This was my first treatment! I made a same-day phone appointment and asked whether I could receive the app's first-treatment price, and they said yes.
There were two people waiting, and I spent about 30 minutes waiting. The coordinator conducted a fairly thorough consultation. However, I went in knowing so little that I am not sure how much of it was actually helpful. I remember being told that my masseter muscles were quite developed, so jaw Botox would be effective; they also recommended a lifting treatment, and otherwise did not mention any particular additional procedures. They also answered my questions about side effects and resistance.
In the end, I received the basic dose plus an additional amount. After applying numbing cream for about 15 minutes, I went in for the treatment. The doctor performed it for about three minutes, taking asymmetry into consideration.
It is still too soon to judge the effect, so I will edit this and leave an update as soon as it becomes meaningfully visible. It was my first treatment, and everyone was quite kind.
