I received 2 or 3 carboxy treatments in my thighs over 1 year ago in hopes of tightening that area. According to the Dr, the gas was "flowing very well" and during the treatments, the front & back of my thighs inflated to about twice their normal size temporarily. Now, the skin on my thighs is extremely loose. I'm also aging, which could be a factor. But I just can't understand how stretching the skin that much is beneficial. Is it?
