Double chin Ultherapy, does it really work? Starting with distinguishing between the fat-type and sagging-type

Double chin Ultherapy is not a treatment that melts and removes fat, but a lifting treatment that tightens the fascia layer (SMAS) under the skin with heat to lift the sagging jawline. Therefore, you need to know this one thing first: whether your double chin is caused by 'too much fat' or by 'sagging skin and loss of elasticity.' Depending on the cause, Ultherapy may be the best answer, or it may not be as effective as expected.

Ultherapy is a HIFU device from Merz in the US, and it is a lifting device that received US FDA approval in 2012 for the improvement of jaw and neck wrinkles. The effect does not appear immediately after the procedure, but gradually starts from 2 to 3 months later when collagen fills up again, and usually lasts from 6 months to as long as 2 years. In this article, we will take a step-by-step look from the perspective of Onlif Clinic, covering everything from identifying the cause to the timing of effects, costs, side effects, and verifying genuine products.

🔍 Double Chin Ultherapy is Not a Fat Removal Treatment

This is where many people misunderstand. Ultherapy is not a treatment that removes fat. The core objective is to tightly contract the sagging skin and SMAS fascia layer, and in the process, stimulate collagen regeneration to restore elasticity.

The operating principle is as follows. HIFU (High-Intensity Focused Ultrasound) focuses ultrasound energy at a single specific depth point beneath the skin. At that point, a Thermal Coagulation Point of 60–70°C is created. This method delivers micro-thermal stimulation only to the deep layers while leaving the skin surface untouched. This thermal stimulation immediately contracts the tissue, and subsequently, new collagen is created as a healing response of the body trying to recover the wound. This is neocollagenesis, or collagen regeneration.

The most important target here is the **SMAS (Superficial Muscular Aponeurotic System)**. It is a thin fascia layer above the muscles that support the face, which is the very layer targeted by lifting threads or facelift surgery. Ultherapy delivers heat to this layer without using a scalpel, producing a lifting effect.

📌 Key Summary: Ultherapy is a non-invasive lifting treatment that stimulates collagen regeneration by tightening the skin and SMAS fascia layer, rather than removing fat.

🧭 Is My Double Chin the Fat Type or the Sagging Type?

The cause eventually determines the effectiveness of Ultherapy. A double chin usually appears as a mixture of five causes.

There is also a simple self-check method. If you pinch the skin under your chin with your hand and it feels thick, it is closer to the fat type; if the skin is thin but sags when you look down and tightens up when you look up, it is closer to the sagging/loss of elasticity type.

Ultherapy shines brightest for the sagging and loss of elasticity types. Conversely, if there is a lot of fat, Ultherapy alone may not be enough. In this case, we consider fat-dissolving injections (deoxycholic acid) or other approaches together. When the cause is bone structure, such as a receded chin, we must honestly acknowledge the limitations of skin treatments.

For reference, there are also cases where the salivary glands protrude, looking like a double chin, or where the platysma bands are distinct. Since these cases are difficult to resolve with Ultherapy's lifting alone, accurate differentiation prior to treatment is paramount.

📌 Key Summary: Ultherapy is suitable for the sagging/loss of elasticity type, but because the effects are limited for the fat, skeletal, and platysma types, identifying the cause comes first.

⏳ When Will the Effect Start and How Long Will It Last?

The effect of Ultherapy requires patience. Although there is some minor contraction immediately after the procedure, the real change begins to appear in earnest from 2 to 3 months later, when new collagen fills in. The peak effect is roughly around the 3 to 6-month mark.

The maintenance period varies greatly from person to person. It is commonly reported to be 6 months to 1 year, and up to 2 years if well maintained. However, there is one thing to clarify. Ultherapy is not a treatment that reverses aging, but a concept of slowing it down. As time flows, the skin will naturally age again, and this slows down that speed.

Weight is also a variable. If you gain significant weight after the treatment, the lifting effect may be masked by the newly accumulated fat. If you want to see long-lasting effects, weight management must go hand-in-hand.

📌 Key Summary: The effect begins in earnest after 2 to 3 months, peaks at 3 to 6 months, usually lasts 6 months to 2 years, and is a concept of slowing down aging rather than reversing it.

🎯 Cartridge Depth and Shot Count, Which Is More Important?

The precision of Ultherapy treatment comes from the choice of cartridge (transducer). It is divided into three types depending on the targeting depth.

• 1.5mm: Shallow dermis layer, fine wrinkles/skin texture

• 3.0mm: Deep dermis layer

• 4.5mm: SMAS fascia layer — the key depth for lifting

In double chin lifting, the one doing the real work is the 4.5mm cartridge. This is because the SMAS must be precisely targeted to achieve a proper lift. Therefore, we design a combination of depths according to the area and skin thickness.

The unique strength of Ultherapy comes from here. With its real-time ultrasound imaging feature called DeepSee™, we can deliver energy to the precise layer while visually checking the subcutaneous structures during the procedure. There is a clear difference in safety compared to devices that shoot blindly based on intuition without imaging.

Let's also address the misunderstanding about the number of shots (lines). For a double chin standalone treatment, roughly 100 to 400 lines are used, and if including the entire face and neck, more than 600 to 1,000 lines are used. However, having more shots does not guarantee better results. The results depend on at what depth, at what angle, and where the energy is delivered in accordance with an individual's anatomical structure. It is about design and accuracy rather than numbers.

📌 Key Summary: The core depth for double chin lifting is 4.5mm targeting the SMAS, and the depth, design, and accuracy determine the results rather than the shot count.

💰 How Much Does It Cost?

The cost varies depending on the clinic, equipment, and the scope of the treatment. The rough market price is as follows.

One thing to be careful here: you should be suspicious of excessively cheap treatments. Genuine cartridges have a fixed cost as consumables, so if the price is unbelievably cheap, we cannot rule out the possibility of recycled tips or counterfeit products. Rather than choosing based on price alone, checking what they use comes first.

📌 Key Summary: For a double chin, Ultherapy is priced in the range of 900,000 to 1,500,000 KRW based on 300 shots, and you must check the authenticity of the cartridge for excessively cheap procedures.

✅ How Do I Verify Genuine Cartridges?

Verifying genuine cartridges in Ultherapy is not optional, but essential. Recycled or counterfeit cartridges have low energy accuracy, which may lead to minimal effects or, in severe cases, side effects such as burns.

The verification method is surprisingly simple. Open the 'Ultherapy from the Start' mobile app and scan the QR code on the cartridge to see if it is genuine. Do not hesitate to request this process before the procedure. A proper clinic will gladly show you.

📌 Key Summary: Since recycled or counterfeit tips carry risks of reduced effectiveness and burns, verify the genuine product by scanning the QR code with the 'Ultherapy from the Start' app.

⚖️ How Does It Compare to Other Treatments?

Ultherapy is not the only solution for a double chin. There is a more suitable approach depending on the cause.

InMode is more suitable for the fat type because it combines high frequency with suction, and Shurink belongs to the same HIFU line as Ultherapy. Thread lifting physically pulls up sagging tissue with threads, which is considered when immediate changes are desired.

The important point is that these treatments do not compete but create synergy through combinations. For example, if both fat and sagging are present, we first clean up the fat and then tighten the elasticity with Ultherapy or thread lifting. If neck bands are prominent, we also use Botox together. This is why Onlif Clinic focuses on non-surgical lifting such as All-Tight Lifting and Thread Lifting. Combining them based on the cause without using a scalpel.

For reference, if the skeletal structure is the cause, such as a receded chin, there is an approach to complement the jawline with fillers. However, we honestly tell you that methods of changing the bone structure itself are outside the scope of skin treatments.

📌 Key Summary: The suitable treatment varies depending on whether it is the fat, sagging, or skeletal type, and combinations tailored to the cause produce more natural results than a single treatment.

🩹 What About Pain, Side Effects, and Recovery?

Ultherapy has almost no downtime, allowing you to return to daily activities the day after the procedure. However, swelling, redness, tenderness, and rarely bruising may last for a few days.

Pain varies greatly among individuals. In particular, the jawline area near bones or nerves can feel tingly or throbbing, so we manage the pain with anesthetic cream, etc.

Among the side effects, cheek denting (fat atrophy) is something to be aware of. If targeted with excessive energy or at an inappropriate depth, fat in the cheekbones and cheeks can atrophy, making them look hollow. Although not common, this is why the practitioner's experience and judgment determine the results. After all, the energy setting and depth design depend on human hands.

Avoiding heat-inducing activities such as saunas, Jjimjilbangs, intense exercise, and drinking for a week after the procedure, and focusing on moisturizing and sun protection, will help maintain the effects. Consuming sufficient protein for collagen production also provides a minor benefit.

📌 Key Summary: There is almost no downtime, but swelling and pain can last for a few days, and side effects like cheek denting, though rare, depend on the practitioner's energy design capability.

❓ Frequently Asked Questions (FAQ)

Does double chin Ultherapy remove fat or pull skin?

It is a lifting treatment that pulls the skin. It does not directly remove fat, but tightens the SMAS fascia layer and stimulates collagen regeneration. If you have a double chin with lots of fat, it is better to consider a separate fat treatment together.

How can I tell if my double chin is the fat type or the sagging type?

If the skin under your chin feels thick when pinched, it is closer to the fat type. If the skin is thin but sags when you look down and tightens up when you look up, it is closer to the sagging/elasticity type. Accurate differentiation requires diagnosis through consultation.

When will the effect show, and when is the maximum effect?

Due to the nature of collagen regeneration, the effect begins in earnest 2 to 3 months after the procedure, and the peak effect is around 3 to 6 months. It is correct to understand that it improves gradually rather than expecting a dramatic change immediately after the procedure.

How much is the cost and how many shots are needed?

It is about 300,000 to 500,000 KRW per 100 shots, and about 900,000 to 1,500,000 KRW for intensive double chin treatment (around 300 shots). However, depth and design are more important than shot count, so having more shots is not unconditionally better.

Is the treatment very painful? How is anesthesia done?

Pain varies greatly depending on the individual, and in particular, areas near bones or nerves, such as the jawline, can feel tingly. We usually proceed after managing pain with anesthetic cream, etc.

What is the difference between Ultherapy and Shurink?

Both are HIFU-class lifting devices. Ultherapy is characterized by its ability to deliver energy while verifying skin layers with DeepSee™ real-time ultrasound imaging. Which one is more suitable depends on skin condition and goals.

Which treatment is better for a double chin with a lot of fat?

For the fat type, Ultherapy alone has limitations, so fat-dissolving injections are considered together. If fat and sagging are mixed, a combination of clearing the fat first and then adding lifting is common.

Can I check if it is a genuine cartridge?

You can verify whether it is genuine by scanning the cartridge's QR code with the 'Ultherapy from the Start' mobile app. We recommend checking by requesting this before the procedure.

Can I go to work the day after the procedure?

With almost no downtime, most people can go about their daily lives the next day. However, keep in mind that swelling, redness, and tenderness may remain for a few days.

Does the effect disappear if I gain weight?

If you gain significant weight, the lifting effect may be masked by the newly added fat. It does not completely disappear, but to maintain the effect for a long time, it is better to manage your weight together.

I look like I have no chin because of a receded chin. Can Ultherapy help?

If the cause is skeletal, such as a receded chin, Ultherapy alone has limitations. In this case, an approach to complement the jawline with fillers can be considered, and identifying the cause is primary.

Good Things to Check Before Choosing a Clinic for Double Chin Ultherapy

Even for the same treatment, the results and recovery process vary depending on where, who, and how it is performed. Asking the following questions directly during consultation will help your decision.

• Do they perform this treatment frequently? — The main treatments handled by each clinic vary. Check if it is a place that regularly performs double chin Ultherapy.

• Can I verify the products and equipment used? — Ask during the consultation if you can verify the product name and whether it is genuine (whether it is an import-approved product, whether there is an unsealing verification process).

• Do they explain the breakdown of the cost? — Instead of just hearing the total amount, you should hear explanations about what product is used, how much, and on which areas to make an informed judgment.

• Do they design by looking at the entire face? — Even for the same treatment, the application location and amount vary depending on face shape, skin condition, and bilateral asymmetry.

• Do they explain adverse reactions and the recovery process first? — A place that informs you of possible adverse reactions and how to handle them is better for making a decision than a consultation that only talks about expected changes.

• Is there a follow-up pathway after the treatment? — Check if the timing of progress checks, how to contact them when there is an anomaly, and criteria for follow-up visits are established.

This Is How Onlif Clinic Performs Double Chin Ultherapy
