According to Dr. Johnson of Innovations Medical, under our skin is a layer of deep fat cells, and under that is muscle. The deep fat cells have connective tissue between the cells and it is this structure of connective tissue that holds the fat together. Almost all the volume is the actual fat cells. When doing liposuction the fat cells are removed and literally vacuumed out of the body. Most of the connective tissue is left intact. Over about six weeks to two months the skin will begin to collapse or shrink. Because the large fat cells are no longer to take up space, the skin it will able to return to its former shape.
