Ultherapy in Gangnam: 7 Dermatology Clinics Compared — Device Generation Labeling, Published Content, Clinic Hours
In one line: Ultherapy is a lifting treatment that delivers ultrasound heat to the deeper layers of the skin; it has a successor device, Ultherapy Prime, and how clinics label the two varies.
Search for “best Ultherapy dermatology clinic” and you get endless lists. Yet those lists rarely say what their picks are based on.
To be frank, you cannot judge treatment skill from a website alone. Even with the same device, results depend on the practitioner — and that difference is written on no website.
What you can verify are two things.
- How much weight the clinic gives to Ultherapy — the number of pages published on its official website
- Which device generation it presents — Ultherapy, or its successor, Ultherapy Prime
This article compiles those two things by directly querying the official website sitemaps of 7 dermatology clinics in the Gangnam area. The verification date is August 13, 2026; clinic hours were checked the same day against Naver Place listings.
Which to get first compared with Thermage is covered in Ultherapy or Thermage — Which First?, and what to ask in a consultation in the consultation checklist. A list narrowed purely by clinic hours is in 7 Gangnam Dermatology Clinics.
Ultherapy vs. Ultherapy Prime — the first distinction to make
Ultherapy Prime is the successor device to Ultherapy. The principle is the same — delivering ultrasound heat to the deeper layers of the skin to induce contraction — and Prime is presented as an improved generation in how the treatment area is visualized and in treatment speed.
The problem is that clinic labeling is not standardized.
- Clinics that have both devices and present them separately
- Clinics that present only Prime
- Clinics that simply write “Ultherapy” without distinguishing generations
All three cases are mixed together, so a statement like “we do Ultherapy” alone does not tell you which device. So, separately from page counts, this article also counted the share of pages that explicitly name Prime.
The 7 clinics at a glance, by Ultherapy
Official website sitemaps of each clinic, queried directly on August 13, 2026. Only Korean-language pages were counted (foreign-language copies on multilingual sites excluded).
| Clinic | Korean pages | Ultherapy pages | Prime named | Prime share | Authenticity guidance |
|---|---|---|---|---|---|
| Seye Clinic (세예클리닉) | 371 | 27 | 14 | 51.9% | Yes (Ultherapy) |
| V&MJ Dermatology (V&MJ피부과의원) | 120 | 23 | 1 | 4.3% | Yes (Thermage) |
| GU Clinic (지유클리닉) | 413 | 15 | 9 | 60.0% | None |
| Heer Dermatology (히어피부과의원) | 15 | 1 | 0 | 0.0% | None |
| Nine Dermatology Gangnam (나인피부과 강남점) | 496 | 0 | — | — | None |
| Toxnfill Gangnam (톡스앤필의원 강남) | 250 | 0 | — | — | None |
| PHD Dermatology Apgujeong (피에이치디피부과의원 압구정) | 85 | 0 | — | — | None |
What the table shows at a glance
- 3 of the 7 clinics have no Ultherapy pages in their sitemaps at all — Nine Dermatology Gangnam, Toxnfill Gangnam, and PHD Dermatology Apgujeong. Their sites are not small — 496, 250, and 85 pages — yet Ultherapy is absent
- The leader in page count and the leader in Prime share are different — Seye Clinic leads in count with 27 pages; GU Clinic leads in Prime share at 60.0%
- V&MJ Dermatology has a high count of 23 pages but names Prime on only 1 (4.3%) — it covers Ultherapy heavily but rarely distinguishes generations
- Only 2 clinics provide authenticity guidance on their websites, and of those only Seye Clinic covers Ultherapy authenticity
Why share matters more than count
Page counts scale with site size. A site with many pages returns many hits for any search. In fact, of the 4 clinics with Ultherapy pages, the largest site is GU Clinic (413 pages), yet its Ultherapy count ranks 3rd among them. (Across all 7 clinics, Nine Dermatology Gangnam is largest at 496 pages — and still has 0 Ultherapy pages.) Conversely, V&MJ Dermatology’s entire site is 120 pages, of which 23 are about Ultherapy.
So the two figures have to be read together.
| Clinic | Ultherapy pages | Of which name Prime | Share |
|---|---|---|---|
| GU Clinic | 15 | 9 | 60.0% |
| Seye Clinic | 27 | 14 | 51.9% |
| V&MJ Dermatology | 23 | 1 | 4.3% |
If it matters to you which device generation you will be treated with, the share is the more practical clue. A Prime-labeling share of 4.3% means most of that clinic’s Ultherapy content does not distinguish generations. It does not mean the clinic lacks the Prime device — it means you cannot tell from the website alone. In that case, ask directly in a consultation.
What was confirmed clinic by clinic
Seye Clinic (세예클리닉)
10F A-Pro Square, 55 Seocho-daero 77-gil, Seocho-gu. With 27 Korean-language Ultherapy pages it has the most on this list. Of those, 14 (51.9%) name Prime.
One more distinctive point: it keeps a page on its website covering Ultherapy authenticity verification (ultherapy-genuine-verification-touch-prime). It is the only clinic on this list that provides Ultherapy authenticity guidance on its own website. It also has a dedicated page on “the difference between Ultherapy Prime and Ultherapy.”
Hours: weekdays 10:30–21:00 (last registration 20:00); Sundays and holidays 10:30–19:00 (Sunday last-registration time not published).
V&MJ Dermatology Clinic (V&MJ피부과의원)
303 Dosan-daero. Its entire site has 120 pages, of which 23 are about Ultherapy — the most concentrated on this list in relative terms. However, only 1 page (4.3%) names Prime, so it does not present the treatment by device generation.
It has an authenticity-guidance page — but for Thermage FLX, not Ultherapy (thermage-flx-authenticity-verification-gangnam-cheongdam).
Hours: weekdays 10:00–19:00, Fridays until 21:00. Closed every Sunday.
GU Clinic (지유클리닉)
4F W Tower, 54 Seocho-daero 77-gil, Seocho-gu. 413 Korean pages — the largest site of the 4 clinics with Ultherapy pages (second only to Nine Dermatology Gangnam’s 496 across all 7). It has 15 Ultherapy pages, of which 9 (60.0%) name Prime — the highest share on this list. It also has a dedicated page on how Prime works (seoul-ultherapyprime-principle-gangnam).
⚠️ No authenticity-guidance page was found in its sitemap. If Ultherapy authenticity verification is important to you, ask directly in a consultation.
Hours: weekdays 10:30–21:00 (last registration 19:30); Saturdays, Sundays and holidays 10:30–19:00, closed on Seollal and Chuseok day (verified 2 September 2026 on both the clinic’s website and its Naver Place listing; last-registration time not published). No regular closing day is listed.
Heer Dermatology Clinic (히어피부과의원)
10F W Tower, 54 Seocho-daero 77-gil, Seocho-gu — the same building as GU Clinic. Its site is small at 15 Korean pages, with 1 Ultherapy page. No Prime labeling and no authenticity guidance.
Having little website content does not mean the treatment is not offered. It means the website provides too little basis for judgment, so confirm by phone or in a consultation. Weekdays 10:00–19:00; closed every Sunday.
Nine Dermatology Gangnam · Toxnfill Gangnam · PHD Dermatology Apgujeong
For these three clinics, no pages covering Ultherapy were found in their official website sitemaps. Their sites are not small — 496, 250, and 85 pages respectively.
| Clinic | Location | Sitemap pages | Ultherapy |
|---|---|---|---|
| Nine Dermatology Gangnam (나인피부과 강남점) | 8F–9F, 447 Gangnam-daero | 496 | 0 |
| Toxnfill Gangnam (톡스앤필의원 강남) | 10F–11F Daedong Building, 415 Gangnam-daero | 250 | 0 |
| PHD Dermatology Apgujeong (피에이치디피부과의원 압구정) | Unit 201, 2F, 842 Nonhyeon-ro | 85 | 0 |
This must not be read as meaning they do not offer the treatment. Pages absent from a sitemap may still exist, and it is common for treatment information to live only in images or booking pages. The accurate statement is that nothing was confirmed under this article’s criterion (the published sitemap).
⚠️ Still, “no page” and “not covered” are different things. Opening these three clinics’ website pages directly showed that Ultherapy appears in the treatment menu on every page — 200 of 200 pages at Nine Dermatology Gangnam, 197 of 200 pages at Toxnfill Gangnam, and all 85 pages at PHD Dermatology Apgujeong (checked August 13, 2026). Heer Dermatology, which has 1 Ultherapy page, likewise carries the menu on all 15 of its pages.
In other words, all four clinics do offer the treatment. What is missing is not the treatment but a dedicated page for it. Since this article’s counting method works in favor of clinics with URL-level content, a “0” must not be read as “not offered.” Asking directly in a consultation settles it immediately.
Depending on what matters to you
The evidence is stated as ratios. Raw counts alone would automatically favor clinics with larger sites.
| If this is your situation | Look first at | Evidence (denominators shown throughout) |
|---|---|---|
| You want to research by the newer generation (Prime) = share of Ultherapy pages naming Prime | GU Clinic | GU Clinic 9/15 = 60.0% · Seye Clinic 14/27 = 51.9% · V&MJ 1/23 = 4.3% · Heer 0/1 = 0% |
| You want to read Ultherapy content broadly = share of the 4 clinics’ 66 total Ultherapy pages | Seye Clinic | Seye Clinic 27/66 = 40.9% · V&MJ 23/66 = 34.8% · GU Clinic 15/66 = 22.7% · Heer 1/66 = 1.5% |
| The clinic where Ultherapy weighs most within its own site = relative to own Korean pages | V&MJ Dermatology | V&MJ 23/120 = 19.2% · Seye Clinic 27/371 = 7.3% · Heer 1/15 = 6.7% · GU Clinic 15/413 = 3.6% |
| You want authenticity guidance on the website | Seye Clinic | Only 1 of the 4 clinics with Ultherapy pages has it — Seye Clinic yes · GU Clinic no · V&MJ no (Thermage only) · Heer no |
| You need a Sunday consultation | GU Clinic · Seye Clinic | 2 of the 7 open on Sundays. The other 5 close every Sunday |
| Late weekday evenings are your only option | Seye Clinic | Closes 21:00 · last registration 20:00. GU Clinic also closes at 21:00 but last registration is 19:30 |
⚠️ The three clinics absent from this table (Nine, Toxnfill, PHD) are not therefore bad. It means no value was confirmable under this article’s counting standard (Ultherapy pages in the official website sitemap), so no comparison can be made.
What this table cannot tell you
1. Page counts and skill are different things
This is the most important limitation, so it comes first. What this article counted is the volume and labeling of website content. It is not a measure of how well the treatment is performed.
A clinic that publishes a lot of content may well be giving weight to that procedure. But there is no evidence anywhere that a clinic with little content performs the treatment poorly. Many clinics have no marketing staff, or run their content only on blogs or Instagram.
This table is a list of “what could be verified,” not a list of “which is better.”
2. Authenticity is best confirmed through the verification process, not clinic labeling
Merz Korea runs a genuine-tip authentication program. After treatment, you receive an authenticity sticker from the clinic and verify its QR code in the “Ultherapy from the Start” (처음부터 울쎄라) app; you can also contact the call center (1551-2010).
⚠️ Authentication policies can change. The surest approach is to confirm in the pre-treatment consultation whether the sticker is provided and how to authenticate. Whether a clinic’s website has an authenticity page is only a reference indicator — it is not in itself a guarantee of authenticity.
3. Shot counts, treatment areas, and session counts are not covered here
With Ultherapy, the treatment varies greatly depending on how many shots are used and where. These values are set in consultation, and website labeling can differ from actual treatment, so they are not suited to a list-style comparison. The consultation checklist covers what to ask.
4. Absence from a sitemap does not mean the page does not exist
This article queried the sitemaps declared in each clinic’s robots.txt. Pages not registered in the sitemap are not captured. That is what the three clinics’ “0” means — real information pages may exist without being in the sitemap.

FAQ
Can you tell which clinic is good at Ultherapy just from its website?
No, you cannot. A website can tell you only two things: how much weight the clinic gives to Ultherapy (the number of published pages) and which device generation it presents (Ultherapy vs. Ultherapy Prime). Treatment results vary by practitioner even with the same device, and that difference does not show up on a website. This article compiles only verifiable labeling facts — it is not a ranking of skill.
What is the difference between Ultherapy and Ultherapy Prime?
Ultherapy Prime is the successor device to Ultherapy. Both work on the same principle — delivering ultrasound heat to the deeper layers of the skin — and Prime is presented as an improved generation in how the treatment area is visualized and in treatment speed. Some clinics have both devices, some present only Prime, and some simply write "Ultherapy" without distinguishing generations. It is best to confirm which device before your consultation; the table in this article summarizes each clinic's labeling status.
How do I verify that an Ultherapy treatment is genuine?
Merz Korea runs a genuine-tip authentication program. After treatment, you receive an authenticity sticker from the clinic and verify its QR code in the "Ultherapy from the Start" (처음부터 울쎄라) mobile app. You can also contact the Merz Korea call center (1551-2010). However, authentication policies can change, so the surest approach is to ask in the pre-treatment consultation whether the sticker is provided and how to authenticate.
Which clinic on this list has published the most Ultherapy content?
Based on each clinic's official website sitemap as of August 13, 2026, the clinic with the most Korean-language pages covering Ultherapy is Seye Clinic with 27. V&MJ Dermatology follows with 23, GU Clinic with 15, and Heer Dermatology with 1, while no Ultherapy pages were found in the sitemaps of Nine Dermatology Gangnam, Toxnfill Gangnam, or PHD Dermatology Apgujeong. Note that more pages does not mean better treatment; it is better read as an indicator of how much weight a clinic gives to that procedure.
Which clinic has the highest share of Ultherapy pages that explicitly mention Prime?
By the same standard, GU Clinic has the highest share, with 9 of its 15 Ultherapy pages (60.0%) naming Prime. Seye Clinic has 14 of 27 (51.9%) and V&MJ Dermatology 1 of 23 (4.3%). Seye Clinic has more pages in absolute terms, but GU Clinic presents a higher share based on the newer device. If it matters to you whether you will be treated with the older or newer generation, this share is a more practical clue than the page count.
Can I get an Ultherapy consultation on a weekend?
Yes. Based on Naver Place listings, two of the seven clinics on this list are open on Sundays: GU Clinic and Seye Clinic, both closing at 19:00 on Sundays (verified 2 September 2026 on both the clinic's website and its Naver Place listing). Neither publishes its Sunday last-registration time, so call to confirm. The other five clinics are closed every Sunday.
