Body Ultherapy is a non-surgical skin-firming treatment that applies Ultherapy Prime, a micro-focused ultrasound with visualization (MFU-V) device, to areas below the neck such as the abdomen, upper arms, and above the knees. Instead of cutting or removing tissue, it delivers focused ultrasound energy to precise depths, prompting the skin’s own collagen to renew and gradually tighten over the following months.
The key advantage on the body is the visualization screen. Before each pass, the doctor can see the tissue layers, so energy is placed where there is enough treatable depth and avoided where there is not. This matters on the body, where tissue thickness varies far more than on the face, and it helps target the deeper connective-tissue laxity that surface treatments cannot reach.
At our Myeongdong (Seoul) location, body Ultherapy is doctor-led. Dr. Seung Jae Baek, Medical Director, and the clinic’s doctors assess each area and tailor the depths and lines to your body. Located at 5, Myeongdong 10-gil, Jung-gu, about 5 minutes from Myeongdong Station, the clinic offers English-language support for international patients throughout the process.
Ultherapy Prime focuses ultrasound energy into tiny thermal coagulation points at set depths, typically 4.5 mm to reach deeper connective tissue, and 3.0 mm and 1.5 mm within the dermis. On the body, the DEEPSEE visualization screen lets the doctor see the tissue layers in real time before each pass, so energy lands in tissue with enough depth to treat safely. Each point briefly heats tissue above 60 degrees Celsius, creating controlled micro-injuries that the body repairs by laying down fresh collagen and elastin over roughly 90 days. Because body tissue is thicker and areas are larger than the face, the doctor adjusts the depth settings and the number of ultrasound lines per zone, using more lines to cover a full abdomen than a small area above the knees. The energy never damages the skin surface, which is why downtime stays minimal. This deep, precise placement is what allows body Ultherapy to address laxity that lives beneath the skin rather than only at the surface.

The doctor examines each zone (abdomen, arms, knees) and grades laxity, choosing among the 3 depths (1.5, 3.0, 4.5 mm) for your tissue.
Using the DEEPSEE screen, the doctor sees the tissue before every pass, so ultrasound energy is placed only where there is enough depth.
Focused ultrasound creates thermal coagulation points that heat tissue above 60 degrees Celsius at the chosen depth, one ultrasound line at a time.
Over about 90 days, the treated points prompt new collagen and elastin, which gradually firms and supports the lax body skin.
At follow-up, the doctor checks each area and advises whether 1 further session would add benefit for laxer zones.

At our Myeongdong (Seoul) location, the clinic’s doctors assess each area, grade laxity, and explain the plan and expected timeline in English.
A single-area body session usually takes about 30 to 60 minutes; combining several zones extends the appointment accordingly.
Most patients have 1 session per area, so the plan is mapped by zone rather than as an open-ended course of many visits.
Firming builds gradually over about 2 to 3 months as new collagen forms, and your doctor reviews each area at follow-up.
Results can last many months; because skin keeps ageing, occasional maintenance and good skincare help sustain the effect over time.



Body Ultherapy is a non-surgical treatment using micro-focused ultrasound with visualization to firm lax skin on the abdomen, arms, and knees. It stimulates collagen at set depths for gradual tightening. You can read the full overview on our Ultherapy Prime page before booking a consultation.
Common body areas include the abdomen, upper arms, and above the knees, where mild to moderate laxity often appears. The visualization screen helps the doctor confirm each area has enough treatable depth. During consultation, your doctor maps which zones suit you and how they would be prioritised for your goals.
It delivers focused ultrasound to precise depths, creating tiny thermal points that heat tissue above 60 degrees Celsius. Over about 90 days, the body repairs these points with fresh collagen and elastin, which gradually firms lax skin. Learn more about the device on our Ultherapy Prime page.
Most patients feel warm pulses and brief tingling as the energy is delivered, rather than sharp or lasting pain. Comfort is managed with settings and topical measures suited to each area. Because the body has thicker tissue, sensations vary by zone, which your doctor explains before starting the session.
Downtime is typically minimal because the skin surface is not damaged. Some patients notice temporary redness, mild swelling, or tenderness for a few days, especially on larger areas. Most people resume normal activity quickly, and your doctor gives simple aftercare advice for the treated zones on the day.
Most patients start with 1 session per body area, then review results once collagen renews over 2 to 3 months. Laxer areas may benefit from a repeat months later. Your doctor assesses each zone and advises whether one session is enough or a follow-up would add benefit for you.
Visible firming usually builds gradually over about 2 to 3 months as new collagen forms, rather than appearing immediately. Some patients notice early tightening sooner. Because body areas respond at different rates, your doctor reviews each zone at follow-up and advises whether further treatment would help.
Results can last many months as new collagen supports the tissue, but skin continues to age, so it is not a one-time fix. Occasional maintenance sessions and consistent skincare help sustain firmness. Your doctor sets realistic expectations for each treated area during your consultation and follow-up reviews.
Body Ultherapy Prime focuses ultrasound into deeper connective tissue, while body Thermage FLX uses radiofrequency for broad surface firming and Sofwave targets the mid-dermis. The right choice depends on your area and laxity. You can compare related options such as Sofwave before deciding.
Adults with mild to moderate laxity on the abdomen, arms, or knees, and enough treatable tissue, are usually suitable candidates. Very thin tissue may not offer safe depth. A consultation confirms candidacy, maps the areas, and sets realistic expectations for what body Ultherapy can achieve for you.
Yes, body Ultherapy is often planned alongside other firming or contouring options, with sequencing chosen for comfort and results. Some patients pair it with RF-based body work over separate visits. Your doctor may discuss body rejuvenation options to build a balanced, staged plan.
Temporary redness, mild swelling, tenderness, or short-lived tingling can occur and usually settle within days. Serious effects are uncommon when a trained doctor uses visualization to place energy safely. Your health history and target areas are reviewed at consultation to keep the treatment appropriate for you.
Ultherapy works below the surface, so it is generally suitable across skin tones, including deeper tones, because it uses ultrasound rather than light. Tissue thickness and laxity matter more than colour. Your doctor assesses your skin and tissue at consultation to tailor depths and expectations appropriately for your body.
Aftercare is simple: keep skin moisturised, avoid intense heat or firm massage on treated areas for a few days, and use sun protection. Most patients resume normal routines quickly. A supportive skin care routine helps protect and prolong your results between body sessions.
Two to three days in Seoul is comfortable for a first session, allowing a consultation, the treatment, and a brief review. Because most body plans are single-session per area, many international patients complete treatment on one trip. Our English-speaking Myeongdong team helps coordinate timing around your travel.
Yes, flying within a day or so is generally fine because body Ultherapy is non-invasive with minimal downtime. Treated skin may feel tender briefly, so stay hydrated and protect it from strong sun. If several areas were treated, your doctor gives simple aftercare guidance to follow while travelling.
International patients can complete body Ultherapy in one visit and check in remotely in English as results develop over the following months. If a repeat is worthwhile, it can be planned for a later trip. You can also maintain firmness with a home skin care routine between visits.
