Most patients need just 1 Sofwave session, with results building over 2 to 3 months; some choose an optional maintenance treatment after about a year.
Most patients need only 1 Sofwave session to see meaningful lifting, with the full effect building over 2 to 3 months as collagen forms. Unlike some treatments that require a stacked course, a single visit is usually enough; a maintenance session after roughly 12 months can help sustain results, but it is optional and based on your goals.
One-on-One guidance from a dedicated doctor, ensuring your skin is professionally monitored and treated from start to finish.
Fluent assistance in English, Japanese, and Chinese, making communication clear, respectful and comfortable for international patients.
Over 100,000 patients worldwide have received our personalized dermatological care, highlighting our expertise and reliable results.
Sofwave is designed as a single-session treatment for most people, which is one of its main practical advantages. In one visit, the device delivers enough controlled ultrasound energy to trigger a meaningful collagen-rebuilding response, and that response continues working under the skin for weeks afterward. This is different from treatments that need a planned series of 3 to 6 sessions spaced weeks apart to reach their goal.
That said, a small number of patients with more advanced laxity, or those who simply want to maximize the effect, may choose to add a second session or a later maintenance treatment. The decision depends on your starting point, your goals and how your skin responds. Because results build gradually, the clinic usually reviews the outcome a few months later before suggesting any further treatment, rather than booking extra sessions upfront.
Reberry Clinic is a dermatology clinic that serves international patients across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport) with English-speaking support. The clinic’s doctors assess your skin honestly and tell you whether a single session is likely to meet your goals, so you can plan a short, efficient trip to Seoul.

Sofwave uses SUPERB synchronous ultrasound parallel beams to heat the mid-dermis at a consistent depth of about 1.5 mm, while a built-in cooling system protects the surface. In a single session the doctor delivers multiple passes across the treatment area, placing enough energy points to stimulate new collagen and elastin without needing to repeat the process weeks later.
The collagen response then matures over 2 to 3 months, which is why one session produces a progressive lift rather than an instant change. The clinic’s doctors decide the number of passes and coverage based on your anatomy. They will also explain how Sofwave compares with options like micro-focused ultrasound so the session plan matches your goals.

A doctor evaluates your laxity and goals to judge whether 1 session is likely to be enough.
For most patients, 1 session with multiple passes delivers the planned energy in around 30 to 45 minutes.
The lift develops over 2 to 3 months, so progress is reviewed before any extra treatment is considered.
A small number with advanced laxity may add 1 more session, decided after seeing the first result.
An optional maintenance treatment after about 12 months helps sustain results as natural aging continues.

See representative outcomes from Reberry Clinic. Results build gradually and vary by individual; your plan is assessed at consultation.










An English-language consultation assesses your skin and confirms whether 1 session is likely enough within a single visit.
After cleansing, the doctor delivers the planned passes; a session commonly takes around 30 to 45 minutes.
Most patients need only 1 session, so it fits a short Seoul trip without repeat visits.
The lift builds over 2 to 3 months, after which progress is reviewed before any further treatment.
Results often last around a year; an optional maintenance session and good skincare help sustain them.



Most patients need only 1 Sofwave session to see meaningful lifting, with results building over 2 to 3 months. A stacked course is not usually required. A small number with advanced laxity may add a second session, decided after the first result. Your plan is confirmed during the Sofwave consultation.
One session delivers enough controlled ultrasound energy to trigger a lasting collagen-rebuilding response, which then matures over 2 to 3 months. This differs from treatments needing 3 to 6 spaced visits. Because the effect builds gradually, the clinic reviews your result before suggesting more rather than booking extra sessions upfront.
A second session is occasionally helpful for advanced laxity or when someone wants to maximize the effect, and it is decided after seeing how your skin responds to the first treatment. It is not routine. The clinic’s doctors review your result a few months later before recommending any additional session.
Many patients choose an optional maintenance session after about 12 months, since natural aging continues and results gradually soften. Repeating sooner is not usually needed. Your ideal interval depends on your skin and goals and is reviewed during the Sofwave consultation rather than fixed for everyone.
Some early firmness can appear within the first few weeks, but the main lift from a single session builds over 2 to 3 months as new collagen matures. This gradual change is expected. The timeline for your face is mapped at the assessment so you know what to expect after one visit.
Results from a single session often last around twelve months, though this varies with age, skin laxity and lifestyle. A maintenance session and good skincare help sustain the effect. Because longevity differs per person, expectations are individualized at consultation rather than promised as one fixed duration.
Most patients find a Sofwave session generally comfortable, feeling warmth and brief pulses while cooling protects the surface, even though it covers the full area in one visit. Afterward there is usually only mild warmth for a few hours. Comfort options are reviewed during the Sofwave assessment.
Downtime is minimal after a session; most patients have only mild redness and warmth that fade within a few hours and return to normal activities the same day. Because there is just one session, there is only one short recovery period, which is convenient for travelers fitting it into a trip.
Yes, Sofwave is often combined with treatments like skin boosters or injectables, and the doctor sequences them safely within your plan. Combining can address texture and volume alongside lifting. Your suitability for combinations, and whether to do them together or stage them, is reviewed at the consultation before treatment.
All three are typically single-session treatments with optional maintenance later, but they target different depths and suit different goals. Sofwave focuses on the mid-dermis. You can compare Ultherapy Prime and Thermage FLX with the team to choose the right single-session option.
Yes, because Sofwave delivers energy at a fixed mid-dermis depth and protects the surface with cooling, a single session suits a wide range of skin tones with a low risk of pigmentation issues. Suitability is still confirmed individually. Your skin is assessed before the session is planned at the clinic.
Aftercare is simple: keep the skin clean, moisturized and protected with SPF, and avoid heat, saunas and vigorous exercise for about 24 hours. There is no wound to manage and only one recovery period. The clinic provides written aftercare so international patients can follow it from home.
Yes, Reberry Clinic serves international patients with English-speaking support across three Seoul-area locations, including one near Incheon Airport. Because most patients need only one session, it fits a short trip easily. Message us on WhatsApp to plan your single Sofwave visit.
Because most patients need only 1 session with recovery measured in hours, even a 1 to 2 day trip works; the session itself usually takes around 30 to 45 minutes. There is no required multi-day course. Our team helps schedule the single visit around your itinerary.
Yes, most patients fly the same or next day after their single session, since downtime is minimal and any redness fades quickly, while the lift develops gradually after you return. You receive a written aftercare plan so you can follow up on your Sofwave results from abroad.
Not always; for most people a single session reaches the effect their skin can produce, and adding sessions offers limited extra benefit unless laxity is advanced. The doctor advises honestly rather than selling extra visits. Whether more than one session helps you is judged after your first result matures.
No, maintenance is optional and usually considered after about 12 months once you see how your results hold. Booking a course upfront is not necessary. The clinic reviews your skin over time and you decide on any maintenance session later, based on your goals rather than a fixed schedule.
