Thermage FLX®
Non-surgical Skin Tightening & Firming
What is Thermage FLX?
Thermage FLX® is a non-invasive skin tightening treatment that uses monopolar radiofrequency (RF) energy to stimulate your skin’s natural collagen production. By delivering controlled heat deep into the dermis while protecting the skin surface, Thermage FLX helps improve skin firmness, texture, and contours — without surgery, injections or downtime.
This latest generation of Thermage technology offers enhanced comfort, precision, and consistency, making it a popular choice for patients seeking natural, gradual rejuvenation.
How Thermage FLX Works
Thermage FLX works by gently heating the deeper layers of the skin where collagen lives.
- Controlled RF energy is deliverred to trageted depths
- Existing collagen fibres contract, giving an immediate tightening effect
- New collagen production is stimulated, leading to progressive firming over time
An integrated cooling system and vibration technology improves comfort while ensuring the skin surface remains protected throughout treatment.
What Can Thermage FLX Treat?
Thermage FLX is versatile and can be used on both the face and body, including:
- Face: cheeks, jawline, nasolabial folds, lower face sagging
- Eyes: upper and lower eyelids, crow’s feet
- Neck & décolletage
- Body: Abdomen, arms, thighs, knees
- Mild skin laxity and crepey skin
It is particularly suitable for patient with mild to moderate skin laxity who are not ready for surgical procedures.
Thermage FLX FAQ
For most patients, only 1 session of Thermage FLX is needed to achieve visible skin tightening and firming.
This is one of the key advantages of Thermage FLX—it is designed as a single-session treatment rather than a series of repeated visits.
Thermage FLX is generally well-tolerated, and most patients find the experience bearable—but comfort levels can vary based on individual sensitivity and the area being treated.
What You’ll Feel During Treatment
Thermage FLX uses advanced cooling, vibration, and controlled radiofrequency energy to make the procedure more comfortable. Typical sensations include:
-
Cool pulses on the skin surface
-
Deep warming or heat sensation under the skin
-
Mild vibrational pressure
Some patients describe the feeling as a warm, tapping sensation — similar to a deep heat massage.
Thermage FLX has little to no downtime.
Most patients are able to return to normal daily activities immediately after treatment.
