Renuvion for arms - will this work for me? (photos)

Hi. I am a 52 year old female and I have been self conscious of my arms my whole life. I eat right, workout and have even tried ultherapy (zero difference) and cool sculpting (minimal difference if any, and going multiple times was too expensive, I also thought the paddle was too small). Oh! And I tried laser rx radio frequency! None has helped and I feel stupid and duped for throwing good money after bad. So now I’m reading about Renuvion. I would really like to know if it will work. TY
