Body Sofwave delivers SUPERB ultrasound energy through 7 parallel transducers into the mid-dermis at about 1.5mm to firm lax skin, usually in a single non-surgical session.
Body Sofwave is a non-surgical ultrasound treatment that firms lax skin on areas like the arms, abdomen, and above the knees. It uses SUPERB synchronous parallel ultrasound to heat the mid-dermis and stimulate new collagen, typically in one session with minimal downtime. At our Gangnam (Seoul) location, Dr. Yoongon Ryu confirms suitability in English at consultation.

Over 100,000 patients worldwide have received our personalized dermatological care, highlighting our expertise and reliable results.
Body Sofwave applies the Sofwave ultrasound platform to areas below the face and neck, tightening skin that has become lax through ageing, weight change, or reduced elasticity. It is a non-surgical, non-invasive approach that works by heating the mid-dermis to trigger the skin’s own collagen-remodelling response, so improvement builds gradually rather than instantly.
Sofwave uses SUPERB technology, short for Synchronous Ultrasound Parallel Beam, delivering energy through 7 parallel transducers directly on the skin to a controlled depth of roughly 1.5mm in the mid-dermis. On the body, this suits areas of mild to moderate skin laxity such as the upper arms, the abdomen, above the knees, and the elbows, where the goal is firmer, smoother-looking skin rather than fat removal.
At Reberry Clinic, body Sofwave is consultation-led. At our Gangnam (Seoul) location, Dr. Yoongon Ryu and the clinic’s doctors assess your skin laxity, confirm the treatment fits your goal, and explain a realistic timeline in English. Because Sofwave firms skin rather than reducing volume, they will tell you honestly when a different approach suits you better. We support international patients across our three Seoul-area locations.
Sofwave uses SUPERB (Synchronous Ultrasound Parallel Beam) technology, in which 7 parallel transducers sit in direct contact with the skin and deliver ultrasound energy to a precise depth of about 1.5mm in the mid-dermis. Unlike focused ultrasound that targets deeper layers, this parallel-beam approach heats a controlled zone within the dermis itself, creating small thermal coagulation points that prompt the body to produce new collagen and elastic fibres as it heals. An integrated cooling mechanism protects the skin surface during treatment for comfort. Because the response is biological, the skin firms gradually over roughly 6 to 12 weeks as collagen remodels, and many people continue to see improvement for several months. On body areas such as the arms, abdomen, and above the knees, a single session is often enough, though larger or more lax areas may benefit from a second session. The energy targets skin laxity, not subcutaneous fat, so it is a firming tool rather than a fat-reduction device, which is why the clinic’s doctors confirm your goal and skin condition before recommending it.

The clinic’s doctors grade laxity on the target area and confirm the goal is firming, since Sofwave addresses skin, not the underlying fat.
The area is cleansed and topical numbing is applied for comfort, usually about 20 to 30 minutes before treatment begins.
7 parallel transducers deliver ultrasound to the mid-dermis at about 1.5mm, with built-in cooling protecting the skin surface throughout.
A body area is typically treated in about 30 to 60 minutes depending on size, most often in a single session per area.
Over roughly 6 to 12 weeks the skin builds new collagen, so firming develops gradually and can keep improving for several months.

At our Gangnam (Seoul) location, the clinic’s doctors grade your skin laxity, confirm the goal is firming, and explain the timeline in English.
After about 20 to 30 minutes of numbing, the body area is treated in roughly 30 to 60 minutes depending on its size.
Many body areas need only a single session, though larger or more lax areas may benefit from a second session your doctor plans.
Firming develops gradually over about 6 to 12 weeks as collagen remodels, with improvement sometimes continuing for several months.
Results can last many months to over a year; the new collagen still ages, so occasional maintenance and good skin care help sustain firmness.
Body Sofwave is a non-surgical ultrasound treatment that firms lax skin on areas like the arms, abdomen, and above the knees. It uses SUPERB parallel ultrasound to heat the mid-dermis and stimulate new collagen. You can read the full overview on our Sofwave page before your visit.
Body Sofwave is performed at our Gangnam (Seoul) location with Dr. Yoongon Ryu and the clinic’s doctors, in central Seoul, Korea, about 2 minutes from Gangnam Station exit 10. International patients are supported in English, and the team assesses your skin laxity before confirming that the treatment fits your goal and area.
Sofwave uses SUPERB technology, delivering ultrasound through 7 parallel transducers to about 1.5mm in the mid-dermis. This controlled heat prompts the body to build new collagen and elastic fibres as it heals, so skin firms gradually. Built-in cooling protects the surface, which keeps the treatment comfortable during each pass.
Body Sofwave suits mild to moderate skin laxity on areas such as the upper arms, the abdomen, above the knees, and the elbows. It targets skin firmness rather than fat, so the goal is smoother skin. The full Sofwave overview explains the areas, and your doctor confirms suitability at consultation.
No, Sofwave firms lax skin and does not reduce fat or cause weight loss. Its energy targets the mid-dermis where collagen forms, not the deeper fat layer. If your goal involves localized fat, a different approach may suit you better, which our body tightening page can help you compare.
Many body areas need only a single Sofwave session, which is one of its advantages, though larger or more lax areas may benefit from a second. Your doctor confirms the plan after assessing your skin. Because results build gradually, they usually review the area a few months later before deciding on any additional session.
Most people find body Sofwave tolerable, describing brief warmth or a tingling sensation during energy delivery. Topical numbing is applied beforehand and integrated cooling protects the skin surface for comfort. Any sensitivity settles quickly after the session. Your doctor adjusts settings to keep the treatment comfortable while still effective for your skin.
Downtime is minimal, with most people returning to normal activity right away. You may notice mild redness or slight swelling in the treated area for a few hours, which settles on its own. Because the treatment is non-surgical with no incisions, there is no lengthy recovery, making it convenient for busy schedules and travellers.
Firming develops gradually over about 6 to 12 weeks as the skin remodels collagen, rather than immediately after treatment. Many people continue to notice improvement for several months. Your doctor sets this expectation at consultation so you understand that Sofwave produces a natural, progressive result rather than an instant change.
Results can last many months to over a year, depending on your skin and lifestyle. Because the newly formed collagen still ages naturally, the effect is long-lasting rather than permanent. Occasional maintenance sessions and good skin care help sustain firmness. Your doctor advises on timing for any top-up based on how your skin responds.
Sofwave uses SUPERB ultrasound to heat the mid-dermis, often in a single session, while RF body tightening uses radiofrequency heat, usually across a planned series. Both firm skin through different energy. Your doctor recommends the better fit for your laxity. You can review the alternative on our RF body tightening page.
Good candidates are adults with mild to moderate skin laxity who want non-surgical firming, not fat reduction. Very severe laxity may respond better to a surgical option, and your doctor will say so honestly. A consultation grades your skin and confirms whether body Sofwave suits your specific area and expectations before you commit.
Body Sofwave is generally considered safe when performed by a trained doctor on suitable skin, with integrated cooling protecting the surface. Side effects are usually limited to temporary redness or swelling. A consultation screens for contraindications such as implants or active skin problems in the area, which is why proper assessment is part of every plan.
Yes, body Sofwave can be part of a broader plan, for example paired over time with other firming or skin-quality treatments your doctor recommends. They sequence treatments so the skin is not over-stressed. You can explore complementary options through our body rejuvenation page and discuss a combined plan at consultation.
For a single session, 1 to 2 days in Seoul is usually enough, allowing a consultation, the treatment, and a brief review. Since downtime is minimal, many international patients treat and keep travelling, even pairing it with other firming options. Our English-speaking team coordinates timing around your schedule in Korea.
Yes, flying within a day of body Sofwave is generally fine because the treatment is non-surgical with minimal downtime. Any mild redness or swelling settles quickly. Keep the treated skin hydrated and protected from strong sun while you travel. Your doctor gives specific aftercare so your skin remodels comfortably during and after your journey.
