How many times do I need to get Vitaran to see its full effects?

Lately, my skin feels like my barrier has compromised, making it sensitive and severely dry, so I was recommended Vitaran, which contains salmon extract. I heard it is less painful than Rejuran, so I am trying to muster up the courage to give it a try, but I am curious if it will actually show the effects I am hoping for. I saw reviews saying it relieves inner tightness and brightens skin tone; will I see noticeable results after just one injection?

I've heard that you usually need about three sessions at one-month intervals to see firm results, but I'm hesitant because the cost is quite steep. I would also like to know if bruising or swelling on the face lasts a long time after the Vitaran procedure. I have an important appointment next week, so I'm worried about whether I should get the treatment before then. I would appreciate some warm advice from those who have successfully recovered their skin condition! I really want to get flawless skin this time!
