It's been two weeks since my second 2cc Rejuran session, but I still don't really see any effects.

I started Rejuran because of my skin texture and mild dryness, and I received 2cc twice.
I didn't really notice anything after the first session, but after the second, my skin seems a little firmer, though I don't see any huge changes yet.
It has been about two weeks since the procedure. Is it normal for Rejuran not to show immediate effects and to take some time to show results?
For those who have completed up to the 3rd session, I am curious at which week you started noticing definite effects on your skin texture or pores.
I would appreciate it if you could also let me know whether you received 2cc or 4cc!
