Unlike conventional liposuction, the idea of noninvasive laser lipo is not to remove fat cells, but to shrink them. During each session, a technician places pads equipped with laser diodes directly onto the the skin. The laser energy penetrates down to the fat cells and creates tiny holes in their membranes. This causes the fat cells to release stored fat, resulting in smaller fat cells. Cavitation then helps to liquify the fat, helping it to drain from the cell even easier.
