A visit-planning guide to Sofwave at RESUM Plastic Surgery Clinic in Gangnam, Seoul: how much time to set aside, what the first days look like and when the result shows.

Sofwave is a non-surgical ultrasound treatment that heats the mid-dermis, about 1.5 mm below the skin surface. Every shot sends 7 parallel beams (the technology is called SUPERB), and the heat prompts the skin to make new collagen and elastin. The aim is firmer skin, a more even texture and softer fine lines.
The outer skin and the fat layer underneath are left alone. Sofcool cooling keeps the surface cool for the whole session, which is why numbing cream is usually enough. It is also why people with thin skin or a lean face, who worry about hollow cheeks, can often consider it.
Set aside about 30-45 minutes for the session itself, plus the consultation and the wait while numbing cream takes effect. Nothing needs to be blocked off afterwards, because you can carry on with your day as soon as you leave. Tell us your travel dates in advance so the consultation and the session can be arranged on the same visit where possible.
| Session | About 30-45 minutes |
|---|---|
| Numbing | Numbing cream |
| Back to daily activities | Right after the session |
| How long it lasts | About 12 months |
Sofwave does not lift at the depth of the SMAS. It works in the 1.5 mm layer only, so pronounced sagging, or a jawline that needs contour lifting, is outside its range. In that case Dr. Jin-Young Kim will say so in the consultation and explain Ultherapy or facelift surgery, and whether Sofwave can be added to them.




Your main concerns are texture, fine lines, pores or skin that has lost firmness, not deep sagging.
Your face is lean or your skin is thin, and you do not want to lose volume in the cheeks.
You want a session that needs numbing cream only and leaves little visible downtime.
You have had, or are planning, Thermage or Ultherapy and want the dermis treated as well.
You expect to come back for a touch-up every 6 months to 1 year.
Slight redness and mild swelling for 1-2 days are the usual reaction. They fade without treatment, and makeup covers them in most cases.
For 1 week, stay away from saunas, jjimjilbang and other strong heat or irritation. Be careful with sun protection during the 4-12 weeks in which new collagen and elastin are forming.
The first tightening is felt right after the session. The result then improves over 4-12 weeks and settles gradually over 2-3 months, so most of the change appears after you have returned home.
Sofwave is not recommended during pregnancy, and it is not used on skin with an active infection or severe inflammation.
Burns, hyperpigmentation and cheek hollowing are the risks named for this kind of treatment. Because only the mid-dermis is heated and the surface is cooled, the risk tends to be low, and the intensity is still chosen after your skin thickness and fat distribution have been assessed.
The number of shots and the result differ from person to person. Please consult Dr. Jin-Young Kim before treatment.
Yes, a short stay is usually enough, because a Sofwave session takes about 30-45 minutes and daily activities resume right after. Allow for slight redness or swelling for 1-2 days, and keep away from saunas for 1 week.
Discomfort with Sofwave tends to be low, and numbing cream is normally all that is used. Sofcool cooling chills the skin surface throughout the session, so IV sedation is not needed.
Sofwave uses ultrasound at about 1.5 mm, in the mid-dermis. Thermage also targets the dermis but with radiofrequency (RF), and Ultherapy works deeper, at the SMAS. Which one fits depends on whether texture and firmness or deeper sagging is the priority.
Yes, Sofwave is sometimes used alongside Thermage or Ultherapy, because each differs in energy type or in the layer it reaches. Whether they can be done together in your case is assessed by the doctor in the consultation.
The result of Sofwave lasts about 12 months. People who want to keep it steady return on a touch-up cycle of 6 months to 1 year, and Dr. Jin-Young Kim sets the shots and the intensity each time.
