Does coolsculpting physically remove fat cells from your body or just shrink them?

Coolsculpting is designed to gradually kill fat cells through a process called cryolipolysis. Stubborn fat cells in a localized area are treated, freezing the cells and sending them into a slow death. Over the course of 1-3 months these dead fat cells will be gradually eliminated from your body, so they are permanently removed. Coolsculpting can effectively kill 20-25% of fat cells in an area per treatment. Hope this helps.

Zeltiq's
CoolSculpting system uses a patented technique called cryolipolysis
to send fat cells into slow cell death (apoptosis) by lowering their
temperature to the point where they freeze. The drop in temperature,
however, is not enough to adversely affect surrounding tissue because
fat cells are more prone to cold injury than other cell types. The
cells take days to weeks to die. After the cells have begun to
destruct, their components are consumed by macrophages, which are
part of our lymphatic system and are designed to digest and expel
cellular debris. The cell components are then excreted from the body
via the urine. Thus, the fat cells have not been shrunk, they have
been destroyed and removed from the body. Long-term studies suggest
that these cells cannot re-appear. However, if you over-eat, the fat
cells that remain in the area treated by CoolSculpting can expand,
leading to the development of another fatty deposit. That's why it's
so important to be committed to a healthy diet and exercise regimen
even before having a CoolSculpting treatment. Please find a
board-certified dermatologist who has been certified by Zeltiq as a
CoolSculpting practitioner to remove your stubborn fat so you'll be
beach-ready by summer.
