How are the effects of Vitaran on wrinkles and internal dryness?

Lately, I keep getting fine lines around my eyes, and my skin feels like it's cracking all over, so I'm thinking of getting a skin booster.

At first, I was planning to get Rejuran, the most famous one, but I was a bit scared because I heard the pain is too severe. After looking into it, I found out about a procedure called Vitaran that is said to be less painful. Since it is a salmon-based injection, I heard it is good for skin regeneration and hydration, so I am interested in it.

I'm curious if the pain is bearable compared to Rejuran. Is it tolerable if the numbing cream is applied properly? I would also like to know how many days the raised needle marks last after the procedure.

I would also like to know if I can feel the relief from internal dryness or improvement in fine lines after just one session, or if I usually need to get treatments at intervals of a few weeks to maintain the effects for a long time.
