Hey, Ruby. You are young. Your skin is elastic still. Give it some time, it will return. I looked up some of this online. I can't recall the links, but what I read stated that when you are "young" and lose a lot of weight rather quickly, that happens, but it will tighten up. No need for surgery unless you want "instant" results...The body will react and your skin will do what is supposed to in time. Your body doesn't want to look like a shar pei.
1 pound to goal...
Don't worry I am setting new goal once I get this little pound off!
