Quick answer

What is Thermage?

Thermage FLX is a non-invasive monopolar radiofrequency (RF) treatment that heats the deep dermis to tighten existing collagen and stimulate new collagen. It firms mild sagging on the face, jawline, eyes and neck without injections, incisions or downtime.

What Thermage treats

Thermage FLX in Seoul for a soft, natural look

Thermage works best when the skin has started to loosen but hasn't dropped significantly. It tightens the skin you already have rather than adding volume or changing facial shape, which is why it suits patients who want to look rested, not altered.

  • Early to moderate skin laxity
  • Soft jawline and jowls
  • Drooping cheeks and nasolabial folds
  • Upper and lower eyelid crepiness
  • Fine lines and uneven texture
  • Mild neck sagging

For deeper sagging, your doctor may pair Thermage with Ultherapy, which lifts the deeper SMAS layer, or with a thread lift for mechanical support.

How Thermage works

A treatment tip delivers radiofrequency energy into the dermis while cooling the skin surface. The controlled heat does two things. It contracts existing collagen, so some patients notice slight tightening the same day, and it triggers new collagen production, which continues for months.

Because RF energy heats tissue evenly across a wide area, Thermage is strong on overall skin quality and firmness. Focused ultrasound devices such as HIFU work at fixed depths in small points, which is why the two are often combined.

Your treatment day

  1. Consultation and skin analysis Your doctor assesses laxity and skin thickness, with Mark-Vu II imaging where useful, and sets the areas and energy plan.
  2. Cleansing and grid marking A temporary grid guides even coverage so no area is over- or under-treated.
  3. RF treatment Pulses are delivered with continuous cooling. Expect brief warmth or a snapping sensation. Full face takes about 45–90 minutes.
  4. Recovery in your private room Mild redness usually settles within hours. You can apply make-up and return to your plans the same day.

Results timeline

Thermage results are gradual by design. Most of the change comes from new collagen, which takes weeks to form.

Same day Slight firming from collagen contraction
2–4 weeks Skin feels smoother and more elastic
8–12 weeks Visible tightening as new collagen forms
12–18 months Typical point to repeat for maintenance

Thermage FAQ

Does Thermage hurt?

Most patients feel short bursts of heat or a snapping sensation with each pulse. The device cools the skin throughout, and your doctor adjusts energy to your comfort. A topical numbing cream is usually applied first.

How long do Thermage results last?

Typically 12–18 months. Results continue to improve for about 3 months after treatment as new collagen forms. Age, sun exposure and skin condition affect how long they last.

How many sessions do I need?

One session is usually enough for a visible result. Most patients repeat every 12–18 months for maintenance.

Can I fly home right after Thermage?

Yes. There is no downtime, so Thermage fits a short trip to Seoul. Mild redness typically fades within a few hours. We can schedule your appointment around your travel dates.

Thermage or Ultherapy: which is better?

They treat different layers. Thermage tightens the skin itself through RF heating of the dermis. Ultherapy uses focused ultrasound to lift deeper tissue. For sagging with crepey skin, many patients combine both.

Can Thermage be combined with Botox or fillers?

Yes. Botox and contouring fillers are often planned alongside Thermage. Your doctor will advise on order and timing.

Is the Thermage at DIORE genuine?

Yes. DIORE uses genuine Thermage FLX equipment and authentic, verified treatment tips. You can ask to see the tip before your treatment starts.
