What is Body Sofwave?

Body Sofwave is the body-area application of Sofwave’s ultrasound technology, used to firm and tighten skin that has become lax on areas such as the upper arms, abdomen, knees, and elbows. It targets crepey, loose skin and mild laxity without surgery, needles, or downtime, making it a practical option for body skin that has lost elasticity with age or weight change.

Like facial Sofwave, the body treatment uses SUPERB (Synchronous Ultrasound Parallel Beam) technology to heat the mid-dermis at around 1.5 mm depth, the layer where collagen and elastin sit. The controlled heating prompts the skin to build new fibers, so treated areas become tighter and smoother over the following weeks while a cooling system protects the surface.

Body Sofwave is a skin-tightening treatment, not a fat-removal procedure, so it is best for people who want firmer skin rather than significant contour or volume change. Reberry Clinic offers Body Sofwave across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport), with English-language consultation and a plan tailored by the clinic’s doctors.

The SUPERB ultrasound technology for the body

Body Sofwave uses SUPERB synchronous ultrasound parallel beam technology. Seven transducers in direct contact with the skin fire parallel ultrasound beams that converge to heat a defined band of the mid-dermis to roughly 60-70 degrees Celsius at about 1.5 mm depth. On the body, this controlled thermal effect partially denatures existing collagen and elastin in lax areas, prompting a wound-healing response that builds new, organized fibers over several weeks. An integrated cooling system (Sofcool) keeps the surface protected, so the energy concentrates in the dermis where it remodels tissue. Because larger body areas are treated in passes, coverage is planned so each zone receives even energy at the target depth, supporting consistent tightening across the arm, abdomen, or knee.

How Body Sofwave Works

Sofwave treatment device
Mapping the area

The clinic’s doctors mark the arm, abdomen, or knee zone and set energy levels for your skin, planning the 1 session.

The Sofcool system pre-cools the surface so the skin stays protected while energy reaches about 1.5 mm depth.

Seven transducers deliver synchronous ultrasound beams that heat the mid-dermis to roughly 60-70 degrees Celsius.

The controlled heat triggers neocollagenesis, with new collagen and elastin forming over about 12 weeks.

Treated skin firms progressively over 6 to 12 weeks, with continued improvement reported by many patients.

The Process

Your Body Sofwave Journey

Consultation

The clinic’s doctors assess the laxity of your arms, abdomen, or knees, then design a single-session plan, explained in English.

A typical Body Sofwave session takes about 30 to 60 minutes depending on the size and number of areas treated.

Most patients complete treatment in 1 visit and return to normal activities the same day.

Tightening builds over 6 to 12 weeks as new collagen forms, with improvement continuing for several months.

Effects often last around a year; sun protection, hydration, and stable weight help maintain the result.

Good Candidates

Cautions & Contraindications

Scientific Evidence

Sofwave’s parallel-beam ultrasound has FDA clearance that includes improving the appearance of skin laxity on the upper arms, supporting its body use. Histology of high-intensity parallel ultrasound shows increased collagen and elastic fiber in the mid-dermis, the mechanism behind tightening. A facial-laxity study reported that about 92% of treated patients showed improvement in tightening and/or wrinkle reduction, and a comparative review describes synchronous parallel-beam ultrasound delivering consistent mid-dermal heating at around 1.5 mm. An Asian-patient study of the same device reported good tolerability with no adverse events.

FAQ

Frequently Asked Questions

What is Body Sofwave and how does it tighten skin?

Body Sofwave uses SUPERB synchronous parallel-beam ultrasound to heat the mid-dermis at about 1.5 mm on body areas, triggering new collagen and elastin so loose skin firms gradually. The technology is the same as facial Sofwave, applied to larger zones like the arms and abdomen, with no cutting and no general anaesthesia.

Body Sofwave is commonly used on the upper arms, abdomen, above the knees, and elbows, where skin becomes crepey or lax. It tightens skin rather than removing fat, so it suits firmness goals. Your doctor confirms which areas are suitable, and may suggest a contouring option such as our Onda page where fat is the concern.

Adults with mild to moderate skin laxity or crepey texture on the arms, abdomen, or knees are ideal candidates, especially those wanting a non-surgical option. People with significant excess fat may need a different approach. A consultation confirms suitability and whether tightening or contouring better matches your goal.

Most patients feel brief warmth or a tingling sensation as each pulse is delivered, lasting only seconds. The built-in surface cooling and optional numbing improve comfort across larger body areas. Any discomfort is temporary and ends as soon as the session finishes, with no lingering pain once you leave the clinic.

Downtime is minimal, and most patients resume normal activities the same day. Some experience mild redness, slight swelling, or temporary tenderness in the treated area for a few hours up to a day or two. There are no bandages, so international visitors can usually continue their plans shortly afterwards.

Some firmness may appear early, but the main improvement builds gradually over 6 to 12 weeks as collagen forms, and many patients notice continued change for several months. Results are progressive rather than instant after one session, so patience helps. Body areas can take a little longer than the face to show full effect.

Most patients need a single session per area, with energy and coverage tailored to your skin and the body zone at consultation. Some choose a maintenance treatment after about a year. Your doctor decides the right approach based on the area size, laxity, and your goals rather than a fixed number.

Results commonly last around 12 months, though this varies with age, skin quality, weight stability, and lifestyle. Because Body Sofwave stimulates your own collagen, natural ageing continues over time. Many patients schedule a maintenance session annually, and steady weight plus a good skin care routine helps extend firmness.

No, Body Sofwave is a skin-tightening treatment, not a fat-removal procedure, so it firms loose skin rather than reducing volume. If localized fat or cellulite is your main concern, a microwave option may suit better; you can read our Onda page. Your doctor advises which goal each treatment addresses.

Yes, Body Sofwave is often paired with radiofrequency body treatments or contouring procedures for complementary effects, sequenced safely by your doctor. For example, some patients combine firmness from Sofwave with a body option such as our RF body skin tightening. Your doctor will advise the order and timing.

Body Sofwave has a well-documented safety profile when performed by trained operators, with side effects usually limited to temporary redness, swelling, or tenderness. The integrated cooling protects the skin surface, and clinical studies of the technology reported no serious adverse events. Your doctor reviews your medical history to confirm the treatment is appropriate for you.

Expect mild redness, slight swelling, and temporary tenderness in the treated area for a few hours to a day or two. Small raised areas or bruising are less common and self-resolving. Serious complications are rare when an experienced operator uses appropriate settings. Your doctor reviews your history beforehand to minimise any risk.

Yes, Body Sofwave suits a wide range of skin tones, including Asian skin, because the ultrasound energy targets the dermis rather than melanin in the surface. This lowers the risk of pigment changes seen with some light-based devices. Clinical studies of the parallel-beam technology, including Asian patients, reported good tolerability with no adverse events.

A single Body Sofwave session needs only about 2 to 3 days, covering consultation, treatment, and an optional brief review. Because downtime is minimal, you can combine it with a related option like our RF body skin tightening if advised. Our English team coordinates timing so it fits a short trip.

Yes, flying soon after Body Sofwave is generally fine, often the same day, because it is non-invasive with minimal swelling. Stay hydrated during the flight and protect treated skin from sun on arrival. If you had several large areas treated, your doctor will advise any specific timing before you travel home.

International patients can have remote check-ins in English after returning home, with progress reviewed over the weeks results develop. If you want complementary body care later, you can explore our body rejuvenation options. Your treatment plan and notes are kept on file for any future visit.

Body Sofwave, body radiofrequency, and microwave body treatments use different energy types, so the right choice depends on whether your goal is skin firmness or contour.
