A few years ago I got a fat-dissolving injection for the abdomen... I think the name was Oppeira? Right after the injection, something kind of sloshing filled my abdomen, so my stomach looked even more bloated than usual, and I thought, since they said the fat would come out with urine, it would go down after a while. But in the end, there was really no effect at all...
After that, someone asked on the Gangnam Unni app whether the Oppeira injection worked, and when I replied that it did not work for me, my comment got deleted and I even got some warning message sent to me. Thanks to that, my impression of both the clinic and the app got worse.
