My skin is cracking deep inside; what is the usual price range for Vitaran?

Lately, my face feels like it's going to shrivel up. The surface is shiny with sebum, but there is absolutely no moisture deep inside, to the point where I'm afraid to even open my mouth wide to laugh. Pouring ampoules on hasn't helped, so I'm eyeing the salmon injection treatment, which is considered the top tier solution for combating inner dryness. Since they say it regenerates the skin's environment to make it stronger, I felt I absolutely had to get it. However, I heard that you can't just get it once and need at least three sessions. I'm curious about the approximate pricing of Vitaran based on a 3-session package. If the results are good, I'm 100% willing to pay in installments with a credit card, but I need to know the average market price of Vitaran so I don't get ripped off during the consultation. Those of you who have successfully resolved inner dryness, please share some tips on whether I should budget a generous amount for Vitaran!
