Is the effect good after just one use of Potenza Pore Cleanser?

Once I started worrying about the pores on my butterfly zone, it annoys me so much every time I look in the mirror! Now there are also slightly indented scar-like spots next to my nose, so my makeup looks really unflattering. As far as I know, Potenza is the most famous brand for pore treatments; would just one session be effective?

Since I work, it is difficult for me to schedule multiple sessions of treatments like Potenza that have a downtime, but if there is some degree of pore-shrinking effect after just one session, I am thinking of giving it a try.

I know that Potenza #3 is the standard... but I'm still curious if anyone saw results with just #1, and what tip you used for pore tightening!
