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.

ThermiSMOOTH or ThermiTIGHT for eyes and face

Dear ssl:

Facial aging occurs differently at each level of the skin.

  • An accumulation of scaly cells creates the dry, rough surface with fine lines at the epidermal level.
  • Passive reduction of regeneration occurs in the dermis causing thinning, laxity, wrinkling and folds. This is the primary layer for skin firming and tightening. Controlled injury to the dermis will upwardly stimulate regulation and exfoliation of the epidermis.

ThermiSMOOTH uses  controlled monitoring of RF (radio frequency) energy to deliver heat through the epidermis to the dermis.  This differs from other sources of energy using laser which must “blast” high energy to a chromophore to generate heat; either creating intolerable pain or ineffective heat to tolerate the pain.  ThermiSMOOTH delivers a gradual heating to the proper thermal point for contracture of the dermal molecules and controlled inflammatory collagen production.

ThermiTIGHT uses the same controlled RF generating and heat monitoring devices via a subcutaneous needle-sized probe to deliver heat directly to the subdermis. This allows a more efficient and tolerable procedure as it uses lidocaine to fully control pain as well.

  1. ThermiSMOOTH best delivers around the eyes and lips. I find it synergizes well with Sculptra dermal collagen stimulation.
  2. ThermiTIGHT is terrific in the loser tissues of the submalar cheek, jowl and neck.
  3. IPL is best for broken capillaries and any telangiectatic capillaries created from collagen stimulatory procedures such as those above.

I hope this is helpful. Always consult with a talented and skilled, Board Certified Plastic Surgeon who may properly evaluate and recommend those non-surgical, minimally invasive and surgical procedures selected best for you. All the best!

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

Thermi is a radiofrequency energy that treats the connective fibers under the skin with heat. It causes secondary tightening. It's minimally invasive and is usually performed in the office.

ThermiVA is for vaginal rejuvenation. It is done without any anesthesia and is painless.

ThermiTight treats the subcutaneous tissue directly with a RF probe and is done under local anesthesia.

ThermiSmooth is for external delivery of RF heat for thinner skin areas such as the eyelids. This is also painless and non-invasive.

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.
