I was worried about the same thing. My wife lost a lot of weight and had some pretty loose skin, so much so that it folded over some. That was a couple of years ago and it seems to have righted itself. I've read that after fifty, which we both are, the skin starts to lose elasticity. As a preventative measure, I've been using some skin firming lotions. So far, so good, although I haven't a clue as to whether it can be attributed to the lotions I'm using. One thing is for sure: I have very soft, moist skin from using them. I tend to dry out easily and they surely help in this regard.
