What is Thermage FLX Body?
Thermage FLX Body uses patented monopolar radiofrequency technology to heat the deep collagen-rich layers of the skin, tightening existing fibres and stimulating the production of new ones. It is a single-session, non-invasive treatment with no anaesthetic, no incisions and no meaningful recovery time.
The Body tip is specifically designed for larger surface areas. It can be used on the arms, abdomen, thighs, buttocks, knees and other areas where skin laxity or softness is a concern. Results continue to develop for several months as new collagen is produced, and are backed by over fifty published clinical studies.
Thermage FLX integrates Comfort Pulse Technology with AccuREP technology, which auto-tunes each energy pulse for consistent delivery throughout the session. This means the treatment is comfortable and precise, with the energy depth calibrated to reach the collagen layer without damaging the surface of the skin.

What to expect from Thermage FLX Body
- Step 1
Consultation
Your practitioner assesses the areas of concern, discusses your goals and confirms Thermage FLX Body is the right treatment for you.
- Step 2
Treatment
A conductive coupling fluid is applied and the Thermage handpiece is moved across the treatment area in a systematic pattern. Most patients find the session comfortable, with a warm sensation during each pulse.
- Step 3
Results
Some firming is noticeable immediately. The main improvement develops progressively over the following months as new collagen is produced, with results typically continuing for up to six months.
There is no recovery period. The treated area may look pink and feel warm or slightly tender for a few hours, and mild swelling is occasionally noticeable on the first day; both settle by themselves. You can dress normally and return to all your usual activities, including exercise, straight away. Keep skincare gentle for the first 24 hours, avoid very hot baths, saunas and steam rooms on the day, and use a daily broad-spectrum SPF on any area that will be exposed. The key point is timing: any immediate tightening is a bonus, and the meaningful change comes from new collagen forming over the following months, so the result is best judged at around six months rather than in the first few weeks. Contact the clinic if you notice blistering, an area of unusual firmness, or any change in the contour of the treated area.

Frequently asked questions about Thermage FLX Body
Which body areas can Thermage FLX treat?
The Body tip is used on the arms, abdomen, thighs, buttocks, knees and love handle area. It is particularly popular for post-pregnancy tummies, inner arms and thighs where skin has loosened over time.
How many sessions are needed?
Thermage FLX Body is designed as a single-session treatment. The collagen remodelling that follows continues to improve the result for months afterwards. A repeat session can be considered after a year or two to maintain the benefit.
Is it painful?
Thermage FLX integrates Comfort Pulse Technology to make the session as comfortable as possible. Most patients experience a warm, deep heating sensation but find the treatment tolerable throughout.
When will I see results?
Some tightening is visible straight after treatment. Results continue to develop as new collagen forms, with the most noticeable improvement typically at the three to six month mark.
Is there any downtime?
No. Thermage FLX is a non-invasive treatment with no recovery period. Patients can return to normal activities, including exercise, immediately after their session.
How much does Thermage FLX Body cost?
Pricing depends on the areas treated and what is agreed for you and is confirmed in writing at your consultation, with no obligation to proceed.
