How are facial expression movements and dosages for each area checked during a Botox consultation?

I am curious about the criteria used to assess the condition of areas with different movements, such as the forehead, glabella, and eye corners, during a Botox consultation. I would like to know if the treatment plan is planned by differentiating between muscle movements during facial expressions and wrinkles when at rest, and by examining differences between the left and right sides. If this is my first consultation, how should I explain the desired degree of change and my concerns? I am also curious if the precautions before and after treatment differ if my skin is dry or sensitive. I would like to know if temporary swelling, bruising, or discomfort may occur after the procedure, the expected duration of the effects, and the criteria for contacting the clinic. I would also like guidance on when to avoid exercise, saunas, and alcohol, as well as when I can wash my face and reapply makeup. Please explain when to evaluate the effects, the criteria for deciding on the next treatment, and whether the recommended interval varies by area.
