Adipocyte (Fat Cell)

Adipocytes are the cells that store energy as fat, sitting in the subcutaneous layer beneath the dermis. Their number is largely fixed in adulthood, which is the scientific basis for non-surgical fat reduction: destroy a portion of them and that fat-storage capacity is gone for good.

Different technologies attack adipocytes differently. Cryolipolysis cools them to a temperature that triggers apoptosis (programmed cell death), after which the body clears them over weeks. Ultrasonic cavitation ruptures their membranes mechanically, releasing the stored triglycerides for lymphatic clearance. Laser lipo (LLLT) stimulates them to release their contents without destroying the cell. Injection lipolysis chemically dissolves them. The distinction between ‘destroying cells’ and merely ’emptying’ them is what separates permanent from lifestyle-dependent results.

For body-contouring clinics, knowing the adipocyte mechanism behind each device clarifies what to promise clients.
