This is a complex answer and may be beyond what you are asking.
Laser lipo is supposed to me similar to mesotherapy in that you use the laser as a modality to achieve fat cell destruction. Mesotherapy uses detergent like agents to accomplish the same. In either case, the fat cells rupture and release triglycerides and lipids which are taken up by the bloodstream. The effect of this on your health is unknown. These fats are in molecule form.
However, when traditional liposuction is conducted (usually following laser liposuction), trauma to blood vessels can cause whole fat cells to enter the bloodstream, a process that is called a "fat embolus". Fortunately this is extremely rare but occurs following liposuction or large bone fractures. It can have serious consequences but occurs extremely infrequently.
