It felt like the fat-dissolving injection was more effective on the underarm area first. My upper arms also seem to be gradually reducing, not dramatically, but slowly. That change alone became a motivation for me to stay focused on dieting. There was a promotion applied since we went as a group. If two additional people joined, one area was free, which was a pleasant part of the experience. For reference, my mother also received treatment on her double chin, but she did not feel much change there, possibly due to skin sagging. One difficult part was the waiting time. At first, I was told there might be a long wait, and although they offered a swelling-prevention drink as a service, it still took over two hours for a procedure that lasted about ten minutes. My appointment was at 14:00, but I left the clinic around 16:20. The procedure itself was more painful than expected. It was not something I could go through quietly. Also, the gauze tape applied afterward had very strong adhesive strength. Removing it caused pulling on the skin, and I ended up with bruise-like marks in a few places. For about three days, the area where the tape was removed looked dark, and afterward, it appeared as clear pigmentation, almost as if the skin had peeled. Since my skin is sensitive, that part stood out to me.
