How long does the pore-minimizing effect of Potenza last?

I am looking into Potenza because my pores are getting longer vertically.

I've read reviews saying it uses high-frequency heat to tighten pores, but honestly, for those of you who have tried this, how long do the effects last?

Dermatological procedures are actually quite expensive, and I've heard that pores can widen again if not managed properly, so I haven't been able to make a decision yet and haven't been able to go.

I'm worried because getting the basic treatment takes quite a while, and even though I work, I barely manage to find the time to complete the recommended sessions—whether 3 or 5—only to have it go back to how it was in just two or three months. It would feel really pointless.

Is Potenza a procedure where the effects last long enough to make the cost worthwhile in terms of value for money and satisfaction?

Additionally, please let me know how often I should schedule follow-up treatments for maintenance after receiving Potenza.
