CoolSculpting uses a procedure known as cryolipolysis. It works by placing a roll of fat into two panels that cool the fat to a freezing temperature.
A 2009 study Trusted Source looked at the clinical efficacy of cryolipolysis. The researchers found that cryolipolysis reduced the treated fat layer by as much as 25 percent. The results were still present six months after the treatment. Frozen, dead fat cells are excreted out of the body through the liver within several weeks of treatment, revealing full results of fat loss within three months.
Some people who do CoolSculpting opt to treat several parts of the body, usually:
thighs
lower back
belly
sides
It can also reduce the appearance of cellulite on the legs, buttocks, and arms. Some people also use it to reduce excess fat underneath the chin.
It takes an hour to treat each targeted body part. Treating more body parts requires more CoolSculpting treatments to see results. Larger body parts may also require more treatments than smaller body parts.
