Anyone have any advice for how to get rid of the wrinkly flabby skin left after having a baby (via c section) I'm only 18 and I got told my skin would eventually pop back to normal because of being so young but I've been left with tons of stretch marks and like a pouch, anyone have any tips/exercise etc they could give me? Anything is appreciated thank you
