How long does the effect of Pico Toning usually last?

As I entered my 50s, I noticed an increase in blemishes and pigmentation on my face, which sparked my interest in skincare. I received recommendations for Pico Toning from those around me and am looking into it, but I am most curious about the duration of the results rather than the procedure itself.

I have heard that Pico Toning improves skin tone, and I would like to know how long the effects typically last. I am also curious whether the results are maintained after just one session, or if regular treatments are necessary. Additionally, does the duration of Pico Toning vary significantly depending on age or skin condition?

I play golf frequently and spend a lot of time outdoors, so I am exposed to a lot of UV rays. I am wondering if these lifestyle habits affect the duration of Pico Toning results. I would like to hear experiences or advice from those who have actually received the treatment.
