I'm in my 40s and concerned about the corners of my mouth and nasolabial folds; I'd like to know what to check before a filler consultation.

As I enter my 40s, I hear a lot of people saying that the corners of my mouth and nasolabial folds are starting to become visible even when I have a neutral expression, so I am looking into filler consultations. I have heard that nasolabial folds are related to sagging cheeks and skin elasticity, so I am curious about the criteria used during the consultation to determine whether to manage them solely with fillers or combine them with other methods. My biggest concern is that the area around my mouth might look unnaturally puffy or look awkward when I smile, so I would like to know how the injection sites and amounts are determined to achieve a natural look. I would also like to confirm in advance whether the duration of the effect varies depending on the type of filler, how long bruising or swelling typically lasts after the procedure, and when I can return to work or wear makeup. Would it be helpful to share my usual facial expression habits or any medications I am currently taking during the initial consultation? Please also let me know if there are any questions I should prepare before the consultation. The attached image is an AI-generated reference image.
