I have a somewhat peculiar habit: before deciding on a treatment plan, I copy all the reviews online into Excel. This time, to figure out “where exactly in Seoul one should get an HIFU treatment,” I transcribed one by one every review and feedback about HIFU treatments at Umi Dermatology in Myeongdong from Naver, Dcard, and REDnote. By the time I reached review number 30, I stopped—for the same clinic and the same treatment, some people said their chin lines really softened, while others claimed they didn’t notice much difference despite spending money on it.
At first, I thought someone was doing paid promotion or causing trouble. But after reclassifying the reviews based on “number of posts, number of treatment sessions, who performed the procedures, and when they were written,” I realized the extreme opinions actually made no sense at all—they weren’t talking about the same thing at all.
I’m not planning to create another list of things to pick up while shopping (I already wrote that in the article about the price list at Myeongdong CDU Dermatology). This time, I’ll do just one thing: analyze the feedback on the HIFU treatment at Myeongdong CDU Dermatology as reference material, so you can tell which reviews are worth paying attention to and which ones aren’t really relevant to you.
Why are the reviews for HIFU treatments at Umi Dermatology in Myeongdong so mixed? It comes down to the number of sessions, treatment depth, and who performs the procedure.
HIFU, such as the popular Shurink series and authentic Ulthera devices in South Korea, doesn’t deliver an instant “glowing” effect like dermal fillers—where results are visible already the day after treatment. Instead, it uses focused ultrasound to create heat-coagulation points beneath the skin, causing the fascia layer to contract and stimulate collagen regeneration. As a result, the visible outcomes typically take 1 to 3 months to appear.
So, a one-star review saying “I didn’t notice any change on the day of the procedure” and a five-star review stating “A colleague asked me a month later if my face looked slimmer” were likely written by the same machine and the same doctor. The only difference lies in when the reviews were posted.
If you can only remember one part of this article, just keep this table in mind. Whenever you come across a review of HIFU, first check whether these three points are mentioned; reviews that don’t cover all three actually have very limited reference value.
| Variables | Why are there mixed reviews? | Questions to Ask When Reading Comments |
|---|---|---|
| ① Number of posts | Both referred to as HIFU, the 300-shot and 600-shot versions offer two different experiences. The lower shot count comes at a lower price with nice results, but the sensation is also less intense. | “How many shots will he use? Is it the same number as what you quoted me?” |
| ② Layers (probes) | 1.5mm/3.0mm/4.5mm needles target the dermis, fat, and SMAS fascia—by adjusting the combination ratio, you can achieve either a firmer appearance or sharper contours. | “Did he get a full face treatment or just have his jawline enhanced?” |
| ③ Injector | The difference in injection density between a doctor’s direct injection and an assistant’s injection using the same device is one of the most frequently discussed topics on Korean online forums. | “Did the message say it was written personally by the director?” |
These three factors also explain one thing: why comparing prices across different clinics often doesn’t yield meaningful results. The pricing logic behind services like Seongsu Newland’s ₩990,000 ultra-sound therapy device is fundamentally different from the package pricing offered by shopping district-based clinics in Myeongdong—they’re based on two entirely separate calculation methods.
Regarding the reputation of the HIFU treatment at Umi Dermatology in Myeongdong, there are actually only four different opinions.
After sorting through the comments, I found that there were only a few recurring themes. I used a four-quadrant system to organize them and also marked whether “this comment is useful to you” or not.
| Sound Type | Common phrases used by netizens | Credibility/Value as a reference for you |
|---|---|---|
| A. Maintain strong reviews | “The director performs the procedure himself throughout, checking along the way to see if it’s too painful.” | ★★★★★ Describes the entire process, making it extremely difficult to fake. |
| B. Highly rated for excellent communication | “I can speak Chinese, so there’s no need for gestures. I’ll clarify in advance how many implants will be placed during the consultation.” | ★★★★☆ Crucial for foreigners – worth checking out |
| C. Disappointment upon arrival | “You can’t tell much right after the procedure; it’s a bit disappointing.” | ★★☆☆☆ Most likely the feedback period hasn’t arrived yet — just check the posting date to see. |
| D. Environmental noise | “Myeongdong is too noisy.” “You need to look for the elevator.” | ★☆☆☆☆ Has nothing to do with the treatment itself; just check it out. |
It’s worth noting that categories A and B account for the majority, and their responses are highly consistent—this usually indicates that the clinic operates in a stable manner. On the other hand, if all the positive reviews about a clinic focus solely on low prices without anyone mentioning details about the procedures, that’s something worth considering more closely.
How much weight does “direct treatment by the director” really carry in customer reviews?
Myeongdong Umi features a dual-CEO system, which is actually quite uncommon in smaller clinics—and this directly influences the nature of the feedback received.
| Doctor | Mainly responsible for | The points most frequently mentioned in reviews |
|---|---|---|
| Dr. Yin Zhongyu, Director | Injectable and anti-aging firming treatments | The technician maintains a steady pace and adjusts the focus areas according to the face shape, without pushing hard-selling packages. |
| Dr. Kim Nan-young, Director | Equipment-based treatments, Chinese-speaking service | You can explain the layers and quantities in Chinese, reducing communication stress with foreign guests. |
I personally think the phrase “performed by the director in person” has been overused to death, but when it comes to HIFU treatments, it does make sense: the machine remains the same, and what determines the outcome is the density and placement of the probe’s movements. This follows the same logic as what Apgujeong DM Dermatology offers—where the treatment leaves no visible signs that anything was done—so the difference isn’t in the list of equipment, but in who holds the probe.
Another reality: In the Myeongdong area, a large proportion of customers are foreigners, so the ability to communicate clearly is itself part of building a good reputation. You certainly don’t want to rely on translation apps in your consultation room to decide how many treatments to recommend.
Prices at Umi Dermatology in Myeongdong: There’s no public quote available for the HIFU treatment, but this table reveals its unique pricing structure.
Let’s get to the bottom of it first: There is no fixed price for the HIFU treatment at CDU in Myeongdong, as the cost varies depending on the number of sessions, the treatment area, and whether other procedures are included. This is actually common practice at most clinics in South Korea, so don’t think anything is suspicious just because there’s no listed price.
However, from the publicly listed pricing for its collagen hydration treatments, one can tell this clinic’s unique pricing strategy—it doesn’t rely on ultra-low prices to attract customers, nor does it charge premium prices like the flagship store in Gangnam.
| Projects with publicly available quotes | Reference Price (KRW) |
|---|---|
| Juvelook Black Bottle, 1 bottle | ₩650,000 |
| Juvelook Natural Look Blue Bottle – 1 Small Bottle | ₩650,000 |
| Ellevie RE20 Collagen Glow Injection – 1 Session | ₩720,000 |
| Saidiyen Real Skin Collagen Glow Injection – 1 Bottle | ₩650,000 |
| Revice 1CC | ₩450,000 |
| HIFU | Quotations are provided based on the number of sessions/areas treated. It’s recommended to check available slots and get a quote online first. |

Just done / 7 days / 1 month: Check out the customer reviews again on the timeline
As mentioned earlier, the biggest factor that affects HIFU reviews is “when they were written.” I sorted the comments by posting time, like this:
| Timing | The most common descriptions from netizens | How to interpret it |
|---|---|---|
| Right after it was done | “It feels a bit prickly and warm, my face is slightly red, but I can go shopping right away.” | This stage focuses on the physical sensations and recovery period, not the results. |
| About 7 days later | “It feels a bit tighter to the touch, but it’s hard to tell from photos.” | The collagen is still in the process of rebuilding, so it’s actually too early to give a negative review at this stage. |
| 1 month later | “My jawline is more defined now; my colleagues asked if I’ve lost weight.” | Most positive reviews focus on this section, which is part of the typical feedback period. |
| 3 months later | “It feels a bit less, but it’s better than before I had it done.” | Normal metabolism – determining when it’s time to consider a follow-up treatment |
So if you see a two-star review that says “I didn’t feel anything three days after the procedure,” the real takeaway from that review is—he went ahead and wrote it three days later.
Who will be satisfied and who will be disappointed? Check this table first before making a decision.
| ✅ High chances of satisfaction | ❌ It’s recommended to think it over again. |
|---|---|
| Since the itinerary is already in the Myeongdong/Dongdaemun area, I don’t want to make an extra trip to Gangnam for the treatment. | Hoping for that instant transformation — looking like a completely different person right after the procedure |
| Looking to improve sagging lower jaw lines and blurred contours; willing to wait for a 1-month results period | Recent facial wounds, sunburn, inflamed acne, or undergoing acid-based treatments |
| I care about the quality of communication and hope someone can explain the number of applications and layers in Chinese. | Having metal implants in the face, a pacemaker, or being pregnant or breastfeeding |
| Don’t want to be tied to a package; prefer to adjust the number of treatments based on needs | Having a wedding or important photoshoot in two weeks – worried that mild swelling might affect it |
💡 Quick tip: The above are general guidelines only. Whether they’re suitable for you actually depends on your skin condition and medical history. It’s better to consult via LINE before heading out to feel more at ease. If you’re still deciding on a location, you might also want to check out reviews of the 7 Dermatology clinics in Dongdaemun.
Beyond checking reviews, it’s best to avoid these 5 pitfalls first.
- ☑ Don’t just compare the total price: First, clarify the number of units and the number of treatment layers. Otherwise, what seems cheap might actually be just half a set.
- ☑ Don’t skip the consultation and place an order right away: If the areas to be enhanced aren’t clearly specified, it’s easy to end up disappointed with the result, feeling like nothing changed.
- ☑ Stop drawing conclusions right after the procedure that week: The feedback period hasn’t arrived yet, and you might scare yourself.
- ☑ Avoid scheduling too many treatments on the same day: If you want to combine fillers or injections, first ask your doctor about the proper interval between them.
- ☑ Don’t wait until the last minute to book: Slots are in high demand in Myeongdong on weekends, so it’s recommended to secure your appointment 3–7 days in advance.

Top Questions People Ask About Reviews of the Umi HIFU at Myeongdong
Q1: Can foreigners book directly? Is a South Korea phone number required? Y
es. You can book through BeautsGO or LINE without needing a South Korean number—just specify the services you want, the desired date, and the number of people.
Q2: Why isn’t the price of HIFU listed directly? That’s because the cost
depends on the number of sessions, the treatment area, and whether it’s combined with other treatments. The best approach is to ask the provider to write down “model + number of sessions + treatment area” during consultations, so you can compare prices based on these details.
Q3: Will it hurt? Most people describe i
t as “intermittent heat and tingling,” with the sensation being more intense in areas where the bone structure is more pronounced. You can respond during the procedure, so feel free to ask your doctor to adjust the intensity or administer the treatment in stages.
Q4: Can you wear makeup and go shopping on the day of the procedure? It us
ually doesn’t interfere with your plans, though your face might be slightly red. It’s recommended to avoid hot saunas, steam baths, and alcohol on that day.
Q5: Can it be done together with hyaluronic acid injections? Many people
schedule these treatments in the same visit, but the order and interval need to be determined by a doctor. If you want to learn more about the hyaluronic acid treatment options offered at this clinic, you can check out the price list for CDU’s collagen hyaluronic acid injections in Myeongdong.
Q6: How often is it appropriate to have it done? Typically,
it’s recommended to evaluate every 6 to 12 months, though the actual interval still depends on the skin condition and the parameters used in the previous treatment.
My conclusion: Word of mouth matters, but you should look at those reviews that provide detailed explanations.
Returning to the initial question—why are the reviews of HIFU treatments at the same clinic so polarized? After analyzing it, my answer is: most of this disparity isn’t due to the clinic itself, but rather because the reviews don’t specify the conditions under which the treatments were performed.
When it comes to Umi Dermatology in Myeongdong, its reputation is pretty well-defined: it’s conveniently located, open until 9 p.m. on weekdays, staffed by doctors who handle treatments personally, and offers services in Chinese—making it ideal for those whose itinerary includes a visit to Myeongdong and who want to take advantage of anti-aging treatments as well. It’s not one of those flagship clinics that promise dramatic results overnight; if you’re expecting huge transformations, you might be disappointed. But if what you’re looking for is clear communication and transparent explanations about the treatment procedures, it’s a quite practical choice in the Myeongdong area.
Next time you come across mixed reviews, ask yourself those three questions first: how many sessions, which treatment level, and who performed it. Once you’ve asked them, you’ll naturally know whether that review counts or not.
