Double chin treatment is a set of non-surgical procedures that reduce the fullness under the jaw, known as submental fullness, to create a cleaner, sharper jawline. It targets two separate issues: a localised pocket of fat beneath the chin, and skin or muscle laxity that softens the profile. A tailored plan addresses whichever of these is driving your double chin, which is why assessment matters before choosing a method.
Importantly, this is a contouring treatment for a specific area, not a weight-loss programme. A double chin can persist even in slim, fit people because submental fat is often genetically stubborn and does not always respond to diet or exercise. Non-surgical options aim to refine the local contour and jawline definition, not to change body weight, and results are described in terms of a sharper profile rather than kilograms lost.
At Reberry Clinic, double chin care is consultation-led. Because we are based in Gangnam, Seoul, easily reached from Gangnam Station, international patients can plan sessions around their travel. Dr. Yoongon Ryu, an Aesthetic Medicine Specialist, grades your fat and skin laxity, then builds a plan combining the right modalities, with English-speaking support throughout.
Double chin plans usually combine two mechanisms. Fat-dissolving injections use a deoxycholic-acid-based solution that disrupts the membranes of fat cells in the submental pocket, so the body gradually clears them over several weeks; because the destroyed fat cells do not return, results build across a series of sessions. To address the skin and profile, energy-based tightening is layered in: radiofrequency, delivered via devices such as InMode, heats the deeper skin to stimulate collagen and firm lax tissue, while microwave-based energy such as Onda uses Coolwaves to warm the fibrous and fat layers to support contour and skin tightening. Combining fat reduction with skin tightening matters because removing fat alone can leave the area looking loose if the skin does not retract. The clinic’s doctors sequence these so the area is contoured and firmed together rather than one at the expense of the other. Because submental fat is a local deposit, the aim is sharper jawline definition in that region, not overall weight change, and the exact combination and number of sessions is confirmed after assessing your fat and skin laxity at consultation.

The clinic’s doctors grade your submental fat and skin laxity across the 2 main drivers, which sets the plan and session count.
Fat-dissolving injections disrupt fat-cell membranes in the submental pocket, and most plans use a series of 2 to 4 sessions spaced weeks apart.
RF or microwave energy heats deeper layers to stimulate collagen, usually layered in so the skin firms as fat reduces.
The body clears disrupted fat cells over roughly 4 to 8 weeks, so the contour sharpens progressively between sessions.
Your doctor reviews progress at each visit and adjusts the plan, since 1 person may need fewer sessions than another.

The clinic’s doctors grade your submental fat and skin laxity, then explain which modalities your plan needs and what drives cost, in English.
A first session usually takes about 20 to 40 minutes depending on whether injections, energy tightening, or both are used.
Because the double chin is treated over a series, cost and time are mapped across the whole plan, not a single visit.
The contour sharpens gradually over several weeks as fat clears and skin firms, with your doctor reviewing progress between visits.
Fat-dissolving results are lasting if weight stays stable, since cleared fat cells do not return; healthy habits help maintain the profile.
The right option depends on whether fat, skin laxity, or both cause your double chin, so plans are individualised rather than one-size-fits-all. Many combine fat-dissolving injections with skin tightening over a series. You can explore the approach on our fat-dissolving injection page and confirm at consultation.
No, double chin treatment is contouring of a specific area, not weight loss. It targets a localised pocket of submental fat and lax skin to sharpen the jawline. Body weight is unchanged, which is why even slim people choose it for a stubborn double chin that does not respond to diet.
Fat-dissolving injections use a deoxycholic-acid-based solution that disrupts the membranes of fat cells in the submental pocket, so the body gradually clears them over weeks. Because the destroyed cells do not return, results are lasting if weight stays stable. A series of sessions builds the final contour.
Most non-surgical double chin plans run over a series of 2 to 4 sessions spaced weeks apart, though the exact number depends on your fat volume and skin laxity. Your doctor reviews progress between visits and may need fewer or more. You can read more on our slimcut injection page.
Both can be addressed, which is why combined plans are common. Fat-dissolving injections reduce the fat pocket, while RF or microwave energy tightens the skin so the area does not look loose. Our RF skin tightening options are often layered in for a firmer, sharper jawline.
Some swelling and tenderness under the chin is common for a few days after fat-dissolving injections, as the area responds. Energy tightening usually causes only mild warmth or redness. Downtime is generally limited and non-surgical, and your doctor explains what to expect before each session so you can plan.
Most patients tolerate double chin treatment well, and numbing is used to keep injections and energy tightening comfortable. You may feel warmth, pressure, or mild stinging during the session, and some tenderness afterwards. Your doctor manages comfort throughout and explains sensations for each modality before you begin.
Visible sharpening usually builds over several weeks as the body clears disrupted fat cells and skin firms, not immediately after one session. Most patients notice progressive improvement across their series. Your doctor reviews each visit so the plan stays matched to how your submental area is responding.
Fat-dissolving results are lasting because cleared fat cells do not return, provided your weight stays stable, since significant weight gain can enlarge remaining cells. Skin-tightening effects develop over months and can be maintained with occasional sessions. Your doctor discusses longevity and any maintenance at consultation.
Cost depends on how many sessions and modalities your plan needs, such as injections or energy tightening, so there is no single fixed figure. The clinic’s doctors confirm your cost at consultation after grading your fat and skin laxity. You can start on our slimcut injection page.
Good candidates have a defined submental fat pocket or mild laxity and realistic, contour-focused goals. Very loose skin may be better assessed for other options, and RF tightening can help firmer profiles. A consultation grades your fat and skin so your doctor can confirm the plan.
Yes, double chin care is often combined with lifting or tightening for the lower face to enhance jawline definition. Your doctor sequences treatments so the skin is not over-stressed. A microwave lifting option, for example, can complement fat reduction for a smoother, firmer contour.
Non-surgical double chin treatment is widely performed and generally considered safe when a trained doctor assesses the area and controls technique and dosing. Temporary swelling, tenderness, or bruising can occur. A consultation screens for contraindications like swallowing issues or bleeding risks, so the plan is matched safely to you.
Our Gangnam (Seoul) location is convenient and easily reached from Gangnam Station, with English-speaking staff. Dr. Yoongon Ryu assesses your submental area and tailors a non-surgical plan. Many international patients schedule sessions here around their travel, and timing is arranged to fit a course of visits.
For a first session, 2 to 3 days is comfortable, allowing consultation, treatment, and a short review as any swelling settles. Because double chin plans run as a series, many international patients begin in Seoul and continue on return trips. Our English-speaking team helps coordinate timing and cost.
Flying within a day or two is generally fine after non-surgical double chin treatment, though some swelling under the chin is normal for a few days. Cabin air is drying, so stay hydrated and follow aftercare. If you had fat-dissolving injections, your doctor advises on managing swelling while you travel.
International patients can complete a double chin course across one or more visits, and the clinic offers remote check-ins in English between trips so the plan stays on track. Your treatment notes are kept on file for continuity, and you can plan your next session flexibly around future travel to Seoul.
