Side effects included swelling, redness, bruising, and some pain, but there were no serious side effects such as infection.
“It does reduce fat volume and thickness and side effects were predictable,” Young says. “Treatment of small areas of fat is a realistic expectation and a tool for people who want less invasive procedures and fear anesthesia.”
But it’s important to know what you are being injected with, he says. “You need to know who produces the cocktail and what was done to it after it was received,” he says.
As far as where the melted fat goes, it is not leaving the body, Young tells WebMD. “It has truly the same fate as fat you would eat,” Young says. It will migrate to other areas of the body with fat cells, including the arteries.
“You are not going to have a heart attack from this though because the amounts of fat are so small,” he says.
Jeffrey M. Kenkel, MD, a professor and vice chairman of plastic surgery at the University of Texas Southwestern Medical Center at Dallas and director of the Clinical Center for Cosmetic Laser Treatment in Dallas, says that lipodissolve is “another option for treating small areas of fat such as under the chin, and revisions of small lumps and bumps after liposuction.”
Renato Saltz, MD, the immediate past president of the American Society for Aesthetic Plastic Surgery (ASAPS) and a plastic surgeon in Salt Lake City, was also surprised by the study results.
“The study results are positive, but it is still a very small sample, so we have to be cautious regarding our final recommendation,” he tells WebMD. “Most of us felt that there was no application for mesotherapy (a procedure similar to lipodissolve) and had seen or heard of disasters abroad, so when it started coming here, we were very concerned,” he says.
Questions do remain, he says. "The new study was on a small group of people by a 'superb' surgeon, but are the results reproducible?” he says. The next step is to expand the study.
The bottom line? “Stay tuned,” Saltz says.
