When it comes to choosing a Dermatology clinic in Seoul, the question of “who will perform the procedure for you” is actually far more important than many people realize.
If the HIFU treatment is performed at a deeper or shallower depth, the results will be significantly different. Whether the Rejuran injection is administered at the correct layer determines whether it will have a hydrating effect or simply be a waste of effort. Even with the same genuine Thermage equipment, the results achieved by an experienced practitioner can be vastly different from those obtained by a novice.
So this time, I would like to introduce someone in detail – the Chief Executive Officer and Managing Director of Essential Clinic: Yoo Juhui / 유주희.

Essential’s unique technique for applying Rejuran
Liu Zhouxi is the Chief Executive Officer and Chief Physician of Aisenxiu Essential Clinic, and also serves as the person responsible for ensuring the high quality of medical services provided by the entire clinic.
Her background can be described by several key terms:
- 20 years of clinical experience: She belongs to the senior category among the deans of Dermatology in South Korea. These 20 years mean that she has dealt with a wide range of real cases involving various skin problems, ranging from common skin issues to anti-aging treatments, thus possessing extensive technical expertise.
- She refuses to follow a standardized process: In her approach to medical aesthetics, the concept of “standardized packages” simply doesn’t exist. Everyone’s skin condition, lifestyle, and budget are unique, so the treatment plans must also be tailored accordingly.
- Precise Anti-Aging: Her core philosophy is “precision” – avoiding excess, being cautious, and ensuring sustainability. By choosing the most appropriate treatments, she aims to achieve the most natural results possible.

The experience of using Essentiale Ulthera in the aesthetic medicine industry
Many people have a misconception about anti-aging treatments: the more procedures and the more expensive the equipment, the better the results will be.
However, Director Liu Zhouxi holds exactly the opposite view.
In the official introduction of Essential Clinic, there is a phrase that appears repeatedly: “We do not regard cosmetic medicine as a ‘tool for quickly changing one’s appearance,’ but rather see the skin as a system that requires understanding, respect, and ongoing care.”
Putting this concept into practical action means:
Step 1: VISIA Skin Analysis – Accurately detect pigment deposition and collagen loss beneath the skin surface, relying on data rather than mere “feelings”.
Step 2: Personal consultation by the director (≥15 minutes) — Based on the test results, the director will provide a customized treatment plan and clearly explain the function and expected outcomes of each treatment option.
Step 3: One-on-one follow-up throughout the entire process – from the initial consultation to the treatment and follow-up examinations, the same doctor will be responsible for everything, with no changes in personnel in between.
The advantage of this approach is that the clinic director has a thorough understanding of your skin condition and can adjust the treatment plan accordingly based on your response after each session.
Essential’s Personal and Honest Postoperative Reviews
Essential Clinic has a total of four chief scientific officers. In addition to Liu Zhouxi, they also include:
Yi Hyo-na / 이효나 — Director: Specializes in professional skin care, with extensive experience in injectable treatments and instrumental anti-aging therapies.
Yi Hyo-jung / 이효정 — Director: Specializes in the diagnosis and treatment of skin diseases using laser therapies.
Yi En-young / 이은영 — Director: An expert in Rejuran projects, Rejuran PN is one of her areas of expertise.
What these four individuals have in common is their solid background in dermatology; they are certainly not the kind of people who just “jump into the job after attending a quick training course.” Moreover, the entire clinic places great emphasis on serving foreign tourists, offering support for communication in multiple languages such as Chinese, English, and Japanese.

A Comparison of Essential by Aisen Show with Other Clinics
Based on the project offerings of Essential Clinic and the areas of expertise of Director Liu Zhouxi, the following services can be expected to offer relatively reliable experiences when handled by her or her team:
The American ultrasound device Ulthera: It acts directly on the SMAS fascia layer, and the official genuine probes come with anti-counterfeiting codes for verification. The clinic director will adjust the treatment parameters according to each patient’s facial contours to avoid the problem of “the same number of treatments but different distributions.”
Thermage FLX (Phoenix Radio): Also using genuine equipment and probes, this treatment comes with a comprehensive post-treatment care package that includes LDM therapy, Lifting masks, and regenerative lasers, all designed to reduce post-procedure dryness and redness.
Rejuran PN: This is one of Dr. Lee Eun-yeong’s specialty treatments. The combination of Rejuran PN 2CC, a soothing facial mask, White Jade Needles, and a rejuvenating laser treatment makes this package one of the most popular options at the clinic.
V-LINE Thread Lifting: A targeted Lifting treatment designed for those with blurred contours in the lower face and sagging Apple Zone.

Prices and Package Options of Aisen Show Essential
After visiting the “assembly line” clinics in South Korea, many people often complain about the following issues:
- The consultant was overly aggressive in his sales efforts, completely losing control of the budget.
- It wasn’t the director himself who performed the procedure; it was a technician.
- The same approach applies to everyone, without any customization.
- No follow-up was done after the procedure, and when problems occurred, no one was available to help.
At Essential Clinic, there are clear mechanisms in place to address these issues:
No sales pressure: The principle of Liu Zhouxi’s team is to “first understand the customer’s needs” rather than “immediately recommend the most expensive packages.” Amanda’s Google review is the best proof of this: “I clearly stated that my budget was limited and asked not to be pressured into making purchases, and she actually took that request into consideration.”
The dean personally performs all treatments: Every procedure is carried out directly by the certified dean himself, so there is no possibility of “technicians doing the work on behalf of him”.
Postoperative follow-up: Within 7 days after the procedure, a dedicated staff member will call you to answer any questions you may have regarding postoperative care. This is something that is almost impossible to achieve at “assembly-line” type clinics.
Essential Post-Treatment Care Recommendations from Eisen Show
It is necessary to confirm in advance the time when President Liu Zhouxi is available for consultations. It is recommended to make an appointment through the following methods:
Method 1: One-click reservation through BeautsGO – On the BeautsGO platform, select “Aisenxiu Dermatology”, fill in the desired treatment and time, and a Chinese customer service representative will assist you with the arrangement.
Method 2: Add the Chinese manager’s WeChat —— Contact the Chinese manager of the clinic directly and communicate one-on-one to request an appointment with Director Liu Zhouxi.
Method 3: Telephone/Message on the Platform – Make an appointment through a third-party platform and indicate “Request to see Director Liu Zhouxi”.
It is recommended to make a reservation 3-5 days in advance, as weekends and holidays tend to be more busy.
