How long does the Vitaran procedure take?

My skin is so dry and brittle like a desert, I need to get an injection for internal dryness.

I would like to make an appointment and go after work, but I am wondering approximately how many minutes the Vitaran procedure itself takes, excluding the time for applying anesthetic cream and waiting.

I'm impatient, so I really hate it when things take too long lol. I wonder if it gets finished quickly if I meet a director with fast hands.

Or perhaps it takes a long time because of the meticulous craftsmanship involved in Vitaran. Those of you who have completely resolved inner dryness with a short Vitaran treatment, please help me calculate the time!
