Body Ultherapy uses micro-focused ultrasound to reach 3 depths (typically 1.5, 3.0 and 4.5mm), heating tissue to stimulate collagen and tighten loose skin on the body.
Body Ultherapy is micro-focused ultrasound (MFU) applied to the body, delivering precise heat to the deeper layers of areas like the abdomen, upper arms and knees to trigger collagen renewal and gradual skin tightening. At our Gangnam (Seoul) location, Dr. Yoongon Ryu tailors it as a non-surgical, minimal-downtime option, with results building over 2 to 3 months.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.

Body Ultherapy is the application of micro-focused ultrasound (MFU) technology to areas of the body rather than the face. It uses the same principle as facial Ultherapy: focused ultrasound energy is delivered at set depths beneath the skin, heating small points of tissue to a temperature that stimulates the body to build new collagen. Over the following weeks and months, that renewed collagen tightens and firms lax skin non-surgically.
On the body, the target areas are typically the abdomen, upper arms, knees and other zones where skin has become loose, for example after weight change or with age. Because ultrasound reaches deep layers precisely while leaving the surface intact, it can address laxity that topical creams and lighter devices cannot, without incisions or a long recovery. It is a firming and skin-tightening treatment, not a fat-removal or weight-loss procedure.
At Reberry Clinic, Body Ultherapy is offered as part of a consultation-led body-firming menu. At our Gangnam (Seoul) location, Dr. Yoongon Ryu assesses the area, sets realistic expectations, and plans treatment in English. International patients are supported across our three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), so treatment can be arranged around your travel schedule.
Body Ultherapy relies on micro-focused ultrasound, the same MFU energy used on the face but with body-appropriate transducers. The device focuses ultrasound waves to precise depths beneath the skin, commonly around 1.5, 3.0 and 4.5mm, where it creates tiny thermal coagulation points that reach roughly 60 to 70 degrees Celsius. This controlled heat denatures a small amount of existing collagen and triggers a wound-healing response, prompting fibroblasts to lay down new collagen and elastin over the following 2 to 3 months. Crucially, because the energy is focused below the surface, the epidermis is spared, which is why downtime stays minimal. Some body devices with visualization let the doctor see the tissue layers being targeted, improving precision and safety over thicker body skin. Since new collagen forms gradually, the tightening effect is progressive, and larger or looser body areas often benefit from a planned approach rather than expecting an immediate change.

The doctor evaluates the body area and skin laxity, marks the zone, and selects transducers for the right depths, typically 1.5, 3.0 and 4.5mm.
Micro-focused ultrasound is delivered in a grid across the area, creating thousands of tiny heat points at the 3 chosen depths beneath the surface.
Each point reaches roughly 60 to 70 degrees Celsius, hot enough to denature collagen and start a renewal response while the surface stays intact.
Over the next 2 to 3 months, fibroblasts build fresh collagen and elastin, so tightening develops gradually rather than appearing on the same day.
Larger or looser areas may benefit from a staged plan, and your doctor reviews progress before deciding whether a further session adds value.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.
At our Gangnam (Seoul) location, Dr. Yoongon Ryu assesses the area and skin laxity, sets realistic expectations, and confirms suitability, in English.
Depending on the area, a session usually takes about 30 to 60 minutes, and numbing or comfort settings are used to keep it tolerable.
Many body areas are treated in a single session, though larger or looser zones may be planned as a staged approach across visits.
Tightening develops gradually over 2 to 3 months as new collagen forms, rather than appearing immediately after treatment.
Results are supported by stable weight, hydration and sun protection, and occasional maintenance sessions help sustain firmness over time.
Body Ultherapy is micro-focused ultrasound (MFU) applied to the body, delivering focused heat to deep layers to stimulate collagen and tighten loose skin. It commonly treats the abdomen, upper arms and knees non-surgically. You can read more about the technology on our Ultherapy Prime page.
Body Ultherapy is offered at our Gangnam (Seoul) location, where Dr. Yoongon Ryu plans and performs it in English. Gangnam is about 2 minutes from Gangnam Station exit 10, and international patients are supported across our three Seoul-area locations. A consultation confirms whether the area suits treatment.
Common areas are the abdomen, upper arms, knees, and other zones where skin has loosened, for example after weight change or with age. Suitability depends on the type and degree of laxity, which your doctor assesses at consultation. Body Ultherapy tightens skin, so it works best on true skin laxity rather than fat.
No, Body Ultherapy is a skin-tightening treatment, not a fat-removal or weight-loss procedure. It stimulates collagen to firm lax skin rather than reducing fat volume. If your concern is localised fat, your doctor can discuss other options at consultation, since choosing the right approach depends on your specific goal.
Body Ultherapy delivers brief deep pulses that some describe as a warm, prickling sensation, and comfort is managed with numbing and adjustable settings. Body skin is often thicker, so it is generally well tolerated. Your doctor tailors the energy to keep the session comfortable while still effective for your area.
Downtime is minimal, so most people return to daily activities the same day. Temporary redness, mild swelling or tenderness in the treated area can occur and usually settles within days. Because the surface is not broken, there are no wounds to heal, which makes it convenient for busy or travelling patients.
Tightening develops gradually over about 2 to 3 months as new collagen forms, rather than appearing immediately. Some firmness may be noticeable earlier, but the fuller effect builds with time. Your doctor reviews the area at follow-up to assess progress, similar to facial Ultherapy timelines.
Many body areas are treated in a single session, but larger or looser zones may benefit from a staged plan across visits. The number depends on the area, skin thickness and your goals, which are set at consultation. Your doctor reviews your response before recommending any further treatment.
Results can last a year or more, but skin continues to age and weight changes can affect firmness, so it is maintained rather than fixed permanently. Stable weight, hydration and sun protection help results last. Some patients schedule occasional maintenance to sustain the tightening effect over time.
Body Ultherapy uses focused ultrasound to reach deep layers precisely, while radiofrequency spreads gentler heat more broadly across the dermis. Ultrasound suits focused deep tightening, and RF suits even firming over larger surfaces. You can explore radiofrequency options on our RF body tightening page.
Yes, it is often combined with radiofrequency or thread-based options in a staged plan for a fuller firming result. Your doctor sequences treatments so the tissue is not over-stressed. For a mechanical lift of sagging skin, a thread lift may be added, depending on your anatomy and goals.
Adults with mild to moderate loose skin who are at a stable weight and want non-surgical firming are typically good candidates. It is less suited to severe sagging that may need surgery. A consultation assesses your laxity and confirms whether Body Ultherapy or another body rejuvenation option fits best.
Side effects are usually limited to temporary redness, mild swelling, tenderness or small areas of numbness that resolve within days to a few weeks. Serious effects are uncommon when a trained doctor sets appropriate depths and energy. A consultation reviews your history so the plan is matched safely to your body area.
Aftercare is simple: keep the area clean, stay hydrated, protect it from strong sun, and avoid intense heat for a day or two. Gentle movement is usually fine. Because results depend on collagen forming over weeks, a healthy routine and stable weight support the outcome and help maintain firmness.
Cost depends on the size of the area treated and the number of ultrasound shots or sessions your plan needs, so there is no single fixed price. Reberry Clinic is consultation-led, and the clinic’s doctors confirm a transparent, individualised cost after assessing the area at your Gangnam consultation in English.
For a single body session, 1 to 2 days is usually comfortable, since downtime is minimal and you can travel soon afterwards. If a staged plan is advised, many international patients begin in Seoul and arrange return visits. Our English-speaking team helps coordinate timing around your travel.
Yes, flying within a day or so is generally fine, as Body Ultherapy is non-surgical with minimal downtime. Any tenderness or mild swelling usually settles quickly, and staying hydrated helps. If you have questions while travelling, the clinic offers remote check-ins in English so your recovery stays on track.
International patients can complete Body Ultherapy in one visit and review results remotely, with the clinic offering check-ins in English between trips so progress is tracked. You can support results with a healthy routine and continue related skin care at home, and your treatment notes are kept on file for continuity.
