"RFAL candidates would be anyone who is seeking lipo surgery, who wants less pain, bruising and discomfort on recovery, as well as optimal soft-tissue contraction," says R. Stephen Mulholland, M.D., a board-certified cosmetic plastic surgeon with private aesthetic practices in Toronto and Los Angeles, and president and director of SpaMedica Infinite Vitality Clinic, Toronto.
RFAL REVEALED The RFAL device is a one-stage thermal-assisted lipoplasty technique that differs from other liposuction methods with its use of radiofrequency to liquefy and coagulate the adipose and vascular tissue while it is aspirated.
"It's similar in concept to laser liposuction or laser lipolysis in that it uses an energy methodology to preliquefy the fat," Dr. Mulholland says.

"The big advantage is that you're heating, liquefying and coagulating while you're aspirating. So it's one stage, and it's faster than existing energy-assisted liposuction methods," he says. "In addition to being faster than other thermal liposuction systems, published studies show the uniformity and efficiency of RFAL allows for average area soft-tissue contraction of 30 to 40 percent, making some marginal skin-laxity patients candidates for RFAL rather than more aggressive excisional techniques."

RFAL is also a more energy-efficient system than others on the market. "The number of effective joules and heat you can deliver in the tissue is much higher than you can get with laser or ultrasound, just by the efficient nature of radiofrequency current," Dr. Mulholland says.
Despite the increased power — up to 75 watts — the BodyTite device is also safe, with a minimal risk of burns resulting from a negative feedback loop. It takes continuous internal and external measurements of impedance and temperature. "If any of those parameters have been exceeded or there is any suggestion from the internal temperatures that we may be overheating tissue and heading towards a burn, it will cut off the radiofrequency energy," Dr. Mulholland says.
Burns are still possible, though Dr. Mulholland cites a less than 1 percent chance. Seromas are also a potential risk, but only in 1 to 2 percent of cases.
