A mini tummy tuck, also known as a mini abdominoplasty, is a surgical procedure that tightens loose skin on the lower abdomen between the area of the belly button and the pubic region. In comparison to a full tummy tuck, a mini tummy tuck involves a much smaller incision across the lower abdomen, while the region of the belly button is left intact. A mini tummy tuck does not remove fat from the upper abdomen like a regular tummy tuck does.
