Ulfacial

Ulfacial in Seoul at Le.J Plastic Surgery

Medically reviewed by Dr. Kim Ji Sun, M.D., M.S., Ph.D., Board-Certified Otolaryngologist · Le.J Plastic Surgery, Gangnam-gu, Seoul

Ulfacial is a non-invasive aesthetic skincare system that uses high-density ultrasound at 1, 3 and 10 MHz. It offers 15 programmes customised according to skin condition and treatment area, and it can be used independently or alongside lifting treatments. At Le.J Plastic Surgery in Gangnam-gu, Seoul it sits within the clinic's Skin Care range, and it is performed personally by Dr. Kim Ji Sun, the clinic's founder and Medical Director and the listed performing doctor for the parent Skin Care specialty.

One boundary is worth setting before anything else, because it decides whether this is the right appointment to book. Ulfacial focuses on skin condition and skincare support rather than primarily lifting sagging tissue. That is the clinic's own description, not a hedge — if the concern is descended tissue rather than skin quality, the honest answer is a different treatment, and the clinic holds several of those.

What Is Ulfacial?

Ulfacial is an ultrasound-based skincare system in which high-density ultrasound at three frequencies — 1, 3 and 10 MHz — is applied to the skin using one of 15 programmes chosen for the patient's skin condition and the area being treated.

• Three operating frequencies and 15 programmes, with frequency, intensity and duration adjustable.

• Stated aims are skin elasticity, hydration, texture, pore appearance, skin tone and barrier strength.

• Each individual solution takes approximately 6–12 minutes.

• It is non-invasive, generally needs no anaesthesia, and generally requires no recovery time.

• It can be used alone, or before and after lifting treatments to support skin regeneration and soothing.

The multi-frequency design is the part worth understanding, because it is what the programme selection is actually selecting. Different frequencies behave differently in tissue, which is why the device offers a menu rather than a single setting, and why the clinic adjusts frequency, intensity and duration to the individual rather than applying one protocol to everyone.

The clinic's own stated description of this treatment is the bound of what is asserted here: that Ulfacial is a non-invasive aesthetic skincare system using high-density ultrasound at 1, 3 and 10 MHz, that it offers 15 customised programmes, that it is designed to support skin quality, and that it may be used before and after lifting treatments. No efficacy figure, no comparison and no regulatory status beyond that is claimed on this page.

Who Performs Ulfacial at Le.J Plastic Surgery

Dr. Kim Ji Sun, M.D., M.S., Ph.D.
Board-certified Otorhinolaryngologist

Ulfacial is performed personally by Dr. Kim Ji Sun, the clinic's founder and Medical Director and the listed performing doctor for the parent Skin Care specialty.

Dr. Kim is a board-certified otolaryngologist who earned an M.D., a Master's degree and a Ph.D. from Dankook University College of Medicine, completed internship and residency at Dankook University Hospital, trained as a Clinical Fellow in the Department of Otorhinolaryngology at Asan Medical Center, and has served as a Guest Professor at Stanford University School of Medicine in the United States.

Dr. Kim's most recent relevant academic activity is a 2026 lecture on non-surgical facial rejuvenation and closed rhinoplasty at the 12th meeting of the Korean Academy of Facial Plastic and Reconstructive Surgery, where Dr. Kim is a regular member and serves on the academic, public-relations and international committees.

Le.J Plastic Surgery is a single-doctor clinic, so the surgeon who assesses you is the surgeon who treats you. That matters more than usual for an energy-based treatment, because the clinically interesting decisions here are made at the console rather than during the application: the treatment programme is selected according to skin condition and treatment area, and frequency, intensity and duration are individually adjusted.

Who Is a Good Candidate for Ulfacial?

Suitable candidates:

• Patients concerned about skin aging or reduced elasticity.

• Patients with dryness, rough texture, a weakened skin barrier, dullness or visible pores.

• Patients with mild sagging and fine lines.

• Patients seeking skin preparation or recovery support around a lifting treatment.

Who should avoid or postpone, or needs assessment first:

• Patients with significant skin concerns or medical conditions that could affect treatment safety, who should be individually assessed by a qualified medical professional before proceeding.

• Patients with open wounds or active skin lesions in the treatment area, which should not be treated over without medical assessment.

• Patients with implanted electronic devices, or metal implants in the treatment area, which must be disclosed beforehand.

The clinic does not publish an exclusion list of its own beyond these, so none is invented here. Suitability depends on skin condition, medical history and treatment requirements, and the sorting question is still the one from the top of this page: skin quality, or sagging tissue.

What to Expect: Procedure, Recovery, and Results Timeline

The appointment is short and uneventful by design. The appropriate programme is selected based on skin condition and treatment area, high-density ultrasound is then applied to the targeted area using the selected settings, and each individual solution takes approximately 6–12 minutes.

Stage	What the clinic states
Session length	Approximately 6–12 minutes per solution; one session per visit
Anaesthesia	Not required; the treatment is non-invasive
During treatment	Mild warmth, tingling or temporary discomfort
Immediately after	Normal activities can resume immediately
Recovery	No recovery period is generally required; temporary redness or sensitivity may occur
First results	Vary with skin condition, settings and number of sessions
Course	A course of weekly treatments may be recommended to support consistent improvement
Final result	Described by the clinic as apparent after approximately 3 to 4 months

The gap between "no downtime" and "a result in three to four months" is the honest shape of this treatment, and it is worth planning around rather than being surprised by. A single session is comfortable and leaves nothing to recover from; the outcome the clinic describes belongs to a course run over time. For an international patient that mainly affects booking: for Ulfacial alone an extended stay in Korea may not be necessary, because the treatment is non-invasive and generally requires no recovery time, but if you plan multiple sessions the recommended schedule and your travel itinerary should be discussed with the clinic before booking. Flying is generally possible after treatment for the same reason, though the clinic should confirm suitability for air travel, particularly if a more intensive energy setting was used.

Aftercare is correspondingly light: gentle skincare, adequate moisturisation and sun protection may help maintain skin comfort, and irritating skincare products are best avoided if the skin feels sensitive. If something feels wrong after returning home, patients can reach the clinic's English-speaking counselling manager by phone or email.

Combining Ulfacial with Other Treatments

• Lifting treatments — the clinic states Ulfacial may be used alone or before and after lifting treatments, to support skin regeneration and soothing.

• THOR facial — the clinic's toroidal radiofrequency care, named as a possible combination.

• HI facial — the clinic's HIFU care, named as a possible combination.

• Optional booster care — niacinamide, PDRN, hyaluronic acid, glutathione, NMN, adenosine and vitamin capsules, where clinically appropriate.

The clinic publishes no per-procedure pages for several of these, so they are listed without links rather than linked to pages that do not exist.

The first item is the one that changes how this treatment is usually used. Positioned before and after a lifting procedure, Ulfacial is doing preparation and soothing work rather than competing with the lifting device, which is a different role from the standalone skin-quality course described above. Both are legitimate uses of the same system, and which one applies to a given patient is settled at assessment.

Safety, Precision, and Clinic Standards

Le.J Plastic Surgery is a Registered Medical Institution for Attracting Foreign Patients, certified by the Ministry of Health and Welfare in compliance with the Medical Overseas Expansion and Foreign Patients Attraction Act. This is a registration for treating international patients; it is not an accreditation of any treatment in this category.

The clinic has not published a risk-reduction protocol specific to this procedure, so none is described here in its place.

The reported effects are mild and short-lived: temporary redness, warmth, tenderness or sensitivity, with mild warmth, tingling or brief discomfort during the session itself. Beyond those, the clinic's statement is appropriately cautious rather than reassuring — less common adverse reactions are possible with energy-based treatments. That sentence is doing real work. Any device that delivers energy into tissue can do so unevenly if the settings or the contact are wrong, which is why the disclosure list before treatment is specific about things that change how energy behaves: open wounds, active skin lesions, implanted electronic devices and metal implants in the treatment area.

Those four disclosures are not a formality, and two of them are device-specific rather than skin-specific: an implanted electronic device or metal in the treatment field is a reason to plan around an area, not a box to tick. The same logic explains why the clinic adjusts frequency, intensity and duration per patient rather than running a fixed protocol — the settings are the safety margin as much as they are the treatment. What the clinic has not published is a figure of any kind for this service: no session counts, no outcome data, no adverse-event rate. Those are absent here because they are absent there.

Le.J Plastic Surgery publishes neither case volumes nor complication rates for this procedure, and this page claims neither. That is a fair question at consultation, as is the one worth asking any provider of an energy-based treatment: how many of these they have performed, on what range of skin types, and what follow-up to expect if something changes afterwards.

Any treatment in this category is delivered by a medical device, and on that category the U.S. Food and Drug Administration states that a procedure may not always give you the results you want, the effects may be temporary, and there are risks involved when using any device, including aesthetic devices.

The Bottom Line

• Ulfacial is a non-invasive high-density ultrasound skincare system operating at 1, 3 and 10 MHz with 15 adjustable programmes.

• It targets skin condition — elasticity, hydration, texture, pores, tone and barrier strength — rather than primarily lifting sagging tissue.

• Each solution takes approximately 6–12 minutes, with no recovery period generally required.

• A course of weekly sessions may be recommended, and the clinic describes the final result as apparent after approximately 3 to 4 months.

• It can be used before and after lifting treatments, where its role is preparation and soothing rather than lifting.

• The clinic holds several lifting technologies, so the assessment can honestly end somewhere other than this one.

Frequently Asked Questions

Will Ulfacial lift my face? That is not what it is for. The clinic's own description places it on skin condition and skincare support rather than primarily on lifting sagging tissue. It can be used before and after a lifting treatment, where its role is preparing the skin and soothing it afterwards. If the concern is descended tissue, the clinic offers lifting options and the assessment should end with one of those instead.

What does a session feel like, and is there any downtime? Mild warmth, tingling or temporary discomfort during treatment, and nothing to recover from afterwards. No recovery period is generally required and normal activities can resume immediately, although temporary redness or sensitivity may occur. Each individual solution takes approximately 6–12 minutes.

How many sessions will I need, and when will I see the difference? Results vary with skin condition, treatment settings and the number of sessions, so there is no single answer. A course of weekly treatments may be recommended to support consistent improvement, and the clinic describes the final result as apparent after approximately 3 to 4 months. How long it holds depends on individual response and maintenance care.

What do the three frequencies and 15 programmes actually change? They are what is being selected for you. The programme is chosen according to skin condition and treatment area, and frequency, intensity and duration are then individually adjusted. In practice that means two patients treated on the same device on the same day may receive quite different settings, which is why the assessment precedes the booking rather than the other way round.

What must I tell the clinic before treatment? Open wounds, active skin lesions, implanted electronic devices and metal implants in the treatment area. All four change how the treatment should be planned, and areas with open wounds or active lesions should not be treated over without medical assessment. Existing skin concerns and relevant medical conditions belong in the same conversation.

I have had an ultrasound-based treatment before. Does that rule this out? Not in itself, and it is a question the clinic expects. Previous ultrasound-based treatment is part of the history reviewed at assessment, along with your current skin condition and treatment requirements, and suitability is decided from that rather than from the fact of a previous session.

Can I fly home straight after a session? Flying is generally possible after treatment, because Ulfacial is non-invasive and requires no recovery period. The clinic should confirm suitability for air travel, particularly if a more intensive energy setting was used. If you intend to complete a course of sessions, agree the schedule with the clinic before booking flights.
