First step: Facial Assesment

It is frequent to find patients who know well their needs, and they can clearly explain them on the first appointment, but in other cases, the patient asks for an assesment to give advice on the best treatment options.
I have to say that the consultation is the most important moment of the appointment, because it is in that moment when the priorities are settled, the needs are assesed, and the protocol for the treatment is established. This moment accounts for a great  part of the outcome, probably as much as the technical proceedure, because without a good preliminary assesment the outcome will not be good.
As doctors, the assesment is the moment of diagnosing any aditional condition that might be present, and will interfere with the result. As for example, any asymmetry, scar, pigmentation, or even pathologies, that need to be considered at the begining.  
As a consequence of the assesment, the treatment plan might need to be changed, or the patient might need to reconsider the expectancy of the outcome. 
The medical history must also be reviewed at this point looking for contraindications for the treatment. It is not so unfrequent that after a carefull assesment, contraindications turn up when obtaining the past medical history, and then all the assesment will need to be reconsidered, or even discarded.
