Is it ok to use a Slendertone ab toning belt after CoolSculpting on the hips and/or abdomen?

there are no physical restrictions post treatment with Zeltiq's CoolSculpting, so if you wish to use a toning device, whether it be vibrational, ultrasonic or electromagnetic or of other energy source, it should not interfere with your results. Please ask your physician who performed the Zeltiq treatment.

The Slendertone belt is electrostimulation that works on the muscle fibers so you should have no problem using it after a Coolsculpting treatment.  You can go back to all of your regular activities and exercise immediately after treatment.  Keep moving toward your goal of  smoother hips and a flatter tummy.  It won't be one thing that gets you there...it'll be a combination of good eating habits, exercise, treatments/procedures and other adjunctive therapies.  Good luck.
