Can Thermage help with sagging skin on my upper arms and thighs?

I am in my seventies and have some loose skin on my neck. Could Thermage solve this problem, or is there a better alternative you could suggest?

I have significant stretch marks and loose skin after losing 81 lbs. I am 5'3" and currently 124 lbs and looking to tighten up the loose skin on my abdomen. Will Thermage give me the results I'm looking for?

I had a contour thread lift 7 years ago (2 threads on each side of the lower face). Is it OK to get a Thermage treatment?

Is this the best procedure for removing stomach fat?

Many products and procedures claim the effects of a "non-surgical face lift". Is there anything, other than a real, surgical procedure, that will give me the look I achieve when I place my fingertips at the top of my jawline and lift an inch? - Jowels

My esthetician said that thermage may work to reduce the appearance of my acne scars, but most of the reviews I've read online just talk about it as a wrinkle treatment.
