Non-surgical jawline contouring in Korea sharpens the lower face without cutting bone, by matching a device or an injection to whatever blurs the jaw edge: loose skin, a bulky chewing muscle or soft fat under the chin. Radiofrequency devices such as Thermage FLX, Oligio and InMode heat the dermis, focused ultrasound reaches deeper layers, and botulinum toxin slims the masseter. Device sessions usually take under an hour after numbing cream, and most visitors can fly home the same day with mild redness or swelling. Tightening builds over two to three months, while toxin slimming appears after a few weeks. Clinics charge per shot, line, area or toxin unit before VAT, and the clinic list and price table on this page let you compare both.

Who Vline Nonsurg in Gangnam suits, and who should wait
The approach suits a jaw line that has lost definition rather than one that is wide by structure: an edge between jaw and neck that is fading, small jowls beside the chin, or square corners from a strong masseter. Skin that still recoils when pinched responds to heat far more predictably than skin that hangs in a fold.
It will not narrow a broad mandible, shorten a long chin or correct asymmetry that sits in the bone; readers who want that structural change will find it on the V-line surgery pages of this site. Heavy skin excess after major weight loss and a large fat pad under the chin also respond poorly, and a frank consultation says so.
Usually a good fit
- Jaw edge fading into the neck
- Early jowls beside the chin
- Square corners from a strong masseter
- Small, soft fat pad under the chin
May be better to wait
- Pregnant or breastfeeding
- Active acne, infection or wounds on the jaw
- Metal or electronic implants near the area
- Wide jaw bone or heavy, folded skin

How it works
How a Vline Nonsurg session runs
Each tool acts on one layer, so the cause matters more than the brand. Monopolar radiofrequency, used by Thermage FLX from Solta Medical and Oligio from Wontech, warms the dermis in bulk to roughly 3 mm, and collagen contracts and then remodels. InMode pairs bipolar radiofrequency with suction that folds the skin so heat travels deeper; clinics use its Forma handpiece for dermal tightening and the FX handpiece on the contour. Ultherapy and Shurink Universe use focused ultrasound at 1.5, 3.0 and 4.5 mm, the last reaching the SMAS. Onda (microwave) and Soprano Titanium (diode laser) are common add-ons.
Research on radiofrequency for the lower face is moderate and consistent. In a 2007 study in Lasers in Surgery and Medicine, Bogle and colleagues treated 66 adults with a multiple-pass, low-fluence monopolar protocol; at six months 92% showed measurable improvement, though device-measured stiffness gains faded with time. A 2019 split-face trial in Dermatologic Surgery by Alhaddad and colleagues found monopolar radiofrequency and microfocused ultrasound improved laxity to a similar degree. Chottawornsak and colleagues reported in the Journal of Cosmetic Dermatology in 2026 that one session with a Korean bimodal radiofrequency device improved lower-face laxity ratings for six months.
Injections cover the other two causes. Botulinum toxin in the masseter relaxes the muscle, which thins over the following weeks; clinics in Korea stock imported products such as Botox and Xeomin next to Korean brands such as Nabota and Coretox, and charge per unit or per area. For fat, deoxycholic acid is the one injectable backed by controlled clinical trials, and those trials studied fat under the chin, not the jaw line or cheeks. The multi-ingredient contour cocktails many clinics mix in-house have no published controlled trials, so their effect is unproven.
Cause check
The doctor feels the jaw while you clench and relax, pinches skin along the border and under the chin, and decides which layer blurs the line. A combined plan should state order, shot count and toxin dose.
Numbing
Numbing cream sits on the jaw and neck for roughly half an hour before ultrasound or monopolar radiofrequency. Masseter toxin needs little or none, and Onda relies on its own cooling.
Treatment
Passes along the jaw border, jowl and under-chin zones take about 30 to 60 minutes depending on the shot or line count. Toxin takes a few minutes per side with a fine needle.
Cooling and checks
Cool packs and a calming mask follow. Redness usually settles within hours, and makeup is normally fine the next day.

What the days after look like
Warmth, pinkness and a tight feeling along the jaw; toxin points may be tender when you chew.
Mild swelling can make the jaw look fuller before it looks sharper, and small bruises may show.
Masseter toxin begins to soften the corners of the jaw, and hard food may tire the muscle for a while.
Collagen remodeling after heat devices peaks, and the doctor can judge whether a further step is worth it.
Safety
Vline Nonsurg risks and limits
- Short-lived redness, swelling and tenderness along the jaw.
- Bruising and tired chewing muscles after masseter toxin.
- Uncommon burns, blisters or small dents from heat devices.
- Toxin drifting to nearby muscles can alter the smile until it wears off.
- Rare temporary numbness or weakness from nerve irritation.
- No device or injection narrows bone or removes a large skin excess.

FAQ
Questions about Vline Nonsurg in Gangnam
Which device suits a non-surgical jawline lift for loose skin?
Radiofrequency and focused ultrasound are the two device families used when loose skin is what blurs the jaw edge. Radiofrequency such as Thermage FLX or Oligio heats the dermis evenly, while ultrasound such as Ultherapy reaches the SMAS, which holds early jowls. A 2019 split-face trial by Alhaddad and colleagues in Dermatologic Surgery found both improved laxity similarly, so sensation and zone often decide.
How does an InMode jawline session differ from Thermage?
InMode uses bipolar radiofrequency with suction that folds the skin, while Thermage FLX sends monopolar radiofrequency through a flat tip into the dermis. The suction concentrates heat in the fold of skin and fat along the jaw, so clinics often use it for contour work, whereas Thermage targets broad tightening. Ask which handpiece, Forma or FX, will be used and how many passes each zone gets.
Can masseter toxin and a heat device be done on the same visit?
Many clinics combine them on one visit, usually with the device first and the toxin afterward. Heat and pressure right after an injection could move the toxin, so the device step goes first; some doctors split the two by a few days instead. Either way, the toxin brand, units per side and device shot count should be listed separately on the plan.
Do contour injections really melt fat along the jaw?
Deoxycholic acid is the one injectable with controlled clinical trial evidence, and that evidence covers fat under the chin, not the jaw line or cheeks. It destroys fat cells and causes marked swelling for several days, often over more than one session. House-mixed contour cocktails, sometimes sold under catchy names, have no published controlled trials, so their effect is unproven. Ask for the product name and its approval status before any injection is booked.
How long does jawline lifting with radiofrequency last?
Results from radiofrequency tightening fade gradually, so a repeat session is often planned later. In a 2007 study in Lasers in Surgery and Medicine, Bogle and colleagues saw clinical improvement at six months, while device-measured skin stiffness gains declined over time. Ageing continues after treatment, so the jaw edge slowly softens again. Results vary from person to person, depending on skin quality, weight changes and sun exposure.
Will these treatments make my face look thinner or hollow?
They can, if fat-targeting energy or injections are used on a face that is already lean. Microwave devices, InMode contour passes and deoxycholic acid all reduce fat, which helps a full jaw but can deepen hollows in the cheeks. A careful plan treats the jaw border and under-chin area and leaves supporting volume alone, so mention any past weight loss at the consultation.
Can I fly home the day after jaw treatment in Korea?
Yes, flying home the same day or the next morning is generally possible after device sessions and toxin. Expect mild swelling, redness or a few bruises that fade within days. Skip saunas, hard facial massage and heavy alcohol for the first few days. If fat-reducing injections are planned, allow extra days, since swelling under the chin can be marked.
How can I check that genuine tips and toxin are used?
Ask to see the sealed tip, cartridge or toxin vial before treatment and check the brand printed on it. Radiofrequency tips often carry a shot counter, ultrasound cartridges show remaining lines on the device screen, and toxin vials show a batch number and expiry date. A clinic that opens the package in front of you is easier to trust.
How do Korean clinics charge for jaw treatments?
Device treatments are usually charged per shot, line or area, and toxin per unit or per side. Listed prices are before VAT, and 10% VAT is added at payment. Packages that combine a device with toxin may look simpler, but the shot count and toxin brand inside them can differ.
