When the laser paddles are placed on the skin, the Class 2, 3B lasers penetrate the skin just deep enough to reach the layers of fat (9-13mm). When the fat cells absorb the energy from the lasers, a rapid chain of events take place. Firstly, pores form on the surface of the cells causing them to spill out their contents of water, Glycerol and free fatty acids. These contents moves into the interstitial space beneath the fatty layer in the skin which enables the cells to become malleable, achieving adipocyte cell reduction. This disruption does not affect the neighboring structures such as the blood vessels and nerves.
