Is blistering normal after CoolSculptng?

I am sorry you have had this experience. We have performed many coolsculpting treatments and have never seen blistering afterwards. I would recommended returning to the provider who performed your treatment for further evaluation.

Blistering after Coolsculpting is not typical but can happen if there is a thermal event.  One of the amazing things about Coolsculpting is that the applicators have built in sensors that check your skin throughout treatment to ensure the tissue in the treatment area is not getting too cold.  If the tissue does get too cold the system will shut down and turn off to prevent "freezer burn" on the skin.  Although this rarely occurs, blisters that can result in this situation will typically heal within several days and will not have any lasting side effects.  That being said, it is very important to wait until the tissue is completely healed before re-treating the area.
