Due to the noninvasive nature of the procedure, side effects from a CoolSculpting treatment session are minimal. Some of the most common side effects reported from CoolSculpting are minor swelling and redness at the treatment site, with these both typically resolving after a few days. Some other side effects include bruising, tingling, tenderness, cramping, aching, itching, or skin sensitivity. If you were treated for submental fat (fat underneath the chin), it is also typical to experience a sensation of fullness in the back of the throat.
It is necessary to schedule a follow-up appointment with your doctor, and to keep them informed of your side effects and healing progress. If you should experience any concerning side effects, or anything not listed, you should notify your doctor right away.
