Body Ultherapy is a non-surgical skin-tightening treatment that applies micro-focused ultrasound (MFU-V) to lax skin on the body rather than the face. Using the Ultherapy Prime platform, it directs focused ultrasound energy beneath the surface to areas that commonly loosen with age or weight change, such as the abdomen, upper arms, and knees. Because it works below the skin without cutting, there is no incision and no removal of tissue.
The key difference from face Ultherapy is the target area and depth strategy. Body skin is thicker and behaves differently, so the clinic’s doctors adjust the treatment lines, density, and depths to suit each region. Ultherapy Prime carries DEEPSEE visualization, which lets the practitioner see the tissue layers before delivering energy, so treatment is placed in the right plane rather than blindly.
Body Ultherapy is best understood as a firming and tightening treatment, not a fat-loss or weight-loss procedure. It improves mild to moderate skin laxity and crepey texture; it does not replace surgery for significant sagging or excess skin. At our Incheon Airport (Yeongjongdo) location, international patients receive an English-language assessment so expectations are set clearly before starting.
Ultherapy Prime is a micro-focused ultrasound (MFU-V) device. It concentrates ultrasound energy into tiny focal points that reach set depths of 1.5, 3.0, and 4.5 mm, creating precise thermal coagulation points in the deeper skin and the fibromuscular layer. This controlled micro-injury triggers the body’s natural wound-healing response, which lays down new collagen and remodels existing collagen and elastin over the following months. On the body, the 4.5 mm depth reaches the supporting fibrous layer, while shallower passes address the dermis for firmness and texture. The Prime generation adds real-time DEEPSEE imaging, so the practitioner can visualize the tissue and place energy accurately for each body region rather than working blind. Because the ultrasound bypasses the surface, the outer skin stays intact, which is why downtime is limited. This is a distinct mechanism from radiofrequency devices such as Thermage FLX, which heat tissue with monopolar RF instead of focused ultrasound.

The clinic’s doctors examine the target zone and grade laxity, then map treatment lines across the 1 or more body areas to be treated.
DEEPSEE imaging shows the tissue layers so energy is placed at the correct 1 of 3 depths for that region, not blindly.
The device creates focal heating points at 1.5, 3.0, and 4.5 mm, forming precise thermal coagulation zones below the surface.
These controlled points start a healing response that builds new collagen over roughly 2 to 6 months, gradually firming the skin.
Results are reviewed around 3 months later, and many patients repeat treatment about once every 12 to 18 months to maintain firmness.
See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.


The clinic’s doctors assess your target area, grade laxity, and confirm whether body Ultherapy fits your skin, in English at our Incheon Airport location.
After marking the area, a session commonly takes about 30 to 60 minutes depending on how many body zones are treated.
Treatment is usually completed in a single visit per cycle, with imaging-guided passes across the mapped lines.
Firming builds gradually over roughly 2 to 6 months as new collagen forms, with a review commonly around the 3-month mark.
Results often last about 12 to 18 months; gentle care and sun protection help, and many patients repeat treatment periodically.



Body Ultherapy applies the same Ultherapy Prime micro-focused ultrasound used on the face to lax skin on the body, such as the abdomen, arms, and knees. Because body skin is thicker, the depths, density, and treatment lines are adjusted. You can compare it with our Ultherapy Prime page.
Common body areas include the abdomen, upper arms, and knees, where skin often loosens with age or weight change. The clinic’s doctors confirm suitability by grading laxity in each zone. Body Ultherapy targets skin firmness in these regions rather than removing fat or excess tissue.
No, body Ultherapy is a skin-tightening treatment, not a fat-loss or weight-loss procedure. It firms mild to moderate laxity by stimulating collagen at set depths. For contouring concerns, the clinic’s doctors may discuss other approaches on our body rejuvenation page after assessment.
Ultherapy Prime focuses ultrasound into tiny points at 1.5, 3.0, and 4.5 mm, creating controlled thermal coagulation zones below the surface. This triggers your body’s collagen-building response over the following months. DEEPSEE imaging lets the practitioner see the tissue layers first, so energy is placed accurately on thicker body skin.
Most patients feel brief warmth or a deep prickling sensation as each pulse is delivered, which settles quickly between passes. Comfort is managed by adjusting settings and pacing. Sensitivity varies by area and individual, and the clinic’s doctors explain what to expect for each body zone before starting.
Downtime is usually limited because the ultrasound bypasses the skin surface. Some patients notice mild swelling, tenderness, or temporary redness in the treated area for a short time. Most people return to normal daily activity soon after, though the clinic’s doctors give tailored aftercare based on the areas treated.
Firming builds gradually over roughly 2 to 6 months as new collagen forms, not immediately after the session. Some early tightening may be noticeable sooner, but the fuller effect appears over time. A review around the 3-month mark helps track progress and plan any maintenance.
Results often last around 12 to 18 months, though this varies with age, skin quality, and lifestyle. Because natural aging continues, the effect is not a one-time fix, and many patients repeat treatment periodically to maintain firmness. The clinic’s doctors suggest a realistic maintenance interval at consultation.
Many body areas respond to a single session per cycle, with results developing over the following months. Depending on laxity and the area, the clinic’s doctors may suggest more than one session or periodic maintenance. Your plan is confirmed after they grade the target zone during assessment.
Yes, it is often combined with treatments that address different concerns, since Ultherapy targets skin firmness rather than surface tone or fat. For example, it may be paired with options shown on our body rejuvenation page. The clinic’s doctors sequence any combination to avoid over-treating the skin.
Common effects are temporary and mild, including redness, swelling, tenderness, or slight bruising in the treated area. Less common effects can include temporary numbness or small welts along treatment lines. The clinic’s doctors screen your history first and explain aftercare, which you can review alongside our Ultherapy Prime page.
Good candidates are adults with mild to moderate skin laxity and crepey texture on areas like the abdomen, arms, or knees. If sagging is significant, surgery may be more suitable, which the clinic’s doctors will explain honestly. A consultation grades your skin so the recommendation fits your realistic goals.
Body Ultherapy uses focused ultrasound to reach deeper support layers with imaging, while Thermage FLX uses monopolar radiofrequency to heat a broad area. Each suits different needs. You can read more about RF-based tightening on our Thermage FLX page and decide with your doctor.
Aftercare is simple: keep the area clean, avoid intense heat or vigorous massage for a short period, and use sun protection on exposed zones. Any mild swelling or tenderness usually settles within days. A gentle skin care routine supports the treated skin between visits.
International patients can be seen at our Incheon Airport (Yeongjongdo) location near ICN, with English-language support and Medical Director Dr. Sunbeen Kim overseeing care. This is convenient for travelers arriving or departing through Incheon Airport. The team helps coordinate timing around your flight schedule.
For a single body area, 1 to 2 days is usually comfortable, covering a consultation, the session, and a short review. Because results build over months, no long stay is required. Our Incheon Airport location is convenient for patients on a stopover or a short trip to Seoul.
Yes, flying within a day or so is generally fine because body Ultherapy is non-invasive with limited downtime. Any mild swelling or tenderness is temporary. Staying hydrated and protecting treated skin from strong sun helps, and the clinic’s doctors give travel-friendly aftercare, which suits our Incheon Airport patients well.
Because results develop over 2 to 6 months, most follow-up is a simple progress review that can be done remotely in English between trips. Your treatment notes are kept on file for continuity. Many international patients time a maintenance session with a later visit through Incheon Airport.
