How many times do I need to treat inner dryness and cheek pores?

I am considering a skin booster because of internal dryness and enlarged pores on my cheeks, so I am writing to inquire about how many sessions are typically required.

My skin is oily on my nose but dry on my cheeks, and on days when my skin condition is poor, my pores and rough texture are particularly visible.

Even when looking at photos of my face taken myself, the sides of my nose and the inside of my cheeks feel dry and not smooth.

There are conflicting reports about skin boosters; some say you can feel the hydration after just one session, while others say you need a certain number of sessions. As a beginner, it is difficult to establish a standard. Is it possible to try one session first to check my skin's reaction before deciding whether to continue?

I am also curious how many sessions are usually recommended when there are concerns about internal dryness, enlarged pores, and skin texture.

I would like to know if I need to continue receiving treatments every month after a certain number of sessions, and if I can extend the interval between maintenance treatments if my skin condition improves.
