DetailsThermage FLX Skin Tightening
Thermage FLX uses radiofrequency heat energy to smooth and firm the skin's surface and dermis, and is one of the strongest non-surgical skin-tightening treatments available. An evolution of the earlier third-generation device, Thermage FLX is recommended for anyone who wants a simple, non-surgical way to improve elasticity, tightening, lifting, and fine lines. It also features an automated algorithm that controls the timing and amount of energy delivered, so each treatment area gets the right amount of energy for its skin thickness.

Thermage FLX
Effects & advantages
Key features of Thermage FLX
- 01
Firmer, tighter skin
Radiofrequency heat regenerates collagen deep in the skin, which improves elasticity and tightening.
- 02
Smoother fine lines
Collagen fibers contract and new collagen forms, which smooths wrinkles around the eyes and face.
- 03
30 minute session
Faster treatment
An upgraded tip delivers treatment twice as fast as before. The procedure takes about 30 minutes.
- 04
Right energy per area
An automated algorithm controls the timing and amount of energy, matched to each area's skin thickness.

Results after Thermage FLX
By cooling the surface while heating the dermis, Thermage FLX delivers radiofrequency energy that causes collagen fibers to denature and contract, regenerating collagen and smoothing wrinkles. This firms sagging cheeks, jowls, eyelid skin, and neck wrinkles, and is also effective for a drooping forehead or eyelids, sagging cheeks, jaw, or neck, crepey skin on the abdomen, and recurring acne or acne scars. Because it takes time for collagen to regenerate, elasticity continues to improve gradually, with lifting results lasting around a year and continuing to develop over time.
How it helps
Sagging cheeks & jowls
Firms sagging cheeks and jowls, and a drooping jaw or neck.
The principle, in plain words
How does Thermage FLX work?
Thermage FLX cools the surface of your skin while heating the dermis with radiofrequency. The heat makes collagen contract, and your skin then builds new collagen.
Thermage FLX uses radiofrequency current to cause tissue coagulation, treating fine lines around the eyes and face non-invasively. By cooling the skin's surface while generating heat in the dermis, it delivers radiofrequency energy efficiently, causing collagen fibers to denature and contract — effectively regenerating collagen and smoothing wrinkles.
