Short answer: Thermage FLX tightens skin with monopolar radiofrequency in one 45–90 minute session, with no downtime. A full face typically uses about 600 shots. Some firming is visible immediately, and the main result develops over 2–6 months and lasts 1–2 years.

1. What it feels like

Each shot gives a brief deep warmth, followed by cooling and vibration. Topical numbing helps, and energy is adjusted area by area.

2. Shots and areas

Face-only treatments often use 600 shots; adding eyes or neck may take 900 or more. The single-use tip counts shots, so you can see the number. See how many shots do I need?

3. Thermage or Ultherapy?

Thermage tightens skin texture; Ultherapy lifts deeper tissue. Many patients do both on the same day. Compare them.

4. Before your appointment

  • Remove metal jewellery
  • Tell the doctor about pacemakers or implanted devices
  • Arrive without makeup if possible

5. After treatment

Makeup is fine the same day. Avoid saunas for 24–48 hours and use SPF daily. You can fly the next day.

Conclusion

Thermage FLX is one of the simplest high-value treatments to fit into a Seoul trip. Custom Thermage at The Heal.
