I had SculpSure on my stomach area. I experienced diarrhea the next day

Thank you for your question. I suggest that you consult with your board certified facial plastic surgeon. There are no side effects and no downtime associated with SculpSure. You may try massaging your treated area for 15 minutes.
Best wishes,

Sculpsure is a laser treatment that destroys fat cells only a few millimeters below the skins surface, it would be extremely unlikely to trigger the GI concerns you experienced. The fat reduction takes place over many weeks. This seems to be an unfortunate coincidence.
