Sofwave results build over about 12 weeks as collagen and elastin form and typically last around a year, with longevity shaped by age, skin laxity and aftercare.
Sofwave results typically last around a year, building gradually over about 12 weeks as new collagen and elastin form. Because the effect comes from your own tissue remodeling, longevity varies with age, skin laxity and lifestyle. It is not a one-time fix; a maintenance session, sun protection and good skincare help sustain the lift over time.
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 produces gradual, collagen-based results rather than an instant change, and most patients enjoy the effect for around a year. After treatment, some firmness can appear early, but the main lift develops over roughly 12 weeks as the deposited ultrasound energy stimulates new collagen and elastin in the mid-dermis. Once that tissue remodeling matures, the tightening and lift hold for several months before the natural aging process gradually continues.
How long the effect lasts is individual. Younger skin with milder laxity and good collagen reserves tends to hold results longer, while more advanced laxity, sun exposure, smoking and weight changes can shorten it. Because the result depends on your own biology, it is not a permanent change; it is a refresh of your skin’s structure that ages alongside you. This is why clinics frame Sofwave longevity as a realistic range rather than a fixed guarantee.
Reberry Clinic is a dermatology clinic where energy-based lifting is performed by the clinic’s doctors, and it serves international patients across three Seoul-area locations (Gangnam, Myeongdong, Incheon Airport) with English-speaking support. At consultation the team explains the expected timeline and how maintenance fits your skin, so you can plan results around future visits to Seoul.

Sofwave works by SUPERB synchronous ultrasound parallel beam technology: seven parallel transducers deposit fractional zones of heat at a controlled mid-dermis depth of about 1.5 mm, triggering a healing response that lays down new collagen and elastin over the following weeks. Because the result is built from your own remodeled tissue, it appears gradually over about 12 weeks and then lasts as that new structure persists. You can read more about how Sofwave works on its treatment page.
Longevity also depends on choosing the right modality for your depth of laxity. The clinic’s doctors will explain when a deeper or different option such as micro-focused ultrasound or monopolar radiofrequency may give a more durable result for your goals, so the plan is matched to how long you want the lift to hold.

In 1 session, energy is deposited at the mid-dermis depth of about 1.5 mm across the planned passes.
Some tightening can appear within the first 2 to 4 weeks as the initial healing response begins.
New collagen and elastin form over about 12 weeks, when the main lift becomes visible.
Results peak around 3 months and typically hold for the rest of roughly 12 months.
A maintenance session, often around 1 year later, refreshes the lift 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 laxity, maps target zones and explains the expected timeline and longevity.
After cleansing, the doctor delivers the planned passes with surface cooling; a session takes around 30 to 45 minutes.
Most patients have a single session, which suits a short Seoul trip; any maintenance is timed separately.
Some firmness shows early, with the main lift building over about 12 weeks as collagen and elastin form.
Results typically last around a year; SPF, good skincare and a yearly maintenance session help sustain them.



Sofwave results typically last around a year, building over about 12 weeks as new collagen and elastin form. Longevity varies with age, skin laxity and lifestyle, so it is a realistic range rather than a fixed figure. Your expected timeline is individualized when you discuss Sofwave with the team.
Some firmness can appear within the first few weeks, but the main lift builds over about 12 weeks as collagen and elastin form, peaking around three months. Patience is part of the treatment. The expected timeline for your face is mapped during the Sofwave assessment so expectations stay realistic.
No, Sofwave is not a one-time fix; it refreshes your skin’s collagen structure, which then ages naturally alongside you. Results typically last around a year before a maintenance session is considered. Because the effect comes from your own tissue, longevity is individual and is discussed honestly during your consultation rather than promised as forever.
Age, baseline skin laxity, sun exposure, smoking and weight changes all influence longevity, since they affect how well your new collagen is maintained. Younger, less lax skin often holds results longer. Daily SPF and good skincare help, and your doctor explains how these factors apply to your skin at consultation.
Many patients have a maintenance session around once a year, timed to refresh the lift as natural aging continues, though the interval is individual. Repeating too soon is usually unnecessary. Your doctor advises on timing during follow-up so maintenance matches your skin response rather than a fixed calendar for everyone.
Most patients achieve their result with a single session, which is convenient for travelers, with an optional maintenance treatment later. Stacking multiple sessions up front is not usually needed for longevity. Because one session is typical, the plan and follow-up timing are confirmed after your assessment with the clinic’s doctors.
All three typically last around a year, though deeper devices may hold slightly longer for advanced laxity. They differ in energy type and depth rather than dramatically in longevity. Compare Ultherapy Prime and Thermage FLX with the team to match durability to your goals.
No, Sofwave results do not vanish overnight; the lift gradually softens over months as natural aging continues, rather than reversing abruptly. This is why a maintenance session is timed before the effect fully fades. Your doctor helps you recognize when a refresh is appropriate so the improvement is sustained smoothly.
Daily sun protection, a consistent skincare routine, stable weight and avoiding smoking all help preserve the new collagen, extending your result. A well-timed maintenance session supports longevity too. Some patients combine skin-quality treatments such as Rejuran Healer when their doctor advises, to support overall skin condition.
Sofwave produces measurable, lasting collagen change across skin types, and a Korean histology study supports its effect on Asian skin specifically. Longevity still depends mainly on individual factors like age and laxity rather than ethnicity. Your expected duration is assessed individually before any plan is finalized by the clinic’s doctors at consultation.
For many patients, a comfortable, no-downtime treatment that holds for around a year is a practical way to maintain firmer skin over time, especially with yearly maintenance. Value depends on your goals and expectations, which the team discusses honestly at consultation so you can weigh longevity against alternatives before deciding.
Yes, because most patients have a single session lasting around 30 to 45 minutes, maintenance fits easily into a future Seoul visit roughly a year later. Reberry Clinic serves international patients with English-speaking support across three Seoul-area locations, so you can schedule a refresh around your travel itinerary when results begin to soften.
Yes, most patients fly the same or next day, since downtime is minimal, and the main lift develops gradually over about 12 weeks after you return home. You receive a written aftercare plan so you can support and follow up on your Sofwave results from abroad with the team.
Most patients feel warmth and brief pulses rather than significant pain, eased by the integrated surface cooling, and a typical session lasts around 30 to 45 minutes. Comfort and timing depend on the area and passes. Both are explained at consultation so you can plan a single visit around a short Seoul trip.
Downtime is minimal; mild redness or slight swelling can occur but usually settles within hours to a day, while the lift itself develops gradually over about 12 weeks afterward. So there is no recovery period blocking your plans, yet the visible result builds patiently over the following weeks as collagen forms.
Because most patients have a single session lasting around 30 to 45 minutes, even a short trip works, with no required multi-day course. The result then develops after you travel home. Our team helps you schedule the visit around your itinerary so the treatment fits comfortably into your time in Seoul.
