This is a procedure note for Double Chin Ultherapy: How does it refine the stubborn under-chin area that won't go away even with weight loss? at Beomgye(Opening Soon) KKEUT Korean Clinic.
Double Chin Ultherapy: The Principle of Refining the Underside of the Chin That Wouldn't Budge Even After Losing Weight?
You've probably experienced diligent dieting, only for your double chin to stubbornly remain.
The reason a double chin persists even after weight loss is that the skin and subcutaneous tissue in that area have already lost elasticity and sagged.
Double Chin Ultherapy approaches this by lifting the sagging structure itself.

The Mechanism by Which Ultherapy Refines a Double Chin
Ultherapy is based on HIFU (High-Intensity Focused Ultrasound) technology.
It concentrates ultrasound energy on a single point in the deep skin layer, heating only that spot to 65°C~70°C.
The key layer at this point is the SMAS layer.
The SMAS layer is a fascial tissue located between the skin and muscle, serving as the structural foundation that determines overall facial sagging.
When Ultherapy directly heats this layer, collagen fibers immediately contract, and then new collagen is regenerated over several months, resulting in a lifting effect.

The 4.5mm tip is primarily used for the double chin area.
This tip precisely focuses energy at a depth of 4.5mm from the skin surface, specifically targeting the SMAS layer.
Since it stimulates only the deep layers without affecting the surface skin, downtime is minimal, and a quick return to daily life is possible.

Why Ultherapy is Effective for Double Chins
Another reason why submental fat doesn't go away is reduced skin elasticity.
It's not the amount of fat itself that's the problem, but rather the skin sagging and volume accumulating below the jawline.
Double Chin Ultherapy stimulates the SMAS layer to lift the entire supportive structure of the skin, thus refining the jawline in a way different from simple fat removal.
Immediately after the procedure, there's an instant tightening effect, and the lifting is completed as new collagen is generated over 3 to 6 months post-procedure.

Indications are as follows:
It is effective for those with sagging under the chin due to reduced skin elasticity, those who still have a double chin after weight loss, and those who want to achieve a sharper jawline.
While the number of sessions and frequency vary depending on individual skin condition, many generally experience the effects after 1 to 2 treatments.
Since it's a treatment where collagen regeneration effects accumulate, combining it with maintenance treatments every 6 months to 1 year can help prolong the results.

Post-procedure care is not complicated.
It's best to avoid excessive heat stimulation (sauna, strenuous exercise, alcohol consumption) on the day of the procedure, and pay attention to sun protection.
Swelling and temporary numbness may occur, but most cases recover to normal within a few days.

Ultherapy Differentiation Points at Kkeut Oriental Medicine Clinic
Kkeut Oriental Medicine Clinic does not complete the procedure with just one 4.5mm main tip.
We use 3.0mm, 2.0mm, and 1.5mm tips, changing them according to the area and depth, targeting each layer of the skin step by step.
This is because delivering energy evenly from the shallow to the deep layers around the double chin enhances the completeness of the lifting.
There is a difference in results between treatments using only one type of tip and those using customized tips for each layer.

At Kkeut Oriental Medicine Clinic, double chin Ultherapy design is always performed in a seated position before the procedure.
Designing in a lying position changes the direction of gravity, leading to discrepancies between the actual sagging area and the targeted location.
If energy is applied to areas of the cheek with less fat, cheek hollowing can occur. Therefore, we ensure the patient is seated to precisely identify the sagging fat layer and loose skin areas before determining the treatment scope.

Kkeut Oriental Medicine Clinic precisely targets the SMAS layer by adjusting the tip's angle.
Since we perform the procedure while monitoring real-time ultrasound images, we verify in real-time that the energy is delivered precisely to the intended layer.
It's a precise procedure conducted with visual evidence, not a treatment relying solely on sensation.
After the procedure is completed, a lifting card is prepared and shared.
No matter which branch you visit, previous treatment history can be retrieved, allowing for seamless and error-free connected care.

Frequently Asked Questions
Q. Is Double Chin Ultherapy a procedure that directly removes fat?
A. Double chin Ultherapy does not destroy fat cells. It is a lifting procedure that heats the SMAS layer (fascia) to induce collagen contraction and regeneration, lifting the entire skin support structure. If there is a large amount of fat itself, combining it with fat-dissolving procedures can be considered.
Q. When do the effects of double chin Ultherapy appear?
A. Double chin Ultherapy shows some immediate collagen contraction effects right after the procedure. The complete lifting results are achieved within 3 to 6 months as collagen regenerates. It is a procedure where the effects become clearer over time.
Q. What is the downtime after a double chin Ultherapy procedure?
A. Since this procedure acts on the deep layers without damaging the epidermis, the downtime is relatively short. Temporary swelling or tingling may occur after the procedure but subsides within a few days. Most patients can return to their daily routine on the same day.
Q. How many sessions of double chin Ultherapy are needed?
A. Many patients experience the effects of double chin Ultherapy even with 1-2 sessions. At Kkeut Oriental Medicine Clinic, we assess your individual skin condition and degree of sagging before guiding you on the appropriate number of sessions. Since it is a procedure where collagen regeneration accumulates, repeated treatments for maintenance purposes are also effective.
Q. What is the difference between double chin Ultherapy and other double chin procedures?
A. Double chin Ultherapy directly heats the SMAS fascial layer to lift the skin structure itself. Its action layer and approach differ from procedures that focus on fat dissolution (such as InMode FX). Ultherapy is suitable when sagging is the main cause, while for cases with a large amount of fat, fat-dissolving procedures or a combination approach are considered.
