What is Thermage FLX?
Thermage FLX delivers monopolar radiofrequency energy through a single-use treatment tip. The energy heats the deeper dermis and the fibrous layers beneath it, while vibration and cooling protect the surface. This heat contracts existing collagen and triggers new collagen production over the next few months, so the skin becomes firmer and smoother.
Compared with earlier Thermage generations, FLX uses a larger tip that covers more area per pulse and an energy feedback system that helps keep heat delivery even, which can shorten treatment time. It is suitable for the face, jawline, eyelids and neck.

Who is a good candidate for Thermage FLX?
- Early to moderate sagging of the cheeks and jawline
- Loss of firmness and fine lines
- Loose skin on the eyelids or neck
- People in their 30s to 60s seeking gradual, natural results
- Anyone who cannot take downtime
Thermage FLX is not suitable during pregnancy or for people with a pacemaker or implanted electronic device. Very heavy laxity may need a different approach. Tell the doctor about fillers, threads, metal implants or skin conditions so the plan can be adjusted.

Before & after at Egg Clinic

How many Thermage FLX shots do I need?
The shot count reflects how much area is treated and how many passes are made. As a general guide, 300 shots suit a smaller area or a lighter treatment of the lower face, 600 shots cover the full face more thoroughly, and 900 shots allow the face plus jawline and neck or extra passes on lax areas. The eyelids use a dedicated eye tip with its own shot counts. The doctor recommends the count after assessing your skin, and you can compare options on the Thermage price list.
