Two Frequencies Are Not a Facelift
Xerf is a Korean radiofrequency device that adds 2 MHz to the usual 6.78 MHz. What the second frequency changes, what the small studies show, and how a Seoul shot quote is built.


Face
A Thread Isn’t A Facelift.
A thread lift price from Seoul is often real and still not a facelift. The number hides the thread, the count, and the month it stops holding.
The number that gets you to book a thread lift is rarely the number that holds your face.
Search "thread lift Korea cost" and a desk will send a figure that looks like a decision. A non-surgical lift at a fraction of a facelift. The figure is often real. It is almost never the same operation as the facelift it is being compared with. A thread pulls tissue along a suture for a while. A facelift moves a deeper layer and takes skin. People do not overpay the thread in the operating room. They overpay the comparison.
If you remember one rule, remember this. A thread price without the count is not a price. Six threads and twenty threads are different procedures, different weekends, and different faces.

A thread lift places dissolvable sutures under the skin to shift tissue and, on some products, to stir collagen while they dissolve. PDO, PLLA, and PCL are the families you will see on Korean menus. Mint, Ultra V, and a dozen other names are brands inside those families. Asking for the brand and asking for a lifted jaw are different requests.
The material sets a clock, not a result. PDO is usually absorbed in about six to eight months, PLLA in about a year, PCL in about a year to a year and a half.1 A slower thread costs more. It is not a longer lift. Mint, the name on most Seoul tiles, is a barbed PDO thread from the Korean maker HansBiomed, cleared by the US FDA for face suspension, to hold the cheek tissue temporarily in a lifted position.2 The clearance is about the device. It says nothing about how long your jaw holds.
The lift you feel in the chair is the pull. The lift you still have next year is whatever collagen that pull left behind, plus the fact that you did not gain weight and your tissues did not slide back. Threads do not stop time. A desk that calls them a facelift is selling a feeling.
A Seoul thread quote is set by count, area and material. A visitor consult fee and touch-ups are often extra. As of October 2026, the VAT refund for foreign visitors' cosmetic procedures has ended; it covered treatment received by 31 December 2025.6, 7 Each clinic must display non-covered fees, add them to any website it runs, and charge no more.8, 9
Bills to restore the refund are pending in a National Assembly committee; none had passed by our check on 21 October 2026.10 We have not found a dated, attributable source for Seoul thread prices, so this guide does not print a won or dollar range. What moves the bill is clear enough. A low tile is often a small count in a small area. A higher one is more threads, a named brand, and a face rather than a jawline only. The material sets how long the thread stays, which is not how long the lift stays:
| Thread material | Usually absorbed in about1 |
|---|---|
| PDO (including molded cogs such as Mint) | Six to eight months |
| PLLA | About a year |
| PCL | About a year to a year and a half |
In most studies the visible lift is shorter than any of those numbers.3, 5
Many menus price by the line, so the tile is a unit price, not a plan. Do the arithmetic before the consult. A four-line tile that becomes eight lines in the room has doubled without anyone lying.
A US quote for "thread lift" is often higher for a similar count. The comparison that misleads is the one against a surgical facelift. Those are not two prices for one operation. They are two operations.
What the first number leaves out: the count, the area, whether the threads are cogged or smooth, the consult fee for a visitor, and the touch-up someone offers at eight weeks. A promotion that looks half price is often half the threads.
VAT is the quiet line. Many menus still list VAT separately. Ask whether the won figure already includes it.
If the pinch test on your jaw and neck comes away with spare skin, a thread will not spend that skin. It can sharpen a mild slide. It cannot do the job of a deep-plane or SMAS lift. Booking it because the facelift quote scared you is how people pay twice: once for the thread, later for the operation they needed.
Age is a weak sorter. A 40-year-old with a heavy neck can be a poor thread case. A 55-year-old with mild slide and elastic skin can be a fair one. The mirror is the test. The birthday is not.
A quicker version of that test: put two fingertips just in front of your ears and push the skin up and back by about the width of a pencil. If that small move gives you the face you wanted, a thread is in the conversation. If you need your whole palm, or the neck still hangs, you are describing a facelift, and a thread only rents a few months of it.
Age matters more for the risk than for the result. In a pooled review of 26 studies, patients over 50 had more dimpling, about 16 percent against about 6 percent, and more infection.4
Threads are not a lunch, even when the appointment is short. Dimples, puckering, and a tight smile are common in the first days. Most of that settles over one to two weeks. You can often fly sooner than after a facelift. You should not book a photoshoot for the next morning. The result people judge is the one still there at three months, not the pull they saw in the clinic mirror.
The common side effects are ordinary, not rare. In one study of lower-face threads, about four in five patients bruised, for about four days on average, and soreness averaged about 4 out of 10 for about three days.3 The same pooled review put swelling at about 35 percent, dimpling about 10, numbness or tingling about 6, a thread you can see or feel about 4, and infection or a thread working its way out about 2 each.4 Most dimples settle within about a week. A hard lump or spreading redness is a call to the doctor, not the group chat.
Threads dissolve. Many people talk about a useful change for six to eighteen months, then a softer face. Anyone who promises a surgical timeline for a suture is talking past the product.
The studies are less generous than the ads. In a blinded study of absorbable barbed threads, reviewers saw a mild lift up to three months, and 56 percent of patients showed no lift at twelve months compared with where they started.3 A systematic review found very limited durability in nearly every study it included, and the two positive ones were funded by thread makers.5 Swelling flatters every fresh thread face. If you like the result, price it as maintenance, not as a one-time fix.
Send the complaint, not the product. "My lower cheeks have dropped a little and I want a cleaner jawline" can be assessed. "Mint lift" cannot.
Then ask three things the tile never answers. Who places the threads, by name. What happens if a dimple or a pulled line shows up on day three. Who sees you while you are still in Seoul. Book the threads early in the trip, so the check happens before the flight, not after it.
Yes, it is another name for the same procedure: dissolvable threads placed under the skin to shift tissue. It has nothing to do with threading, the brow hair removal done with cotton thread. Everything in this guide applies.
No. A thread shifts tissue along a suture. A facelift repositions a deeper layer and removes skin. The nickname is the sales tool.
Price follows count, brand, and area. A jaw-only promotion with a few lines and a full face with a named cog are different bills. Ask for the count and the total in won. Not a Peep quote. We have not found a dated source for Seoul thread prices that we would stand behind, so we do not print a range.
Count, brand, area, and whether a visitor fee is inside the number. Six threads are not twenty threads with a smaller font.
Often talked about as six to eighteen months of visible change. The independent studies are shorter. In one blinded study, 56 percent of patients showed no lift at twelve months.3 The suture dissolves. Collagen, if it shows up, is not a guarantee of the same face next year.
The appointment uses local anesthetic. Soreness, tightness, and odd smiles for several days are common. That is not a complication by itself. Asymmetry that stays is a reason to go back.
Many people do. Swelling and puckering are why a next-day flight is a gamble if you have meetings. Ask the desk for their own flight rule.
A thread with barbs that grip tissue. Smooth threads are a different job, often more about texture than shift. The quote should say which.
Mint is a brand, not a result. It is a barbed PDO thread made in Korea by HansBiomed, and the US FDA cleared it to hold the cheek tissue temporarily in a lifted position.2 The count, the direction, and the face matter more than the logo on the box.
They can sharpen a mild slide. A fat pad under the chin is a different tool. A heavy neck with spare skin is closer to surgery.
Tell the clinic. Early puckering often settles. A thread that is visible or painful after two weeks needs a look, not a filter.
Some desks do. Swelling then belongs to both, and you cannot tell which one you dislike. Spacing them makes the bill clearer and the blame clearer.
Often yes, after the threads have settled or dissolved. Tell the next surgeon. Old threads change the tissue they feel.
Very loose skin, a heavy neck, an expectation of a surgical jawline, or a flight that cannot absorb a week of puckering. Pregnancy, an active skin infection on the face, and a history of keloid scars are reasons to wait or skip. Anyone on blood thinners needs a doctor's plan first.
Yes. Counts often run higher. The goal is usually that a colleague cannot tell.
Brand, material, count, areas, whether a touch-up is included, and the fee in won. "Thread lift, full face" is not a list.
A hard pull in week one is common and not the result. A pull that still looks like strings at a month is a reason to be seen.
No. Devices heat tissue. Threads move it. Some people do both. They are separate bills. Order matters too. Many doctors run the device first, or wait some weeks after the threads, because heat and fresh threads are an awkward pair.
Not always. It is often fewer threads. Compare the count before you call it a deal.
Only if your skin still matches what a thread can hold. Using it as a cheaper facelift is the expensive way to delay the operation.
It dissolves more slowly. PDO usually goes in about six to eight months, PLLA in about a year, PCL in about a year to a year and a half.1 In most studies the visible lift is shorter than any of those numbers. The slower thread is a higher price, not a promise of a longer lift.
Partly. A misplaced or poking thread can often be taken out, especially early. Once tissue has grown around the barbs, removing a whole thread is harder. The rest dissolves on its own. Waiting is often the honest answer.
Rubbing, facial massage, and hard pressure on the face. In one study, patients were told to skip high-impact sport for a week, and dental work, saunas, massage, and heat on the area for at least a month.3 Book the dentist around the threads.
The appointment is about an hour. Four to seven days after it lets the clinic see you once any dimple or pulled line shows. If threads are the only reason for the trip, the flight is the expensive part.
They can soften the shadow a little when a cheek that slid down is deepening the fold. They do not add volume or erase a deep crease. Lost volume is a filler question. Loose skin is a surgical one. Ask which one you have before you buy lines for it.
