Double Chin & Jawline Definition — Treatment Options in Seoul
A double chin and a softened jawline are among the most common concerns raised by patients visiting clinics in Seoul, often linked to skin laxity, submental fat, or simply the natural aging process rather than body weight alone. For anyone researching a double chin treatment seoul clinics can offer, it helps to understand that results depend on individual anatomy, skin quality, and the degree of fat versus laxity involved. This page outlines the non-surgical options available at DERNA Clinic that are commonly considered for jawline definition and lower face contouring.
Understanding the concern
Submental fullness, sometimes called a double chin, can result from a combination of factors: genetics, skin elasticity loss, weight fluctuation, and posture-related muscle changes. As skin loses collagen and elastin over time, the jawline can appear less defined even without significant fat accumulation. This is why many patients seeking a double chin treatment seoul practitioners recommend are actually candidates for skin-tightening technologies rather than fat removal alone, or sometimes a combination approach discussed during consultation.
What it is
At DERNA Clinic, two device-based treatments are commonly discussed for jawline and lower face concerns: Thermage FLX and Ultherapy Prime. Thermage FLX is a radiofrequency treatment using the Solta Thermage FLX device, designed to stimulate collagen regeneration and improve skin elasticity, which can indirectly support a more defined jaw contour. Ultherapy Prime is an ultrasound-based lifting treatment that visualizes skin layers in real time and delivers energy to the SMAS, or fascia, layer, the same structural layer addressed in surgical facelifts. Neither treatment removes fat directly, but both aim to tighten and support the skin overlying the chin and jaw area.
Thermage FLX is available in 300, 600, and 900 shot options, along with a separate Eye Thermage FLX protocol for the periorbital area. Ultherapy Prime is offered in 300 and 600 shot options, with a 200 shot option available for the eye area.
Who it suits
- Patients with mild to moderate skin laxity around the jawline and under the chin
- Those seeking a gradual, non-surgical improvement rather than immediate dramatic change
- Patients who are not seeking fat reduction alone but rather firmer, more supported skin
- Adults with realistic expectations about the pace and degree of visible change
Who should avoid it
- Pregnant or breastfeeding individuals
- Patients with active skin infections, open wounds, or severe acne in the treatment area
- Those with certain implanted electronic devices, such as pacemakers, without prior medical clearance
- Patients expecting surgical-level tightening from a single non-surgical session
A consultation with one of the clinic's doctors is the appropriate way to determine candidacy, since skin quality, degree of laxity, and medical history all factor into suitability.
How the session goes
Sessions typically begin with a consultation and skin assessment, during which the treating doctor reviews medical history and discusses expectations. For Thermage FLX, a numbing cream or cooling gel is often applied before radiofrequency energy is delivered across the treatment area in a grid-like pattern; patients commonly describe a warming or brief heat sensation. Ultherapy Prime uses real-time ultrasound imaging so the practitioner can target the appropriate depth before delivering focused ultrasound energy; some patients report a tingling or momentary discomfort during energy delivery. Session length varies depending on the shot count selected and the area treated, and the doctor will explain the plan before starting.
Downtime and recovery
Both treatments are generally considered low-downtime procedures, meaning most patients can resume daily activities shortly afterward. Some redness, mild swelling, or a warm sensation in the treated area is common in the hours following treatment and usually subsides within a day or two. Bruising is possible but not typical. Because Thermage FLX and Ultherapy Prime work by stimulating the body's own collagen production, visible improvement tends to build gradually over weeks to months rather than appearing immediately, and the degree of change varies from person to person. Sun protection and gentle skincare are usually advised in the days following a session.

Safety
Thermage FLX and Ultherapy Prime are established, widely used device-based technologies, but as with any medical treatment, individual response and risk profile differ. Temporary side effects such as redness, swelling, or tenderness are the most commonly reported issues, while more significant complications are uncommon but should still be discussed during consultation. Patients are encouraged to disclose full medical history, including any skin conditions, prior facial procedures, or implanted devices, so the treating doctor can assess suitability appropriately. Dr. Ko Bumjun, an otolaryngologist with a focus on nose and facial contouring, and Dr. Kim Yunseok, an orthopedic surgeon and the clinic's Representative Director, are among the physicians patients may consult regarding facial contour concerns, alongside the clinic's other doctors.
Frequently asked questions
How many sessions are usually needed for a double chin treatment in Seoul?
This varies by individual, as it depends on skin laxity, age, and treatment goals; some patients opt for a single session while others discuss a follow-up session with their doctor based on how their skin responds over the following months.
Will Thermage or Ultherapy remove fat under the chin?
No, both treatments primarily target skin tightening through collagen stimulation rather than fat removal, so patients with significant submental fat should discuss additional options with their doctor during consultation.
When will I see results after treatment?
Results typically develop gradually over several weeks to a few months as collagen remodeling occurs, and the degree of visible change differs between patients.
Is there any downtime after these treatments?
Most patients experience minimal downtime, though mild redness, warmth, or swelling in the treated area is common for a day or two afterward.
Can I book a consultation in English?
Yes, some doctors at the clinic, including Dr. Ko Bumjun, are noted as English fluent, and others are noted as conversational in English; you can request an English-speaking doctor when booking your appointment.
