[Botox] Square jaw Botox side effects

I decided to go to The Face Plastic Surgery Clinic in Busan and went to the hospital. There were a lot of people and there were a lot of people who were angry because of the long wait.. I was told that I had to wait about 30 minutes longer than the reservation time, but I was very angry because I was waiting for about 2 hours. When my turn came, I went downstairs, and a person who I didn't know whether it was the manager or a nurse informed me of the price and type, looked at my face, and told me to wait. Don't they usually provide consultations for Botox? Then, he called me in and told me to lie down without even looking at my face, and he tried to give me an injection right away. I told him that the muscles in my jaw were different on both sides, and then he pretended to look and asked me if I had seen him for 5 seconds. I think I just did the same thing. So, I ended up having a side effect where the corners of my mouth didn't go up. I thought about placing it too far forward, but I can't help it because I already injected it. I'm just waiting for the Botox to wear off. I put it in with a real factory type. It was my first treatment with the next person, but I was disappointed. It's too big ㅠ
