With a full tummy tuck all of the stretch marks beneath the belly button will be removed. Depending upon how loose the skin is, some of the stretch marks above the belly button will be removed. Even if the upper stretch marks are not removed, they are at least shifted strongly downward. Though a stretch mark is actually a scar, which means that it is an indelible mark in the skin, by tightening the skin with an abdominoplasty the stretch mark becomes taught and thereby is typically much less visible.
