I have my 3rd Rejuran session coming up. Do I need to get the same dosage as the 1st and 2nd sessions?

I received 3cc for my entire face for both my first and second sessions, and I am debating whether to get the same 3cc for my third session. I was satisfied with the improvement in my skin texture and internal dryness, but honestly, the procedure itself was really painful for me. It was especially painful on thin areas like my forehead and chin, to the point where it almost brought me to tears. Still, it was a bit more bearable than the first session because they applied anesthesia for a longer time during the second. Is it common to get 3cc for the third session as well, or has anyone tried receiving a different dosage?
