Is there a specific recommended frequency for Vitaran?

I first learned about a procedure called 'Vitaran' after I started attending Maypure. I heard that it helps with regeneration because it contains PN ingredients, just like Rejuran. My skin barrier is thin and sensitive, and acne scars tend to linger for a long time. In other words, I believe my regenerative ability is lacking, so I am considering Vitaran.

Actually, when I received Rejuran, the results were great, but I had a slight allergic reaction, so I was debating whether or not to get it again. I was also thinking that it might be good to try Vitaran, which is a bit different.

But another thing that concerns me is that skin boosters have a long downtime. I was told that Rejuran requires at least three sessions, so I only got one and couldn't get any more. Does Vitaran also have a recommended number of sessions? Would it be difficult to see results with just one or two?
