a 5-minute walk away. The stop for limousine buses back to Incheon Airport is right in front of the clinic.

What is actually inside a salmon DNA injection?

PN, short for polynucleotide, is a chain of DNA fragments purified from salmon and injected into the dermis. PDRN comes from the same source but uses shorter fragments. A review in Pharmaceutics compares how the two are thought to act on skin.

In laboratory studies, PN is linked to more active fibroblasts, the cells in the dermis that make collagen and elastin. The human evidence is thinner. A systematic review of polynucleotides in aesthetic medicine in the Journal of Cosmetic Dermatology reported encouraging findings for skin quality, with side effects that were mostly mild and short-lived. The authors also called for larger controlled trials.

You may see a "salmon facial" or "salmon sperm facial" on social media. When the product only goes on the surface, it works differently. Intact skin keeps out most molecules much larger than about 500 daltons, as Bos and Meinardi described in Experimental Dermatology. PN chains are far larger than that, which is why the clinical product goes in by needle.

Time Return uses four Rejuran products from PharmaResearch, and the doctor chooses which one, or which combination, after assessing your skin. Rejuran Healer is for overall texture, elasticity and fine lines. A version with hyaluronic acid is often chosen for dry skin, and there is one for the eye area and one for acne scars. If the menu names confuse you, read which of Rejuran HB and Rejuran Healer to ask for and what the S, I and H letters mean.

Day 0: consultation, numbing, then many small injections

Injection day has three parts: a face-to-face consultation, numbing and the injections. The director examines your skin and explains the plan. Then you choose a numbing level from 0+ to 5+ on plasma 5-step anesthesia (5A+). Level 0+ equals standard numbing cream.

Rejuran isn't a single shot. It is many tiny injections spread across the area. The doctor injects by hand and adjusts depth point by point, aiming for the dermis, which sits roughly 0.5–2 mm below the surface depending on the area. Each point leaves a small raised bump while the product settles. Why hand injection suits thin skin covers the technique in more detail.

Keep the evening light. Skip the hotel sauna, steam room, hot bath and gym.

How do days 1 to 3 usually look?

For most people the bumps are the main visible sign, and they usually flatten within about 1–3 days. Mild redness usually fades within about 1–2 days. Light makeup is fine from 24 hours, so day 1 can already be an ordinary day out in the city.

Alcohol and smoking are on the avoid list for 1–2 weeks, and that includes the drink on the flight home. Results vary by individual. Some skin still shows bumps on day 3, and some is flat by the next morning. For the weeks after you land, see the Rejuran downtime timeline.

How many nights should you book in Seoul?

For a salmon dna injection korea trip, three nights is a comfortable minimum: one night to arrive, the injection day, and at least one full day for bumps to settle before you fly. Two nights can work if you don't mind visible bumps on the plane.

A four-night version

Land at Gimpo on Thursday evening and take Line 9 to Yeouido. On Friday you have the consultation and injection, with clinic hours running to 20:00. On Saturday redness is usually fading, and light makeup is allowed. On Sunday the clinic is closed and the bumps are usually settling. On Monday you fly home with time to spare.

A two-night version

Land early on Friday, have the injection on Friday afternoon and fly on Sunday. That gives the bumps about two days. Many people find that enough, but some don't. Skip this version if Monday holds a presentation or a photo you care about. Saturday slots end at 16:00, so a Saturday injection squeezes the same plan even tighter.

Doctor's note

I would rather you add one spare day to the trip than ask for a lighter session because the flight is tomorrow. Depth is chosen point by point for your skin, and a departure time is a poor reason to change it. Bumps still showing on day 2 are a common, short-lived reaction, and they are far easier to live with in a hotel than in a meeting.

Send your landing and departure dates on WhatsApp, and tell us whether this would be your first Rejuran. We reply with the available times inside that window, so you can see which of the two calendars works before you commit to a flight.

What are the risks, and which signs are not the usual bumps?

Any injection can cause bleeding, infection, inflammation, swelling or redness. With PN, the expected reactions are the small bumps and mild redness described above, and the systematic review mentioned earlier describes side effects as mostly mild and transient. Serious complications are uncommon, but they do happen, so learn what they look like before you board the plane.

Doctors commonly postpone injectable skin treatments during pregnancy, with an active skin infection or cold sore near the area, or soon after another procedure on the same spot. PN is made from fish DNA, so mention any fish allergy, or any past reaction to a skin booster, at the consultation. Whether Rejuran suits your skin, and which product, is decided at the in-person consultation.

Before you travel, the CDC's medical tourism guidance suggests getting copies of your records and arranging follow-up care at home. For a skin booster, that can be as simple as noting the product name and the date, and knowing which local doctor you would call.

Doctor's note

The bumps are expected, but a few other signs are not. Redness that spreads after the second day, skin that feels hot, pain that grows instead of fading, or any discharge are reasons to see a doctor at home promptly, not to wait it out. Ask for the name of the product used before you leave Seoul and bring it to that appointment, and message us on WhatsApp as well.

Planning the next session from home

The aftercare guidance you get at the clinic includes a suggestion for your next session. The doctor sets the number and spacing of sessions after examining your skin thickness and goals, and we don't promise a fixed number before that assessment. So the second trip is easier to plan than the first, because you already know how your skin behaved on days 1 to 3.

How long a result holds is covered in how long Rejuran lasts. If your main concern is under the eyes, read what Rejuran can and can't do for thin under-eye skin before you choose dates. If you're still deciding which areas to ask about, see the full face, neck or lips guide.

If you're mapping out a salmon dna injection korea visit now, open WhatsApp and send your skin concern with the window you could fly. If you already know the area, such as under the eyes or the full face and neck, add that too. We reply with available times, and you can book the flight around a real slot.
