This is what I have heard, yes! Some clinics will do pictures and adjust them to show you want it would look like from various angles. It makes it easier to get an idea of what you'd see when looking in the mirror.
It is okay! A lot of people don't know about this unless they speak with a doctor or are working with clinics to find options. You might be better off doing botox to help plump things up and wait until you are a bit older before doing this?
