New EPAT Treatment for Cellulite

EPAT Therapy - The Cellulite Institute and Clinic - Seattle

EPAT (Extracorporeal Pulse Activation Treatment) Therapy

Using high energy acoustic waves that are introduced into the patient’s body in the form of high frequency oscillation, EPAT is effective in treating cellulite due to several effects of the pulse waves.

Skin – promotes tightening of skin, improving the skin elasticity, structure, and contour

Fatty tissue – stimulates lipolysis and activation of metabolism

Circulation – increases blood flow and improves lymphatic drainage

Connective tissue – stimulates and activates collagen formation

EPAT treatment for cellulite has been in use in Europe with good results, as published in the following papers:

“Anti-fibrosclerotic effects of shock wave therapy in lipedema and cellulite,” W. Siems, et. al., BioFactors. 2005;24: 275-282.

“Can cellulite be treated with low-energy extracorporeal shock wave therapy?” F. Angehrn et. al., Clinical Intervention in Aging. 2007 December; 2(4): 623-630.

Shock waves and pulse waves are acoustic (sound) waves that are characterized by high pressure amplitudes and a steep increase in pressure in comparison to the ambient pulse. Even though shock waves and pulse waves are related to ultrasound, they are different because shock waves are comprised of single pulses of especially large pressure amplitudes followed by comparatively small tensile wave components. In contrast, ultrasound usually consists of periodic oscillation with limited band width. The pulse waves generated by the EPAT technology for cellulite treatment propagate through the tissue to an intended target depth, which is rather superficial, within the first couple centimeters from the skin surface. The pulse wave directly and indirectly generates the beneficial effects as mentioned above using mechanisms that are not well understood.

The Cellulite Institute and Clinic uses the CelluPulse 200 EPAT unit to perform pulse wave treatment for cellulite with good clinical results.

FAQs for EPAT Cellulite Therapy

How long is the treatment?
Depending on how many areas of cellulite are being treated, each session of EPAT treatment usually lasts between 20 to 40 minutes. We recommend a total of 6 to 8 sessions over a three to four week period.

Is the treatment painful?
Actually, the staff at the Cellulite Institute and Clinic has developed the physical skills to minimize the discomfort of the treatment by skillfully manipulating the tissue and the direction of the pressure wave pulse. For most areas, such as the thighs and buttocks, the discomfort is usually minimal.

How soon can one see the results?
Usually within the first week one can notice the tightening and smoothing of the skin surface. The effect will be apparent after 6 to 8 sessions, and the full effect will be realized in about 2 to 3 months. The improvement usually will last for one to two years.

What are the potential risks?
The most common risks are temporary, such as bruising of the treated area, pin point bleeding of the skin, and superficial spider veins.

Is anesthetic required for the treatment? Is there any down time?
The EPAT therapy is done in the office without any need of anesthetic or pain medication. The patient can resume all normal activities right after treatment.


The EPAT cellulite therapy is the first line recommendation by the Cellulite Institute and Clinic to effectively treat cellulite. This recommendation is based on the multiple effects of EPAT in improving the following:

The skin tone and elasticity and skin thickness by collagen stimulation

Decreasing the subcutaneous fat cell size by lipolysis, and thus decreasing the fat pockets causing cellulite

Improved local circulation and lymphatic drainage to decrease swelling and inflammation

Stimulation of healing and collagen production

EPAT is a rather simple treatment with multiple benefits!
