CoolSculpting is a low-risk and safe procedure for most people. As long as you’re a candidate, you shouldn’t experience painful after-effects. Common side effects are mild and temporary. For a few days after the treatment, it’s normal to notice swelling or a decreased sensation in the treatment area. To avoid fainting or getting nauseous, we recommend drinking plenty of water after the procedure. Clear fluids will not only keep your body hydrated but help facilitate the removal of dead fat cells.
