I am 5' 5" and weigh 108lbs I will be 60 yo in November 2010. In the past 4-5 months I have noticed a huge change to my arms, Forearms are wrinkled and have loose skin. Now I have sagging skin and wrinkled skin in the upper arms also. I have a stomach pooch that makes it very difficult to wear my size 4, But the clothes are sagging everywhere else. How can I tighten the skin without losing weight? My norm weight is 114.
