What is Thermage FLX?

Thermage FLX is the fourth-generation Thermage system from Solta Medical. It uses monopolar radiofrequency to heat the deeper layers of the skin in a controlled way. That heat makes existing collagen fibers contract straight away and signals the skin to build new collagen over the following months. The result is firmer, smoother, more lifted-looking skin without incisions, needles or recovery time.

In Korea, Thermage is one of the most requested non-surgical lifting treatments because it suits busy schedules: one session, no bandages and no visible wounds. That makes it a practical choice for international visitors who want a meaningful change during a short stay in Seoul.

How Thermage FLX works

Each pulse delivers RF energy through a single-use treatment tip. The FLX system's AccuREP technology measures your skin before every pulse and tunes the energy so heating stays even across the face. At the same time, the tip cools the surface with cryogen spray and vibrates gently, which protects the outer skin and makes the heat more comfortable.

  • Immediate effect: collagen fibers tighten, so many patients see a subtle firming the same day.
  • Long-term effect: new collagen forms over 2–6 months, which is when the real change appears.
  • Eye tip: a smaller tip treats the upper and lower eyelids to soften hooding and crepey texture.

Who is a good candidate?

  • Adults, typically from their early 30s, with mild to moderate loss of firmness
  • Early jowls, a softening jawline or loose skin under the chin
  • Crepey or thinning skin on the eyelids, cheeks or neck
  • People who want natural-looking tightening with no downtime

Thermage is not a substitute for a surgical facelift. If sagging is advanced, your doctor will explain honestly what RF can and cannot do, and may suggest combining it with Ulthera Prime or a thread lift.

Treatment areas and shot counts

Plan Typical areas Notes
300 shots Face (focused) Good first treatment or maintenance
600 shots Full face and jawline The most popular plan for visible tightening
900 shots Full face, jawline and neck For laxity that extends to the neck
Eye tip Upper and lower eyelids Often added to a face plan

Your doctor confirms the shot count after examining your skin. See current plans on the Thermage FLX price page.

Your session at Dernia, step by step

  1. Consultation in English — your doctor examines skin thickness and laxity and agrees a shot plan with you.
  2. Cleansing and numbing — topical anesthetic for about 30–40 minutes.
  3. Grid marking — a temporary grid guides even coverage.
  4. Treatment — passes over each area; energy is adjusted to your comfort.
  5. Soothing — a calming mask or LDM to settle any redness.

You can ask to see the sealed, genuine tip opened before treatment and the shot counter at the end — a good habit at any clinic.

Downtime and aftercare

Most people leave with slight pinkness that fades within a few hours. You can usually wear makeup the same day and continue sightseeing. For the first day, skip saunas and very hot baths, keep the skin hydrated and use sunscreen. Rare effects such as temporary tenderness or small blisters are managed by the medical team. Read the full guide to normal side effects.

Results: what to expect and when

Some firming is visible straight away, but the main change develops gradually as new collagen forms. Most patients notice smoother texture and a tighter jawline at around one month, with the best result at three to six months. Many repeat Thermage every 12–18 months to maintain it. See the detailed Thermage FLX results timeline.

Thermage FLX vs other lifting treatments

Thermage tightens the skin itself, while ultrasound lifting such as Ulthera targets the deeper SMAS layer that supports the face. That is why the two are often combined. Korean RF devices like Oligio X and Volnewmer work on a similar principle at a lower price. Compare them side by side: Thermage vs Ulthera, Thermage vs Oligio X and Thermage vs Volnewmer.

Planning Thermage FLX around a trip to Seoul

Because it is a single session with no recovery period, Thermage fits easily into a short visit. Book it early in your stay so the doctor can check your skin before you fly. You can fly the next day. If you also want injectables such as Botox or skin boosters, your doctor will advise the best order — see combining treatments in one visit.

Safety: who should avoid or delay it

Thermage is not suitable if you have a pacemaker or another implanted electronic device, are pregnant, or have an active skin infection in the area. Tell your doctor about recent fillers, threads, metal implants or skin conditions. Thermage FLX is FDA-cleared for the non-invasive treatment of wrinkles, including the eyelids, and is performed at Dernia by licensed medical doctors. Book a consultation to check whether it suits you.

Does Thermage FLX hurt?

You will feel short pulses of deep heat, balanced by cooling and vibration. Numbing cream is applied first and energy is adjusted to your comfort, so most people describe it as very warm rather than painful. Bony areas such as the jawline feel hottest.

How many shots do I need?

300 shots suits a focused face treatment or maintenance, 600 shots covers the full face and jawline, and 900 shots adds the neck. Your doctor recommends a count after assessing your skin.

Can I fly after Thermage?

How long do Thermage results last?

Results develop over 2–6 months and commonly last around 12–18 months, depending on your age, skin quality and lifestyle.

Can I combine Thermage with Ulthera or Botox?

Yes. Ulthera and Thermage are often combined in one visit because they work at different depths. Botox and skin boosters can usually be added the same day; your doctor will confirm the order.

Is Thermage worth it compared with Korean RF devices?

Thermage FLX is the original monopolar RF system with the longest track record; Korean devices offer a similar principle at a lower cost. Read our honest Thermage FLX review to decide.
