If I am considering Sculptra, should I start by defining the face shape I want?

I feel that there is a lack of volume, but it is not easy to explain exactly which areas need to change and by how much to be satisfied.

It seems that the approach to simply filling in the sunken areas of the face is different from considering the harmony of the overall contours.

Would it be helpful to organize the changes I want in photos or notes before the Sculptra consultation? I would like to know how improvement goals are determined during the actual consultation.
