Will Thermage help will crinkly skin? (Photo)

I am 49 slim and fit with minimum fat. My tummy arms and legs Still have shape but with some sagging despite lots of gym work. My breast are small and the nipples still point forward so I'm not a candidate for a lift as don't want implants. My body skin particularly under my arms, boobs and tummy has developed a papery wrinkly appearance all of a sudden. I've tried everything. I have been quoted a high price for thermage which will be worth it if it can improve the skin quality. Advise please.
