The technology
How cryolipolysis (fat freezing) works
A cryolipolysis applicator draws a fold of skin and fat into a cup with vacuum and holds it between cooling plates at a controlled temperature, typically between -5 and -16 C, for 30 to 60 minutes. Fat cells are more sensitive to cold than the skin, nerves and vessels around them: cooled long enough they undergo apoptosis and are cleared by the body over the following 8 to 12 weeks, while the skin recovers within hours. The result is a measurable reduction in the thickness of the treated fold rather than weight loss, which is why the technology is sold for stubborn pockets on the abdomen, flanks, thighs, arms and under the chin rather than for overall slimming.
What the operator controls
- Temperature. Lower is more aggressive; the HS1000A is specified down to -16 C. Protective membranes between the plates and the skin are a consumable on every cryolipolysis system.
- Vacuum. The HS1000A runs up to 100 kPa suction per handle; strong enough to hold a dense fold, adjustable for delicate areas.
- Time. 30 to 60 minutes per cycle; after the cycle the fold is massaged to break up the cooled tissue.
- Applicator shape. Cup sizes and 360-degree heads (the HS1000C's six applicator heads) decide which areas can be treated and how evenly the fold is cooled.
Heating modes
Some platforms, including the HS1000C (heating levels 0 to 4), warm the tissue before or after the cold cycle. Manufacturers position hot-and-cold cycling as a way to improve comfort and the post-treatment massage step; it is a protocol choice rather than a different technology.
