I received all 5 rounds of Potenza.
Potenza is a fairly powerful laser. After doing it, I feel a bit dry for a month.
So, I think it is best to receive it together with a skin booster (especially Rejuran Healer recommended) if possible.
It hurts a little when I receive it, but it is effective. It feels like it is quite tightening.
I also received a mix of shrinks in between.
If you want soft skin, I think it would be a good idea to try it.
