They are good at dissolving filler.
I went with high expectations because I heard they were famous. When I tried to show the design I wanted, they told me to bring a pre-procedure photo of that design and made a stern face. I had a lip design I wanted, so I lifted the mirror once to see if it was going well, and the way they told me to put the mirror down because they could not concentrate is still vivid in my mind. It would have been nice if I had at least been satisfied after the procedure, but not only did the design I wanted not come out, something went wrong and my nasolabial folds became much worse, so I spent all that money and had it dissolved right away after 3 days…
