What is the boundary area affected by one CoolSculpting Applicator? How far beyond the application area?

Your treatment area will depend on what applicator being use (older/new, bigger/smaller) as they are different sizes and both old and new suction differently and the older applicators it could be a matter of how pullable is your tissue away from your body. You may get a more accurate answer going in for a consultation.

I hope that helps!

CoolSculpting's effects are generally seen in the area of the applicator.  The older applicators rely on suction to expose the tissue to smaller cooling panels while the newer applicators have a more effective and larger cooling region.  The diffusion of the cold generally produces a smooth transition from the area treated to the adjacent regions, but a fat pocket located outside of the treated region is unlikely to be significantly affected and should be treated with an adjacent application.
