What is the typical treatment cycle for Vitaran?

I am writing to inquire because I have become interested in the Vitaran treatment offered at Maypure, a skin booster containing salmon extract. Lately, my skin has felt very dry and lacked elasticity, and I feel like fine lines are forming, so I have been looking for a treatment that improves the skin barrier and replenishes moisture. I heard that Vitaran, being a PN ingredient, is excellent for skin regeneration and resolving internal dryness, so I am planning to give it a try. Since it is an injection treatment, I am wondering how many consecutive sessions are typically required to see proper results. I would also like to know the recommended treatment cycle—that is, the time between sessions. Because of my work schedule, I would also like to know in advance how long marks such as embossing, needle marks, or bruising on my face last after the procedure. I look forward to a detailed response!
