To a DEGREE, compression wraps can help (ESP while in the process of losing weight, and thereafter... Just so the skin doesn't stretch further / is y fighting gravity as its trying to tighten up)....
... But only to a degree. I used to have 3" of belly "smile" (Ugh. Not.). Now I have 1. Its still AWFUL. And, nope! Nothing short of surgery shall fix it. Nor my arms. Nor thighs. Skin is inherently stretchy. But once the bonds have been broken, they're broken. I have 30lbs of excess skin (just skin). Its awful.
But until I can nip tuck, Im stuck with it.
Think like a balloon. Stretchy, yes? But if overs fetched, it never goes back to the way it was.
