How many times is it recommended to use the collagen booster to see results?

I am considering a collagen booster because of enlarged pores on my nose and cheeks, as well as my rough skin texture. I am wondering how many sessions are usually required.

I know that pores won't disappear with just one treatment, so I'm not expecting a perfect transformation; I just want my skin to look a little firmer and smoother than it is now so that my pores are less noticeable.

I am also curious whether I can feel the effects of the collagen booster after just one session, or if I need to receive a cumulative number of sessions to properly assess them. Rather than deciding on multiple sessions right away, would it be okay to try the collagen booster once to check my skin's reaction before deciding on additional treatments?

I am also curious whether the collagen booster cycle should be short, like every week, or if there should be a gap of a few weeks. My skin tends to redden easily, so I want to manage it slowly with a manageable frequency and interval.
