The Science

The Thermi250™ (sometimes called ThermiSmooth® Body) is a painless solution for skin laxity, small areas of fat reduction, contouring, tightening, and cellulite across the whole body. Over one or more visits, an external handpiece beams targeted energy, heating the layers of fat and tissue and stimulating fibroblasts. The Thermi250 is a popular choice for areas of the skin that are more prone to laxity: crepey knees and elbows, or a postpartum abdomen. These regions can be giveaways for individuals who are otherwise in great shape.

Our Approach

Thermi250 uses the same radiofrequency technology as the ThermiSmooth®, but the energy pulse is calibrated to improve skin tightness on the body. This can also help stimulate collagen remodeling, so your body will naturally tighten and improve skin laxity. More commonly, Thermi250 is used on the body to help tighten skin without resorting to surgery. (Because of the nature of the technology, patients must remove all piercings and metal jewelry, including hearing aids.)

What to Expect

Length Of Procedure

Depending on the size of the treated area, Thermi250 can take anywhere from 25 to 60 minutes.


Thermi250 patients should begin to notice increased tightness several weeks after treatment. As collagen remodeling occurs over the next 6 months, results should continue to improve. How long the results last will be different for every patient.


A painless, noninvasive procedure, Thermi250 requires no downtime, and patients can often return to work shortly after. During the session, the skin may feel warm or a bit hot; afterwards, it may appear to be slightly red for a few hour.

It may help your recovery if you drink at least 8 glasses of water throughout the day after receiving your treatment.

Number of Treatments

We recommend a series of at least 3 to 4 treatments, with 4 to 6 delivering optimal results (depending on the patient’s expectations). These treatments should be spaced 3 to 4 weeks apart.
