Mariela August 11, 2025

A doctor or therapist checks your skin. Thermage FLX (熱瑪吉) may be the perfect treatment for you. Your face or treatment area is cleaned. A grid is placed on your skin to guide the machine. The Thermage handpiece is moved over the area.

It is one of the most popular non-invasive skin tightening treatments in Hong Kong and around the world. It is safe, fast, and effective.

In this article, you will learn all the basic facts about Thermage FLX in a very easy and simple way.

What Is Thermage FLX?

Thermage 熱瑪吉 is a non-surgical skin tightening treatment that uses radiofrequency (RF) energy. It heats the deep layers of the skin to:

  • Tighten loose skin
  • Smooth fine lines and wrinkles
  • Boost collagen production

The treatment is FDA-cleared and very safe when performed by trained professionals.

You don’t need to worry about pain or long recovery. You can go back to work or your daily life right after the treatment.

What Is Collagen?

Many people do the treatment once a year to maintain the effect. RETENS uses the latest Thermage FLX machines, which are more comfortable and effective than older versions.

As we get older, the body makes less collagen. This is why we get:

  • Wrinkles
  • Loose skin
  • Sagging

Thermage FLX helps your body make new collagen, so your skin becomes firmer and younger again.

What Areas Can Thermage FLX Treat?

Thermage FLX can be used on many parts of the body:

  • Face – smooths wrinkles and tightens the jawline
  • Eyes – reduces sagging eyelids and under-eye wrinkles
  • Neck – firms loose skin
  • Arms and thighs – reduces flabbiness
  • Stomach – tightens post-pregnancy or aging skin

It’s a full-body lifting solution, not just for the face!

How Does Thermage Work?

  • The Thermage machine sends radiofrequency energy deep into your skin.
  • This warms the collagen-rich layers and causes them to contract.
  • At the same time, it starts new collagen growth.

Thermage is a good middle choice for those who want results but without pain or surgery. Why Choose RETENS for Thermage FLX? RETENS is a trusted clinic in Hong Kong. Here’s why many clients choose RETENS:
