How to accurately correct thin, dry, loose skin? (Photos)

Hello. I am 35, 5’2, 135 pounds. I am very concerned about my skin letely. It feels extremely thin, dry and loose. NI have never been heavier than my current weight and i excercise about two times a week. I am considering bodytite but am afraid that i will loose more dermal fat. My feet and hands are pure bone and cant imagine loosing any more. Is this collagen or elastin loss? Is there a procedure that could tighten skin deep down to the fascia without loosing fat?
