Zeltiq CoolSculpting - Are There Any Side Effects?

The most common side effects from CoolSculpting are temporary swelling, bruising, numbness, and a tingling sensation. These side effects generally last only a few days to two weeks at most, although the numbness may last for longer. Most patients are able to return to work immediately following a treatment, and are able to manage side effects easily with over the counter medication. Be sure to always see a board-certified, experienced dermatologist for any CoolSculpting treatment.

Major side
effects or complications are rare following a CoolSculpting procedure because
it is noninvasive. There are no incisions and no injections. Most patients
return to work or normal activities immediately after the treatment. You may
see some redness in the treated area, which could last just a few minutes or up
to a couple of hours. Swelling might also occur and could last a few weeks
before completely fading. A dull sensation is another known side effect,
lasting from 1 week to 2 months.
