The specific fat cells removed during an AirSculpt procedure cannot come back, because the patented mechanical technique permanently extracts and eliminates those cells from the body. Adult humans do not generate new fat cells in treated areas. However, patients must understand that weight gain can still occur overall. If a patient consumes excess calories and fails to maintain a stable lifestyle, the remaining fat cells located in untreated parts of the body—or any microscopic fat cells left behind—can expand significantly, altering overall body contours.
