Would it be better to choose one specific skin concern before getting Rejuran or a skin booster?

My skin is dry, so I can see my pores and I'm worried about fine lines.
When I search, it feels like I have to do this and that.

However, since the expectations for each skin booster differ slightly,
I realized that blindly trying to do many things at once would actually make the choice more difficult.

Recently, there has been a lot of talk about the importance of choosing products based on your skin condition and purpose.
If this is my first time, would it be better to decide on the one concern that worries me the most and consult with them?
