Gangnam Ultherapy Guide: Microfocused Ultrasound (MFU-V) Principle, Effects & Safety | Cellinique

If You're Considering Ultherapy in Gangnam

If you've started to feel that your skin isn't as firm as it once was, you've probably come across the name "Ultherapy" at least once. It's often mentioned as a lifting option that doesn't require surgery, but it's surprisingly hard to find information that calmly lays out "exactly how it works and how long the results last" and "where and how you should get a consultation in Gangnam."

In this article, we've organized how Dr. Kim Gun-woo, Medical Director of Cellinique on Dosan-daero in Gangnam, consults on Ultherapy, the order in which the procedure is carried out, and how he explains its effects and safety. If you're curious about comparisons with other lifting procedures, take a look at our lifting procedure comparison guide or the Ultherapy treatment information page as well.

3-Line Summary

1. Ultherapy is a non-invasive lifting procedure that delivers microfocused ultrasound with visualization (MFU-V) into the deeper layers of the skin (1.5, 3.0, and 4.5mm) to stimulate your own collagen production without any incision.
2. The device first received 510(k) clearance from the U.S. FDA in 2009, and indications for the neck, under-chin, and décolletage were added later. (This is 510(k) clearance, not "FDA approval.")
3. Results appear not immediately after the procedure but gradually over a span of weeks to months, and both how long they last and how noticeable they are vary significantly from person to person. The specific plan is decided during your pre-procedure consultation at Cellinique on Dosan-daero in Gangnam.

1. What Is Ultherapy? The Principle of Microfocused Ultrasound (MFU-V)

Ultherapy is a non-invasive lifting procedure that uses microfocused ultrasound (MFU-V). Unlike lasers, which use light energy, Ultherapy delivers ultrasound energy concentrated at a set depth without touching the surface of the skin. That's why it's often introduced as "lifting without a scalpel."

Here's how it works. When ultrasound energy is concentrated at a set depth within the skin (typically 1.5mm, 3.0mm, and 4.5mm), small thermal coagulation points form at those spots. The 4.5mm depth in particular corresponds to the superficial musculoaponeurotic system (SMAS) layer — the very layer that is lifted and tightened in a facelift. These tiny thermal stimuli denature collagen and, over time, are reported to prompt fibroblasts to produce new collagen and elastin fibers. So Ultherapy is less of a procedure that "pulls things tight right away" and more of one that helps the skin rebuild its own elastic structure.

- MFU-V has been histologically reported to create thermal coagulation points at depths of 1.5mm (superficial dermis), 3.0mm (deep dermis), and 4.5mm (SMAS/platysma), denaturing collagen and prompting HSP47-positive fibroblasts to gather and generate new collagen and elastin fibers.
- The response is described as progressing in the order of transient inflammation → proliferation → remodeling, proceeding without damage to the epidermis.
- Changes appear gradually, and their degree and longevity vary from person to person.

That said, because collagen production proceeds slowly over time, this is not a procedure that is "completed on the day of treatment." It's more realistic to separate your expectations into the changes seen right after the procedure and those that unfold over the following weeks to months.

In One Line

It's a non-invasive lifting procedure that uses ultrasound thermal stimulation to help the deeper layers of the skin rebuild collagen. How it's carried out, whether it suits you, and how long it lasts differ from person to person and are decided during your pre-procedure consultation at Cellinique on Dosan-daero in Gangnam.

2. Ultherapy at a Glance

Item	Details
Method	Non-invasive lifting based on microfocused ultrasound (MFU-V) (no incision)
Working depths	Typically 1.5mm, 3.0mm, and 4.5mm (4.5mm is the SMAS layer)
Primary action	Stimulating self-generated collagen and elastin fibers via thermal coagulation points
Overseas certification	U.S. FDA 510(k) clearance (first in 2009 — brow lift, with neck, under-chin, and décolletage indications added later). ※ This is 510(k) clearance, not "FDA approval"
Anesthesia	Topical numbing cream, etc. (depending on the treatment area and extent)
Downtime	Generally on the shorter side, but temporary redness, swelling, and tenderness vary greatly between individuals
Pattern of perceived results	Gradual changes over weeks to months rather than right after the procedure; varies greatly between individuals
Longevity	Varies greatly between individuals and is not guaranteed (realistically explained during the pre-procedure consultation)
Consultation & procedure by	Dr. Kim Gun-woo, Medical Director, performs consultations and procedures directly
Location	Cellinique on Dosan-daero in Gangnam
Examples requiring careful review	Pregnancy or breastfeeding, active infection or wounds in the treatment area, a tendency toward keloids, metal implants or prostheses in the treatment area, etc. — assessed during the pre-procedure consultation

※ The above is general guidance, and whether Ultherapy is right for you and exactly how it would proceed can only be decided through a pre-procedure consultation. How you perceive the results and how suitable it is differ depending on your individual skin and health condition.

3. For Which Concerns Do We Consider Ultherapy Together?

Ultherapy isn't a procedure we recommend to everyone. In our consultations, we typically consider whether it might be an option for those who describe concerns like the following.

If You Have Concerns Like These

• Those bothered by sagging and reduced firmness along the cheeks and jawline
• Those concerned about laxity under the chin and around the neck
• Those who find surgery daunting but want to consider non-invasive firmness care
• Those thinking about the procedure within the framework of long-term skin care rather than a single result

Of course, having these concerns doesn't mean Ultherapy is always the answer. It simply means it's one of the options to review during a consultation. When sagging is significant or there's a lot of skin laxity, another approach may be more suitable, so whether it actually fits you is decided during the pre-procedure consultation based on your individual condition.

Conversely, We're Cautious in These Cases

• If you are pregnant, breastfeeding, or planning to be
• If there is an active infection, wound, or inflammation in the treatment area
• If you have a tendency toward keloids or hypertrophic scarring
• If there are metal implants or prostheses in the treatment area
• If severe or cystic acne is present in the treatment area

If even one of the above applies to you, please be sure to let us know in advance during the pre-procedure consultation. We'll confirm whether the procedure is possible and, if needed, help you consider other care options as well.

4. What Does the Process Look Like?

At Cellinique, we carry out Ultherapy in the following order. Because this is a procedure where the design of the energy delivery depth and area, along with recovery management, affects the outcome, we try to keep the process simple and stable.

1. Pre-procedure consultation + skin assessment — Dr. Kim Gun-woo personally reviews the degree of skin sagging, firmness, history of past procedures, and lifestyle habits. Whether Ultherapy is suitable is usually decided at this stage.
2. Area and depth design — We review which areas will receive energy at which depths (1.5, 3.0, 4.5mm), as well as combinations and sequencing with other procedures.
3. Anesthesia and preparation — Depending on the area and extent, we explain ways to reduce discomfort, such as topical numbing cream.
4. Procedure application — We deliver energy to the set depths while confirming the layers with ultrasound imaging. (The amount of energy, depth, and number of lines are designed individually to match the area and condition.)
5. Aftercare + next follow-up guidance — We separately provide post-procedure precautions, recovery checkpoints, and, if needed, the timing of your next follow-up.

💡 One Person's Story — Among those receiving it for the first time, some tell us, "Because I'd been told in advance that it takes time for collagen to build up, I didn't feel anxious even though the change right afterward wasn't dramatic." That said, recovery and the pattern of change vary greatly between individuals, so if you notice any change at all, please feel free to reach out to Cellinique.

5. How Do We Explain Results and Longevity?

The changes from Ultherapy aren't completed on the day of the procedure. Because it takes time for new collagen and elastin fibers to form, you'll usually observe changes gradually over a span of weeks to months.

💡 Fact-check ✓

Sources: PMC12374570 literature review (J Cosmet Dermatol 2025) · PMC6336023 (Kerscher et al., Clin Cosmet Investig Dermatol 2019)

- MFU-V's effects are delayed; clinical studies primarily evaluated outcomes at the 90-day and 180-day marks, and some studies reported sustained improvement out to 12 months or more.
- There are reports that elasticity indices increased significantly at 12 and 24 weeks after the procedure, but the degree of improvement is described as varying widely between individuals (a mix of mild to significant improvement).
- As a result, a uniform guarantee like "lasts several years" is difficult, and longevity and how noticeable it is vary from person to person.

That's why, at Cellinique, instead of definitive claims like "you'll look X years younger" or "it lasts X years," we work with you during the consultation to outline a realistic range of change you can expect for your own skin. Whether it's a one-time procedure or something to repeat over time within a care plan also differs depending on your individual condition.

6. How Do We Manage Downtime and Recovery?

Because Ultherapy involves no incision, downtime tends to be short, but given the nature of ultrasound thermal stimulation, temporary reactions can occur, and there are differences depending on your recovery capacity and lifestyle habits.

Reactions We Commonly Mention Right After the Procedure

• Temporary redness and a warm sensation in the treatment area
• Mild swelling and tenderness (often subsiding within a few days)
• Temporary tingling or a feeling of tightness, depending on the area
• Rarely, temporary bruising (which often resolves over time)

For a Few Days After the Procedure

• Please briefly avoid irritating cosmetics, intense heat (saunas, hot rooms), and strong massage
• Please apply thorough sun protection
• If you notice any change in your condition or skin, please feel free to contact Cellinique

The key point is that, since recovery patterns differ from person to person, it's important to go over the recovery process and follow-up schedule together in advance.

7. Safety Standards and Precautions

Ultherapy is, after all, a genuine medical procedure, so it's difficult to say there's no risk at all. Because the design of the energy delivery depth and area in particular affects both outcome and safety, Cellinique allows ample time for consultation, area design, and post-procedure follow-up.

Sources: U.S. FDA 510(k) medical device clearance information (accessdata.fda.gov, Ulthera, Inc.) · PMC6336023 (Clin Cosmet Investig Dermatol 2019)

- Ultherapy (the Ulthera System) is a microfocused ultrasound device registered with the U.S. FDA via 510(k) clearance (e.g., K121700 for neck and under-chin, K134032 for décolletage — Ulthera, Inc.). This is 510(k) clearance, not PMA "approval."
- There are reports that it did not significantly impair the skin barrier or physiological indices in clinical settings, although temporary swelling, redness, and the like may be observed.
- Rarely, pain, nerve stimulation, and temporary sensory changes may be reported, and whether they occur and to what degree vary from person to person.

Commonly Reported Reactions

• Temporary redness, swelling, and tenderness in the treatment area (mostly recovering within a few days)
• Rarely, bruising or temporary sensory changes (numbness, dulled sensation)
• Very rarely, temporary muscle weakness or nerve stimulation (usually recovering over time)

When You Should Contact Cellinique Immediately

• When severe swelling, heat, or redness in the treatment area persists
• Facial asymmetry or persistent sensory abnormalities
• Pain that progressively worsens
• Suspected allergic or abnormal skin reactions

What You Must Tell Us Before the Procedure

• Whether you are pregnant or breastfeeding (including if you are planning to be)
• A history of keloids or hypertrophic scarring
• A history of metal implants, prostheses, or filler treatments in the treatment area
• Whether there is active infection, wounds, or severe acne
• Other procedures you've had recently (the interval and sequencing may need adjusting)

The criteria for side effects, emergency response, contraindications, and infection control that apply to all procedures can be reviewed in detail on the Cellinique treatment safety information page. If you're considering Ultherapy, we recommend taking a look through it before the procedure.

Frequently Asked Questions (FAQ)

Q1. Is Ultherapy an FDA-approved procedure?

To be precise, it's a device that received FDA 510(k) clearance, not "approval." Ultherapy (the Ulthera System) first received 510(k) clearance from the U.S. FDA in 2009 for brow lifting, and indications for the neck, under-chin, and décolletage were added later. 510(k) clearance is a certification pathway that recognizes substantial equivalence to existing devices, and its process differs from PMA approval. That's why, at Cellinique, we explain it precisely as "FDA 510(k) clearance" rather than using the phrase "FDA approval."

Q2. When do Ultherapy's effects start to appear?

In many cases, changes appear gradually over a span of weeks to months rather than on the day of the procedure. This is because it takes time for new collagen and elastin fibers to form. However, the degree and timing of change vary considerably depending on your skin condition, age, and lifestyle habits, so please get a thorough explanation during the pre-procedure consultation about what you can expect for yourself.

Q3. How long do the results last?

Clinical studies reported sustained improvement at 90 and 180 days, and some out to 12 months or more, but it's described as varying widely between individuals. A uniform guarantee like "it lasts several years" is difficult. Since aging continues, whether to repeat it over time within a care plan is also decided together during the pre-procedure consultation based on your individual condition.

Q4. Does it hurt? How much downtime is there?

Given the nature of ultrasound thermal stimulation, you may feel a tingling or warm sensation during the procedure, so depending on the area and extent, we reduce discomfort with topical numbing cream and the like. Because there's no incision, downtime is generally on the shorter side, but temporary redness, swelling, and tenderness can occur, and recovery patterns vary between individuals.

Q5. Where in Gangnam can I get an Ultherapy consultation?

Cellinique is located on Dosan-daero in Gangnam. Dr. Kim Gun-woo personally handles everything from the pre-procedure consultation to area design, the procedure, and post-procedure follow-up. When choosing a clinic, though, rather than advertising slogans like "the best in Gangnam," we recommend comparing based on whether the doctor personally consults and performs the procedure and whether the area design and aftercare are consistent. For a consultation, please reach out at 02-6203-3434 or via KakaoTalk.

Q6. Can anyone get it? Are there cases that require caution?

If you are pregnant, breastfeeding, or planning to be; if there's an active infection or wound in the treatment area; or if you have a tendency toward keloids or have metal implants or prostheses in the treatment area, we review carefully. If any of these apply, please be sure to let us know during the pre-procedure consultation. Depending on the degree of sagging or skin laxity, another approach may be more suitable, so suitability is decided during the consultation.

Q7. What about the cost?

Because Ultherapy is a procedure whose design changes depending on the area, extent, number of lines, and combination with other procedures, the cost varies depending on your individual condition and the design. We provide precise guidance directly during the pre-procedure consultation. It's perfectly fine to come just for a consultation regardless of whether you proceed with the procedure, so please feel free to reach out at 02-6203-3434 or via KakaoTalk.

Closing

Ultherapy isn't a procedure to get just because it's famous — it's a lifting procedure that, for those who want to manage firmness and sagging non-invasively, is reviewed after a pre-procedure consultation and skin assessment. What matters isn't the name of the device, but whether its action actually fits your skin and your goals.

At Cellinique (on Dosan-daero in Gangnam), Dr. Kim Gun-woo personally handles everything from the first consultation to the procedure and post-procedure follow-up. If you're interested in Ultherapy, we recommend starting with a consultation where you can comfortably talk through your skin condition and care goals. You can find comparisons with other lifting procedures in our lifting procedure comparison guide, treatment details on the Ultherapy treatment information page, and our shared safety standards in the Cellinique treatment safety information.
