Do you really feel your skin improving after getting Rejuran injections?

I've been getting so many recommendations for Rejuran from people around me that I've become interested, but since it's quite an expensive procedure, I can't easily make a decision.

When I read reviews, people say their skin texture has improved and feels healthier, but on the other hand, there are also those who say they didn't feel as much of a change as they expected, so I'm still debating.

In particular, I have heard that Rejuran requires multiple injections to show results, so I am curious if the satisfaction is truly worth the cost.
