Gangnam Skin Clinics: 13 Compared by Opening Days, Sundays and Holidays (2026)
In one line: Thirteen Gangnam skin clinics are bookable in English, and the thing that most often decides which one you can use is not the treatment list — it is whether they open on the day you are free.

If you are visiting Seoul and want to see a skin clinic in Gangnam, the English-language guides will tell you about treatments. Almost none of them tell you which clinics are open on a Sunday — which, for someone on a short trip with a fixed itinerary, is usually the question that decides everything else.
This guide compares thirteen Gangnam skin clinics on opening days and hours only. Checked 12 August 2026.
How do I book a skin clinic in Gangnam as a tourist?
Short answer: online, in English, before you fly. Walking into a Gangnam clinic without a reservation is possible but wastes the trip if the day is wrong, and most clinics take bookings through a platform rather than by phone. Four channels take English bookings for Korean clinics:
| Channel | What it is best for | Trade-off |
|---|---|---|
| K-Beauty Station | Business-level listings with seven-day opening hours and won prices; 46 of its 141 listings are medical | No free-cancellation guarantee |
| Klook | Packaged clinic treatments and consultations, free cancellation on most listings | Dollar pricing, no opening hours |
| Creatrip | Editorial guides and its own bookings | No per-clinic rate published |
| Naver Booking | The widest coverage in Korea by far | Korean-language interface |
You do not need a Korean phone number for any of them — see booking without a Korean number.
The part the channels cannot decide for you is the day, and that is what the rest of this guide is for: six of the thirteen Gangnam skin clinics open on Sunday, five open on public holidays, and one closes on a Thursday.
The short answer on Gangnam hours
- Open on Sunday — six of thirteen: SECRET CLINIC, GU Clinic Gangnam, CELLIN CLINIC GANGNAM, UH CELL CLINIC GANGNAM, Dr. Evers Gangnam, DIORE CLINIC. All but one close earlier on Sunday than on a weekday — CELLIN CLINIC GANGNAM’s Sunday close of 15:30 matches its Monday, which is already its short day.
- Open on public holidays — five of thirteen: SECRET CLINIC, GU Clinic Gangnam, CELLIN CLINIC GANGNAM, DIORE CLINIC, GD Clinic.
- Open latest on a weekday — GU Clinic Gangnam Branch, to 21:00. It is also one of four clinics open on both Sunday and public holidays, and the only one of those four that runs to 19:00 on both.
- ⚠️ Closed on a weekday — KK Seoul Clinic is closed every Thursday. It is the only one.
- The odd one out — GD Clinic closes on Sunday but stays open on public holidays, to its full 20:00. Every other clinic that opens on a holiday also opens on Sunday.
Why opening days and not treatments
Two reasons, and the second is the one that matters more.
First, availability is the binding constraint on a short trip. A treatment list is only useful once you know the door will be open. Most visitors have two or three usable windows in a week-long trip, and a surprising number of those windows fall on a Sunday or a holiday.
Second, treatment and price comparison is not something a guide should do for medical care. What is appropriate for your skin is determined in a consultation, by a doctor, looking at your skin. A guide that ranks clinics by treatment or price invites you to skip that step. Opening hours are publicly listed operating facts and carry no such problem, so that is what this guide compares.
This guide publishes no treatment prices. If you want to know what something costs at a particular clinic, ask that clinic when you consult, so the number is attached to an actual recommendation.
All thirteen, by day
Ordered by review count, largest first. This is not a ranking — review volume mostly reflects how long a clinic has been listed, and the order carries no judgement of clinical quality.
| Clinic | Weekday close | Saturday | Sunday | Public holiday | Rating (reviews) |
|---|---|---|---|---|---|
| GU Clinic Gangnam Branch | 21:00 | to 19:00 | Open to 19:00 | Open to 19:00 | 4.9 (10,388) |

| Le Well Clinic | 20:00 | to 16:00 | Closed | Closed | 4.7 (12) |
| SECRET CLINIC | 20:30 | to 17:30 | Open to 17:30 | Open to 17:30 | 5.0 (2) |
⚠️ KK Seoul Clinic is closed on Thursday — see below.
On the review counts: these are the exact figures held in the platform’s listing data. The website displays them rounded into bands — GU Clinic shows on the page as “4.9 (10,000+)”. They are user reviews on a booking platform, not a clinical outcome measure and not medical advertising.

Three patterns are visible here that the summary table above flattens.
Nobody opens before 10:00. Eight of the thirteen open at 10:00, four at 10:30, and Reverse clinic Gangnam at 11:00. If you want a genuinely early appointment before a day of sightseeing, this category cannot give you one — the earliest door in Gangnam opens at 10:00.
Saturday is a short day almost everywhere. Not one clinic keeps its weekday closing time on Saturday. The latest are CELLIN and GU Clinic at 19:00; the earliest are KK Seoul and Le Well at 16:00.
The holiday column is the most varied. Five open, eight close, and the five that open do not all keep the same hours — CELLIN runs to 20:30 on a holiday — the same as Tuesday through Friday, not longer — while SECRET and DIORE run to 17:30 and 17:00.
Sunday splits the list almost in half
Six open, seven close. That is the single most useful fact on this page, and it is not visible anywhere in the treatment-focused guides.
Sunday, Gangnam skin clinics
Open ██████ 6 SECRET · GU · CELLIN · UH CELL · Dr. Evers · DIORE
Shut ███████ 7 Reverse · Abijou · KK Seoul · GD · AB · WJ Wonjin · Le WellTwo things follow from it.
Every Sunday-opening clinic closes early. The latest is GU Clinic at 19:00; the earliest is CELLIN at 15:30. None keeps its weekday closing time. A Sunday appointment is a morning or early-afternoon appointment, not an evening one.
The rating range is the same on both sides of the split. Clinics that open on Sunday run 4.8 to 5.0; clinics that close run 4.6 to 4.9. Sunday opening tells you about scheduling, not about quality — so if Sunday is your only window, you are not choosing from a worse list.
Public holidays are a different list again
Five of thirteen open, and the membership is not the same as the Sunday list.
| Sunday | Public holiday | |
|---|---|---|
| SECRET CLINIC | Open | Open |
| GU Clinic Gangnam | Open | Open |
| CELLIN CLINIC GANGNAM | Open | Open |
| DIORE CLINIC | Open | Open |
| GD Clinic | Closed | Open |
| UH CELL CLINIC GANGNAM | Open | Closed |
| Dr. Evers Gangnam | Open | Closed |
GD Clinic is the exception worth remembering. It closes on Sunday but keeps full weekday hours on public holidays, to 20:00. That is the second-latest holiday closing here; CELLIN CLINIC GANGNAM runs later still, to 20:30. If your trip lands on Seollal or Chuseok, that is a different shortlist from the Sunday one.
Korean public holidays include multi-day periods when much of the city shuts. Check your specific dates rather than assuming the listing covers them.
The three that shorten or close a weekday
Most clinics keep the same hours Monday to Friday. Three do not, and one of those is a full closure.
KK Seoul Clinic Thu CLOSED all day ← the only weekday closure
CELLIN CLINIC GANGNAM Mon 10:00–15:30 (Tue–Fri run to 20:30)
UH CELL CLINIC GANGNAM Thu 10:00–17:00 (Mon, Tue, Wed, Fri run to 20:00)None of these is visible from a clinic’s headline hours, which is exactly why they strand people. If you are booking a specific weekday, check that weekday rather than the general listing.
Saturday, and the morning question
Two practical facts that get lost in the Sunday discussion.
Every clinic opens on Saturday, and every clinic shortens it.
Saturday closing times, 13 Gangnam skin clinics
19:00 ██ 2 CELLIN · GU Clinic
18:00 █ 1 GD Clinic
17:30 █ 1 SECRET CLINIC
17:00 ██████ 6 UH CELL · AB · Dr. Evers · DIORE · WJ Wonjin · Reverse
16:30 █ 1 Abijou Gangnam
16:00 ██ 2 KK Seoul · Le WellSix of thirteen close at 17:00, which makes Saturday afternoon a much tighter window than a weekday evening. If Saturday is your day, treat 15:00 as the practical latest arrival rather than the stated closing time.
Mornings are not an option before 10:00. Every clinic opens between 10:00 and 11:00. A common visitor plan — clinic first thing, then the rest of the day free — does not work in this category. Build the appointment into the middle of the day instead.
Three questions that narrow thirteen to one
1. Which day are you actually free? Sunday removes seven of thirteen. A public holiday removes eight. A Thursday removes KK Seoul Clinic. Start here, because it does more filtering than anything else.
2. How late do you need it to be? If you can only go after work hours, GU Clinic at 21:00 is the latest, followed by three at 20:30. On a Sunday the latest is 19:00.
3. Does a large review base matter to you? If yes, that narrows to GU Clinic, Abijou Gangnam and UH CELL, all above 1,600. If not, the smaller listings sit in the same rating band and may simply be newer to the platform.
Whatever you pick, the treatment decision happens in the consultation, not before it. And once the booking is in, the clinic has to be able to reach you to confirm it — how Seoul beauty bookings actually contact you covers what arrives, on which channel, and the signup fields that decide whether you are reachable.
Where the seven-day data comes from
Thirteen Gangnam clinics can be lined up day by day only because one platform, K-Beauty Station, publishes a seven-day schedule for each of them. The other channels we checked on 12 August 2026 either sell activity slots without business hours or publish editorial picks with no hours at all, so a grid like this could not have been built from them. How that data works, and where it stops, is set out in the weekday closures guide.
What you can check before a treatment, even in a language you do not read
Opening hours get you through the door. This section is about the twenty minutes after that, and it is the part where a visiting patient is at the biggest disadvantage — not because clinics behave differently with foreigners, but because the things worth checking are checked by asking, and asking is exactly what a language barrier removes.
The useful frame here is not “is this clinic good”, which you cannot determine in a consultation. It is: you cannot see the result in advance, but you can see the conditions. Those are concrete, and most of them appear as numbers on a machine.
1. Who performs it? In Korea, energy-device treatments are medical procedures that only a licensed medical practitioner may perform. The person who consults with you is not always the person who treats you. Ask which it is.
2. What is the device, and which generation? “HIFU lifting” and “RF treatment” are categories, not products. Ask for the device name, and for RF devices the generation as well — these are different machines with different settings, and the name is a fact rather than an opinion.
3. Is the cartridge or tip opened in front of you? For both HIFU and RF, the single-use consumable is a large share of what the treatment costs. That makes it the part where substitution is possible and hardest for a patient to see. A sealed consumable opened in your presence removes the question entirely. This is a request, not an accusation — it is normal to ask.
4. Can you see the shot count? When a genuine consumable is loaded, the machine displays the shots available and counts down as it fires. Noting it at the start and again at the end tells you what was actually delivered. This travels across a language barrier better than anything else on this list, because it is a number on a screen you can photograph.
5. Were the downsides explained before you asked? A consultation that covers recovery time and possible side effects without being prompted is behaving the way a medical consultation should. One that only describes benefits has skipped a step.
Why this matters more for a visitor
A local patient who is unhappy can return, follow up, and escalate. On a short trip you have none of those. Whatever is going to be verified has to be verified before the treatment starts, because afterwards you are on a plane.
Two practical adjustments:
- Ask in writing. Send the questions in the booking message rather than saving them for the chair. You get a considered answer, in text, that survives translation — and you learn how the clinic handles being asked.
- Photograph the screen. Shot counts and device names are legible in a photo regardless of language. This is ordinary patient record-keeping.
Where this comes from
Our Korean-language guides work through each of these in more depth than an opening-hours guide can. They are written for a domestic readership, so they assume Korean, but the checks themselves are language-independent and the device names are the same worldwide:
- Seven things to check before a clinic consultation (in Korean) — the seven-point checklist this section condenses
- How to verify a genuine Thermage tip (in Korean) — RF tips, device generations and how shot counting works
- What to look at when choosing for Ultherapy (in Korean) — HIFU cartridges, depth selection and who operates the device
None of this is a comment on any clinic listed on this page. These are category-wide consumer checks that apply to any provider anywhere, and we list clinics here on opening hours alone.
Gangnam is the deep end; Myeongdong is the convenient one
Gangnam holds sixty-five listings on this platform against Myeongdong’s fourteen, and thirteen skin clinics against Myeongdong’s six. If you want choice within the category, this is where it is.
What Myeongdong has instead is proximity to everything else you are doing. Its clinics close at similar times — every Myeongdong skin clinic shuts by 21:00, the same ceiling as here — but you are not spending an hour each way. The evening hours for every Myeongdong listing sets that list out the same way.
One Gangnam clinic on this page also appears in our weekday-closure list. KK Seoul Clinic is shut every Thursday, and it is one of eleven Seoul listings with a weekday closure — the full eleven are here.
What the schedule does not tell you
- The scope of this guide. We checked one booking platform, K-Beauty Station, on 12 August 2026, and included the thirteen Gangnam listings it categorises as skin clinics. Gangnam has many more skin clinics that are not listed there or do not publish in English. This is not every skin clinic in Gangnam; it is every one on that platform.
- Whether the holiday field is complete. All thirteen clinics record a holiday value, but Korean public holidays vary in length and the listing does not name which dates it covers.
- The last bookable appointment. A 21:00 close does not mean a 20:30 appointment. None of the listings publishes a final slot time.
- Which language the consultation runs in. The listings are published and bookable in English. None states who will be in the room, and a dermatology consultation is a conversation.
- Whether hours hold during Seollal and Chuseok. These are multi-day closures for much of the city and are not separately listed.
- Anything about treatments, outcomes or suitability. This guide compares opening hours. It does not compare clinics on care, and nothing here should be read as a recommendation of one clinic over another.

FAQ
Are skin clinics in Gangnam open on Sundays?
Some are and most are not, and it is close to an even split. Of the thirteen Gangnam skin clinics listed in English on K-Beauty Station, six open on Sunday — SECRET CLINIC, GU Clinic Gangnam, CELLIN CLINIC GANGNAM, UH CELL CLINIC GANGNAM, Dr. Evers Gangnam and DIORE CLINIC. Seven close entirely: Reverse clinic Gangnam, Abijou Clinic Gangnam, KK Seoul Clinic, GD Clinic, AB Clinic, WJ Wonjin and Le Well Clinic. Every clinic that opens on Sunday closes earlier than on a full weekday, mostly between 15:30 and 19:00, so a Sunday appointment has to be an early one. The one qualification is CELLIN CLINIC GANGNAM, whose Sunday close of 15:30 is the same as its Monday rather than earlier.
What happens on Korean public holidays?
Five of the thirteen stay open and eight close. The five are SECRET CLINIC, GU Clinic Gangnam, CELLIN CLINIC GANGNAM, DIORE CLINIC and GD Clinic. GD Clinic is the interesting one — it closes on Sunday but keeps full weekday hours, 10:00 to 20:00, on public holidays, which is the opposite pattern to everyone else. Korean public holidays include several multi-day periods such as Seollal and Chuseok when much of the city shuts, so this is worth checking against your specific dates rather than assuming.
Which Gangnam skin clinic is open latest?
GU Clinic Gangnam Branch, to 21:00 on weekdays. It is also open on Sunday to 19:00 and on public holidays to 19:00, which makes it the most consistently available clinic on the list by a clear margin. It holds 10,388 reviews at 4.9, the largest review base of any clinic here. Several others run to 20:30 — SECRET CLINIC, Dr. Evers Gangnam and DIORE CLINIC — and CELLIN CLINIC GANGNAM also reaches 20:30 from Tuesday onward.
Do any Gangnam skin clinics close on a weekday?
One does. KK Seoul Clinic is closed all day Thursday while opening Monday, Tuesday, Wednesday and Friday. It is the only clinic of the thirteen with a weekday closure, and it is the kind of detail that is easy to miss because nothing else in the category behaves that way. Two others shorten a weekday rather than closing it: CELLIN CLINIC GANGNAM finishes at 15:30 on Monday instead of 20:30, and UH CELL CLINIC GANGNAM finishes at 17:00 on Thursday instead of 20:00.
Does a bigger review count mean a better clinic?
It mostly reflects how long a clinic has been listed and how much volume it does, not outcome quality. The spread on this list is enormous — GU Clinic Gangnam holds 10,388 reviews while SECRET CLINIC holds 2 — and the ratings sit in a narrow band from 4.6 to 5.0 regardless. A clinic with a small review count may simply be newer to the platform. These are user reviews on a booking platform; they are not a clinical outcome measure, and what treatment is appropriate for you is decided in a consultation.
Why does this guide not list treatment prices?
Korean law regulates how medical treatment is advertised, and publishing clinic-by-clinic treatment prices in a comparison guide is not something we do. Opening hours are factual, publicly listed operating information and carry no such issue, which is why this guide is built on them. If you need to know what something costs at a specific clinic, ask that clinic directly during the consultation, when the answer can be attached to what you are actually being recommended.
