What is body Sofwave?

Body Sofwave is a non-invasive treatment that firms and tightens loose skin on the body using ultrasound energy. It applies the same SUPERB technology used on the face, delivering synchronous parallel ultrasound beams to the mid-dermis at a fixed depth of about 1.5 mm, where controlled heating stimulates the skin to build new collagen and elastin over the following weeks.

It is important to be clear about what body Sofwave does and does not do. It is a skin-tightening and firming treatment, not a fat-removal or weight-loss procedure, because the energy is kept in the dermis and does not target the deeper subcutaneous fat layer. That dermal focus is also why the pivotal data reported no fat-loss adverse events. Common body targets include mild crepey skin on the upper arms, above the knees, the abdomen, and around the elbows.

At Reberry Clinic, body Sofwave is consultation-led, with a doctor grading the area and planning your sessions. For international patients searching near Hongdae (Hongik Univ.) Station, care is provided across our Seoul locations, Gangnam and Myeongdong, both easily reached from 홍대입구역, with full English-speaking support throughout.

Sofwave treatment

How the SUPERB ultrasound technology works on the body

Sofwave uses SUPERB (Synchronous Ultrasound Parallel Beam) technology, in which seven parallel transducers sit in direct contact with the skin and deliver ultrasound energy to the mid-dermis at roughly 1.5 mm. On the body, this creates precise thermal coagulation zones within the dermis that trigger a natural wound-healing and remodelling response, building collagen and elastin that firm and tighten the treated skin over about 12 weeks. Integrated cooling protects the skin surface throughout, which helps comfort and keeps downtime minimal. Because the treatment is delivered as lines of coverage, larger body areas are treated with more lines while smaller zones need fewer. The key mechanical point is depth: at 1.5 mm the energy remains in the dermis and does not reach the deeper subcutaneous fat, so body Sofwave firms skin rather than reducing fat volume. This makes it suited to mild and moderate laxity, not to weight reduction, and is why a doctor first assesses whether skin tightening is the right goal for your area.

How It Works

How Body Sofwave Works

Sofwave treatment
Assess the area

A doctor grades laxity on the target zone and confirms body Sofwave suits you, since it firms skin at 1.5 mm rather than reducing fat.

The treatment area is planned as lines of coverage, so larger zones like the abdomen use more transducer lines than small areas.

Seven parallel transducers heat the mid-dermis to controlled thermal zones at about 1.5 mm, with cooling protecting the surface.

The heating triggers remodelling that builds new collagen over about 12 weeks, gradually firming the treated skin.

Results are reviewed around 12 weeks, and 1 session suits mild laxity while firmer areas may need a short series.

The Process

Your Body Sofwave Journey

Consultation

The clinic’s doctors assess the area, grade laxity, confirm body Sofwave firms skin rather than removing fat, and explain the plan in English.

A body session typically takes about 30 to 60 minutes depending on area size, with numbing cream and integrated cooling for comfort.

Many mild cases are treated in a single session, while larger or firmer areas may be planned as a short series over weeks.

Firming builds gradually over about 12 weeks as new collagen forms, and your doctor reviews progress at that point.

Results often last around a year and vary by skin, so occasional maintenance and simple sun-protection aftercare help sustain firmness.

Cautions & Contraindications

Scientific Evidence

In a study of the 1.5 mm parallel-beam device, 36 subjects aged 30 to 80 showed measurable skin tightening at 1 and 3 months, and a Korean histology study found mid-dermis collagen fibre density rose from 0.849 to 1.432 about 2 months after treatment. The facial pivotal trial recorded an 88% improvement in lines and wrinkles at 12 weeks with no serious adverse events, and because energy stays in the dermis, no fat-loss effects occurred, confirming body Sofwave firms skin rather than reducing fat. Cellulite and laxity studies extend the evidence across larger body surfaces.

FAQ

Frequently Asked Questions

What is body Sofwave and how does it work?

Body Sofwave is non-invasive skin tightening that uses SUPERB parallel ultrasound to heat the dermis at about 1.5 mm, stimulating collagen to firm loose skin. It treats the skin layer, not fat. You can review the underlying technology on our Sofwave page before your consultation.

Patients searching near Hongdae (Hongik Univ.) Station are cared for at our Seoul locations, Gangnam and Myeongdong, both easily reached from 홍대입구역. English-speaking staff assess the body area and plan your Sofwave treatment there, with a doctor grading laxity rather than selling a fixed online package.

No, body Sofwave is a skin-tightening treatment, not a fat-removal or weight-loss procedure. Its energy stays in the dermis at about 1.5 mm to firm loose skin, which is why no fat-loss effects are expected. If fat reduction is your goal, your doctor can discuss different, appropriate options at consultation.

Body Sofwave suits areas with mild to moderate laxity, such as upper arms, above the knees, the abdomen, and around the elbows. The right zones depend on your skin and goals, confirmed by assessment. You can compare firming options like RF body skin tightening at consultation.

Body Sofwave is generally well tolerated because integrated cooling protects the surface while ultrasound heats the dermis. Numbing cream is applied and comfort is checked during the session. Most people describe warmth and brief prickling rather than pain, and your doctor adjusts settings to keep the treatment comfortable for your area.

Downtime is minimal, and most people return to normal routine the same day, sometimes with brief redness or mild warmth in the area. There is no surgical recovery. Your doctor gives simple aftercare, and if a provider implies there is never any recovery at all, treat that as marketing rather than a medical fact.

Mild laxity may respond to a single session, while larger areas or more pronounced looseness can benefit from a short series spaced 4 to 8 weeks apart. The number depends on the area and your goal, which a doctor decides at consultation. Firming continues to build for weeks after each session.

Firming builds gradually over about 12 weeks as new collagen forms, not immediately after treatment. Studies of the 1.5 mm device documented measurable tightening at 1 and 3 months. Your doctor sets this timeline clearly so you judge results at the right point rather than expecting an instant change.

Results often last around a year, though longevity varies by skin quality, area, and lifestyle, so it is not a one-time permanent fix. Skin ageing continues naturally, so periodic maintenance helps sustain firmness. Your doctor suggests realistic maintenance timing based on how your area responds over time.

Body Sofwave uses dermal ultrasound at about 1.5 mm for precise firming, while radiofrequency heats a wider and often deeper tissue volume. Neither is universally superior; the right choice depends on your laxity and area. You can explore RF body skin tightening alongside it when planning.

Common effects are temporary redness, mild swelling, or warmth in the treated area, which usually settle quickly. Serious events were not reported in pivotal data. A good clinic reduces risk by matching energy settings to your skin type, so ask how they manage the usual mild effects rather than expecting none at all.

Body Sofwave has been studied across Fitzpatrick skin types II to IV, and a good clinic confirms suitability by assessing your skin and the area first. Deeper tones may need conservative settings, which is exactly the tailoring a doctor should provide. Suitability and safe settings are confirmed at consultation, not assumed from a package.

Yes, it is often combined with treatments targeting different concerns or layers, and a doctor sequences them safely so skin is not over-stressed. For broader body firming, options such as body rejuvenation approaches may be discussed alongside body Sofwave at your consultation.

Aftercare is simple: protect the treated area, avoid intense heat like saunas briefly, and use sunscreen on exposed skin. Some patients add supportive products, which is optional. A skin care routine helps maintain results, and your doctor recommends what suits your skin between sessions.

For most patients, 1 to 2 days in Seoul is comfortable, allowing a consultation, the session, and a short review, since downtime is minimal. Our English-speaking team helps coordinate timing around your travel from the Hongdae area, and many international patients pair it with other planned skincare visits.

Yes, flying within a day is generally fine because body Sofwave is non-invasive with minimal downtime. The treated area may feel warm briefly, so wear comfortable clothing and use sunscreen on exposed skin. Your doctor gives tailored aftercare before you travel so you are prepared for the journey home.

International patients can complete body Sofwave in one visit and receive remote check-ins in English between trips, so your plan stays on track from abroad. Your treatment notes are kept on file for continuity. You can also maintain results with a home skin care routine set at consultation.
