I had had injections there before, then stopped going for a while because of COVID, and went back after making a reservation after a long time. After sitting for a bit, they consulted me right away, which I liked because they didn't try to push any extra treatments.
I sat in the middle waiting room for a bit again, then went straight in for the procedure. They showed me the botox vial I had chosen and opened it right there, and the doctor came and injected it.
They didn't just poke in roughly; they were delicate, and the injection seemed to be administered more slowly and carefully than before.
I think the effect will naturally be good, since I had it done before.
