Will I feel a difference even if I get Rejuran when my skin isn't particularly bad?

Lately, my skin hasn't been breaking out badly or having a lot of breakouts, but sometimes it looks overall drier and duller than before.

Although makeup covers it to some extent, my skin feels like it looks tired quickly by the afternoon.

I would like to know if Rejuran is a procedure necessary only for people with severely damaged or dry skin, or if it is also meaningful for those who want to manage their skin condition even without major issues, like I do now.

I'm also curious if there are people who can feel a difference in their skin condition after just one or two sessions.
