Fat Melting In general, fat cells are more resistant to radio frequency electrical current than other skin cells.

Regular skin cells are made mostly of water and fat cells are made mostly of oil.

As oil is less conductive to electrical currents than water, the fat cells heat up more quickly than other skin tissue due to the higher resistance. At a skin temperature of 40°C, the fat cells will start to melt and metabolise.

Skin Tightening Fibroblasts are the connective tissue cells that produce collagen and elastin.

Heating the deeper dermis to a constant 40-45°C stimulates fibroblast action and, in turn, increases the synthesis of new collagen and elastin fibres. This thermal trauma, which occurs to 5-30% of the collagen fibres, causes an immediate contraction of the fibres.

This contraction results in the production of new collagen. The diameter of the collagen fibres in the treated area is increased, and the spaces between the fibres are visibly reduced under a microscope.

This tightens the skin’s appearance and stimulates the increase in blood supply.
