The Cosmetic Surgery Procedure for loose and sagging skin that can be a consequence of geing, pregnancy,certain genetic skin conditions, and major weight loss can result in lax hanging tissues is called Body Lift.
Body Lift Surgery often involves several stages to address the entire body: Lower Body Lift (normally tummy tuck procedure), Breast Lift, Arm Lift, Upper Body Lift among other sculptures.
Lower Body Lift
You should always remember that there are risks associated with a major surgery like a Cosmetic Procedure like this one.
Remember that a Body Lift is not a alternative to losing weight or a motivational tool.
I am not recommending you to get a cosmetic surgery at all. I just present this information here for your convencience and information. Make sure you see a qualified surgeon.
You could try for non-invasive procedures before making the big decision of going through the knife.
Zerona Slimming Laser for Fat Reduction is an alternative.
