How many sessions would be best to assess satisfaction with the recommended number of Livicol sessions?

I am writing to inquire about the recommended usage frequency and satisfaction levels for Rivicol. There are so many types of skin boosters that it is really hard to decide which one to choose haha.

My biggest concern is that my skin looks dry and lifeless, and up close, the texture appears rougher than before. People around me say that consistent care is more important than treatments that show dramatic changes all at once to make the skin look good, but as someone just starting out, I am wondering if Revicol is a good choice.

Is Rivicol better suited for concerns like inner dryness, fine texture, and roughness?

Alternatively, could I also get a consultation regarding pores or loss of elasticity? I would like to know how many sessions of Revicol are generally recommended to gauge satisfaction. I am also curious whether I can feel some change in my skin condition after just one session, or if I need several to make a judgment. I don't want my face to look completely different; I just want my makeup to apply better and my skin to look less tired.
