Ultherapy is micro-focused ultrasound reaching the SMAS layer, so results depend less on any label and more on how a clinic images, plans depth, and places each of its treatment lines.
To choose a good Ultherapy clinic in Gangnam, Seoul, look for a genuine Ultherapy Prime system with DEEPSEE imaging, a doctor who plans depth and line count for your face, honest talk about a 2 to 3 month timeline, and clear English support. At our Gangnam (Seoul) location, Dr. Yoongon Ryu leads a consultation-based plan, not a fixed menu.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.
Fluent assistance in English, Japanese, and Chinese, making communication clear, respectful and comfortable for international patients.
Over 100,000 patients worldwide have received our personalized dermatological care, highlighting our expertise and reliable results.
Ultherapy is micro-focused ultrasound with visualization (MFU-V) that delivers precise thermal coagulation points down to the SMAS, the deep support layer surgeons address in a facelift, prompting collagen to remodel and gradually lift and tighten. Because the same device can be used well or poorly, the quality of your result depends far more on how a clinic images your tissue, chooses transducer depths, and plans line placement than on any label the clinic gives itself. A good clinic starts with real assessment, not a fixed package.
The most important thing to check is genuine MFU-V with DEEPSEE imaging, which lets the doctor see the layers before delivering energy, plus a treatment plan built around your anatomy. Beware of very low prices that can signal too few lines or a substituted device, since coverage and correct depth are what create a visible lift. An honest clinic also sets realistic expectations: results develop over 2 to 3 months, not overnight.
At Reberry Clinic, Ultherapy care is consultation-led. At our Gangnam (Seoul) location in the Gangnam Station area, Dr. Yoongon Ryu and the clinic’s doctors assess your skin, plan depth and line count, and explain cost transparently, with full English support for international patients across our three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport).
Ultherapy uses micro-focused ultrasound to create tiny thermal coagulation points, typically around 65 degrees Celsius, at set depths without breaking the skin surface. Its DEEPSEE imaging lets the doctor visualise the dermis and the SMAS layer in real time, so energy is placed exactly where it will do the most good and avoids important structures. The deepest transducers reach the SMAS at roughly 4.5mm, while shallower ones target the dermis, and a well-planned session layers 2 or more depths for a fuller effect. Those coagulation points denature collagen and trigger a healing cascade that draws in fibroblasts and builds new collagen and elastin over the following weeks, which is why lifting appears gradually rather than instantly. The correct energy here is focused ultrasound, not radiofrequency or laser, and the number of lines delivered strongly affects coverage and outcome. This is exactly why choosing a clinic with genuine imaging, correct depth planning, and adequate line counts, in experienced hands, matters far more than the label on the door.

Ask whether the clinic uses a real Ultherapy Prime system with DEEPSEE imaging, which lets 1 doctor see the layers before delivering any of the energy points.
Coverage matters, so a full-face plan may involve several hundred lines; a suspiciously low price can mean too few lines and a weaker lift.
A good plan layers 2 or more transducer depths, reaching the SMAS at about 4.5mm plus shallower dermal depths, tailored to your skin and face.
Expect the doctor to explain that lifting builds over 2 to 3 months as collagen remodels, rather than claiming an instant, dramatic overnight result.
A trustworthy clinic sets cost after assessing your face, in English, rather than quoting 1 fixed figure before understanding your coverage needs.

At our Gangnam (Seoul) location, Dr. Yoongon Ryu and the clinic’s doctors assess your skin, plan depth and line count, and explain cost in English.
A full-face Ultherapy session typically takes about 60 to 90 minutes, with DEEPSEE imaging guiding each of the treatment lines delivered.
Many patients need only 1 session per cycle, with a possible touch-up depending on laxity, unlike treatments planned as long series.
Lifting builds gradually over 2 to 3 months as collagen remodels, and your doctor reviews progress and photos at follow-up.
Results often last around a year, and sun protection plus good skincare help; a maintenance session may be planned as skin continues to age.



Choose a clinic that uses genuine Ultherapy Prime with DEEPSEE imaging, where a doctor plans depth and line count for your face and sets honest timelines. An adequate line count matters more than a low price. You can start with our Ultherapy Prime page to see how we approach it.
Ultherapy is provided at our Gangnam (Seoul) location in the Gangnam Station area, where Dr. Yoongon Ryu leads the plan. Care is also available at our Myeongdong and Incheon Airport locations. International patients receive full English support and can schedule their session around travel to Seoul, Korea.
Ultherapy is micro-focused ultrasound (MFU-V) that creates thermal points at set depths down to the SMAS layer, using DEEPSEE imaging to see the tissue first. Those points prompt new collagen so skin gradually lifts. You can compare it with radiofrequency on our Thermage FLX page.
Line count reflects how much coverage and energy your face receives, so too few lines usually means a weaker, less visible lift. A full-face plan can involve several hundred lines depending on your anatomy. This is why a suspiciously low price is a warning sign, and why a doctor plans coverage individually.
Ultherapy can feel like deep, brief pinpoint heat along each treatment line, which most patients tolerate well, especially with comfort measures. Sensation varies by area and depth, and bonier regions feel more. Your doctor at our Gangnam location adjusts settings and pacing to keep the session as comfortable as possible for you.
Downtime is minimal for most people, with possible mild redness, slight swelling, or tenderness that usually settles within hours to a few days. You can generally return to normal activities the same day. Your doctor will advise on gentle aftercare and sun protection while collagen remodeling gets underway.
Lifting develops gradually over about 2 to 3 months as new collagen forms, though some tightening may be felt earlier. Because the change is progressive, results are best judged with follow-up photos rather than immediately after treatment. Your doctor reviews your progress across that window at our Gangnam location.
Results often last around a year, but this is not a one-time fix because skin keeps ageing naturally over time. Many patients plan a maintenance session as the effect softens. Sun protection and consistent skincare help preserve the lift, and your doctor will suggest a realistic maintenance rhythm at consultation.
Many people need only 1 session per cycle, unlike treatments planned as long series, though some with more laxity benefit from a touch-up. Your ideal plan depends on your skin and goals. A doctor confirms this after assessing your face rather than defaulting everyone to the same package.
Ultherapy uses focused ultrasound to reach the deep SMAS for lifting, Thermage FLX uses radiofrequency for broad firming, and Sofwave uses mid-dermis ultrasound for comfortable tightening. The right choice depends on your laxity and goals, which a doctor assesses at consultation.
Yes, Ultherapy is often combined with skin boosters, radiofrequency, or fillers for a fuller, layered result, sequenced so the skin is not over-stressed. For example, it may pair with a collagen-stimulating booster. Your doctor plans the order and spacing so each treatment supports the others safely.
Adults with mild to moderate facial or neck laxity who want a non-surgical lift are often good candidates, while very advanced laxity may be better assessed surgically. A consultation with imaging confirms whether ultrasound suits your tissue. Your doctor will explain honestly if another approach fits your goals better.
Side effects are usually mild and temporary, such as redness, swelling, tenderness, or brief numbness that settles within days. Uncommon effects are minimised when a doctor uses imaging and correct depth. A thorough consultation and honest medical history help keep Ultherapy both effective and safe for your face.
Cost depends mainly on the number of lines and the coverage your face needs, so there is no single fixed figure and very low prices can mean too few lines. At our Gangnam location, the clinic’s doctors explain a transparent cost in English after assessing you. Start on our Ultherapy Prime page.
For Ultherapy, 2 to 3 days in Seoul is comfortable, allowing a consultation, the session, and a short review before you travel. Because results build over months, follow-up can be done remotely. Our English-speaking team helps coordinate the timing around your trip to Seoul, Korea.
Yes, flying within a day or so is generally fine because Ultherapy is non-invasive with minimal downtime. Any mild swelling or tenderness usually settles quickly. Cabin air is drying, so moisturise and protect your skin from sun, and your doctor will provide simple aftercare guidance for the journey home.
Because Ultherapy results develop over 2 to 3 months, follow-up is well suited to remote English check-ins, and the clinic keeps your treatment notes on file for continuity. You can also support your skin at home with a good skin care routine between visits to Seoul.
