How often do I usually get Pico Toning treatments?

I am writing to inquire about the Pico Toning cycle. Lately, I have been noticing brown marks on my cheekbones that are hard to tell if they are melasma or blemishes, and they seem to be getting darker little by little. While looking into laser treatments, I came across Pico Toning.

I used to be able to cover it up to some extent with makeup, but lately, even when I apply a thick layer of cushion foundation, it feels like dullness is coming up from deep within, which is actually quite stressful. I've seen a lot of posts saying that Pico Toning isn't a one-time procedure but requires consistent treatment over several sessions. How often is the typical interval for Pico Toning sessions scheduled?

My skin is on the thinner and drier side, so I'm worried that getting treatments too often might make it sensitive, but I'm also concerned that the results might be slow if I space them out too far. I'm also curious how many sessions people usually plan to start with Pico Toning for the first time.

I would also like to know if you determine the Pico Toning cycle and number of sessions based on the type of pigmentation during the consultation.
