ThermiTight / ThermiRF

ThermiTight is a procedure done with the ThermiRF machine.  ThermiRF describes the technology of using heat and radiofrequency to perform non-surgical tightening and dissolving of fat.  ThermiTight uses a microcannula to go under the skin of the area being treated and heats the area with radiofrequency to a temperature that will cause tightening and lipolysis (bursting fat cells).  The outside skin of the area being treated is monitored with an infrared skin thermometer to minimize the chance of injuring the skin and / or causing a burn.  The procedure is done while the patient is awake and the downtime is very minimal (a couple of days of swelling if no liposuction is done at the same time) with some possibility for minor bruising.  Results are usually first noticed a few weeks after the procedure but then continue to improve over the course of the next several months--improvement has even been seen to continue after one year!  This is an exciting technology and the first time we have truly had something "non-surgical" that is worthwhile to provide long lasting results.

ThermiAesthetics, the company, has developed a platform to deliver radio-frequency energy that is able to tighten skin, stimulate collagen, melt fat, ablate nerves, each at a specific set temperature.  As mentioned below, the various procedures refer to the delivery techniques used.  ThermiTight is usually applied as a single treatment and is micro-invasive, in the sense that a cannula is inserted by the doctor,  below the skin surface so we are able to melt fat, tighten the sub-cutaneous tissue and the also tighten skin.  Therefore it produces more lift and shaping than Thermismooth, which is a topical application and better for improvement of fine lines around the eyes and mouth and can be performed by a skilled laser technician.    I use ThermiTight  in both the lower and upper face, if needed, to raise the brow and tighten upper face skin, although the classic area of treatment is for the lower face and neck, where we have the most experience.  Thermi Raise and ThermiDry are also applications (the first as an alternative to botulium toxin injections and the second to treat excessive sweating).  There is several days of swelling after ThermiTight (so we often perform it on a Thursday or Friday for patients who want to get back to work on Monday) while there is no down time with Thermismooth (but typically 3-4 treatments are needed to get the desired improvement).  I've been very impressed with the technology both as far as safety and effectiveness but it takes several months until you see the results because it works by stimulating the body's own collagen and contracting the tissue under the skin to create the "lift".  While we offer Ulthera as well as many other device technologies in our practice, ThermiTight has been the most impressive (other than surgery) as far as delivering surgery like results, without the downtime, expense and potential risks of surgery.  Results are technique dependent so it's important to find a doctor well versed with this technology for optimal results and not everyone is an ideal candidate for these treatments.  Sometimes it's best to combine this treatment with Sculptra or filler for the ideal result in the face.  In the body, we often will use it to tighten skin after Coolsculpt or other fat reduction treatments.

I hope that helps and best of luck!

ThermiTight and ThermiRF

Thank you for your question.  ThermiRF is the radiofrequency technology that ThermiTight is based on. It's considered a micro invasive procedure where a small cannulas is placed under the skin to tighten the skin and the tissues underneath for a lift. Same device, a non invasive procedure is ThermiSmooth without any downtime.

ThermiTight vs ThermiRF

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}
It is the same, ThermiRF is the old name. Now there is ThermiTight for the internal treatment and ThermiSmooth for  the external treatment, it's easier to describe for the company.

ThermiRF vs ThermiTIGHT

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

ThermiRF is the company and platform for all THERMI procedures that include ThermiTIGHT, ThermiSMOOTH, ThermiVA, and Thermi250.  They all use radiofrequency to tighten or remove fat.  ThermiTIGHT is minimally invasive (goes under the skin thru small needle holes) while the others are non invasive and are only applied to the skin.  I have all of these platforms and they all work great in the right hands - i.e. they are all user dependent!  Each does something a bit different and is best for different areas.  Ask your Thermi doc to see which areas are best for what in their practice.

I find that 

ThermiSMOOTH is great for eyes, cheeks, mouth, and forehead

ThermiTIGHT is great for the neck/lowerface, body, knees/thighs, arms, breast - and more!!

ThermiVA is for vaginal tightening and limited external labia majora and minora tightening or firming up

Thermi250 is a bigger version of the ThermiSMOOTH and noninvasively removes fat and tightens skin on the body - i find it works great in the abdomen, chest, thighs, knees, and arms

Thermi RF

{{ voteCount >= 0 ? '+' + (voteCount + 1) : (voteCount + 1) }}

The technology is Thermi RF or Thermi RadioFrequency that uses heat to shrink collagen and stimulate new collagen to form.  The technology can be used for Thermi Tight which uses a probe that goes under the skin to reach the target area for tightening. It is a single treatment procedure.

Thermi Smooth or Thermi Body is a totally non-invasive treatment that also uses the thermi technology to tighten skin. Usually  you will need 4-6 treatments for an area.

ThermiRF is the machine and technology that is associated with the radiofrequency device. Thermitight is an actual procedure that is done with the ThermiRF machine and involves placing a probe under the skin to heat the underlying structures and stimulate collagen production and skin tightening.

ThermiTight is one of the treatments that can be performed with the ThermiRF machine.   The ThermiRF machine can also be used for ThermiSmooth treatments which are external only.   It can also be used for ThermiRaise treatments to do disable nerves and gives results similar to Botox treatments.

Thanks for your question. ThermiRF is a temperature controlled, radio-frequency device used to tighten, smooth, and sculpt the skin. The different treatments that can be done with the ThermiRF device include ThermiTight, ThermiRase, and ThermiSmooth. ThermiTight is a micro-invasive, non-surgical treatment that treats skin laxity. It is safe and effective for problem areas of the face, neck, tummy, arms, and thighs. Patients may experience swelling, bruising, or redness after the procedure.

They are the same thing - the RF stands for Radio Frequency, but unlike other non invasive RF treatments on the market, this is applied under your skin which dramatically increases the results compared to other methods.
