Is a separate consultation fee charged when visiting a dermatology clinic for the first time just for a consultation?

I would like to get a skin condition check or a consultation for the procedure first.

I am wondering if there are separate medical or consultation fees even if I leave after only receiving a consultation or diagnosis without deciding on the procedure on the same day.

Is it possible to receive counseling, schedule an appointment, hear an explanation, and then leave without treatment?

Do you tend to start with a simple prescription or treatment on the first day?

For those who only visited the dermatology clinic for a consultation, please let us know how the process went.
