What criteria do you use to research Botox?

Recently, my facial expression lines have started to become more noticeable, so I looked into ways to manage them and ended up looking into Botox. In the past, I only considered makeup or home care, but since I become self-conscious about specific areas whenever I take photos, I became curious about other methods. However, Botox reviews are so varied that I'm not sure what criteria to use when choosing a clinic and getting a consultation. I think it's important not only to get an explanation of the Botox itself but also to be able to fully discuss the natural look I want. Since this is my first time, I also want to know in advance about the procedure and what I need to pay attention to in my daily life afterward. For those of you who have received Botox, what was the most satisfying part of your consultation? Conversely, I'm also curious if there is anything you wish you had asked about beforehand. Please share your experiences that would be helpful to someone like me who is looking into this for the first time.
