What is the difference between Thermi Smooth, thermi Tight and thermiRF?

I am interested in one of these for facial tightening including eyes. Can't tell what is the difference between these. Also, is there something better out there that can target both tightening of the face and eye area and broken capillaries?

Thermi Procedures Defined

Thermi Aesthetics is a company that has a new and innovative product that treats a number of candidates using Radio frequency called ThermiRF.The specific treatments are as follows:

1.) Thermi Tight: a small probe used under the skin to create significant tightening of areas such as: neck, abdomen, arms and breasts.This is a single treatment.

2.) Thermi Smooth: a smooth round probe used on the surface of the skin of the face such as crepey skin around the eyes or lines around mouth. This requires 3 treatments, 3 weeks apart.

3.) Thermi Rase: Toxin free disabling of nerves that can smoothen lines of the face, laxity of the neck muscles with long term results (up to 1 year or more).Alternative to Botox or Xeomin.

4.) Thermi Va: Female tightening of internal vaginal laxity or external laxity. Completed in 3 comfortable surface treatments.

ThermiRF provides ThermiSmooth and ThermiTight skin tightening in my NYC practice

ThermiAesthetics, a company, has produced ThermiRF, a radiofrequency energy source that can be delivered to the dermis underneath the epidermis, by an external energy delivery without downtime using ThermiSmooth.  An injectable form of this energy is done with ThermiTight using local numbing first. There is some down time with this procedure, mostly associated with some visible swelling for several days, and is usually done as one treatment but ThermiSmooth is done as a series of treatments, often done every two weeks but does not cause swelling. 
There is also ThermiRaze which is entirely different but also from the same energy delivery as ThermiTight and this is designed to produce a Botox-like effect for frown lines and this causes swelling temporarily too.
I appreciate the amount of research this company has done and provided physicians with internal and external safety mechanisms that are unparalleled and also provide doctors an opportunity to share their experiences and knowledge frequently which helps all of us develop the best protocols possible.

Thermi - ThermiTight vs ThermiSmooth

ThermiRF is the general machine that can perform ThermiTight, ThermiSmooth, and ThermiRase.  ThermiTight is for tightening *under* the skin which can be performed of the face and neck, arms, abdomen, and other body areas.  ThermiSmooth is *topical* radiofrequency and heat and can also be used on many body areas.  You can use ThermiSmooth for tigthening of the face and eye area.  Thermi will not help broken capillaries.  Both modalities are very effective for non-surgical tightening of the targeted areas.

Differences between Thermi smooth and Thermi tight treatments

ThermiRF is the name of the machine itself. This machine can be used to perform the
ThermiTight procedure where a small puncture site is made, anesthesia
is injected, and then a small probe is gently passed just under the skin
delivering the RF energy deeply to the tissue. ThermiSmooth is
entirely non-invasive and uses a different probe to deliver the same
type of energy on top of the skin, heating the tissue topically.

ThermiTight and ThermiSmooth both use the ThermiRF system

ThermiRF is the general radiofrequency energy system that all of the Thermi devices utilize. ThermiTight is a skin tightening device that uses a probe inserted under the skin to deliver radiofrequency energy to deep tissue, and is most often used to reduce the appearance of jowls and tighten skin on the neck, arms, thighs, abdomen and other areas of the body. ThermiSmooth can be used to tighten the skin on the face including the eye area. It delivers radiofrequency energy topically, without the probe, and is best for smoothing fine lines and subtly tightening the facial skin. The Thermi 250 is a more advanced tightening system like the ThermiSmooth and is used to tighten skin on the abdomen and thighs in addition to minimizing the appearance of fatty deposits in those areas.As for broken capillaries, ThermiRF will not treat those. A treatment such as IPL (intense pulsed light) or PDL (pulsed dye laser) should be used instead.

I Love Thermi Everything!

Great question, thank you!  It can be a little confusing with so many similar names.  ThermiRF is a general term that can refer to the company, or any of their treatment devices or protocols.  "Radiofrequency" is what the "RF" stands for and that is the energy modality upon which the entire platform is based.  The full list of Thermi treatments is as follows:  ThermiTight, ThermiRase, ThermiDry, ThermiVa, ThermiSmooth, and Thermi 250, formerly ThermiSmooth 250 prior to FDA approval, which occurred in November of 2015.  ThermiVa, ThermiSmooth and Thermi 250 are all non-invasive, non-painful office procedures that may be performed by an esthetician, nurse, or other licensed health care provider (HCP).  All the others are minimally-invasive and require local anesthesia to numb the area being treated and must be performed by an HCP.  In my career, I have not seen a radiofrequency device live up to all its claims like Thermi has.  For the face, you could use Thermi 250, ThermiSmooth, or ThermiTight.  ThermiTight will likely give the most dramatic result, but is also a bit more expensive and does require local anesthesia.  None of these will do anything about spider veins.  Nothing currently on the market will tighten skin like ThermiRF, I am convined.

Difference between Thermi treatments

ThermiRF is a radiofrequency energy delivery system developed by Thermi Aesthetics. ThermiSmooth is a non-invasive device that uses ThermiRF to help tighten and smooth the skin on the face, including around the eyes. ThermiTight uses a probe inserted under the skin to deliver the RF energy, and can be great for helping to reduce jowls and loose skin on the chin and neck, as well as for reducing fat. Broken capillaries around the nose are best treated with IPL or V-beam, which specifically target red pigmentation.

Thermismooth RF is a non invasive, in office radiofrequency skin tightening treatment that helps correct the fine lines and wrinkles around the eyes and mouth. You may also see an improvement to the jowls and neck with Thermismooth RF. 3-4 treatments, spaced 2-3 weeks apart is required for optimal results. Almost anyone is a candidate for this procedure.

Thermitight can only be administered by a physician. This involves a tiny poke to allow the RF probe to enter the skin. Thermitight works well for the neck, arms, back/flanks, abdomen and thighs. One treatment is enough to see quite an improvement. There is a little down time associated with Thermitight, swelling is the most common complaint and subsides over 3-5 days.

Neither of the above RF treatments improve broken capillaries. You may want to consider looking into the ND Yag laser for this.

Difference between ThermiSmooth, ThermiTight, and ThermiRF

Thanks for your question. ThermiRF is the "umbrella," and it is a temperature controlled FDA-approved, radio-frequency device used to tighten, smooth, and sculpt the skin. Radio-frequency is a type of electrical energy that can be controlled and thereby stimulates collagen production in the targeted area(s).

ThermiTight is works well for problem areas of the face, neck, abdomen, arms, thighs, and other tissues (i.e. bra fat, love handles). ThermiSmooth works good for cellulite on thighs.

What is the difference between Thermi Smooth, thermi Tight and thermiRF?

The ThermiRF is the RadioFrequency energy generator that utilizes the latest technology using the "Science of Heat" to reduce wrinkles, tighten skin, reduce fat, and reduce cellulite.

The ThermiTight, ThermiSmooth, and ThermiSmooth250, and the latest ThermiVA are attachments that are designed to deliver this radiofrequency to different tissues.

The ThermiSmooth and the ThermiSmooth250 deliver the highly controlled heat topically with small hand-pieces to the skin, raising the temperature to about 45 degrees centigrade. This is a temperature that tightens collagen, diminishes fat and reduces both wrinkles and cellulite with no discomfort or downtime. The treatments usually take about 4 treatments.

The ThermiTight requires local anesthesia and requires a very small probe just under the skin to deliver heat for the same purpose of tightening skin, reducing fat, and cellulite. This requires only one treatment and effectively "melts" the fat while tightening collagen and elastin. Highly controlled temperatures of up to 70 degrees C. can be achieved because it is delivered directly under the skin. The ThermiTight can be used virtually anywhere in the lower face, neck, body, legs and arms. There is some swelling and recovery time, although it is a minimally invasive procedure. The recovery is mostly non-limiting regarding daily activities, except for exercising.

The ThermiVA uses the same ThermiRF generator, but as with the ThermiSmooth, the heat is applied topically to the vaginal area to tighten both the external and internal vaginal area with reduction in size of up to 50%. This treatment is totally comfortable and usually requires 3 treatments.

A much appreciated side effect of the ThermiVA is a reduction or elimination of stress incontinence. Stress incontinence can a most debilitating complication following pregnancies with vaginal deliveries, limiting activities such as exercising, sports and causing leakage while even laughing or sneezing.
