CoolSculpting on Lower Abdomen - Large Handpiece or 2 Smaller Handpieces?

With CoolSculpting, you have the two handpiece sizes (thus far) - The larger one grabs considerably more fat than the smaller one. If your abominal fat is centralized, then the one larger handpiece (or cup) is the most efficient, both from a time and cost perspective.

This eliminates any potential two-handpiece "treatment overlap" which can cause some additional tenderness and side effects. So when possible, opt for one larger handpiece.

On the other hand, if your fat is more laterally focused - outside so that the single large handpiece won't grab hold of the entire width of the area you want to treat, then the two smaller handpieces will be your choice.

A careful technician will be able to consecutively treat side by side areas without undue overlap.

The only important thing is to make sure the applicator that is applied fits well and covers the maximum area possible. Even if you need the large applicator on the lower abdomen, you may need a separate treatment on the upper abdomen and a small applicator may be the only one that fits you there.
