ThermiRF® Skin Tightening (ThermiTight®, ThermiSmooth® Body, ThermiSmooth® Face) - San Francisco, CA

33 Procedures ( View All )


ThermiRF is one of the latest technologies in minimally invasive cosmetic procedures using radiofrequency to raise the temperature where applied. This rise in temperature penetrates deep into the skin to stimulate collagen, elastin, and even melt fat for smoother, tighter, more youthful-looking skin. Patients today are seeking less invasive solutions to reduce wrinkles, tighten skin, and melt fat with great results and little downtime. ThermiAesthetics has satisfied the current demand for a fresh, youthful look without surgery by developing a micro-invasive skin tightening and fat melting procedure performed under local anesthesia.

Dr. Leonard Gray, F.A.C.S., of Bay Area Plastic Surgery, was the first board-certified plastic surgeon in Northern California to have ThermiRF. He is also an active member of the Clinical Advisory Council for ThermiAesthetics. Dr. Gray is confident that this is the answer for patients who want the “in-between” procedure— not quite surgery, yet producing much better results than noninvasive procedures.

The minimally invasive skin-tightening technique is very popular among Dr. Gray’s patients. Commonly treated areas to tighten loose skin include:

  • Face and jowls
  • Neck
  • Brow
  • Upper arms
  • Knees
  • Abdomen

Procedure Process

During your Thermi treatment, Dr. Gray will numb the area with local anesthetic and insert the Thermi probe through an incision about the size of the tip of a pen. The probe heats the collagen connective bands in the sub-dermal area, which results in immediate tightening of the skin and surrounding tissues. The thermal effects causes continual skin-tightening for several months. Because of the tiny incision, stitches are not used and scars are virtually non-existent after healing. The full results of your ThermiTight treatment are visible at about 4 months post-procedure.

What to Expect

RF skin tightening can be uncomfortable for some patients because of the heating sensation. At Bay Area Plastic Surgery, we give our patients an option to take oral pain and anti-anxiety medications during their treatment to increase comfort.  Before the heating occurs, Dr. Gray will apply numbing solution to the treated area for optimal comfort. 

After the treatment, some redness and swelling will be visible. This will subside after a few weeks. The majority of the swelling will occur in the first week.  Tightening sensations may be felt right immediately after the treatment, and will progress as the weeks pass to result in smoother and more supple skin. The effects of skin tightening can be long lasting. 

RF Skin Tightening FAQs

Who Is It For?

If you have aging or loose skin, need some rejuvenation, yet still want to look like a natural “best version” of yourself, but don’t have the time to commit to a surgical procedure, this is the perfect treatment for you. Schedule a complimentary consultation with Dr. Leonard Gray to find out if Thermi will give you the results you are looking for. 

Long-Term Outcome?

The results may be long term since the treatment is not superficially limited and multiplies collagen. The improved skin can last up to 2 years. It is important for the patient to understand before undergoing the procedure that this treatment does not stop the skin’s aging. There are cases in which an RF treatment is repeated when the patient or doctor deems it necessary.

Other Considerations

The FDA cleared ThermiRF in November 2013 for general surgical applications in soft-tissues; it had previously been cleared by the FDA solely for treating nerves. ThermiRF uses controlled radio frequency, or “RF”, which merely increases the temperature under the skin where it is applied. The unique characteristic of Thermi is that it has multiple uses. Depending on the temperature, depth, and area in which the probe is being inserted under the skin, it can tighten skin and tissue, melt fat, or permanently relax frown lines just like BOTOX®.
