How effective is Rejuran Skin Booster?

Lately, my skin texture looks rough and I'm concerned about my pores, so I'm looking into Rejuran Skin Booster.

There are a lot of reviews saying it works well, but I'm hesitant because I've also heard there is pain.

I'm curious if I bruise a lot since it's an injection procedure, and I also want to know how long the swelling lasts.

I'm also wondering if I can apply makeup right away.

I'm also wondering how many sessions I need to see results. I'm hesitating because I've heard that you can't see results after just one session.

I'm curious to know how it went for those of you who have tried it to improve your skin texture. It would also be helpful if you could let me know if it's suitable for sensitive skin.
