What is Thermage FLX?

Thermage FLX is a monopolar radiofrequency device that heats the deeper layers of the skin evenly to tighten and smooth it.

How it works

Radiofrequency energy heats collagen in the dermis while the tip cools the surface. The FLX system reads skin response with each pulse and adjusts delivery so the heating stays consistent across the treated area.

Who it may suit

It is often considered for:

What it does not do

It is not designed to remove fat or fill hollows, and the effect on deep jowls may be limited when sagging is advanced.

Before your consultation

  • Metal implants or pacemakers
  • Previous RF treatments
  • Areas around the eyes you want included
  • Medicines you take, pregnancy or breastfeeding
