Inquiry regarding the number of Body Shrink shots for shaping sagging skin on the inner arms

During the summer, I am very self-conscious because the skin on the inner upper arms jiggles and sways whenever I move my arms while wearing sleeveless tops. No matter how hard I exercise my arms, the fat in this area doesn't seem to come off easily, and it feels like my skin is just losing elasticity, so I have started considering professional treatment. I heard that Body Shurink Lifting, which uses high-intensity focused ultrasound to tighten the body, is also very effective for tightening upper arm fat. If I receive Body Shurink treatment on my arms 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.
