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 underneath, so it’s to the point where I’m afraid to even open my mouth wide to laugh.

Even pouring ampoules into my skin didn't help, so I'm planning to get a salmon injection, which is considered the top tier treatment for combating inner dryness. I heard it regenerates the skin's environment itself to make it strong, so I felt like I absolutely had to get it.

I heard that you shouldn't get it done just once and need at least three sessions. I'm curious about the approximate pricing of Vitaran based on a 3-session package. If it works well, I'm 100% willing to pay in installments with a credit card, but I need to know the average market price so I don't get ripped off during the consultation. Those of you who have resolved skin tightness, please share some tips on whether I should budget a bit generously for Vitaran!
