Ulfacial System: Customized Multi-Frequency Skin Care

Ulfacial at Le.J Plastic Surgery uses 1, 3 and 10 MHz ultrasound across 15 customized programs, in solutions of six to twelve minutes, with no recovery time.

Ulfacial System: Customized Multi-Frequency Skin Care

Ulfacial System Explained: Customized Multi-Frequency Skin Care Programs

Medically reviewed by Dr. Kim Ji Sun, M.D., Ph.D., Board-Certified Otolaryngologist

Ulfacial is a non-invasive skin-care system at Le.J Plastic Surgery built around high-density ultrasound delivered at more than one frequency. Rather than a single fixed facial, it offers 15 customized programs selected according to your skin condition and the area being treated, with each solution taking approximately six to twelve minutes. Its distinctive role at the clinic is that it is used before and after other treatments as much as on its own — which makes it less a standalone procedure than a piece of infrastructure around the rest of the menu.

What "multi-frequency" actually means here

Ultrasound at different frequencies penetrates to different depths. Lower frequencies reach further into tissue; higher frequencies concentrate their effect nearer the surface.

Le.J Plastic Surgery's Ulfacial uses high-density ultrasound at 1, 3 and 10 MHz. Having three available rather than one is what allows a single system to address concerns that sit at different levels of the skin — surface texture and barrier condition are not the same tissue problem as reduced elasticity, and treating them with identical settings would be treating them badly.

On top of frequency, three further variables are adjusted for each program: the intensity, the treatment time, and the area covered. Le.J Plastic Surgery selects the program according to your skin condition and the region being treated, which is the sense in which the treatment is customized rather than merely offered in variants.

Fifteen programs, and why the number matters

Le.J Plastic Surgery's Ulfacial offers 15 customized programs based on skin condition and treatment area.

A large program set is only useful if someone is choosing between them on evidence, which is why the assessment step is the part to pay attention to rather than the number itself. The concerns the system is intended for are specific: skin aging, skin problems, reduced elasticity, dryness, rough skin, increased wrinkles, a weakened skin barrier, and the wish for firmer skin along with body-line care.

That list spans two quite different categories — the condition of the skin as a surface, and its firmness as a structure. A program set of that size exists because those are not addressed identically.

Where Ulfacial sits: before and after other treatments

This is the part that distinguishes Ulfacial from a conventional facial, and it is worth understanding before deciding whether it belongs in your plan.

Le.J Plastic Surgery describes Ulfacial as a pre-care solution used before lifting treatments, focused on skin regeneration, soothing, and the delivery of skincare substances. It describes the same system as post-care afterward, with the same focus. The system is designed to support skin around other procedures rather than to compete with them.

The Ulfacial program also includes optional booster care using ingredients such as niacinamide, PDRN, hyaluronic acid, glutathione, NMN, adenosine, and vitamin capsules, selected as part of the program rather than applied uniformly.

Ulfacial can be used on its own, or selected together with the clinic's THOR facial and HI facial systems. Those three form one treatment program with different underlying technologies: Ulfacial provides high-density ultrasound care, THOR facial provides Toroidal radiofrequency care, and HI facial provides HIFU care. Ulfacial can also be combined with various lifting devices.

Wrinkles: which kind are you treating?

Not all lines respond to the same thing, and this is one of the more useful distinctions to carry into a consultation.

The American Society of Plastic Surgeons separates static wrinkles from dynamic wrinkles — the first visible when the face is at rest, the second appearing with expression and movement. That same organization attributes declining skin tone to elastin and collagen fibers that have weakened.

Increased wrinkles are among the concerns Ulfacial is intended for, and knowing which kind predominates in your face helps set a realistic expectation about what a skin-care program can and cannot do for them.

How often, and for how long

Le.J Plastic Surgery describes a single Ulfacial session as providing effective care in itself, while recommending weekly treatment across ten or more sessions for consistent satisfaction with appearance.

Each Ulfacial solution takes approximately six to twelve minutes, which is short by the standards of aesthetic treatment and is what makes a weekly cadence practical rather than burdensome.

The two statements together describe a maintenance treatment rather than an event. For anyone weighing it, the honest framing is that one session is worth having and a course is what the recommendation is built around — and a course of ten weekly sessions is a commitment best planned deliberately rather than started on impulse.

Downtime: none, and what that is worth

Ulfacial uses non-invasive technology and allows an immediate return to daily activities with no recovery period.

That profile is typical of the non-invasive category generally. The American Academy of Dermatology describes non-invasive skin tightening and rejuvenation procedures as producing gradual results with little or no downtime, as being safe for people of all skin colors, and as mostly taking an hour or less.

Two of those points deserve emphasis. Gradual is the trade the category makes: you accept a slower, subtler change in exchange for not having an operation. And safe across skin colors is a meaningful advantage for ultrasound-based and similar non-invasive treatments, given that this is precisely where some other technologies require considerably more caution.

Skin as a surface, and skin as a structure

Reading the list of concerns Ulfacial addresses, two different things are being described, and separating them helps you judge whether the treatment matches your complaint.

The surface. Dryness, rough texture and a weakened skin barrier are questions about the outermost layer — how well it holds water, how smooth it feels, how effectively it keeps irritants out. The pre-care and post-care roles around lifting treatments sit mostly here: skin regeneration, soothing, and the delivery of skincare substances.

The structure. Reduced elasticity and the wish for firmer skin are questions about what lies beneath that surface, where collagen and elastin do their work.

Most people arrive with some of both, which is why a program set spanning several frequencies and adjustable intensities makes more sense for this kind of treatment than a single fixed protocol would. It is also why the assessment matters more than the program count: what you want from the consultation is a clear statement of which of the two is dominant in your skin, and which program follows from that.

If your main concern is firmness rather than surface condition, it is worth asking directly how the plan divides between the two, and whether a lifting treatment belongs alongside the skin-care course rather than after it.

Safety and sensible expectations

A cosmetic treatment is a medical procedure. The American Academy of Dermatology's framing is that cosmetic treatments carry risk like any other medical procedure, and that asking questions beforehand is part of lowering that risk — a posture that applies to a non-invasive program as much as to surgery.

Practically, that means the consultation is where a skin-care program earns its value: the program is selected on your skin condition and the area concerned, and the frequency, intensity and treatment time are set from that assessment rather than from a standard menu.

Protecting what the program builds

A skin-care course is working against the same forces that made it appealing.

The MedlinePlus skin-aging page, sourced to the NIH National Institute on Aging, records two changes that run underneath everything a skin-care program is trying to improve: skin grows thinner and loses fat as the years pass, and sunlight ranks among the major causes of skin aging. Neither pauses while a course of treatment is under way. A weekly program running ten weeks or more is a long stretch of time to leave the second of those unaddressed, and it is the one you can do something about between appointments.

Sun protection is not an add-on to a skin program. It is the part of the plan you control between appointments.

Where it fits in the clinic's wider menu

Le.J Plastic Surgery works across five service categories: rhinoplasty and nose surgery; facial lifting and anti-aging; fat transfer and facial volume restoration; regenerative and stem cell therapy; and non-surgical skin rejuvenation. Ulfacial sits in the last of those, and connects to the second through its pre- and post-care role around lifting treatments.

MedlinePlus notes that removing facial wrinkles and creases is among the aims cosmetic procedures commonly address, so the underlying goal is a familiar one. What differs between the clinic's options is how invasive the route is and how long the result takes to appear.

If you are traveling and want to know whether a short course fits the time you have, that is a question worth settling before you book flights. Online consultations are requested via the contact page. Individualized planning at the practice is described on the about page.

Frequently Asked Questions

What do the different frequencies do?

Ultrasound at different frequencies reaches different depths in the skin. Le.J Plastic Surgery's Ulfacial uses high-density ultrasound at 1, 3 and 10 MHz, which is what allows one system to address concerns sitting at different levels rather than treating everything at a single depth.

How long does a session take?

Each Ulfacial solution takes approximately six to twelve minutes. The program, along with the frequency, intensity and treatment time, is adjusted according to your skin condition and the area being treated.

How many sessions are recommended?

Le.J Plastic Surgery describes a single session as providing effective care, and recommends weekly treatment across ten or more sessions for consistent satisfaction with appearance. The short session length is what makes that cadence manageable.

Is there any downtime?

No. Ulfacial uses non-invasive technology and allows an immediate return to daily activities. The American Academy of Dermatology describes non-invasive rejuvenation treatments generally as involving little or no downtime and as suitable for people of all skin colors.

Can Ulfacial be combined with other treatments?

Yes. It is used as pre-care and post-care around lifting treatments, can be combined with various lifting devices, and can be selected together with the clinic's THOR facial system, which provides Toroidal radiofrequency care, and its HI facial system, which provides HIFU care.

What are the booster ingredients for?

The Ulfacial program includes optional booster care using ingredients such as niacinamide, PDRN, hyaluronic acid, glutathione, NMN, adenosine and vitamin capsules. Which of them is included is part of the program selected for your skin rather than a fixed addition.

What concerns is Ulfacial intended for?

Le.J Plastic Surgery lists skin aging, skin problems, reduced elasticity, dryness, rough skin, increased wrinkles, a weakened skin barrier, and the wish for firmer skin along with body-line care. Which program suits which concern is decided after your skin has been assessed.
