Thank you for your question.
Although a compression garment will not hurt, I do not think it will significantly help either. With CoolSculpting, the reduction of fat cells is gradual and there is minimal swelling associated with the procedure so you shouldn't need the garment. But.... if you want to wear one, again, it won't hurt.
Compression garments are not required after a CoolSculpting treatment. With CoolSculpting, the fat reduction is gradual and less than the fat reduction with liposuction and there is usually not as much swelling as you would have with liposuction. Sometimes patients still wear them for comfort after CoolSculpting, but it will not significantly affect your end result.
There is no mention by the scientific division of Zeltiq that compression garments are needed for CoolSculpting to more effective or to decrease bruising. The use of compression garments, however, is part of the normal post operative regimen after liposuction because there are empty channels that are created by the suction removal via long thin cannulae instruments. The compression helps collapse these tunnels so the collagen can build a stronger tighther infrastructure and cause less bleeding. None of this occurs with CoolSculpting.
Liposuction requires compression garments because of the immediate tissue loss. Because coolsculpting is a slower mechanism and does not result in immediate results, then no compression garment is needed
We have done many Coolsculpting cases and we do not use a compression garment. There is no reproducible published evidence that this has any effect on the results.
