I am curious to know, in terms of biology, how does the butt sag when you are too young to experience this? Recently, I've experienced trauma to lateral portion of my buttocks causing the fat to confine to the lower region. I am guessing that the trauma to the connective tissue causes it to relax and therefore elongate itself as well as the collagen it secretes. But I could be wrong..... How does one go about correcting a pseudo-ptotic issue look this? In other words, how do you tighten the connective tissue/collagen?
