umm it is perminent, i didnt use my corset for over a month but kept the inch loss. And even now i only use it 4-8 hours a day 2-3 times a week. but ive still managed to comfortable lace down the full 4 inches. Also, perminent inch loss isnt that uncommon, as it can help control over eating so naturally you'd lose weight my ribs havnt moved as far as im aware, my waist has gotton smaller, but yea i imagine that would take years to achieve.
