Double Chin & Jawline Definition — Treatment Options in Seoul
A double chin, or fullness beneath the jawline, is one of the most common concerns raised by patients visiting clinics in Seoul. It can result from genetics, skin laxity, weight fluctuation, or simply the natural loss of collagen that comes with aging. For patients researching a double chin treatment seoul option, it helps to understand that not every case is the same: some patients have excess fat, others have loose skin, and many have a combination of both. This page explains the concern in general terms and outlines the non-surgical lifting and skin-tightening options available at DERNA Clinic that may help improve jawline definition.
Understanding the concern
Submental fullness and a poorly defined jawline are usually caused by a mix of factors: fat deposits under the chin, reduced skin elasticity, and sometimes muscle laxity in the neck. Because the causes vary from person to person, results from any treatment will also vary. A consultation is the only reliable way to determine which combination of factors applies to an individual patient and which approach may be appropriate.
What these treatments are
DERNA Clinic offers energy-based skin tightening treatments that are commonly used to support jawline definition by improving skin firmness and stimulating the body's own collagen production. These are not surgical procedures and do not remove fat directly; instead, they work on the skin and supportive tissue layers.
- Thermage FLX uses radiofrequency energy delivered through the Solta Thermage FLX device to heat the deeper skin layers, encouraging collagen renewal over time. It is offered in 300, 600, and 900 shot options.
- Eye Thermage FLX applies the same radiofrequency technology specifically to the delicate eye area, available in 225 or 450 shot options. While focused on the eyes rather than the jawline, some patients combine it with facial Thermage for an overall refresh.
- Ultherapy Prime is an ultrasound-based lifting treatment that visualizes skin layers in real time and targets the SMAS layer, the fascia layer that supports facial structure. It is available in 300 and 600 shot options, with a 200-shot eye option.
These treatments are generally described as supporting a firmer, more lifted appearance along the jawline and neck area, rather than reducing fat volume.
Who it suits
Patients who are considering a double chin treatment seoul clinics offer are often those with mild to moderate skin laxity under the chin and along the jawline, rather than significant fat accumulation. People in their late 20s through 50s who notice early sagging, loss of definition, or a softer jawline contour are typical candidates for Thermage FLX or Ultherapy Prime. These treatments may also suit patients who want to maintain results after weight loss, when skin has not fully retracted on its own.
Who should avoid it
These treatments are not suitable for everyone. Patients who are pregnant or breastfeeding, those with active skin infections or severe acne in the treatment area, and individuals with certain implanted electronic devices such as pacemakers should avoid radiofrequency or ultrasound-based treatments. Patients with unrealistic expectations about fat removal should also understand that these are skin-tightening treatments, not fat-reduction procedures. A full medical history should be reviewed during consultation before any treatment plan is confirmed.
How the session goes
During a Thermage FLX or Ultherapy Prime session, the treatment area is cleaned and a numbing cream or cooling method may be applied depending on individual sensitivity. The device is then passed over the skin in a grid pattern, delivering controlled energy pulses. Patients commonly describe a warming or tingling sensation with Thermage, and a brief prickling sensation with Ultherapy, particularly at the higher energy settings. Sessions typically take between 30 minutes and just over an hour depending on the number of shots selected and the size of the area treated. Because these are non-surgical procedures, most patients remain awake and alert throughout, and can discuss comfort levels with the treating doctor during the session.
Downtime and recovery
One of the appeals of these treatments is the minimal downtime involved. Most patients experience mild redness or warmth in the treated area immediately afterward, which usually settles within a few hours. Some swelling can occur, particularly with Ultherapy, and typically resolves within a day or two. There is generally no requirement to take extended time off work, though patients are advised to avoid excessive sun exposure and very hot showers for a short period after treatment. Visible improvement is gradual rather than immediate, since the treatments work by stimulating collagen production over the following weeks to months. Results and timelines vary between individuals, and some patients may benefit from repeat sessions to maintain or build on initial improvement.

Safety
Radiofrequency and ultrasound skin-tightening treatments are widely used in aesthetic medicine, but like any procedure they carry some risk, including temporary redness, swelling, or in rare cases, uneven results or discomfort during treatment. Individual response depends on skin type, age, and the underlying cause of jawline fullness. No treatment can guarantee a specific outcome, and results are not permanent; skin continues to age naturally afterward, and periodic maintenance sessions may be considered. Dr. Ko Bumjun, an otolaryngologist with a focus on nose and face contour, is among the doctors at DERNA Clinic who may be involved in consultations related to facial contouring concerns, alongside the clinic's broader medical team.
Frequently asked questions
Can Thermage or Ultherapy remove fat from under the chin?
No, these are skin-tightening treatments that work on collagen and supportive tissue rather than removing fat directly, so patients with significant fat volume may see limited change in that specific area.
How many sessions are typically needed?
Many patients see improvement after a single session, though some choose repeat treatments over time to maintain results, and the appropriate plan depends on individual skin condition as assessed during consultation.
Is the procedure painful?
Most patients report a warming or tingling sensation with Thermage and a brief prickling feeling with Ultherapy; discomfort levels vary by person and can often be managed with numbing cream or adjusted energy settings.
When will I notice results?
Because these treatments stimulate collagen production gradually, visible changes typically develop over several weeks to a few months rather than immediately after the session.
Do I need to take time off after treatment?
Downtime is generally minimal, with most patients returning to normal activities the same day, though mild redness or swelling may be present for a short period afterward.
