Fat dissolving product contains deoxycholic acid, which is naturally found in the body.
This compound aims to break down the membranes of fat cells, causing them to degrade; the leftover components of the dead cells are then naturally removed from the body.
Dissolving of fat cells is permanent, but may require at least two treatments per area. However, a healthy lifestyle must be maintained, or new fat cells will simply grow back and repopulate the area.
