The Science Of Zerona™ Technology


Zerona™ is the first non-invasive body contouring procedure to effectively remove excess fat without the negative side effects associated with surgical methods. Zerona utilizes the same cold laser technology developed by Erchonia, which has been shown to emulsify fat and allows this fat to move into the interstitial space. Although this technology was originally utilized to help assist liposuction procedures, they found it effective in reducing inches off of the hips, thighs and waist.
The cold laser technology behind the Zerona™ procedure was shown to exclusively release the cellular contents of fat cells while leaving the capillaries and other cells within the interstitial space intact. The release of the fat cell contents is the result of the disruption of the cell’s membrane. This membrane disruption, called a transitory pore, is the result of low-level laser stimulation.



Prior to laser exposure, fat cells have a regular, cluster shape, as seen in Figure 4. Within minutes of low level laser exposure, fat cells begin to develop transitory pores as indicated by arrows in Figures 6-9. This pore allows the evacuation of the cell’s contents into extracellular space (see Figure 7). Once the contents of the fat cell have been emptied (Fig. 10), they are released into interstitial space where it can be passed through the body during its normal course of detoxification.
Through a double blind, randomized, multi-location and placebo-controlled study, the Zerona™ procedure was proven to be an effective non-invasive body contouring procedure. On average, patients lost 3.64 inches from the circumference of their waist, hip and thighs, whereas the placebo group only lost an average of half an inch.
The Zerona™ cold lasers provide patients with a safer alternative to surgical procedures, which can result in bruising, swelling, and damage to other tissues. There is no need to wear bandages with Zerona and since there is no pain, there is no need for anesthesia. Unlike other non-invasive approaches, Zerona low-level lasers do not rely on heating tissue, which can cause discomfort. There is no downtime, so patients can resume their normal activities immediately.
