How it works, and common myths

Gentle heat damages fat cells, and your body clears them over a few months.

A little more technical

The device heats the fat layer for about 25 to 30 minutes while the skin is protected. The body clears the damaged fat cells over about 6 to 12 weeks.

Energy-based hyperthermia of subcutaneous fat damages adipocytes while the skin surface is cooled or protected. The damaged cells are cleared by the body over weeks.

Energy type: Heat energy; A laser, radiofrequency field or microwaves warm the fat layer while the skin is protected.
Mechanism category: Fat cell clearance; Fat cells damaged by heat are cleared by the body over several weeks.
