CoolSculpting works by eliminating small amounts of fat, unlike liposuction, which removes more significant amounts and is more invasive. The former is noninvasive and freezes fat cells (cryolipolysis), eliminating them throughout your body, thus producing less dramatic results. The only side effects to worry about are partial bruises and skin sensitivity, which subside after a few weeks. Also, it takes a few weeks to see the results because there’s a little-to-no recovery period.
