Shetang is not Gangnam! In-depth review of Shetang Essenee Essential Dermatology’s Korean-style HIFU: After just one month, my face shape became more refined, and friends asked if I had gotten facial bone reduction.

Sis, let me tell you—this time when I went to Seoul for an HIFU treatment, I didn’t head to Gangnam or Myeongdong. Instead, I went to Saetang. My friends were totally shocked when they heard that: “Saetang? Isn’t that just a residential area? What kind of Dermatology clinic is there?”

A month after the procedure, the same friend stared at my face and asked, “Did you secretly get bone reduction? Why is your chin so pointy?”

No need to shave away bones at all! It’s the Essential Dermatology version of the HIFU device—just one treatment, one hour, no recovery time required, yet the results are like having a completely new face. Plus, it’s 20% cheaper than those in Gangnam. I really regret not discovering such a gem of a clinic earlier.

In this article, I’ll break down the entire experience from start to finish for you: how to get there, how much it costs, what kind of doctor is in charge, how long it takes to see results, and how it compares to the American version—all shared in complete honesty without any filters.

Where exactly is Essential Dermatology at She Tang Aisinxiu? The transportation is even more convenient than you think.

Many people think “Sadang” is a far-off place as soon as they hear the name, but in reality it’s right at Exit 14 of Sadang Station—the intersection of Seoul Subway Lines 2 and 4. It only takes a 1-minute walk from there to reach the 8th floor of the JBI Building. That’s right, really just 1 minute—no need even to use navigation.

If you start from Myeongdong, you can take Line 4 straight to there without any transfers—it only takes about 20 minutes. Coming from Gangnam Station, Line 2 gets you there in just 10 minutes as well. Compared to having to hunt around for clinics hidden in narrow alleys in Gangnam, this place is truly a lifesaver for those who get lost easily.

5 Key Advantages of Essential from Aisen Show: PTT and Dcard – Features Most Frequently Mentioned by Taiwanese Girls

1. “The director performs the procedure personally throughout the whole process, rather than handing it over to nurses” — this point has been mentioned countless times on Dcard. Director Ryu Joo-hee takes care of everything from the initial consultation to the actual treatment. Unlike some clinics where someone else takes over after just 5 minutes of the consultation, this approach provides much greater peace of mind for those undergoing HIFU treatment for the first time.
2. “There’s no pressure to sell services; in fact, they’ll even advise you against getting procedures you don’t need,” shared a netizen on PTT. She originally wanted to get Botox, but after an evaluation, the clinic director said, “Your masseter muscles aren’t very developed, so there’s no need for injections.” Such a client-focused attitude is truly rare in South Korea’s cosmetic industry.
3. “All three female clinic directors pursue a natural aesthetic approach—results don’t look like wax figures after treatment.” Liu Zhuxi, Li Xiaona, and Li Xiaozhen are all women who deeply understand women’s desire for “natural beauty.” Users on Dcard consistently report that after HIFU treatment, “it’s hard to tell where anything was done, but they definitely look better.”
4. “Full Chinese translation support throughout the process — even the post-surgery care instructions will be provided in Chinese.” For those who don’t speak Korean, this directly solves the biggest challenge. The translation service covers everything from skin assessment to post-operative follow-up, ensuring seamless communication.
5. “Transparent pricing – 20% cheaper than Gangnam, with an outstanding cost-performance ratio.” The lower rent in the She Tang area means significantly better prices for these treatments. For high-cost procedures like HIFU and Thermage, the savings can even cover an additional session of hyaluronic acid injection.

Dr. Ryu Joo-hee’s philosophy in practice: Why “precision” matters more than “doing everything”?

Dr. Yu Ju-hee boasts 12 years of clinical experience in the field of Dermatology in South Korea. Her approach to patient care can be summarized in three words: meticulous, thorough, and precise.

First, she’ll use a high-end skin analysis device to scan the entire face, assessing the condition of the epidermis, dermis, and fascia layers before discussing options with you. It’s nothing like those perfunctory consultations where they just say, “Your skin is a bit dry—let’s do a hyaluronic acid treatment.”

It’s slow — the in-person consultation takes at least 20 minutes. She’ll ask about your skincare habits, whether you’ve had any other cosmetic treatments, and what results you’re hoping for. She might even ask which side of your face you usually use for photos, as this affects the strategy for distributing energy during the treatment.

Ready — her approach to using HIFU emphasizes “zone-specific customization”: high energy is applied to the jawline, medium energy to the Buccal Fat, and low energy around the eyes. Each treatment beam is precisely targeted at the SMAS fascia layer, ensuring no generic full-face treatment is performed just to save time.

This “age-specific customization” approach essentially means that the treatment strategies for sagging skin at 25 and drooping skin at 40 are completely different. Director Liu never uses the same parameters for everyone—this is where a doctor’s true expertise is truly tested.

Besides HIFU, what other treatments are available at Aisenxiu?

If you’re visiting for the first time just like me, Director Liu’s advice is: don’t treat your face like a laboratory—pick 1–2 key treatments at a time. Here are some options that work particularly well when combined with HIFU:

Rejuran PN Injection – The Ultimate Partner of HIFU

HIFU targets sagging skin, while Rejuran addresses dryness and dullness. The logic behind using them together is that as the fascia tightens, the texture of the skin itself needs to improve as well. Rejuran provides deep-level hydration and repair, giving the skin a radiant, “well-hydrated” appearance. Some users on Dcard have described it as having “a filter effect” after treatment.

InMode Face FX — The “precision tool” tailored for refining the jawline

If your Double Chin is caused by fat rather than sagging skin, combining HIFU with InMode offers a truly remarkable solution. InMode uses radiofrequency energy to break down fat in the lower jaw, while HIFU tightens the fascia. By working together, it gives your chin line a real chance to go from appearing blurred to looking sharp and defined.

You can’t tell where anything was done after the procedure, but it just looks better—Aisen Show’s “unintentional” beauty aesthetic

This is what makes Aisen Show stand out—the very reason why locals in South Korea particularly love this place.

Many clinics aim for “visible changes right after the treatment,” but Aisenxiu pursues the exact opposite — “A month after the procedure, friends think you look better, though they can’t quite pinpoint what’s changed.”

The underlying principle behind this effect isn’t complicated at all: it doesn’t alter your bone structure but rather helps bring out the contours you already have. It’s like ironing out a wrinkled piece of clothing—the clothing remains the same, but its texture is completely different.

The aesthetic approach of these three female directors all follows the same principle: no chasing trends, no sticking to templates, and no creating “plastic surgery faces.” They design a customized energy distribution plan based on your natural facial structure, so that after the treatment, you end up looking like a refined version of yourself—not a copy of some preset template.

Essential Dermatology in Seto vs. Other Top-Ranked Dermatology Clinics in Gangnam District

To sum it up: if what matters to you is “looking better without anyone noticing after the treatment,” choose Aisen Show; if you’re looking for “immediate, noticeable changes right after the procedure,” then the clinics in Gangnam might be more suitable for you. There’s no such thing as right or wrong—only what fits you best.

Comprehensive Review of PTT/Dcard CDU: Honest Feedback from Taiwanese Girls

What’s like the environment at Essential Dermatology?

Stepping into the 8th floor of the JBI building, the first impression is that it doesn’t resemble a clinic at all but rather a high-end SPA. Warm-toned lighting, a subtle scent of essential oils, and gentle background music—there’s absolutely no cold, oppressive atmosphere typical of hospitals.

The sofas in the waiting area are extremely comfortable, accompanied by tea and the latest South Korea magazines. What’s worth mentioning is that there’s plenty of space between each seat, so you won’t feel awkward sitting next to strangers. This thoughtful detail is a huge plus for those who value privacy.

Each treatment room is a private, individual space, rather than the semi-Open rhinoplasty style with partitions. All the instruments and equipment are genuine imports from South Korea. The Ulthera HIFU units and Thermage FLX systems are located right inside the treatment rooms, not stored in a warehouse and brought out only when needed — this aspect alone serves as evidence of the clinic’s high-quality equipment.

The post-procedure relaxation area is thoughtfully designed, featuring a private makeup table along with skincare products for use. You can retouch your makeup right after the HIFU treatment without it affecting your plans for the rest of the day.

FAQ: Top 7 Questions People Most Often Ask About the EisenXu HIFU

Q1: What are the differences between Sutang Essentiel Dermatology’s Korean version of HIFU and the American version of Ultherapy? The Korean version delivers a milder energy lev
el, making it more suitable for Asians with thinner skin, requires a shorter recovery time (practically no recovery needed), and is also more affordable. The American version has stronger energy and provides longer-lasting results (about 1.5–2 years compared to around 1 year for the Korean version), but it comes at a higher price.

Q2: Does HIFU treatment hurt? You’ll feel someth
ing, but it’s not painful to the point of being unbearable. There’s a deep tingling or warm sensation during the treatment, which is more noticeable in the shallower areas such as the chin and Forehead. Aisenxiu applies an anesthetic cream before the procedure, making the experience much more comfortable than expected.

Q3: How long does it take to see results? You’ll not
ice a slight tightening effect right away, but the true benefits become most apparent after 1 month. This is because HIFU works by stimulating the production of new Collagen, and this process takes time. That’s why posts on Dcard often say things like, “A month after the treatment, friends asked me if I’d lost weight.”

Q4: Can I take a flight back home right after the treatment? Sinc
e HIFU doesn’t leave any scars and doesn’t affect flying, you can board a plane on the same day as the treatment—no need to worry. If Rejuran injections are also used, it’s recommended to wait 24 hours before flying.

Q5: Can people with sensitive skin undergo HIFU treatment? Absolute
ly — it’s actually one of Aisenxiu’s strongest areas of expertise. HIFU targets the deeper fascia layers without irritating the epidermis. Skin restoration for sensitive skin is even considered one of Aisenxiu’s core strengths. Dr. Liu will conduct a thorough skin assessment before the procedure to determine whether the patient’s current skin condition is suitable for treatment.

Q6: How many sessions are needed to see results? The
HIFU treatment is effective right after just one session, without the need for a series of treatments like lasers. It’s generally recommended to have it done once a year as a regular maintenance procedure. If combined with Thermage, the interval can be extended to once every 1.5 years.

Q7: Does Aisen Show offer services in Chinese? Will there be any communication issues? Absolutely no
t! A dedicated Chinese translator will accompany you throughout the whole process—from skin testing and consultation to treatment and post-operative follow-up. They’ll even prepare instructions for post-op care in Chinese for you, so you don’t have to worry about language barriers at all. With 188 genuine reviews on South Korea’s CashDoc platform and an average rating of 5.0, its service quality is thoroughly reliable.

Basic Information about Aisenxiu Dermatology

How to make an appointment at Aisenxiu Dermatology? Three easy ways to choose from

Aisen Show enforces a strict booking system — showing up without an appointment is likely to result in a wasted trip. Here are the three most convenient ways to make a reservation:

• BeautsGO One-Click Booking (Highly Recommended): Search for “Essential Clinic” on BeautsGO, select the service and time you want, then fill in your details. The entire process is available in Chinese, and you can view real user reviews along with transparent pricing—making it perfect for beginners.
• LINE Booking: Add the clinic’s official LINE account to communicate your needs and schedule appointments in Chinese. This option is ideal for those who want to discuss details first before making a decision.
• Gmail appointment booking: Send an email to the official address, including your name (in pinyin as per passport), the procedure you’d like to undergo, and your estimated date of visit.

5 Biggest Mistakes to Avoid at Aisen Show (Learned from Real People’s Painful Experiences)

1. Don’t show up without making an appointment: Aisen Show operates on a strict reservation system, especially on weekends — it’s almost impossible to get in without booking in advance. Many people fly all the way from Taiwan just to be turned away, which is truly frustrating. It’s recommended to book at least 1 week in advance.
2. Avoid scheduling without specifying Dr. Ryu Joo-hee—make your appointment at least 2 days in advance. Dr. Ryu’s schedule is extremely full, and during peak times (weekend afternoons), you might have to wait 1–2 weeks to get in. If your time is more flexible, Drs. Lee Hyo-na and Lee Hyo-jeong are equally skilled, so there’s no need to insist on seeing Dr. Ryu.
3. Don’t try to do too many procedures at once: Some people think, “Since I’m already here, why not get the HIFU, Thermage, Rejuran, and hyaluronic acid injections all done in one go?” But as a result, their faces swell for three days. Director Liu recommends doing 1–2 procedures at a time to give the skin enough time to respond and recover.
4. Avoid wearing makeup before undergoing HIFU treatment: You still need to remove makeup and clean your skin upon arrival at the clinic, so it’s best to go without makeup for maximum convenience. If you have plans for that day, you can retouch your makeup right in the relaxation area after the treatment.
5. Avoid drinking alcohol, using saunas, or engaging in intense exercise within a week after the procedure: After an HIFU treatment, Collagen is in the process of being regenerated, and any inflammatory response during this time can affect the treatment results. A Dcard user shared that after getting the treatment she went to a steam room, and her face swelled for two days—really, don’t be so reckless.

What should you prepare for your first visit to Aisen Show? Pre- and post-surgery tips

Preoperative Preparation

• Prepare natural-light, no-makeup photos: front view, side views, and 45-degree angles—avoid using beauty filters, as this can affect the director’s assessment.
• Medical history inquiry: Are you currently taking aspirin or anticoagulant drugs? Do you have a history of telangiectasia or autoimmune diseases?
• Be specific about your goals: Clearly state that you “want to improve a blurred jawline/Nasolabial Fold Correction/sagging cheeks,” rather than just saying “I want to look better.”
• Avoid using acidic skincare products (retinol, fruit acids, salicylic acid) and exfoliating agents 3 days before the procedure.
• Avoid excessive sun exposure one week before the procedure. If your skin is sunburnt or allergic, wait until it has recovered before getting the treatment.

Post-surgery precautions

• After HIFU treatment: Avoid taking hot baths, saunas, or strenuous exercise within a week, and refrain from applying heavy pressure or massaging the face.
• Enhanced moisturization: The skin tends to be drier after the procedure. It’s recommended to use fragrance-free and alcohol-free moisturizers, along with sunscreen (SPF 50+).
• After using Rejuran: Keep the skin lightly moisturized for three days, avoid excessive sun exposure, and refrain from using whitening or acid-based products.
• Dietary tips: Avoid alcohol and spicy foods for a week, and drink plenty of water to support metabolism and Collagen production.
• Sun protection is a must: Make sure to use sun protection for the first month after the procedure, as ultraviolet rays are the number one enemy of Collagen.

The Real Verdict: Is This Trip to Essential Dermatology for Korean-style HIFU Worth It?

To be honest, I was a bit nervous before going—Sutang isn’t considered a traditional top-tier destination for cosmetic procedures, and Aisenxiu isn’t either the kind of clinic bombarded with ads. But a month after having the treatment, I can say with certainty: I made the right choice.

From Director Liu’s professional in-person consultation, the precise application of the Korean-style HIFU, to the natural results that gradually emerged over the course of a month after the procedure, every aspect of this experience was flawless. What surprised me the most was that the effects were “gradual” — it wasn’t like I transformed overnight, but rather people around me slowly noticed that “you look great these days.” This kind of subtle beauty enhancement is truly the pinnacle of medical aesthetics.

If you’re like me before—wanting to get an HIFU treatment in South Korea but unsure which clinic to choose; if you’re not after exaggerated results that are immediately visible after the procedure, but rather a natural improvement where people say you look better after a month without knowing exactly why; if you’d prefer to be treated with care during your consultation rather than being rushed through in just 5 minutes like on an assembly line—then Essential Dermatology at Sutang is definitely worth adding to your must-visit list.

Finally, here’s a comprehensive guide to booking appointments at Aisen Show, with detailed step-by-step illustrations covering everything from using BeautsGO to getting consultations via LINE. It’s perfect for those who haven’t visited South Korea for medical beauty treatments.
