Treatment room prepared for Thermage FLX body treatment at Umi Clinic, Myeongdong — **1 session** Tightening builds over 2–6 months

Quick answer

What is Thermage FLX for the body?

Thermage FLX is a monopolar radiofrequency (RF) device from Solta Medical. On the body it uses a larger treatment tip to heat the deep dermis and fibrous septae evenly, tightening collagen and stimulating new collagen while a cooling spray protects the surface.

It is usually a single session for loose skin on the abdomen after pregnancy, the upper arms, inner thighs or above the knees. It is the same platform as Thermage FLX for the face, with body-specific tips and shot counts.

How Thermage FLX body works at Umi

Every visit is doctor-led and explained in English, from the first skin check to aftercare.

Consult & area planning
The doctor checks laxity and skin thickness, then agrees areas and shot count with you.
Grid marking
A temporary grid is applied so every square receives even passes.
RF with cooling
Each pulse heats deeply with a cooling spray before and after; energy is matched to your comfort feedback.
Aftercare
Mild redness settles within hours. Normal showering and activity the same day.

Before & after

How Thermage FLX tightens body skin

Deep, even RF heat contracts collagen immediately and then stimulates new collagen, so the skin keeps firming for months.

FAQ

Thermage FLX body questions

How many sessions does Thermage FLX body need?

Usually one session. Some people choose a repeat treatment after 1–2 years.

Is Thermage FLX body painful?

You feel short bursts of deep heat with each pulse. Cooling and adjustable energy keep it tolerable, and most people do not need numbing.

How is it different from Onda?

Thermage FLX uses monopolar RF to tighten skin. Onda uses microwave energy that targets fat as well as tightening, so the choice depends on whether looseness or fat is your main concern.

Can I treat several areas in one visit?

Yes, if the shot count allows. The doctor will plan the order so the session stays comfortable.

Do foreigners pay more?

No. International patients pay the same price as local patients at Umi Clinic.
