Thermage in Korea: Downtime, Results Timeline and Trip Planning

Researched by the Clinic KR editorial team. Sources checked October 9, 2026. Not reviewed by a physician: use it to prepare questions for your surgeon.

Short answer: most people have one Thermage treatment and feel some tightening right away, with the best results at about six months (American Academy of Dermatology). In a study of more than 600 treatments, redness and swelling usually lasted less than 24 hours, and a few people had swelling for up to a week (Weiss et al., 2006). There is no surgical wound, so one session fits into a short trip.

Thermage recovery and results timeline First week: one session, some tightening felt right away, redness and swelling usually under 24 hours, occasionally swelling up to a week. Results: improvement at 1, 3 and 6 months in a study of Asian patients, best results at about 6 months. Thermage recovery and results timeline Sources: AAD and studies.

What Thermage is, and what the FDA cleared

Thermage delivers monopolar radiofrequency energy through a cooled tip to heat the deeper skin and encourage tightening. Thermage FLX was FDA cleared in September 2017 (K170758) for non-invasive treatment of wrinkles, including those around the eyes and on the upper and lower eyelids. Thermage CPT, the previous generation, is still used in some clinics. Ask which one you are getting and how many shots.

What the studies show

  • Side effects: in more than 600 treatments, redness and swelling usually lasted under 24 hours, six people had swelling for up to a week, and 2.7 percent had any temporary side effect, with none permanent (Weiss et al., 2006).
  • Asian patients: 30 patients with skin types III to V improved at one, three and six months after a single session, with an average pain score of 3.1 out of 10 and no serious side effects (Wanitphakdeedecha et al., 2022).
  • Technique matters: in a survey covering 5,700 treatments, the newer multiple-pass method gave tightening at six months in 92 percent, against 54 percent with the old single-pass method (Dover and Zelickson, 2007).
  • Burns: a 2003 study of the first-generation device found small burns in 0.36 percent of applications. Current devices and techniques differ, so this figure is historical (Fitzpatrick et al., 2003).

How long to stay in Korea

The British Association of Aesthetic Plastic Surgeons (BAAPS) groups procedures for people who travel abroad. Treatments done under local anaesthetic in under 90 minutes are in its lowest group, with no extra time in the destination country needed for travel reasons. The NHS advice about waiting before flying is written for surgery, not for treatments like this one.

So what decides the length of your stay is the treatment itself: only comfort and timing. Most people return to normal activities the same day. Results build over months, so plan before photos in Korea and compare at home.

A sample 3 to 5-day plan

Days Plan
Day 1 Arrive. Consultation and before photos.
Day 2 Thermage session.
Days 3 to 5 Normal sightseeing with sunscreen, then fly home.

Replace every date with the ones your clinic gives you. The Clinic KR trip planner lays them out day by day and flags a flight that is booked too early.

Questions to ask your clinic before you book flights

  1. Is this Thermage FLX or CPT, and how many shots will you use?
  2. Can I see the sealed tip being opened?
  3. Which areas will you treat, including the eyes?
  4. What should I do if I see a blister or a dent after I am home?
