Does ThermiSmooth shrink the fat underneath facial skin?

Doctor Answers 5


Hi Noor! I would check to see which version of the Thermi device your physician has. The Thermi250 has different hand pieces that allow the radiofrequency energy to travel different depths of the skin. The smaller spot sizes are great for skin laxity treatment. The radiofrequency energy stimulates collagen repair and regeneration, which help to tighten the skin. The larger spot sizes penetrate more deeply to heat and reduce fat cells.

I hope this helps!

ThermiSmooth can tighten skin but will not lessen fat

ThermiSmooth is external radiofrequency energy designed to tighten skin. It can't reduce fat volume as it does not penetrate deeply enough nor does it heat enough to melt or kill fat cells.

Please keep in mind this is not a diet/weight loss procedure. The results differ from one person to the next. Thermismooth assists with improving the appearance of aging skin through tightening of the skin and collagen production.  The collagen underneath the skin is heated to a certain temp and maintained at that temp for about 7 to 10 minutes in that specific area. There are some who see some residual fat loss, but again each individual will notice different results. It is always best to seek consultation from a Reputable physician so that he/she can assess your concerns. Go over any and all questions you may have. And Can with the up most confidence go over all your options. This way you can make the best Informed decision for the results you are seeking.

Thermi Smooth and fat

Good question!  Thermi Smooth alone does not shrink fat.  The Thermi 250, however, has the ability to shrink fat.  It is all a matter of understanding the physics of the machine.  Thermi 250 has 10 times the power of the Thermi Smooth and depending on what hand piece the physician chooses, you can target different depths beneath the skin (ie targeting skin/dermis for skin tightening, superficial fat for cellulite or deeper fat layers). That's why it is so important to have a face to face consultation and exam with a Board Certified plastic surgeon who understands and has the tools to potentially treat unwanted fat either invasively (liposuction), minimally invasively (Thermi Tight), or non invasively ( Thermi 250, CoolSculpt, etc). That way you have a unique treatment plan developed specifically for your own body issues.

ThermiSmooth and Fat

Thank you for a great question.  Unfortunately, there is not a cut-and-dry answer to this one, since there are no studies I am aware of to address this.  I rely on ThermiSmooth and their new device Thermi250 for many applications in my office.  For patients who are concerned about the theoretical risk of loss of facial fat, I ONLY use the smallest head or the bipolar attachment, as I know those heads will not penetrate deeper than the skin or dermis.  The larger the diameter of the head, the deeper the penetration into tissue and the larger heads do cause some shrinkage of the fatty layer.  To date, I have not had a patient lose facial fat volume as a result of using the more superficial ThermiSmooth or Thermi250 treatments, so my gut feeling is that you should experience facial fat reduction if the smallest head or the bipolar head are used, but, again, this is not based on a formal study, but only my own clinical experience.
