For those who say their skin texture improved after just one Rejuran session, did you really see results?

My skin has been unusually dry and dull lately, and there have been many days when my makeup looks patchy, so I am looking into Rejuran.

At first, I thought it was just a water-glow injection, but the more I looked into it, the more I heard that you need to receive about three sessions consistently rather than just one to be satisfied.
However, the cost isn't exactly cheap, so I'm hesitant to just start doing it multiple times without careful consideration.

Especially since my main goal is to improve fine lines and skin texture, I think I would be satisfied if my skin condition just improved compared to before, rather than seeing dramatic changes.

Please share your experience regarding whether you were satisfied after just one session, or if you needed multiple sessions to see a definite difference.

For those of you who have received Rejuran, at which session did you start to notice changes?
