Body Shrink effects and swelling reduction for sagging inner arms

With summer approaching, I am very self-conscious because the flesh on the inner upper arms jiggles and sways whenever I move my arms while wearing sleeveless tops or thin shirts. No matter how intensely I work out my arms, the fat in this area doesn't seem to come off easily, and it feels like only the skin barrier elasticity keeps decreasing, so I have started considering professional medical procedures. I heard that Body Shurink Lifting, which uses high-intensity focused ultrasound to tighten the body line, is also very effective for tightening upper arm fat. If I receive Body Shurink treatment at Maypure, I would like to know how many shots are typically required for both arms combined to firmly lift the sagging skin. I would also like to check in advance if severe bruising or swelling occurs after the procedure, causing it to be very noticeable when wearing thin clothing.
