Body wraps

I have lost over 100 pounds so far and need to tighten some skin - do body wraps work for the long term?

Congratulations on your weight loss! Unfortunatley, I don't think a body wrap will do anything to tighten loose skin. I also don't think excersise (although it has many many benefits), creams et.. do anything either. Once the skin has lost it's elasticity it's gone. How elastic your skin is depends on genetics, if you've been pregnan, yo yo dieting et.. It's my opinion short of plastic surgery, there is nothing you can do.

I know nothing about body wraps, so can't comment on that.

I can comment a little on building muscle.   Loose skin looks better over toned muscle than untoned.  JMO.
