The damaged fat cells don’t immediately leave your body after CoolSculpting. Instead, they crystallize and eventually die. Your body then works to remove the dead fat cells, creating a slimmer silhouette. How dramatic your results are and how long it takes for them to be visible depends on a few different factors.
While some people might notice a difference after just one treatment session, many need two or more to see a noticeable change in the size of their waistline or in the circumference of their thighs. The treatment can remove up to 25 percent of fat cells from an area, but it can often take multiple sessions to get that result.
It’s also worth noting that results can take as long as 16 weeks (4 months) to become visible. It all depends on how quickly your body is able to eliminate the destroyed fat cells. One of the benefits of the treatment, though, is that once those cells are gone, they are permanently gone.
